The cavitation tunnel is used to investigate the hydrodynamic performance of different type of ship hulls, propulsors and other hydrodynamic objects. Propeller induced pressure fluctuations and noise as well as cavitation are investigated by means of measurements and high speed video observation. Propeller shaft and single propeller blade forces and moments can be measured using advanced in-house developed miniaturized instrumentation, in addition to standard thrust and torque measurements.
Energy and Machinery Laboratory
The laboratory is amongst the best equipped independent engine laboratories in Scandinavia. Well developed installations with highly specialized experimental equipment, instrumentation and dataacquisition systems, and an experienced staff are crucial assets in provision of professional customized support and accredited services to our clients.
Marine Cybernetics Laboratory
The Marine Cybernetics Laboratory is a wave basin, especially suited for tests of marine control systems, due to the relatively small size and advanced instrumentation package. It is also suitable for more specialized hydrodynamic tests (for example forced motion tests), mainly due to the advanced towing carriage, which has capability for precise movement of models in 6 degrees of freedom. Flow measurements can be performed using Particle Image Velocimetry (PIV) technique.
The Ocean Basin Laboratory is used for basic as well as applied research on marine structures and operations. A total environmental simulation including wind, waves and current offers a unique possibility for testing of models in realistic conditions. With a depth of 10 metres and a water surface of 50x80m the Ocean Basin Laboratory is an excellent tool for investigation of existing or future challenges within marine technology.
The main activity of the towing tanks is related to investigation of hydrodynamic performance of ships. This includes resistance, propulsion, seakeeping in head and following seas, and directional stability tests with free running models. The tanks are equipped with two carriages: One for towing up to 10 m/s for traditional calm water tests and a second carriage for seakeeping tests and other tests performed with fixed or free-running models.
