Ships and offshore structures

 

​Extensive know-how and innovative solutions in
maritime technology

Our research covers maritime applications designed for open seas and arctic conditions as well as future autonomous unmanned vessels. The primary target of our research is to ensure safe, energy efficient and environmentally friendly ships, offshore structures and boats. Our customers include private industry and governmental agencies, both nationally and internationally.

We improve the hydrodynamic performance of hulls and the propulsion of ships and boats by applying CFD analysis and model testing. We develop manoeuvrability, seagoing characteristics and ship operability by using motion simulations. Our services also cover full scale verification of performance in sea trials as well as long-term monitoring of a ship's energy efficiency. Our target is also to study the ecological footprint of ship concepts by using LCA methods.

We study fluid/structure interaction, wave loads, ice loads and dynamic impacts loads in order to develop sound structural solutions for ships and offshore structures. We manage structural integrity by using structural analysis and long-term monitoring of loads. We increase passenger comfort through high-class vibration control.
