DNV Gl announced that it awards Siemens Gamesa Renewable Energy (SGRE) the project certificate for its Nissum Bredning offshore wind power park located in Thyborøn, in waters of north-western Denmark. The wind park consists of 4 turbines with an installed capacity of 28MW.
The park aims to new technological innovations, including a 66kV transmission system to jacket foundations with concrete transition pieces to a cable-in-pipe installation to reduce the Levelized Cost of Energy of the project.
Yet, the development of the project faced some barriers as its location at Thyborøn Kanal affected the project with sea ice during winter.
SGRE and DNV GL cooperated in detail to be sure that 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 certification was based on the Danish Executive Order No.73 (BEK 73) and covers all stages of the project development from site conditions assessment over design evaluation to commissioning.
Karsten Albers, Nissum Bredning project certification manager at Siemens Gamesa Renewable Energy commented
The use of new technologies and the environmental conditions of the project required an experienced certification approach.
Concluding, Kim Mørk, Executive Vice President Renewables Certification at DNV GL noted that the location of the wind park provided challenges for DNV GL’s experts, both from a technical and a logistical perspective.
