Integration sounding in Loading

Posted on December 30, 2022

For many years, PIAS has  a module Sounding, which computes  tank capacities and corresponding COG for an arbitrary list/trim combination, if applicable also with temperature correction to account for expansion of tank structure or cargo. The latter also with support for standards, e.g. ASTM tables for liquid hydrocarbons. These results can be utilized in a […]

Definition of multiple damage boxes

Posted on December 26, 2022

For damage cases it is possible to use a so-called damage box, interactively a rectangle can be dragged, which makes the contained compartments flooded. This is a quick and consistent tool for declaring a large number of compartments flooded simultaneously. Now there is the possibility to define multiple damage boxes that can be quickly switched.

Ice belt as draft mark

Posted on December 26, 2022

At draft marks the user can define minimum and maximum drafts for sailing in ice. This defines a so-called ‘ice belt’, which is graphically drawn and also checked. The user can turn the ice belt on and off in the settings of a loading condition.  

Envelope curve longitudinal strength

Posted on December 22, 2022

There is also the option to calculate and output the so-called ‘Envelope curve’. With this option, the envelope upper and lower limits are calculated of the occurring shear forces and moments based on the curves of the selected loading conditions. This envelope curve can be used to determine how strong the ship should be at […]

On user request, the module “Cargo Weight” in LOCOPIAS  Draft survey – SARC is extended with functionality to read the (draft)sensors.

After the sensor reading the […]

Minimum allowable G’M

Posted on November 3, 2022

At the stability criteria it is possible to enter a table of minimum allowable G’M, for example calculated with the probabilistic damage stability : In the summary of the stability criteria in Loading, this minimum allowable G’M was printed as a maximum allowable VCG’. From now on, it is printed as a minimum G’M, see […]

In the menu with the overview of loading conditions, under the ‘Output / Damage stability’ option, there is a new additional option ‘Longitudinal strength’ : If this option is selected, longitudinal strength calculations are made for all selected loading conditions for damage stability (2nd column in this menu) and for all selected damage cases for […]

Constraint management in PIAS Layout

Posted on August 9, 2022

SARC has developed a constraingt management feature for our Layout module. Constraint management is an important step in automating a part of the design proces, while leaving the designer firmly in the captain’s seat. When the Constraint Management program is used, a feasible ship compartment design can be made in a quick manner and the […]

During the design process, compartment geometry or tank properties are frequently changed in order to optimize the performance of the design. Changes in tank geometry (and hence in volume etc.) are always processed in subsequent modules (In Loading immediately if ‘direct calculation of tank data’ has been switched on, see However, for some tank […]

The strip theory method of PIAS’ Motions has been expanded with the option to include additional roll damping. The implementation is based on el Moctar, B. O., Schellin, T. E., & Söding, H. (2021).

Appendage points visible again in PIAS

Posted on August 10, 2021

Vessels are always equipped with an appendage in PIAS. At the starting point ‘Start appendage’ appears on the right. The appendage points are shown in grey and cannot be changed. Nor can points be deleted or inserted. It is only meant to confirm the location of the appendage points. More info at:

In the program for reporting an inclination test, a VCG is determined per measurement, so that all small hydrostatic differences that may arise between the measurements are fully taken into account. Such may for example be differences in KM — because PIAS determines rather accurately for each heel the hull intersection with the waterline, and […]

Computations of PIAS often involve many steps, however, (paper) space and human attention span are too limited to present each and every intermediate computation sub result. So, only the most prominent results are printed — or listed, or exported, for that matter — and the experience over the past decades has shown that the standard […]

Direct calculations of tank data

Posted on July 14, 2020

Until now, the tank data from the weight list of a loading condition were interpolated on a pre-calculated tank table. This required tank tables to be calculated in the Layout module. In this implementation, the accuracy of the interpolated data was dependent on the step size of the computation of the table. Recently, in PIAS […]

PIAS ES 3: Vigintithreading

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 […]

Stability criteria with PIAS

Posted on June 19, 2018

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 […]

Surface export from PIAS/Fairway

Posted on May 15, 2018

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 […]

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: Portside (PS). Starboard (SB). The side of the statical angle of inclination. With this setting, the side of the worst stability is estimated with this method: if this statical angle is […]

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 […]

Acceleration of PIAS

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 […]

SARC says farewell to Windows XP

Posted on January 12, 2016

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 […]

For many years, the hullform modeller of PIAS, Fairway, has a capacity to import the hull shape from files in (several formats of) IGES or DXF format. We noticed a rising application of trimmed surfaces in IGES, for that reason the Fairway import now also supports this IGES sub format.
