General


This DNV GL standard provides principles, technical requirements and guidance for loads and site conditions
of wind turbines. For the first time, the requirements for onshore and bottom mounted offshore wind
turbines are defined consistently and concisely in a single document. The definition of offshore turbulence
classes has been revised significantly to include turbulence distributions adapted to the offshore
environment. In addition marine parameters have been included to define offshore type classes which may
be used for the type certification of an offshore rotor-nacelle assembly (RNA) and sub-structure.
Based on more than three decades of experience as standard setter and certification body in the wind
industry, this standard fills gaps and provides clarity and additional guidance, where existing standards lack
such guidance. The requirements of this standard focus on reaching the intended safety level in an economic
way. Where the intended safety level could have been reached in several ways, the requirements of this
standard have in general been aligned with requirements of other international standards, in particular with
the IEC 61400 series of standards.
