PIAS is an integrated computer program for the evaluation of a ship design. It comprises, among others, modules for hydrostatics, intact stability, grain stability, damage stability, probabilistic damage stability, and longitudinal strength, calculation of the resistance and propulsion characteristics, tonnage and deadweight, and the tank capacities of the ship. PIAS can be used in all design stages, from the first preliminary sketch up to the final design. Calculations are executed according to the different international regulations (IMO, SOLAS, MARPOL etc.).

• PIAS is a toolbox for Naval Architects.
• PIAS is a product of SARC, by a team of experienced naval architects with hands-on experience.
• PIAS is used by the vast majority of Dutch design offices and yards and many others worldwide.
• PIAS calculations are accepted by all major classification societies.
• PIAS calculations are presented in comprehensive reports.
• PIAS is fully menu-operated, thus reducing the learning curve and errors associated with software using script programming.
• PIAS modules are used beyond the scope of shipbuilding: floating transport and submersion of motorway tunnel segments, a flood barrier and offshore constructions are but a few examples.
• Continuous developments of new methods, modules and options ensure up-to-date software.
• PIAS is modular: only purchase the modules as required; additional modules can be supplied instantly.
• No annual license fees, free updates are issued.
• PIAS can deal with:
  • single, composed and asymmetric hull forms, catamarans, trimarans, semi-submersibles, and odd shapes,
  • actual COG of fluids in tanks (for heel and trim),
  • loss of cargo for open hopper vessels,
  • loss of tank contents in damage stability calculations,
  • ducted and controllable pitch propellers,
  • (damage) stability in waves,
  • user-defined and pre-defined stability criteria, etc.
