Hollandse Kust Zuid wind farm progresses

Vattenfall has contracted Swire Blue Ocean for the installation of the turbines. Using its flagship Pacific Osprey wind farm installation vessel, Swire Blue Ocean will transport the various components of the approximately 140 turbines from the preassembly site on the Dutch coast to the wind farm zone where they will then be installed.

The signing of the final contract 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. Vattenfall had selected Swire Blue Ocean prior to its tender bid to build the wind farm.

“Early and close collaboration with suppliers like Swire Blue Ocean has been a deciding factor in our successful bid to build the Hollandse Kust Zuid wind farm in the Dutch sector of the North Sea,” said Catrin Jung, Vattenfall’s acting head of business unit offshore.

The Hollandse Kust Zuid wind farm zone is due to be fitted with approximately 140 units of Siemens Gamesa’s newest and largest Direct Drive offshore turbines. Pacific Osprey will transport, lift and install the turbines using its upgraded 1,200t crane, with a boom 15m longer than the original, and a 4,300m2 deck area.

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.
