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.
Flume tank in Hirtshals
The core products in our flume tank are research projects and commercial testing of trawls and trawl doors. Numerous trawls have over the years been tested here, and fishermen and net manufacturers have learned to optimize the use of their gear. Also most new developments and selectivity devises have had a round in the flume tank before they went to sea, for the final tests.
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.
