Development of a set of software tools (macros) as part of a project to automate analysis of the numerous load cases for a special offshore vessel (Heavy lifting ship) “Pioneering Spirit”.
Pioneering Spirit (formerly “Pieter Schelte”) is a vessel with a dynamic principle of positioning. The ship designed for mounting and dismantling large offshore structures: oil and gas production platforms, elements of gas and oil pipelines etc.
Tools have been used: Femap API + MS Excel + VBA + Femap WinWrap Basic.

Macro set functionalities and features:
The dimension of the target offshore ship FEM model is about 0.5 million elements. The average speed of one “operation” (applying hydrostatic pressure to the hull elements of a ship’s hull (around 180 thousand plate elements ) is about 20 seconds.
