According to Sren Andersen, Senior WTG Installation Package Manager Hollandse Kust Zuid at Vattenfall, “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.” This statement was made in reference to the construction of the world’s first offshore wind farm built without subsidies. When you speak with Sren Andersen, you get a true understanding of what it means to be constructing what will be the largest subsidy-free offshore wind farm once it is operational. It’s a job that never stops. The installation vessel Wind Osprey owned by Cadeler, which transports the turbine blades to their final destination in a later step.
When the crew that will eventually work on the Cadelar Wind Osprey installation vessel began their work in April 2022, COVID regulations were still in effect. “This required testing protocols for each crew member, onboard quarantining, and managing the logistical process within such constraints,” explains Anderson. “All of these things had to be accomplished within these parameters.” “Although the stringent rules and regulations were relaxed for the majority of people in the spring, the COVID protocol was upheld on the vessel right up to a couple of weeks ago in order to prevent COVID breakouts at sea,” The vessel makes complete circuits, each of which is powered by four turbines. The expeditions might take anywhere from five to twelve days to complete, depending on the circumstances of the weather. While on board, the crew rotates between working two weeks on and two weeks off, each of which consists of two 12-hour stints. Because of the unfavorable weather conditions, the crew may have a delay when transferring off the vessel, which will ultimately result in a delay in returning home. The spirits of the team are likely to take a hit as a result of this. According to Andersen, “the installation team deserves a lot of respect for continuing to stay on course and delivering the work, notwithstanding the hurdles they may confront.”
The act of delivering the work in and of itself is not a typical or normal process. The Siemens Gamesa 11 MW wind turbines are being deployed in a serial configuration for the very first time, and they are also being made available for commercial manufacture. Because of their size and weight, the turbines cannot be loaded aboard the vessel without first undergoing extensive engineering and planning. According to Andersen, “Realizing such cutting-edge and large-scale projects without the assistance of subsidies is a high-level success in an energy industry such as this. 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. “Also, having nature-inclusive designs strengthens the motivation to deliver the project successfully.” Producing renewable energy while also protecting the marine ecology is necessary to meet the goal of transitioning away from the use of fossil fuels within one generation.
