Hornsea One OSS Jackets on Their Way

Spain-based Dragados Offshore has sent off all four jacket foundations for the offshore substations at Ørsted’s Hornsea Project One offshore wind farm.

The reactive compensation substation (RCS) jacket and the first OSS foundation were loaded onto Giant 6 barge at the beginning of April, and are nearing the Hornsea One site some 120km offshore Yorkshire, UK, a spokesperson from Ørsted told Offshore WIND.

According to the spokesperson, the remaining two OSS jackets were loaded onto the Castoro XI barge on 11 April and are expected to reach the offshore site in 12 to 14 days.

Dragados Offshore won a contract to fabricate and procure the foundations and their piles for the wind farm in June 2016, representing the company’s first activities in the offshore wind industry.

Hornsea Project One consists of 174 Siemens 7MW wind turbines, connected to three offshore collector substations and the RCS, the latter one located between the offshore wind farm and the shore.

The offshore collector substations transfer power from the incoming wind turbines’ medium voltage cables to high voltage, exporting it via the RCS onto the National Grid. The purpose of the RCS is to compensate for the reactive power generated in the wind farm power system.
