RWE, a German energy provider has secured offshore wind installation capacity, with the long-term chartering of two of Jan De Nul Group’s next-generation installation vessels. 

The charters are supported by a Service Agreement through which Jan De Nul Group will provide both in-house and market solutions and services, to support and perform installation campaigns for RWE’s offshore wind projects, Jan De Nul’s statement reads.

The partnership includes the exclusive and long-term charter of the two next-generation offshore installation vessels Les Alizés and Voltaire. Both can be used at RWE’s current and future offshore construction projects and, if needed, to run maintenance campaigns at its existing offshore wind farm portfolio.

Philippe Hutse, CEO of Jan De Nul Offshore Energy, “We are delighted to further step up our contribution to the worldwide energy transition through this long-term partnership. This multi-year approach creates much-desired planning security for our state-of-the-art installation vessels and will allow safe and efficient installation of a large number of offshore wind farms. We look forward to the continued cooperation with our highly valued client RWE.”

Sven Utermöhlen, CEO RWE Offshore Wind, “Europe needs more offshore wind power to reach its ambitious climate targets. We are already making a significant contribution and resolutely driving forward the future build-out of offshore wind in Europe and globally. Through this strategic partnership, RWE has taken a big step in securing the necessary installation vessels and services to deliver our large-scale offshore wind farms Thor and Hollandse Kust West VII, as well as further projects to come. These kinds of agreements are exactly what we need against the backdrop of the challenging market situation.”

Les Alizés has been chartered for more than five years, and is a purpose-built vessel designed for transporting, lifting, and installing wind turbine foundations. With the ability to lift up to 5,000 tonnes and with a deck loading capacity of 61,000 tonnes, she is capable of handling the scale and design of future foundations that will support the next generation of wind turbines.

Les Alizés’ first project will be the Danish offshore project Thor. Foundation installation works for this 1,000-megawatt wind farm are due to take place in 2025.

For both vessels, Jan De Nul has ordered a 3,500 mt monopile spreader bar from Huisman to optimise the operations and enable Jan De Nul Group to handle the largest monopiles in a safe and controlled manner.
