DONG Seeks Borssele Project Certification Services

DONG Energy has issued a call for tenders looking for certification bodies for the assessment of the site conditions at its Borssele 1 & 2 sites. The contracted party will evaluate whether a site conditions assessment has been carried out and documented adequately.

Under a 3-year contract, the contracted certification body will verify that the design basis is sufficient and adequately documented to ensure a safe design. It 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, the company awarded the tender will verify that the design of the support structures, including their bolted connection, 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.

The deadline for submission of tenders is 27 November 2017.

DONG Energy won the concession rights to build Borssele 1 & 2 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, DONG Energy and Siemens Gamesa signed an agreement for the supply and maintenance of 94 8MW turbines for the project, followed by signing of a grid connection agreement with TenneT.

The power supplied by the 752MW offshore wind farm will be sufficient to cover the annual electricity consumption of close to one million households.

Borssele 1 & 2 is scheduled for commissioning by the end of 2020.
