The 104-turbine, 1.6GW Nordseecluster project comprises four wind farms. Once operational in 2029, it will produce enough green electricity each year to supply 1.6 million German households.
DeepOcean has not disclosed the value of the contract, which is subject to final investment decisions by RWE.
Under the agreement, DeepOcean will take charge of the preparatory work, transport and installations of all inter-array cables, including trenching, topside pull-ins and terminations for the initial buildout phase.
In total, DeepOcean will install 185km of 66kV aluminium and copper cables, starting with Nordseecluster A’s 44 offshore wind turbines. DeepOcean will also provide installation, trenching and walk-to-work vessels to deliver the offshore work. Installation is expected in 2026.
“Awarding the contract for the initial phase with the opportunity to provide our services for Nordseecluster B will allow us to significantly reduce project execution risk,” said Øyvind Mikaelsen, chief executive of DeepOcean. “This is a risk-reducing measure that will benefit both RWE and us suppliers.”
The Nordseecluster will be constructed in two phases. The two wind farms (N-3.8 and N-3.7) of Nordseecluster A, with a combined capacity of 660MW, are currently in the permit application phase. Two further wind farms (N-3.6 and N-3.5), forming Nordseecluster B, will add 900MW of capacity.
