The Dutch Ministry of Economic Affairs has launched a tender for a benthic survey of the Doordewind Wind Farm Zone.
The survey, commissioned by the Netherlands Enterprise Agency (RVO), will collect factual benthic data to verify the findings of a desktop reef detection study, the results of which are expected in July 2026, and establish a baseline of the benthic environment across the Doordewind area.
According to the contract notice published in the Official Journal of the European Union (OJEU/TED), the work will support the preparation of site data for future offshore wind farms planned within the wind farm zone.
The tender is part of the Dutch government’s offshore wind roadmap, which currently targets 23 GW of installed offshore wind capacity, according to the notice.
The contract is valued at an estimated €700,000, excluding VAT, with work scheduled to run from December 10, 2026, to December 31, 2027. The ministry has included an option to extend the contract until May 1, 2028, if unforeseen external circumstances delay completion.
Companies have until October 1, 2026, to submit bids.
The Doordewind wind farm zone, one of the three new zones designated by the Dutch Government in 2022, is located approximately 77 kilometres off the north coast of the Netherlands and will be the first zone to connect to Eemshaven. The total wind farm area is about 580 square kilometres and is planned to contain a total capacity of 4 GW divided over two sites of 2 GW each.
