Herbert Koelman appointed Lector of Maritime Innovative Technologies at MIWB

Posted on May 8, 2018

Herbert Koelman, who founded SARC in 1980, has recently been appointed as Lector Maritime Innovative Technologies at the Maritime Institute Willem Barentsz (MIWB). The function of a Lector is initiating and managing applied research, as well as supporting education. This appointment is for two days a week, the other three days Koelman will remain at SARC, in software development and general management.

MIWB is an academy within NHL Stenden University of Applied Sciences, and offers BSc and MSc educations in the design and operations of ships. The research objectives of the Maritime Innovative Technologies research group are in the field of innovation in the field of maritime operations, design and production, and in particular the relationship between these three. One of the first projects envisaged will be to convert measured operational (big) data into design tools for ship design. For more information on this subject you can contact Herbert.Koelman@NHL.nl.

LOCOPIAS IMDG implementation

Posted on April 19, 2018

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.

Jan de Nul attends a probabilistic damage stability training

Posted on April 16, 2018

Last week our colleagues provided a probabilistic damage stability training in Aalst, Belgium, the home base of Jan de Nul, a leading and maritime construction company. To know more about the trainings we provide, please check the ‘Training’ page.

Verification of LOCOPIAS for EBIS

Posted on February 6, 2018

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.

The manual is in English and Dutch.

Hopper stability integrated into PIAS’ Loading module

Posted on February 6, 2018

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.

Lloyd's Register Type Approval LOCOPIAS extended

Posted on January 25, 2018

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.

Update of stability criteria in PIAS

Posted on January 10, 2018

A number of standard stability requirements have been programmed, an overview is presented in the figures below.

Second generation intact stability criteria scan

Posted on November 14, 2017

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.

To make sure this won’t happen

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:

  • Parametric roll, first level, and second level (C1 factor only).
  • Pure loss of stability, level one and two (however, the latter without the relaxation of wave height up to the highest 3%).
  • Surfriding and broaching, first level.
  • Dead ship stability, first level.
  • Excessive acceleration, first level.

The deliverable will be a report with results and conclusions.

Symposium on Chinese and Dutch Yacht building processes

Posted on November 6, 2017

Last month the RYDC organized a bilateral talk on Dutch and Chinese Yacht Engineering Technology and Cooperation on October 26th in Seven Star Bay, Shenzhen. At this symposium the following companies gave a speech (from left to right):

  • SARC (Herbert Koelman)
  • University of Delft (Jenny Coenen)
  • University of Twente (Robert Wendrich)
  • University of Wuhan (Prof. Cai Wei)
  • Mastership (Jacques Hoffmans)
  • Hey Sea (Allen Leng)
  • Moana Yachts (Chris Wang)

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.

Modified computation method for ullage & sounding under heel or trim

Posted on October 4, 2017

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.
