Ship design and hydrostatics / stability package, ShipShape

ShipShape is ideal for a wide range of situations where fast and flexible reconfiguration of the vessel model is needed or the way of calculation must be changed.

Imagine for instance a grounding incident: The Salvage Master is faced with a vessel that has sustained severe damages to the foreship: Will the vessel float when pulled off the shoal, how will its floating position be, what measures should be taken to minimise stresses and prevent her from breaking up?

Or perhaps you are the ship designer that is requested by an Owner to prepare stability calculations and documentation for Marine Authority or Class approval for his vessel. There is no computer model available from any Yard, so you need to prepare all the geometry files from scratch based on drawings and prior documentation.

In both the situations outlined above, the ShipShape Ship Design program will provide answers and results to the user within a minimum amount of time. ShipShape comprises all modules and functions required for vessel geometry modelling (and remodelling), intact and damage stability calculations, tonnage, load line, loading conditions, and more. The program is ideal for early design / feasibility studies where its parametric design features will enable swift changes in the vessel configuration and allow for the proper evaluation of the relevant design alternatives.

True interactivity and integration

With ShipShape, there are no batch files, no jumping in and out of programs and processors to arrange files, and no external modules or programs to be run: It is all contained within the same executable and well hidden away behind the scenes.

Intuitive and authoritative

The ShipShape system was initially developed as an in-house tool for R&D and Educational use at the Norwegian Institute of Technology / Norwegian Maritime Technology Research Institute (Marintek) in Trondheim, Norway. This high-tech heritage has had a major bearing on the system ever since, with the continuous addition of new features and advanced functions. This includes special functions for offshore vessels, barge grounding / submersion calculations, fishing vessels, and more – obviously in addition to all the "standard" functions you would expect to find.

Today, the ShipShape system is popular with students and educational institutions due to the intuitive use and configuration, as well as the powerful and flexible functions that will cater for even the whims of the creative designer… or a student.

Basis tool for onboard solutions

Another feature of ShipShape is that it is the shore-based counterpart to ShipLoad and Lodic – the onboard Loading Instrument (LI) or Loading Computer for ships and offshore rigs respectively. This means that all vessels with a ShipLoad LI will have a corresponding database that can be manipulated and tweaked ashore for instance to evaluate special projects or conversion purposes. Furthermore, the ShipShape  Emergency Response capabilities will allow shore staff to assist and provide advice to the Vessel in case of an incident or emergency.
