58m Towing Tank

The 58 Meter Towing Tank is a cost-effective alternative for model testing to the larger tanks. With a piston type wave maker and a high efficiency matrix type beach, the 4.2m wide facility is ideally suited to small-scale tests where budget is a concern. The facility has been effectively used in the following: iceberg risk analysis, risk and reliability studies, cable hydrodynamics, resistance and added resistance in waves, and seakeeping studies.
