ZWIJNDRECHT, Belgium – DEME Offshore has installed two of three offshore substation platforms (OSP) and 20 jackets for the Moray East wind farm in the Moray Firth in Scotland.
According to the company, it deployed a novel concept for this project. The OSP jacket and wind turbine foundation design, construction, and installation were fully aligned. Both offshore substation platforms were transported from the ENGIE yard in Hoboken, Belgium to the Port of Nigg in Scotland.
The company’s vessel Scylla installed the first topsides in early August. The second topsides has now been installed.
Jan Klaassen, Business Unit Director of DEME Offshore, said: “We are proud to have proven that combining the design, construction, and installation of the offshore substation foundations and wind turbine foundations is clearly a workable solution for the industry, especially in an EPCI contract format.
“Both foundation types were designed in a similar way and fabricated with the same companies so that we could optimize synergies such as design teams, fabrication set-up, transport and installation tools. It all worked out as planned and designed, and crucially, resulted in significant direct cost and schedule benefits for the customer.”
In total, 100 wind turbine jackets and three offshore substation jackets will be installed at what is said to be Scotland’s largest offshore wind farm.
The 950-MW wind farm is being developed by Moray Offshore Windfarm East Ltd., which is a joint venture company owned by Diamond Green Ltd. (33.4%), Ocean Winds (56.6%), and CTG (10%).
