Do It - catching waves at 30 knots!

Waves don’t give way. Fast, small boats in a limiting sea state can be surprised by a steep crest or deep wave trough, and a crew transfer to a wind turbine can become a nightmare by an unexpected wave group. Speed is often reduced as a precaution or operations are cancelled altogether to avoid injury, motion induced illness and damage.

The Do It project aims to increase the operability of small boat operations by the forward prediction of vessel motions using radar remote sensing of the waves. The project was done in a cooperation between Radac, Damen Shipyards, Next Ocean, the Royal Netherlands Sea Rescue Organisation KNRM and MARIN.

Radac and applied physics lab TNO succeeded with the development of an innovative and compact solid-state phased array FMCW radar which was able to catch the essential wave data. It scans wave orbital velocities over 400 metres in a 90-degree segment. A wave inversion model based on recent projects ‘Salute’ and ‘Promised’ carried out by MARIN and NextOcean integrates the velocities into a wave system, which is used by a ship motion simulation tool developed by MARIN
