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 SINTEF Ocean, 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.
