Metocean buoy conducts tests in Dutch North Sea

NETHERLANDS: RWE Innogy and Eneco are testing a new metocean buoy to collect data on wind, current, wave and ambient conditions in the Dutch North Sea.

The buoy will be deployed for six months near RWE Innogy’s existing met mast at the 300MW Tromp Binnen wind development off north Holland, and benchmarked against it.

Tests are designed to find a cost-efficient offshore measurement solution to more expensive fixed met masts. Data recorded by the buoy will be validated against the Tromp Binnen met mast.

Independent analysts will evaluate the data and report back in the summer.

The floating device has a 2.8 metre diameter, weighs 1.7 tonnes and is equipped with a lidar (light detection and ranging) device to enable it to perform wind speed and direction measurements.

This project is co-funded by FLOW (Far and Large Offshore Wind), a research and development programme sponsored by the Dutch economic affairs ministry.

Eneco plan to deploy the metocean buoy at its 129MW Eneco Luchterduinen offshore wind farm, in the Dutch North Sea, for one year’s testing during the project’s construction.

This is the third testing and validation operation conducted at an RWE Innogy site. The other two took place at the 576MW Gwynt y Môr offshore wind farm, off Wales.
