Hydrodynamics for offshore applications

Numerical simulation has an important position in the offshore industry, allowing model tests to be completed. It allows many parameters to be evaluated in a very short period of time, and is also used to investigate scale effects, and complex situations that cannot easily be reproduced in model tests.

Current coefficients
Computation of forces and moments acting on a hull due to current load, in simple or complex situations such as side by side ships, shallow water or complex bathymetry, on simple or complex geometries. Vortex Induced Vibration and Vortex Induced Motion simulations...

Wave coefficients
Calculations of wave load on the hull, including all components (diffraction, radiation, viscous forces and damping) in the same formulation, including or not mooring, free motion ... These computations can be performed by the innovative SWENSE method included in ICARE solver, enabling the computation of regular, irregular, mono or multidirectional waves in an unsteady Navier-Stokes solver with a very low CPU time and a perfect description of the incoming waves...

Damping coeficients
Simulation of forced or free motion enabling the calculation of linear and quadratic damping coefficients for all motions : roll, heave, pitch ...

Slaming and green water impact
Simulations of slamming or green water impacts enabling the calculation of wave loads on ship structure...
