Vattenfall has contracted Swire Blue Ocean for the installation of turbines at the Hollandse Kust Zuid wind farm. Using its Pacific Osprey wind farm installation vessel, Swire Blue Ocean will transport the various components of the approximately 140 Siemens Gamesa 11MW turbines from the preassembly site on the Dutch coast to the Hollandse Kust Zuid wind farm zone where they will then be installed.
The signing of the final contract for the installation of all turbines in the Hollandse Kust Zuid wind farm follows half a year after Vattenfall announced that it had chosen Swire Blue Ocean for the installation of the Hollandse Kust Zuid 3&4 turbines. The Pacific Osprey will have an upgraded 1,200t crane, with a boom 15 meters longer than the original, and 4,300m2 deck area. It is expected that Swire Blue Ocean will need approximately one year to complete this campaign, from loading the first turbine parts for transport to installing the last turbine. In July 2019, Vattenfall won the tender to build Hollandse Kust Zuid 3&4 following a successful bid to build Hollandse Kust Zuid 1&2. Both tenders were won with a zero subsidy bid.
