Orwell Offshore has the capability to perform a wide variety of studies relating to vessel hydrostatics and hydrodynamics using industry standard software packages.

Using GHS hydrostatics software, Orwell Offshore is able to carry out stability studies ranging from the checking of single loading conditions for compliance with statutory stability requirements, to the production of full class approved Trim & Stability books for FPSOs.

Hydrodynamic studies are carried out using a suite of software based around Bureau Veritas’ HydroStar program. HydroStar is a three dimensional potential flow solver, which provides a complete solution to first order problems of wave diffraction and radiation. It also solves the quadratic transfer function of second order low-frequency wave loads for a floating body with or without forward speed in both deep water and in finite depth. Additionaly, it can assess the motions of multiple bodies and the effects of their interactions on motions.

Using the vessel motions output from HydroStar, Orwell Offshore is able to carry out studies on the operability and downtime of vessels in specific sea states and loading conditions, dynamic behaviour of vessels connected to mooring systems and vessels moored alongside quays or other vessels.
