Ocean basin

illistrasjonsbilde

The ocean basin laboratory is used for studying basic as well as applied ship and offshore problems. A total environmental simulation including wind, waves and current offers unique testing conditions for models of all types of fixed and floating structures. A water depth of 10 metres offers excellent testing possibilities for deep water structures intended for the offshore industry in future. The ocean basin is operated by MARINTEK , but NTNU has access to the facility through a co-operation agreement.

Data

  • Length: 80 m
  • Width: 50 m
  • Depth: 0-10 m Maximum current velocity approx. 0.2 m/s at 5 m water depth.
  • Down at 7.5 m water depth maximum current velocity is approx. 0.15 m/s.

The carriage system follows free running models with no constraints at speed up to 5 m/s, at any heading to the waves.
