The Ocean Basin Laboratory
Test facilities
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.
Applications
- Seakeeping
- Ship manoeuvring
- Fixed and floating structures
- Mooring systems
- Energy production from the sea
- Floating islands
- Offshore loading systems
- Offshore floating production
- Offshore marine operations
- Subsea systems and operations
- Pipelines
Ocean basin laboratory 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.
Double flap wave maker
Hydraulic driven, hinged double-flap type.
Wave characteristics:
Regular waves. Maximum wave height: 0.9 m.
Wave periods: 0.8 s and above.
Wave spectra: Computer generated or from magnetic tape.
Multiflap wave maker
Electrically driven, hinged single-flap type.
144 individually controlled flaps.
Wave characteristics:
Regular waves: Maximum wave height: 0.4 m.
Wave periods: 0.6 s and above.
Wave spectra: Computer generated shortcrested or longcrested waves of specified direction.
The carriage system follows free running models with no constraints at speed up to 5 m/s, at any heading to the waves
