Vattenfall and Swire Blue Ocean have officially signed the contract for the transportation and installation of turbines in the Hollandse Kust Zuid 3&4 wind farm. The Danish operator will use their installation vessel ‘Pacific Osprey’.

Vattenfall, who won the zero-subsidy tender for the Hollandse Kust Zuid Offshore Wind Farm in July 2019, had already had pre selected Swire Blue Ocean for the transportation and installation work prior to the tender and both companies worked together to secure the bid.

Hollandse Kust Zuid 3&4 will feature 140 of Siemens Gamesa’s latest and largest direct-drive wind turbine, the SG 11.0-193 DD with a 193 m diameter rotor and an individual rated output of up to 11 MW. Swire Blue Ocean’s Pacific Osprey is one of few installation vessels capable of installing turbines of this size. To make it fit for installation the Pacific Osprey will have an upgraded 1,200t crane, with a boom 15 meters longer than the original, and 4,300 m2 deck area. Swire Blue Ocean expects that it will need approximately one year to complete this campaign, from loading the first turbine parts for transport to installing the last turbine.

Swire Blue Ocean and Vattenfall have worked together on other wind farm projects, including Horns Rev 1 and DanTysk.
