The transport and installation of Ørsted’s 242 MW Gode Wind 3 and 900 MW Borkum Riffgrund 3 offshore wind farms in Germany has started. The first batch of three monopile foundations has left Steelwind’s yard in Nordenham, Germany to Eemshaven, in the Netherlands, which is part of Groningen Seaports.

Under its contract, jan De Nul Group will transport and install 106 wind turbine monopile foundations and one offshore substation foundation, including the associated topside.

Wagenborg scores logistics job

Jan De Nul has contracted Wagenborg as the logistics supplier for the job. Wagenborg deployed its Wagenborg Barge 8 for the first transport of the monopiles foundations from Steelwind’s yard in Germany to marshalling harbour Eemshaven in the Netherlands.

In the upcoming months, Wagenborg will perform another 35 voyages with monopiles from Germany and Denmark to the temporary storage in Eemshaven using Wagenborg Barge 8. The pontoon is equipped with hydraulically operated saddles and an additional internal ballast system to carry three monopiles per voyage. Wagenborg’s engineers carried out detailed calculations for this method of transport, taking stability, sea conditions and a weight of 1,500 ton per monopile into account.

In Summer, Jan De Nul’s heavy lift vessel Les Alizés will arrive on site and install the first monopile foundation offshore, simultaneously the baptism of fire for this brand-new vessel.

The first job for Les Alizés

Les Alizés was delivered by the CMHI Shipyard in China in January and is currently sailing to Eemshaven in The Netherlands. This vessel investment is a response to the global trend within the offshore wind energy sector to design and install increasingly larger wind turbines.

Thanks to its dimensions and lifting and loading capacities, Les Alizés will be able to load out, transport and install multiple units of the largest and heaviest wind turbine foundations. In addition, it will be able to install heavier and larger foundations into deeper waters and in more challenging seabed conditions. It will mainly be used for the construction of offshore wind farms, but it is also extremely suitable for decommissioning offshore oil and gas platforms.

Work scope set for completion in 2024

Both wind farms will use 11-MW Siemens Gamesa turbines and are located in the German North Sea. The Borkum Riffgrund 3 more particularly will be located adjacent to Ørsted’s existing offshore wind farms Borkum Riffgrund 1 and Borkum Riffgrund 2. Gode Wind 3 will be close to Ørsted’s Gode Wind 1 and 2.

For the first time, Ørsted will be using monopiles with secondary steel components instead of a transition piece for connecting turbine and foundation.

Delivery is foreseen to be completed in 2024. Once in full operation in 2024 and 2025, respectively, these wind farms will generate enough electricity to power approx. 1.2 million German households every year.
