Concept Basin

The MARIN Concept Basin has a length of 220 m, a width of 4 m and a depth of 3.6 m. The basin is filled with fresh water. The basin is mainly designed to perform calm water and seakeeping model tests of ships and structures in the concept phase. Furthermore, the basin can be used for research purposes.

Carriage
The basin has a stiff overhead carriage which runs over the full length of the basin. The maximum speed is 10 m/s.The carriage can be fitted with a large stroke vertical (VIV) oscillator to test vortex induced vibrations on pipes, risers and other slender constructions. Maximum Reynolds number up to 5E5.


Waves and wind
A wave generator is fitted at the end of the basin. The wave generator consists of 8 hinged flaps. Each flap (with a width of 50 cm) has its own driving motor, which is controlled separately. The capacity of the wave generator is up to a significant wave height of 0.55 m at a peak period of 2.3 seconds. Regular wave capacity is 1.1 m at a peak period of 2.3 seconds. Opposite the wave generator, a passive sinkable wave absorber is installed. The wave generator is equipped with compensation of wave reflections form (ARC) the model and the wave absorbing beach. Wave generation is based on higher order wave synthesis techniques.

Wind can be simulated by an adjustable platform spanning the full width of the basin fitted with electrical fans.

Test capabilities
  • Resistance and self-propulsion tests in calm water and in waves
  • Seakeeping tests (in head and following waves, and other wave directions at zero speed)
  • Captive tests in calm water or waves (e.g. curent loads, manoeuvring coefficients)
  • Installation and sea transport tests of offshore structures
  • Tests on moored and fixed objects to determine motions and loads due to waves and winds
  • Wave energy tests (renewable energy devices)
  • VIV (vortex induced vibrations)
  • Drop tests for freefall life boats
Model size range
  • Model length of 1 – 4 m
  • Floating structures of any kind, size depending on water depth
  • Length for VIV oscillator 3.4 m
