Shallow Water Basin

The depth of the Shallow Water Basin (220 x 15.75 m) is adjustable from 0 to 1.15 m. It is used to optimise the propulsion characteristics of ships as well as the (low speed) manoeuvring behaviour in shallow water. This including factors like proximity of quays and bank suction. The test can be used as input for simulations which help to optimise nautical strategies. The facility is also used for Concept Development and Design Support of new offshore designs in shallow water.

Test capabilities
  • Manoeuvring tests, zig-zag tests, stopping tests, PMM tests for determination of manoeuvring coefficients as input for the manoeuvring simulator
  • Resistance and self-propulsion tests especially for shallow water and/or narrow channels for ships and large push-tow fleets
  • Seakeeping tests with measurements of motions, wave loads and added resistance in waves for self-propelled ships
  • Behaviour of vessels in waves during beaching
  • Oscillation tests and tests in waves with a restrained model to determine hydrodynamic coefficients
  • Tests for moored and fixed objects to determine the motions, mooring forces and loads due to waves and wind
