PIAS was adapted around 2015 so that more than two calculation cores can be used in parallel.
In view of the overhead time involved in starting up a separate calculation task, a maximum of 8 simultaneous calculation tasks was chosen at the time.
Meanwhile, multithreading has been implemented in even more places within the PIAS for lengthy and compute-intensive tasks such as:
• probabilistic damage stability: the optimization of the damage boundaries.
• probabilistic damage stability: the generation of damage cases.
The last few years multi-core computers have become widely available and there are now PC‘s available for the common user which have ten or even more cores, where hyperthreading allows twenty or more threads to run simultaneously. Especially with time consuming calculation tasks, such as the ones mentioned above, the overhead time hardly plays a role and one can gain a considerable amount of time by calculating with more than 8 threads.
Therefore, the maximum number of parallel processes within PIAS has been increased from eight (octothreading) to twenty (vigintithreading).
To give the user a clear insight in the use of multiple threads, especially in time consuming calculations and in combination with vigintithreading, PIAS has been extended with a thread monitoring interface. This interface is visible during the calculations and shows relevant and real time information per thread, such as: information about the status, i.e. a description of the current task of the thread, start time and elapsed time. This thread monitoring interface is also available for single-, dual- and octothreading.

SARC has provided multiple licenses of PIAS to DNV GL Hamburg and Gdynia office.
DNV GL is an international classification society from Norway/Germany and has around 350 offices operating in more than 100 countries. DNV GL is the world’s largest classification society and is now able to approve stability booklets and on-board loading computer software with our PIAS software.
“After we have now purchased PIAS for our Poland/Gdynia and our Germany/Hamburg offices already, I would like to thank you and your whole team for the efficient and friendly workshops and the excellent support during our more than one year lasting PIAS trial phase. We are strongly looking forward to cooperate further with you in the same way.” said by Jan Wilkens of DNV GL.
In the build-up to the purchase of PIAS, DNV GL first tested the software extensively and there were several in-house courses to make sure they use the software in the best possible way. Various trained naval architects of SARC will continue to provide support via e-mail or telephone when necessary. Because DNV GL now uses PIAS, the cooperation between the DNV GL and SARCs has become even better. This will also be beneficial to other PIAS users who submit their stability calculations to DNV GL for approval. Now the approval process will probably run even smoother.

On May 1st, 1980, Herbert Koelman started a small company named SARC from his attic in Delft when the computer age was still in its infancy. You probably know the story from there: SARC currently employs 14 enthousiastic naval architects, we have done some 4500 projects, we have delivered some 1300 versions of LOCOPIAS, while PIAS is “world famous in the Netherlands and its wider surroundings”.
We have accomplished a lot together during our first 40 years. But what matters most is that we remain confident for the future, while we continue to work on new services and software features . Thank you for helping make SARC a fantastic company now and for decades to come.

In the last few years SARC and CADMATIC have joined forces to develop a collaborative ship design system together with Conoship. This collaboration has been called the Dutch Collaborative Platform for the Design and Engineering of Ships (CPDES) research project.
In the early design stage, most small and medium-sized shipyards and design offices have difficulty controlling consistency when exchanging the ship’s arrangement and hull data between the 2D General Arrangement (G.A.) plan and stability analysis tools. The exchange of design data is often done manually and it can take days to implement design changes like repositioning decks or bulkheads in the G.A. plan and analyzing the effects on the various design calculation applications. Performing damage stability calculations very late in the basic design process, for example, often involves a lot of rework and increased building costs if the design does not fulfil the requirements.
Time-consuming design data exchanges and managing the consistency of design data are designers’ main challenges. Therefore, uniform, modern data exchange interfaces between early design software tools and steel design software tools are very beneficial.
With a focus on bulkheads & decks, compartments and piping, we created a V1.0 implementation, which covers intensively used data and actions, as well as a comprehensive manual and other instruction materials.
SARC and CADMATIC achieved the following for bulkheads and decks:

Container ships navigating the major European inland waterways should comply with the ES-TRIN 2017/1 standard. Since the 1980s PIAS contains a dedicated module, named Rhine, for this regulation (and its predecessors). This module has now been discarded, for all its functions have been relocated to other PIAS modules.
All input can now be done with Hulldef, the applicable stability criteria can be set in the regular fashion, while Hydrotables will produce the required table of maximum allowable VCG.
As alternative to the approximation formulae from ES-TRIN, it is now also possible to compute the maximum VCG with direct calculations on basis of the foundational stability criteria.

Since its childhood, PIAS had the feature of an easy definition of upper appendages, such as deckhouses or camber, where manual commands were used to explicitly add or remove the appendages to or from the hullform. With the latest PIAS version this user command is not required anymore; once appendages have been defined, they will automatically be incorporated in the hullform, in accordance with their most recent definition.
Please be aware that in order to accommodate this new modus operandi, the file format containing the frame shapes has been updated. As usual with PIAS, conversion from old to new format is done automatically, without user intervention. However, it will be evident that elder PIAS version cannot read the new format, so in order to be prepared for the new format it is recommended to download and install the most recent PIAS version.

The PIAS module Resist, which can predict resistances of different ship types with nine published empirical methods, has been expanded with a shallow-water correction. The implemented method is based on H.C. Raven, “A new correction procedure for shallow-water effects in ship speed trials”, Proceedings of PRADS2016 (2016), Kopenhagen, Denmark. In 2017 the ITTC has accepted this method, and now it can be used in Resist to predict the increase in resistance when sailing in shallow waters.

The 2020 edition of the intact stability code has been extended with, among other things, regulations on the maximum allowable chain force for anchor handling vessels. The implementation of these rules in PIAS has been released on August 21, 2019. This calculation involves many iterations and decompositions of anchor forces, much too many to be included in output. In order to gain some insight in the calculation flow, one of the PIAS users ordered at SARC a manual elaboration of the calculation steps for one particular test case. This client was so friendly to allow copies of this document to be distributed to other PIAS users. You can contact us if you are interested in such a copy.

Earlier this year we have sent our customers information on the upgrade of our software license protection mechanism from the hardware lock brand “Sentinel” to the Codemeter license.
Early next year we will switch permanently to the use of the Codemeter implementation.
After this date you can still use the sentinel, but if you want to change something to your license, you need to switch to the Codemeter first. For this switch below mentioned costs are applicable.
The PIAS software license is currently protected by means of a hardware lock and for the past decades we have used a lock of the brand “Sentinel“ for this.
We have come to the day that the sentinel does no longer provide us with sufficient means to meet the demands of both our customers and ourselves for a more and more flexible license administration and management.
Therefore we have decided to implement a new type of hardware lock named Codemeter, provided by Wibu systems.
The Codemeter implementation has the following main advantages and benefits;
The use of the Sentinel is still supported, but will be phased out in the near future. New developments will only be available with the new Codemeter implementation. So although the sentinel remains supported for some time, we urge you to make the switch to the Codemeter implementation now.
From January 2020, changes to your PIAS license using the sentinel will require an update to the Codemeter implementation.
Please contact us if you want to use the temporarily offer, or if you require more information.

Different regulations are used for vessels with designation Anchor Handling:
These rules, though sharing a similar purpose, prescribe different formulae for the forces and moments to be taken into account when assessing stability for anchor handling vessels. The results of these calculations can be expressed in tables of allowable anchor chain forces, or in a polar plot of maximum allowable anchor chain forces for a given loading condition.
SARC has implemented both polar plots of allowable anchor chain forces (for a given loading condition) and the tables of allowable anchor chain forces for the first 3 of the requirements listed above. Still, many questions are asked because results may sometimes conflict with users’ expectations. Additionally, some of these rules include some formulae of which the purpose and background are obscure.
Just as for other complex stability calculations, SARC will offer a workshop/training on the ins and outs of above rules.
The following subjects will be presented:
If you are interested, please contact SARC for further details. The first workshop is planned on December 13 2019, from 10:00 to 16:00 in Bussum, the Netherlands.

To speed up time consuming calculations (more specific, parts of the probabilistic damage stability calculations), PIAS uses parallelization of the calculation process where possible. For example the generation of damage cases and the calculation of damage boundaries is multithreaded.
Multithreading in PIAS is available as dual-threading (up to 2 cores), Octo-threading (up to 8 cores) and will be available soon in Viginty-threading (up to 20 cores).
Up till now, the feedback of the application during the calculation progress was limited. To improve this feedback, PIAS has been extended with a thread monitoring interface, which gives detailed information on the status of the available, and working threads. A print screen of this interface is shown in the picture below.

A select set of frequently used functions in Fairway are now just one click away, directly accessible from the new tool bars. Tool bars in Fairway can be rearranged by dragging them to a different location around the drawing area, or floating anywhere on top of the drawing area. Individual tool bars can be hidden and shown by right-clicking on the tool bar area or from the [Window -> Tool Bars] menu. Users that prefer to activate functions using <Alt> key combinations instead may be interested to switch all tool bars off, which will give them a bigger drawing area.

It will be well known that for the definition of spaces and compartments in PIAS, the ‘physical planes’ provide a very efficient modelling tool. Obviously, these planes will in practice be used to model bulkheads and decks.
Recently, the data storage of the physical planes has been enhanced to include a specific weight (which is the average weight of the plane in ton/m2). This is used in a new feature, labelled ‘Area table’, which includes for each plane its area, CoG and weight. At the end of the table total weight and CoG is listed.
Although this table provides only a rough approximation of the internal steel hull weight, it is still a useful tool in the early design stage, because it is so tightly integrated with the design model of the internal geometry. At present, the shell weight is not included in this list, although the weight and CoG of the shell plates can be computed with the shell plate expansion function of Fairway.

IMDG amendment 39-18 is now published, may be used from 1/1/2019 and becomes mandatory on 1/1/2020 when amdt 38-16 is no longer valid. The overview of changes has been published by Hazcheck: http://www.imdgsupport.com/IMDG_2018_Changes.asp
Last year we released the IMDG module for the first time. Now SARC has integrated the IMDG Amendment 39-18 into the LOCOPIAS IMDG module. The updated module is available and ready to be delivered. If you would like to request the updated LOCOPIAS IMDG module (IMDG Amendment 39-18) now, please send us a message.

IMO Intact Stability Code is in its 2020 version extended to include a section 2.7, “Ships engaged in anchor handling operations”. These have now been added to the rule set of PIAS’ Maxchain module, as well as in the polar plots of LOCOPIAS.

Those who followed the newsletters of the past years will have noticed that PIAS has seriously been revised and modernized.
An important topic in this process has been the replacement of Compart with the Layout module. However, PIAS modules using compartment data were still based on the Compart data format, so Layout stored the compartment data both in native Layout format, as well as in Compart format. For the user this was invisible, so as such it was no real objection, but this duality obstructs further software developments. For this reason, all modules of PIAS have been adapted to native Layout format. This new software has been in use within SARC for some time, and has been intensively tested, so we consider it now to be the time for a general release. Actually, you will not see any change in operation of PIAS, although compart-related computations (such as damage stability) might occasionally give marginally different results with the new software. Please be assured that, thanks to the enhanced compartment definition method of Layout, differences — if they occur at all — will be in the direction of increased accuracy.
Compart has been removed from the set of PIAS modules. An act that we will perform with some melancholy because this piece of software has since 1985 served thousands of PIAS users with modelling and computations of an estimated million tanks, holds and spaces.

On June 15, 2018 IMO adopted resolution MSC.421(98), titled “Amendments to the International Convention for the Safety of Life at Sea”. With respect to probabilistic damage stability, this encompasses:
PIAS module Probdam has been extended with these changes and is currently being tested. From July 1, 2019 this functionality is available for all users of Probdam.

When designing or defining a ship for some tanks or compartments target capacities apply. In those cases it will be convenient to have permanent feedback on the actual volume of a compartment. This feature is now available in PIAS’ Layout module.

The output of damage stability (summary) has been given a makeover and has become much shorter than before. This output can also be imported into Microsoft Word or Excel to edit it yourself. For each damage case it is now possible to see briefly and clearly whether this case is complies or not. The complete output has remained unchanged and everything can be found there down to the last detail.

Already for some twenty years, the Probdam damage case generator has a feature, called compartment connections, for generating complex intermediate stages of flooding. This tool has been improved so that a multitude of complex intermediate stages will be generated, instead of just a single one previously. This results in a more realistic flooding pattern of compartments through the defined compartment connections. As an example, see the picture below which shows the previous mechanism, as well as the present one. In this example compartment A is initially damaged and compartments B and C are being flooded due to the compartment connections with compartment A.

SARC is already present in the maritime software industry for more than 35 years. Our goal is to create software for naval architects which programmed from the mind and practice of a naval architect, in order to make it quick and easy to use. One of the most challenging parts of software programming is to make the software is fast enough for the most comprehensive calculations. As years got by, on one hand computers became faster, while on the other hand there is a tendence to calculate more and more. Therefore the software programmers had to make sure they would keep up with the developments of the hardware.
For a long time past a PC generally had one processor, containing only a single processing unit (core). That implies that the computer can process one task at a time. However, there is a tendency where a computer is equipped with multiple real or virtual processors. So, this technology enables a program to execute tasks parallel and in 2005 PIAS has been adapted for that facility by making the following tasks available for simultaneous processing:
So, over more then a decade ago we already developed hyper-threading within PIAS. In later years hardware companies kept developing their processors which also led to new developments in our software. Dual threading processors have led to multithreading in PIAS. Additionally, modern CPU’s are equipped with AVX (Advanced Vector eXtensions) which facilitates eight concurrent arithmetic operations in one processor cycle. More information can be found in the white paper ‘Acceleration of PIAS by hardware support‘ from May 2017.
PIAS offers two speed enhancing packages:
We have done some tests for an “average” PIAS ship, with damage cases up to 8 simultaneous damaged compartments, resulting in 525 damage cases, without so-called “external subcompartments”. (Measured timings are in seconds)

Hopper dredger stability (e.g. dr-68 or Bureau Veritas N.I. 144) computation used to be present in PIAS in a separate module Hopstab. In February 16 of this year a new version of PIAS’ stability module Loading was released, where all hopper stability effects have been integrated (and enhanced, compared to Hopstab). The dr-78 and dr-68 stability regulations require a hopper dredger also to comply with requirements of probabilistic damage stability. This has been available for some decades in PIAS, based on the hopper particulars as defined in Hopstab. Recently, PIAS’ probabilistic damage stability module has been updated, so it now applies the hopper and loading data as defined in Loading. The new modus operandi of probabilistic damage stability for a hopper dredger is discussed in the manual.
After this enhancement, module Hopstab has become obsolete and will be discarded. This marks the end of the software renewal process around hopper dredger stability in PIAS, and implies that specific hopper-related data files from elder projects cannot be used anymore for computations. Please refer to the hopper stability manual chapter for further discussion.

For the computation of wind heeling moments, in PIAS the windage area can be given. That used to be limited to a single contour, with some maximum number of points, which was sufficient for the common use the past 25 years. However, when importing the contour shape from a CAD system that maximum can easily be exceeded. For this reason this PIAS’ module Hulldef has been extended to accommodate a wind contour with a number of sub-contours (each with a resistance coefficient), with an unlimited number of points.

Type vessel: General / Bulk cargo for inland waterways
Delivery: Lines plan for a single screw inland waterway vessel.
For Shipbuilding Solutions our engineers performed the lines plan design for a general cargo vessel built for the Dutch inland waterways. They started off with a general arrangement plan and made a unique design for the hull form. Besides the hull form design, they also have faired the vessel with Fairway to optimize the building process.
After designing the vessel there also have been made some Rhine container calculations with PIAS.

Righting (and heeling) levers of stability are determined by dividing the righting (or heeling) moment by the ship’s displacement. In intact condition, the displacement to choose for that division is unambiguously that of the loading condition under consideration. In damage stability, the choice is not that obvious. However, the standard suggested by the relevant regulations has conventionally been “Constant displacement”, so that has always been the standard choice in PIAS. For some time now an alternative choice is also available — as presented in “MSC.1/Circ.1461, guidelines for verification of damage stability requirements for tankers” and “IACS 110 Guideline for Scope of Damage Stability Verification on new oil tankers, chemical tankers and gas carriers” — i.e. “Intact displacement minus liquid cargo loss”. The choice between these two alternatives is now available as a setting in PIAS, please consult the manual for more details.

SARC has successfully delivered the on-board loading computer software for the new cargo vessel Arklow Villa (YN 730). This is the last ship in a series of ten 5,150 DWT traders that SARC has fitted out at Royal Bodewes Shipyard to Bureau Veritas class standards. They are all owned by Arklow Shipping and are being operated and managed by Arklow Shipping Netherlands. The first vessel in the series was be delivered in October 2015.
Bodewes & SARC
This is not for the first time that Bodewes has ordered the on-board loading computer at SARC. Other recent projects like the NB 803 Coralius; a unique LNG flex tanker that was nominated for the Next Generation Ship Award at Norshipping 2015 is also equipped with LOCOPIAS. At Bodewes they are using our PIAS software to calculate the stability of their vessels. The advantage of this is that SARC can use their PIAS-files for the base of LOCOPIAS, so there is no extra costs for input of ship data and the same files are used for the stability booklets.
The launch of the Arklow Villa has been filmed and uploaded to YouTube.

The stability required to ensure the safety of a ship, its crew and the environment is laid down in legislation. In PIAS the major part of legislation is predefined, readily available, while the underlying parametric editor facilities allows the definition of less frequently used or very specific criteria. More information about manipulating and selecting sets of stability cirteria can be found in the manual: https://www.sarc.nl/images/manuals/pias/htmlEN/stabcrit.html.
We have created a document to provide a coherent and clear overview of the stability criteria. This is achieved by collecting legislations set by the IMO, European Union and local authorities, and categorizes these legislations by operating area and ship type. Please send us a message if you are interested in this document including the .req files for PIAS.
Earlier this year we have informed you about the update of the stability criteria within PIAS: https://www.sarc.nl/update-of-stability-criteria-in-pias/ .

Although the NURBS surface method is not very suitable for the hull design process as such, it is widely used for interfacing. So, when a hull design is to be used downstream, e.g. for engineering, CFD analyses or visualization, the Fairway hullform has to be converted to a set of NURBS surfaces.
The first step is identifying larger, four-sided areas, which is essential because its four-sidedness is an intrinsic requirement of the NURBS. The next step is to convert these surfaces to NURBS. In this paper the mathematical nitty-gritty will be omitted, the interested reader is redirected to a special conference paper on this subject.
Anyway, the result is that by some neat mathematical processing, a patchwork of NURBS surface is created with the following properties:
This method is baptized LEANURBS (an acronym for Lowest Effective Amount of NURBS). Its implementation in Fairway is demonstrated by the following sequence of screen dumps, from which the first shows the ship hull in Fairway. The second is a screen dump where the hull is subdivided into four-sided regions and the last one is the IGES file in Rhino.

From January 2018 the new 38th amendment of the IMDG Code will become mandatory and to invigorate this an IMDG module has been added to LOCOPIAS.
IMDG (International Maritime Dangerous Goods) Code is accepted as an international guideline to the safe maritime transportation or shipment of dangerous goods or hazardous materials. This (mandatory) Code has been designed to protect crew members and to prevent marine pollution.
The IMDG code extension in the LOCOPIAS container module assists in the loading of dangerous cargo by real time validation against the IMDG requirements. It presents the operator an overview of conflicts in segregation and stowage requirements. Current implemented version is amendment 38-16 (the most recent version of the code). The complete white paper can be found here.

This manual is intended to explain how to verify the Loading Computer System (LCS). The LCS, in this case LOCOPIAS, must be verified at regular intervals to check the correct functioning of the loading instrument. EBIS is asking for a Class approved ship stability calculation program for on-board use and there muest be records indicating that the operational accuracy of the ships stability calculation program is tested regularly.

Already for some decades, PIAS has the capability to compute intact and damage stability for open-top hopper vessels, e.g. as required by the dr-67 & dr-68 regulations for hopper dredgers with a reduced freeboard. This function, which was available in a separate PIAS module, has recently be integrated in PIAS’ standard stability module, called Loading. With this enhancement the hopper stability computations can now be combined with all Loading’s tools and options, and is now also available for the LOCOPIAS on-board loading software. More details of the new modus operandi can be found in the manual.

SARC is pleased to announce the extension of LR (Lloyd’s Register) Type Approval for their LOCOPIAS on-board loading computer software. This approval certifies LOCOPIAS products for use in LR class ships in the (damage) stability and longitudinal strength of the vessel.
“We are very happy with this certification,” said Herbert Koelman, Managing Director of SARC. “Not only does this help support our ship building and engineering customers, as well as their suppliers, but all of our customers.” Koelman explains, “Having passed the stringent LR approval, is a statement of the durability and reliability of our products.”
LOCOPIAS is on-board loading computer software. Derived from the PIAS ship design software, it uses the same proven technology to achieve optimum loading within the limits for strength, stability, draft, etc. This ensures maximum safety of the vessel, it’s crew, cargo or passengers and the environment. The certificate can be found here.

You might know that IMO is currently developing an additional set of intact stability criteria, the so-called “Second generation intact stability criteria”. It is expected that its development will be finalized around 2019, so it might become sensible to verify some of your ships or designs against these criteria. An occasional PIAS user is already working on that, but for those who lack the time or resources SARC offers this as a service.
Given a ship design and an intact stability booklet, the scan consists of evaluating a number of loading conditions (with a maximum of 5) against those particular 2nd gen.stab. criteria which have reached a certain state of maturity:
The deliverable will be a report with results and conclusions.

One of the goals of the PIB project is to create business cooperation’s and technology transfer between Dutch and Chinese yacht building industry. The PIB-project by RDYC exists of a Road Show program to present the Consortium technology and of a Knowledge-to-Knowledge (K2K) symposium with Universities and industry experts to explore the possibilities of business cooperation’s and technology transfer between the Dutch and Chinese yacht building industry.
The focus of the K2K symposium will be on the yacht design and production process in both countries and to find the similarities and differences.

PIAS’ Layout module is able to produce tank sounding tables with a variety of parameters and units. Commonly, if the ullage or sounding parameters are included in such a table, those are determined in a user-defined sounding pipe, which can exist of two or more points. The latter to model curved or knuckled pipes. Additional, it is also possible to define just a single point, which is then used as the reference point for ullage or sounding. Conventionally, for such a case the ullage or sounding was computed under the assumption that the measuring tape goes through this reference point in a vertical direction. On September 22, 2017, this mechanism has been changed, and now a direction perpendicular to the water plane (so, including the effect of heel and trim) is applied, which is more realistic.

In PIAS, for each particular project of vessel the side of heel for intact and damage stability calculations is user-configurable, where the options are:
The first three options have been available in PIAS from its beginning, the fourth option was added by the end of 2016.
In a separate document Assessment of intact and damage stability to PS and SB in PIAS the background of this feature is described into some detail.
Posted on July 11, 2017
PIAS, as many other stability programs, has from its conceptualization in the 1980s determined the intact and damage stability (or, to be more precise, the GZ) with respect to centerline plane. That is not always correct, in particular with hull shapes which are significant asymmetrical in longitudinal direction the GZ should be determined with respect to a rotated plane (rotated around a vertical axis). Occasionally, people have inquired for a possible extension of PIAS towards the effects of stability around the axis of weakest stability, and the recurring reply of SARC was that this would certainly be feasible, and could be produced on order. In 2017 that was finally implemented in PIAS.
In a separate document Calculation of stability around the weakest heeling axis with PIAS the background of this feature is described into some detail.
Posted on June 27, 2017
Some tasks of PIAS can be quite computation-intensive, such as the computation of intact stability (in particular if enhanced features are active, such as the shift of liquid method, and/or stability around the weakest axis) and damage stability, but also the generation of curved surfaces in Fairway. Time was that each new computer generation was faster than its predecessor, mainly thanks to processor clock frequency increase, but that has come to a halt a decade ago. Nowadays, CPU manufacturers try to stimulate performance gains by means of parallelization, so that multiple tasks can be executed simultaneously. In the recent weeks, at SARC, we have been working to optimize (LOCO-)PIAS with these technologies, with the goal to cramp out all possible performance out of modern hardware.
This resulted for some PIAS applications in a speed increase of a factor 3 to 8, depending on the task and the hardware.
In a separate document Acceleration of PIAS by hardware support the background and results are described into some detail.

A Ballast Water Management Plan must be approved and on board by 8 September 2017. With the deadline approaching, SARC has information and resources to help you. Ships of 400 gt and above are required to have on board and implement a Ballast Water Management Plan approved by Class. The Ballast Water Management Plan is specific to each ship and includes a detailed description of the actions to be taken to implement the Ballast Water Management requirements and supplemental Ballast Water Management practices.
The Ballast Water Management Plan is required to:
The MEPC, at its 71st meeting, reached a compromise on compliance dates for ballast water discharge. Ships constructed after 8th September 2017 must comply on delivery, while existing ships in general must comply by the first IOPP renewal after 8th September 2019.
Under the proposal, ships constructed on or after September 8, 2017 are to comply with the D-2 standard on or after that date.
Vessels built before September 8, 2017, are to comply with the D-2 standard at the first MARPOL IOPP renewal survey completed on or after:

The 16th International Ship Stability Workshop, ISSW 2017 was held in Belgrade, Serbia, from 5th to 7th of June, 2017. During this workshop Herbert Koelman had given a speech about the practicalities of loading instruments for Inland Waterway Tankers.
Intact and damage stability properties of Inland WaterWay (IWW) tankers are being considered to a much greater depth today than they used to be, because the 2015 edition of the applicable legislation not only requires an extensive (damage-) stability manual to be issued, but also an on-board loading computer to be installed. Although the formal framework is set by the rules, there are quite some issues left for interpretation or additional guidance, where also the classification societies play a role. Besides those practical issues, in this paper also data collection, specific loading instrument functions and loading software assessment are discussed. The entire paper can be found in our publications.

In order to accommodate future program enhancements, PIAS’ module Layout has been updated as per May 18, 2017. As usual, this format update is upwards compatible, which means that newer PIAS versions can read the old format, but older versions cannot read the new format. So, in order to be prepared to receive PIAS files in the contemporary format, users are advised to update PIAS at a convenient moment.

Just before the closing of the year we would like to inform you about the most recent developments concerning SARC and PIAS, as elaborated in attached newsletter.
Posted on September 2, 2016
PIAS’ Probdam module is equipped with functions for damage case generation and for the automatic determination of damage boundaries. The algorithm for the latter has been enhanced for two reasons:
The update of this algorithm has three consequences:
A version of PIAS’ Probdam with this enhanced algorithm will be available for download from September 6, 2016.
Posted on August 18, 2016
Although the freeboard calculation module of PIAS is not core of the suite, it is still intensively used in many phases of the ship design process. For that reason we have taken up this module — from which the origin lies 20 years back — and brought it in line with the look and feel of the other PIAS modules. One enhancement is that hullform parameters can now directly be derived from PIAS’ hull model. The applied algorithms remains unchanged, so computation results will not be affected.
Posted on July 27, 2016
PIAS’ Newlay module – for definition of the internal geometry, such as planes, bulkhead and compartments – has been enhanced with a function to compute the area of the outer surfaces of compartments. These figures are intended to serve as a guide for the paint area of compartments.

Since its establishment in 1980, SARC has been using the Good Vibes font for its logo. On May 1st SARC celebrated its 36th birthday, which we consider to be a good opportunity for a fresh logo:
The logo designer has motivated his creation with these words: “A wave is the most identifying visual form that symbolizes water in its purest way. Water is the only constant element SARC always takes into account. Incorporating the wave as the integral part of the letter ‘A’ guarantees such a strong and iconic visual appearance. The logotype – as a typographic only logo – by itself is one of the strongest categories of logos. When executed right, it will become the company’s synonym”. In the curly shape of the A the former seascape of our business cards and leaflets is reflected, as depicted in one of the designers’ design sketches:
A second renewal concerns SARC’s telephone numbers. The general number has been changed into +31 850409040 (although the former +31 35 6915024 will remain in service for some time). Furthermore, each member of the permanent SARC crew can be reached directly, at these numbers:
|Marion Goddijn||+31 850409041|

Finally, also the website has been refreshed. From today it is available at the familiar www.sarc.nl. Essentially, it contains the same information as before, just with a new layer on top of it, which shows in a glance the products and services that SARC is offering. The bottom of the home page contains a brand new animation movie, which shows the world of SARC in 90 seconds.

De afgelopen jaren hebben Numeriek Centrum Groningen (NCG), Conoship en Scheepsbouwkundig Advies en Reken Centrum (SARC) een pilot ontwikkeld waarbij scheepsontwerp- en engineeringssoftware van verschillende herkomst, m.n. NUPAS-CADMATIC en PIAS, zich gedraagt als één systeem.
Om dit concept verder uit te bouwen is, met behulp van Netherlands Maritime Technology (NMT), een voorstel gedaan voor een MIT-R&D-samenwerkingsproject. Dat is recent gehonoreerd, waardoor de ontwikkeling nu in volle vaart verder kan gaan.

PIAS’ internal libraries will be enhanced in order to benefit from facilities of more recent versions of MS-Windows. This implies that future versions of (LOCO-)PIAS will not be able to operate on Windows XP.
For program users who still rely on XP a backdoor will be available for some time. This has internally to be set by SARC, so if you require an XP version please inform SARC.

SARC is to present two papers at the Compit conference this year.
The paper by Herbert Koelman concerns the integration of PIAS with other design tools. Experience indicates that coupling dedicated software packages is a better strategy than trying to develop monolithic “one code fits them all” ship design software.
The paper by Bastiaan Veelo is about the potential application of Fairway, PIAS’ ship hull modeller, to propeller blade design.

The Dutch Government and a consortium of four companies (SARC, Mastership, Polyworx and MHE Engineering) based in Netherlands signed the agreement “Yacht engineering and Design China” on AThe consortium for this Partners for International Business (PIB) project consists of Dutch leading companies of the yacht design and engineering sector. Jointly they can offer to the Chinese yacht builders the know-how, engineering solutions and software tools for all the required disciplines for yacht design and engineering such as steel, aluminium and composite hulls design and construction, piping/HVAC and interior design. The consortium aims to position itself as a preferred supplier for the growing Chinese yacht building industry.
In order to realise this goal, the project partners are supported by the Dutch diplomatic services in China such as the Dutch Embassy, Consulates and NBSO’s. The key activities to be undertaken during the project are:
The project has a duration of two years from April 2015 to April 2017. The focus will be on China South and China North. At the end of the project, the consortium aims to increase the revenue from the Chinese market, both for the consortium partner and other Dutch companies.

The new AND rules of January 1st 2013 include a requirement for stability software on board of a double-walled inland waterway tanker, ADN type-C with effect from 1st of January 2015. A computer loading instrument, covering stability and strength, is required in case the skipper cannot easily determine whether an anticipated loading condition is acceptable from in view of stability requirements. Additionally the stability booklet should contain, among other, information regarding longitudinal strength. However, the most recent news is that as of April 1st 2015, Chemical Tankers ADN type-C should comply with the new rules per to obtain a new or renewed certificates. This should give owners, ourselves and classification societies sufficient time to order, implement and approve the required software and documentation.
SARC has already fully implemented all the new rules of ADN 2015 in LOCOPIAS. We can also provide you with booklets to get approval from any classification society. We provide the intact stability and damage stability for IWW Chemical Tankers.
With regard to ADN 2015, We refer you to the Lloyd’s Register report on this issue at the following link:

LLoyd’s Register EMEA have prepared for an expected increase in work on inland waterway tankers. New ADN and rules and updated EBIS questionnaires now require inland waterway tankers to have stability documentation and loading instruments updated and approved. As the majority of these vessels have been designed with PIAS software, either by SARC or one of many designers using PIAS, SARC has provided LLoyd’s Register EMEA addtional PIAS licences and training of some 8 surveyors in preparation for the huge amount of work involved. By doing so, certification of stability documentation and loading instruments has become much more efficient, as remodelling of vessels is no longer required and LLoyd’s Register EMEA now have larger capacity to check the PIAS models, stability calculations and LOCOPIAS loading instruments submitted for aproval.

Conoship International, ship designers from Groningen, The Netherlands, is a long lasting user of PIAS; way back in the 1980s they belonged to one of the first users of PIAS, so in the past 25 years numerous ships have been designed and optimized with the PIAS tools. Furthermore, Conoship and SARC have collaborated in quite some research and development projects over the past years. However, also innovative companies need efficient off-the-shelf tools from time to time, so we are glad to announce that Conoship has significantly extended her set of PIAS modules.
Some of these extensions are add-ons to existing functionality, such as the optional GUI for the Loading module, while others will provide new possibilities. The latter notably being the Fairway module for hull shape design and optimization, including export options to CFD. However, Conoship International would not be Conoship International if they would not have initiated a few Fairway enhancements which are required to match their specific design method and needs. Those new Fairway features will be implemented in the course of the months to come.

Quoting from the new LOCOPIAS Certificate of Approval issued by Lloyd’s Register:
“This is to certify that the above Strength, Intact (Type 1) & Damage (Type 2 & 3) Stability calculation program has been examined in accordance with the relevant Classification Rules and the requirements of Statutory Regulations and is approved for the functions stated on the Supplement attached hereto.”
In plain English: LR confirm that LOCOPIAS is suitable as loading instrument for basically all vessel types that require a CSI (Computer Loading Instrument).
We of course knew that: LOCOPIAS has been approved by many classification societies (including LR) for individual vessels, but still, we are happy that LR have now confirmed such in thus type approval. Note that LOCOPIAS was previously only certified as type 1 and type 3 software, type 2 is now added to the certificate of approval.
Actually, our previous certificate made no explicit references to these type designations, we have assumed for some time that type 2 approval was already included. The impact of this certificate is mainly that it allows more Lloyd’s Register offices to issue certificates for individual versions of LOCOPIAS and that the approval procedures should be cheaper.

Recently we have added a small but practical extention to the dragger in Fairway that you may find valuable to know about. We call it “Snap to point” and it can be used to copy the coordinates of any point in the model whenever you need to enter a position. It is used like this:
Bring up the context menu by clicking the right mouse button over the dragger. You will see a sub-menu called [Dragger], containing three options:
When a point is highlit, a dash-dotted line is drawn from the current position to where the dragger wil travel. If the dragger is not free to translate in any direction, this might not coinside with that point. This makes it possible to align a point in say, a frame, with another point in another frame, in height and breadth. This line of travel is color-coded according to its direction, using the colors associated with the main planes and axes. When the line is not parallel to any of these, then it will be colored like a curve in an oblique plane.
The coordinates displayed in the right end of the status bar normally indicate the current position of the dragger. But when snapping to other points they indicate the position that the dragger would translate to, for the currently highlit point.

Our hull modelling programme Fairway has had the ability to generate shaded surface renderings for many years, but it did not allow manipulation of the geometry simultaneously. SARC B.V. has been investing effort into the renewal of Fairway for quite some time, and one of the goals has been the visualisation of the rendered surface within the modelling interface. That goal was recently accomplished, and we are proud to provide this new functionality to our Fairway customers free of charge.
As can be seen in the screen shot below (click to enlarge) we have added a “Shell” item for every solid in the tree view, which allows the surface renderings to be switched on and off for individual solids. Sub-items show material properties that can be changed by means of a double-click. New are also the visibility checkboxes behind the group items for polycurves (“Frames”, “Waterlines” etc.) to make it easy to switch off all polycurves so just the surface is shown. Further tuning of the visualisation can be done from the Display menu, which also allows to show or hide the shell surfaces of all solids at once.
Rendering of surfaces can be a computationally intensive task. Therefore, care is taken to refresh just the parts of the shell that are affected by a particular modelling action. This is done in the background each time an action is applied, so the programme remains fully responsive and rendering needs not impede your progress; except that it is fascinating to look at these nice pictures… All cores of modern processors are involved in the task, so renderings are updated as quickly as possible.
On a side note we can also report that when surfaces are being exported to IGES format we now use the same interface to offer a visual quality check of the resulting surface patches. All in all we think these are great improvements and we wish our users happy modelling. Enjoy!

Herbert Koelman has been announced as the winner of the GL COMPIT Award 2013. The Dutch computer aided design expert was honoured for his paper’s contribution to the promotion of innovative approaches in ship design, at the COMPIT Conference which took place from 15 to 17 April in Cortona, Italy.
The jury singled out Dr Koelman, SARC, from a short list of several highly qualified candidates, because his paper outlines a roadmap for advanced ship design approaches over the next decade. His paper: “Midterm Outlook on Computer Aided Ship Design” received the highest praise for both its content and form. The jury noted that his highly readable and unpretentious paper offered a number of avenues for exploration for the industry.
Of particular note, they said was his advocation of 3D laser printing as a hands-on manifestation of 3D design approaches. His identification of underused opportunities to create numerical design series and rapid design formulas based on CFD and machine learning approaches. And above all the challenge that the paper puts to the community to avoid complacency and mental standstill and strive for innovation in methods rather than user-interface wizardry.
