Dutch RVO and EnBW issue Doordewind offshore wind contract notices

Contract notices for services for the development of offshore wind farms in the Doordewind wind farm zone and in the German Exclusive Economic Zone (EEZ) have been published by the Dutch Enterprise Agency (RVO) and German EnBW.

By the end of May or the beginning of June 2023, RVO plans to release a tender. The tender’s objective is to reach agreements with one or more bidders who are qualified to conduct geophysical studies at the Doordewind wind farm zone.

The tender will be broken into three different lots based on the scope and type of data. While the precise parameters of the assignment will soon be defined, separate lots of both 2D and 3D Ultra-High Resolution Seismic (UHRS) surveys are planned.

Beginning in 2024 is when the offshore campaigns for the investigations are expected to commence. The auction for the 2 GW Doordewind I and 2 GW Doordewind II will take place in 2027, with the ships’ commissioning scheduled for 2031.

EnBW scope

EnBW issued a contract notice for geology, oceanography, and hydrology services. In order to establish new offshore wind farms in the German Exclusive Economic Zone, EnBW plans to conduct a geophysical survey.

Multibeam Echosounder (MBES), Side Scan Sonar (SSS), Gradiometer, Subbottom Profiler (SBP), and optionally 2D UHRS will all be used in the study. Without including VAT, the anticipated total contract value is €10 million. According to the notice, the contract would last for ten months with no chance of renewal.

A contract notice for environmental surveys and impact analyses, such as benthic and fish surveys, marine mammal surveys, and bird surveys in the German EEZ, was also published by EnBW. There are three lots in the deal. The deadline for receiving tenderers or participation requests is May 8.

Beginning no later than February 2024, the offshore surveys will be undertaken continually for 24 months. According to the notice, the final report must be presented no later than May 2026 and the interim report must be submitted no later than May 2025 after a year.
