Solutions for controlled wave generation

Wave movements have a significant impact on the function and lifespan of ships, offshore installations and coastal engineering. This is why scientists and engineers study these effects in hydrodynamic research labs. Their findings lead to new engineering standards and improved safety. Van Halteren Technologies will provide you with complete solutions for controlled wave generation.

Wave Generator Solutions

Typical wave generator solutions developed by Van Halteren Technologies are:

Towing carriage systems

Ship hydrodynamic research facilities are commonly equipped with a towing carriage system. The system runs on two rails which are placed on either side of a research basin or tank. The towing carriage can be operated in two different ways, it can either tow a model or follow a self-propelled model. Furthermore, the towing carriage is equipped with computers for model control and data acquisition.

Active Reflection Compensation

As an option the wave generator can be equipped with Active Reflection Compensation (ARC). With this functionality up to 90% of the height of waves traveling towards the wave generator can be absorbed. This will reduce the amount of re-reflection and hence improve the quality of the generated wave.

With ARC the maximum test duration can be increased, while the effect of unwanted low frequency oscillations is decreased. Another interesting aspect of ARC is that the time between tests can be decreased by effectively stretching the water surface.

Hydrodynamic research solutions

Other important hydrodynamic research solutions offered by Van Halteren Technologies are:

  • Drive and fixation systems for adjustable floors
  • Adjustable platforms for wave generators for variable hinge depth
  • Stowage systems for lifting the wave generators out of the basin
  • Planar motion mechanisms
  • Passive wave absorbers
  • Refurbishment of existing equipment

Drives and controls

In consultation with the customer Van Halteren Technologies translates the application procedures into a control philosophy, which forms the basis for the development of hardware and software. The specially designed controls with dedicated software enables the operator to go through different phases of the procedures fully controlled. The integrated control system provides the operational capability to the system and continuously guards the system safety. To assure the safety and reliability of the integral system extensive redundancy features are included in the drive and the control technology.


Data retrievement

The control system is based on a master-slave principle and controls the correct interaction between the central computer and the modules. The provision of actual data of the drive & control system enable manual interventions by the operator. Apart from the functional control the operator control panel provides a Graphical User Interface, facilitating system monitoring and parameter adjustment.
