Features of the State-of-the-Art Deepwater Offshore Basin

Reliable model testing for deep water requires the controlled modeling of wind, waves and current in time and space to achieve a realistic and well-defined offshore environment in the model basin. In the paper the development of the new state-of-the-art deepwater Offshore Basin of the Maritime Research Institute Netherlands (MARIN) is discussed as a case study in this field. The results of investigations on the current generation system and wave absorbing beaches are presented in the paper. Solutions for ultra deep water testing (water depth>1000 m/3000 ft) are also discussed. Three main solutions are available: ultra small scale testing (1:>>100), passive equivalent mooring systems or active equivalent mooring systems. The last two options are preferred and both are based on an integrated approach of model tests and numerical simulations.
