a time domain simulation program for study of motions and station keeping of multibody systems.

Flexible modelling of station keeping forces and connecting force mechanisms (anchor lines, ropes, thrusters, fenders, bumpers, docking guide piles) is included. The results from the program are presented as time traces, statistics and spectral analysis of all forces and motions of all bodies in the analysed system.

Simo is a modular and interactive computer program with batch processing options, and is also available as part of Sesam’s DeepC package for coupled analysis of floating vessels including station keeping systems.

Typical applications:

Surface Vessels

• Mono-hull vessels
• Semi-submersibles
• Tension leg platforms (TLP)

SPAR-buoys

• Positioning
• Turret mooring
• Spread mooring
• Dynamic positioning
• Tension Legs

Complex Marine Operations

• Offloading (tankers in tandem or side-by-side)
• Offshore crane operations
• Subsea installation (e.g. subsea templates)
• Jacket / deck installation and removal (floatover)
• Installation of TLP and GBS by e.g. tugs
• Up-ending of SPAR
