DNV GL has awarded Siemens Gamesa the project certificate for its four turbine 28MW Nissum Bredning offshore wind power park in waters of north-west Denmark.
The offshore wind farm, being built in Thyboron Kanal, can be affected by sea ice during the winter months, which made the certification process particularly challenging.
The project certificate demonstrates that sea ice will have no significant impact on the lifetime of the turbines of the wind power park, despite the unique maritime conditions.
The “extraordinary location” of the Nissum Bredning offshore wind power park provided a unique challenge to DNV GL’s team of certification experts, both from a technical and a logistical perspective, according to Kim Mork, DNV GL renewables certification executive vice president.
“Having worked in close co-operation with Siemens Gamesa’s team in the past enabled us to jointly realize this project certification,” added Mork.
The certification was carried out according to the Danish Executive Order Number 73 and covers all stages of the project development, from site conditions assessment over design evaluation to commissioning.
Despite its small size the park has a specific focus on the integrating of new technological innovations, including a 66kV transmission system to jacket foundations with concrete transition pieces to a cable-in-pipe installation to reduce the project’s levelised cost of energy.
Siemens Gamesa Nissum Bredning project certification manager Karsten Albers said: “The use of new technologies and the environmental conditions of the project required an experienced certification approach."
Having worked with DNV GL on several type and project certifications in the past, we were confident that we had a qualified partner on our side with the necessary technical expertise to verify that our project operates to the highest safety and quality standards.
