With the increase in power of offshore wind turbines, the diameter of monopile foundations is increasing, and new foundations are being used: tripod and jacket. Other massive, gravity type foundations have the advantage of being competitive in shallow water, have a relatively limited environmental impact during installation phases, and can be produced locally. This context explains the interest of industrialists in the sector for massive foundations. As the French coasts are highly exposed to swell, the hydrodynamic forces on massive foundations must be studied in detail during the design phases. The design of offshore wind turbine foundations requires a large number of simulations (several thousand), so the simulation tools used must be fast enough in terms of calculation time.
