During operations, which are due to start shortly, Jumbo will deliver the transition pieces from the marshalling yard to the offshore site. It previously worked with Van Oord on the Arkona offshore wind farm, also in the Baltic.
Jan de Nul has contracted the Jumbo-SAL-Alliance to install secondary steel structures at Ørsted’s Gode Wind 3 and Borkum Riffgrund 3 offshore wind farms.
The MV Lone completed mobilization in mid-July and has now started the execution phase. In Emden the vessel was fitted with a fly-jib, additional living quarters and client-provided project equipment.
A new tugger arm arrangement at crane 2 should improve offshore operations, Jumbo said.
The vessel then sailed to Italy to collect further equipment for the project on Jan De Nul’s behalf, then up to Eemshaven for the first load-out of secondary steel components for installation at Gode Wind 3 and Borkum Riffgrund 3, with a combined capacity of 1,166 MW.
These will be powered by 11-MW Siemens Gamesa turbines.
The two wind farms should be operational by 2024 and 2025. Les Alizés is already installing the 107 monopile foundations, including one for the offshore substation.
MV Lone’s scope relates to installing boat landings, platforms and corrosion protection systems on the foundations.
