Dutch Marine Energy Centre

The Dutch Marine Energy Centre (DMEC) has two test facilities: An inshore testing facility in one of the sluice gates in the Afsluitdijk near Den Oever, and an offshore berth in the Marsdiep between Den Helder and the Wadden island of Texel.

Our inshore test site at Den Oever is located in two ducts of the Afsluitdijk, in an existing sluice that discharges water from the IJsselmeer to the Wadden Sea twice a day. The facility is suitable to intermediate scale testing of tidal stream turbines of TRL 6-9 and enables testing in real-sea conditions in a ducted channel. Laminar flow speeds can reach up to 6 m/s and are accurately predictable. Because of its sheltered position near land, the test facility is well accessible, making installation and operation and maintenance relatively easy and cost effective. The test site has previously facilitated tests of Tocardo turbines.

The offshore Marsdiep test site is situated in open water that experiences bidirectional tidal flows of 1.0 – 2.0 m/s. The berth is close to both the harbours of Den Helder and NIOZ on the Wadden island of Texel, and is connected to the grid through an umbilical. The test site has been used previously to test the BlueTEC platform, which carried a Tocardo turbine. Tidal energy devices of all types and maturity levels can be tested here.
