Ørsted has awarded DNV GL Danmark A/S with a contract to provide project certification services and evaluate whether the assessment of the site conditions at the Borssele 1 and 2 offshore wind zone has been carried out and documented adequately.
DNV GL will verify that the design basis is sufficient and adequately documented to ensure a safe design. The certification body will also evaluate that the site-specific loads and load effects are derived in conformity with the design basis, including an independent load analysis.
Furthermore, DNV GL will verify that the design of the support structures, including their bolted connections, complies with the applicable codes and standards, the design basis and the results of the ILA; and verify the interfaces between the Type Certificate, the ILA and the Support Structure Design Evaluation. All assessments will be evaluated in compliance with the IEC 61400-22.
Ørsted (formerly DONG Energy) won the concession rights to build Borssele 1 and 2 in the Dutch North Sea in July 2016. The project site is located 22km from the coast of the Dutch province of Zeeland. The wind farm will be built in water depths between 14 and 38 metres and will cover an area of 128.3km².
In July 2017, Ørsted and Siemens Gamesa signed an agreement for the supply and maintenance of 94 8MW turbines for the project, followed by the signing of a grid connection agreement with TenneT.
Borssele 1 & 2 is scheduled for commissioning by the end of 2020.
