Updated standard for offshore wind and turbine structures

DNV’s recognized standard for design of offshore wind turbine structures has been through a revision process together with the wind energy industry. The updated standard which as per classifications society aims to reduce cost and increase safety is now available.

The standard, Design of Offshore Wind Turbine Structures, provides principles, technical requirements and guidance for design, construction and in-service inspection of offshore wind turbine structures. After its launch in 2004 it has been widely used in the offshore wind industry. This is the third revision of the standard and the updated document has been through a comprehensive peer review process involving many leading industry experts in addition to DNV’s internal quality review process.

Specific highlights include:
Section 9 for grouted connections is rewritten.
Section 11 for corrosion protection is restructured and expanded.
Section 12 for transport and installation is rewritten.
Section 13 for inspection is rewritten.
Additional publications include: Standard for Design and Manufacture of Wind Turbine Blades, Offshore and Onshore Wind Turbines, Standard for Offshore Substations for Wind Farms, Standard for Classification of Wind Turbine Installation Units,
Recommended Practice for the Use of Remote Sensing for Wind Energy Assessments, and
Guidelines for Design of Wind Turbines.
