Vattenfall has reached the halfway point in the construction of the Hollandse Kust Zuid offshore wind farm in the Netherlands, which is being built 18 kilometers from the coast between The Hague and Zandvoort.
“We’re halfway towards having constructed the world’s first offshore wind farm built without subsidies; a major milestone we can all be very proud of,” says Søren Andersen, Senior WTG Installation Package Manager Hollandse Kust Zuid at Vattenfall.
When COVID restrictions were still in effect in April 2022, the crew began construction on the Cadelar Wind Osprey installation vessel.
“This meant testing procedures for each crew member, onboard quarantining and managing the logistical process within such parameters,” says Anderson. “While the strict rules and regulations were lifted for most people in the spring, the COVID protocol was maintained on the vessel until only a couple of weeks ago to prevent COVID outbreaks at sea.”
The Siemens Gamesa 11 MW wind turbines are now being deployed in a serial configuration for the first time and being made available for mass manufacture. To load the turbines aboard the vessel, careful engineering and planning are needed due to their size and weight.
“Realising such innovative and large-scale projects without subsidies is a high-level achievement in an energy industry like this,” says Andersen.
“Also, having biodiversity integrated into the design, with the creation of nature-inclusive designs, is really amazing and strengthens the motivation to deliver the project successfully,” mentions Andersen. “Creating fossil free living within one generation means generating renewable energy, while also preserving the marine ecosystem.”
