Updated PIAS Layout file format

Posted on May 18, 2017

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.

Article Naval Architect April 2017

Posted on April 20, 2017

In the April 2017 issue of the Naval Architect journal, an article has been published about recent developments in PIAS. Discussed subjects are:

  • The recent restructuring of the PIAS program suit. PIAS used to contain quite some separate modules, from which many have merged into core functional modules for e.g. hullform design, compartment modelling, intact and deterministic damage stability and probabilistic damage stability. Presently under construction is a local cloud which enables data sharing between the PIAS modules.
  • Conventional data exchange, such as file export to CFD, IGES and the Poseidon scantling program from DNV.GL.
  • Non-conventional data exchange, notable the collaborative design and engineering platform as currently under development in collaboration with CADMATIC.
  • Modelling of geometry of pipe lines in PIAS, and its use in design evaluation (such as probabilistic damage stability) and engineering.

Announcement SARC user day on 7 April 2017

Posted on January 11, 2017

We are happy to announce that the SARC user day has been scheduled for 7 April 2017. So please save this date! Throughout the day there will be several presentations on the developments of PIAS and LOCOPIAS over the last few years and we will give you an idea of our plans for the following years. To get a small impression of the latest developments, check our recent newsletter or see other publications in the news section .

During the day, there will be plenty of opportunity to meet us and your fellows.

The preliminary program is stated below. An official invitation with the final program will be sent to you at the end of February.


SARC day on 7 April 2017:

09:30 – 10:00  :           Receipt

10:00 – 17:00  :           Several presentations, lunch and short breaks

Probabilistic damage stability: enhanced algorithm for the determination of damage case dimensions

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:

  • To accommodate damages over centerline (as already announced in the newsletter of October 2015).
  • To be able to handle non-foursided compartment shapes. With PIAS’ old compartment definition module Compart all subcompartments were limited to four sides. Newlay, the replacement module of Compart, supports a wider variety of shapes, including subcompartments having from three to twelve sides. Because all damage stability modules are being prepared to support this extended definition, the Probdam damage case management library must be updated accordingly.


The update of this algorithm has three consequences:

  • The found extent of damage can be slightly different than with the previous algorithm. By the way, the manual contains a short elucidation on the process of finding the damage boundaries.
  • Not each and every damage case is indeed possible, given the rules and constraints of SOLAS2009. This new algorithm has been further optimized to find matching damage boundaries, where with the previous algorithm it could have been concluded that the damage was impossible.
  • Although finding the extent of damage may be a time-consuming process, the old algorithm was highly optimized to do it as swift as possible. The new algorithm has to evaluate more complex cases – over CL, and non-foursided – which inevitably will result in occasionally longer processing times. However, please be assured that SARC has used every option to keep the performance high. In this respect contemporary computer hardware facilities can also be employed, with PIAS’ octothreading speed enhancer, which is scheduled to be released within some weeks.

A version of PIAS’ Probdam with this enhanced algorithm will be available for download from September 6, 2016.

Revised freeboard module from PIAS

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.
