MARIN does computer calculations to analyse the behaviour of ships and offshore structures. Computational Fluid Dynamics (CFD) and Numerical Fluid Dynamics now play an increasingly greater role.
We calculate the current around a vessel. A vessel has resistance to water and the higher the resistance, the more powerful the ship’s engine needs to be and the higher the fuel consumption. Computer calculations provide quite quickly a detailed view of the currents, and thus enabling us to improve the vessel design.
Vessel resistance of a ship comprises mainly wave resistance (because the vessel makes waves) and viscous resistance (because of the vessel’s wake).
We have various types of programs for calculating both types of water resistance. We can rapidly calculate and visualise the waves that a vessel makes, and analyse and improve the shape of the stern.
We carry out computer calculations for all types of structures in currents and waves, including submarines, offshore platforms, and floating wind turbines. But still model tests are required. To demonstrate that computer programs are reliable, and because we can’t yet simulate all phenomena.
To carry out many intensive calculations, MARIN has a supercomputer. This cluster of 400 calculation processors has a very large capacity that enables large, complex calculations to be done quickly. Even many such calculations can be done simultaneously.
