50Hertz has launched an EUR 11.7 million call for tenders for marine warranty surveyor (MWS) services for offshore wind energy projects in both the Baltic Sea and the North Sea.
The German TSO is looking to award a framework agreement(s) for MWS services through four lots, with the contract for each lot worth a little less than EUR 3 million. The first two lots cover MWS services during installation and maritime operations on offshore converter platforms and subsea cables in the Baltic Sea, and Lots 3 and 4 concern the same work on offshore platforms and cables in the North Sea.
The framework agreement(s) will be signed for a period of four years, with two options to extend them by two years.
50Hertz’s MWS tender is open for applications until 7 November, with the start date for work awarded through the procurement set to 1 February 2026.
The TSO, part of the Elia Group, has several new projects in the Baltic Sea, including the new Ostwind grid connections, Ostwind 3 and 4, and the Bornholm Energy Island interconnection.
