Jan De Nul secures vessel contract for Hollandse Kust West VII

RWE has signed an agreement with maritime services company Jan De Nul Group, to secure the long-term usage of two next generation installation vessels for future offshore wind foundation and turbine construction. One of them will be used for the Hollandse Kust West VII offshore wind farm.

Through these contracts RWE secures vessel capacities and services in a tight market. The partnership includes the exclusive and long-term charter of the two specialist 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 fleet.

Voltaire

“Voltaire” is the world’s largest jack-up installation vessel with a crane capacity of 3,200 tonnes
and approximately 130-metre long legs. Her innovative design makes the vessel highly suitable
for the installation of next generation wind farms in deep waters. She has been chartered to
RWE for more than four years, from 2027 onwards. Subject to the project’s final investment
decision, RWE plans to first use this vessel to install the turbines of its Hollandse Kust West VII
wind farm off the Dutch coast.

Les Alizés

“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 future-proofed by being capable of handling the scale and design of future foundations that will support the next generation of wind turbines. RWE plans to first deploy this vessel at its Danish offshore project Thor. Foundation installation works for this 1,000-megawatt wind farm are due to take place in 2025.

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.

“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.”

Philippe Hutse, CEO of Jan De Nul Offshore Energy

“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.”

Sven Utermöhlen, CEO RWE Offshore Wind

With this framework agreement, the two companies are continuing their cooperation. During
2021 and 2022, Jan De Nul Group provided installation services supporting the construction
of RWE’s offshore wind farm Kaskasi off the German coast. More recently, Jan De Nul Group
has been awarded with the export and inter-array cable installation scopes on RWE’s Thor
offshore wind farm. Source: Jan de Nul
