VIDEO: Test in our wave basin

 

Wave basin

  • +

    Specifications

    • Measurements: 14.6 m x 19.3 m x 1.5 m (length x width x depth) with an active test area of 13 x 8 m.
    • A deep water pit measuring 6.5 m x 2.0 m, with up to 6 m extra depth available.
    • Capacity: approximately 400 m3 water (400,000 liters).
    • Accommodates testing on deep and shallow water.
    • Equipped with long-stroke segmented piston wavemaker for accurate short-crested (3-dimensional) random wave generation with active absorption and pumps for currents.

    Passive wave absorber elements

    • For absorption of waves in the wave basin.
    • Built with stainless steel and hot galvanized stretch metal sheets for minimum maintenance.

    System

    System for wave and current generation

    • 13 x 1.5 m (width and height).
    • 30 individually controlled wave paddles (snake type configuration) powered by electric motors.
    • Accurate generation of 3D waves due to narrow vertically hinged paddles (0.43 m segment width).
    • Maximum wave height up to 45 cm (at 3 s period).
    • Typical maximum significant wave height in the range of 0.25-0.30 m
    • Built with stainless steel and fibreglass for minimum maintenance.
    • Pumps with a total maximum flow of 3500 m3/h for generation of strong current in the basin (up to 0.1 m/s at 0.5 m water depth). Structures can be tested in combined waves and current (following or opposing).

Wave flume

  • +

    Specifications

    • Measurements: 22.1 m x 1.5 m x 1.5 m (length x width x depth)
    • Equipped with long-stroke piston wavemaker for random wave generation and active absorption.
    • Powered by electric motors which allows for less acoustic noise, no oil pollution in the basin and more accurate waves. 

    Passive wave absorber elements

    • For absorption of waves in the wave flume.
    • Built with stainless steel and hot galvanized stretch metal sheets for minimum maintenance.
  • +

    System

    System for wave and current generation 

    • Single-element wave generator powered by electric motors.
    • Exact generation of 2D waves.
    • Maximum wave height up to 65 cm (at 3 s period).
    • Built with stainless steel and fibreglass for minimum maintenance.
    • Pumps with a total maximum flow of 1100 m3/h for generation of strong current in the flume (up to 0.4 m/s at 0.5 m water depth).
    • Structures can be tested in combined waves and current (following or opposing).

    Other equipment in the lab

    • More than 40 resistance type wave gauges including electronics
    • Large selection of pressure transducers and load cells
    • Various equipment for measurement of flow velocities (lasers, ADV, etc.)
    • Laser profiler for automatic profiling of scour holes and surfaces of rubble mound structures
    • OptiTrack Flex 13 object tracking system
    • Step gauge for run-up measurement
    • Large selection of breakwater armour units

    Water treatment system

    Our water treatment system has sand filters and reuses the water. The system has automatic refilling to specified water depth and emptying of the facilities at adjustable speeds. 

Development and sale of software

We develop software for wave generation and analysis for use in wave laboratories. Among others, we have developed AwaSys (wave generation software), which is used in more than 50 laboratories worldwide, and WaveLab (wave analysis software), which is used in more than 30 laboratories worldwide.
