Edition 2016-11 - Amended 2021-11

This standard (ST) provides principles, technical requirements and guidance for loads and site conditions of wind turbines. 

The objectives of this ST are to:

  • provide an internationally acceptable level of safety by defining minimum requirements for the determination of loads of wind turbines (in combination with referenced standards, recommended practices, etc.)
  • serve as a design basis for designers, suppliers, purchasers and authorities
  • specify requirements for wind turbines and wind farms subject to DNV certification.
This standard is applicable for the determination of design loads for onshore and bottom mounted offshore wind turbines, the relevant site conditions are also within the scope of this standard. For floating offshore wind turbines see DNV-ST-F0119. Unless stated otherwise, within this standard the term wind turbine refers to the rotor-nacelle assembly including the support structure of both onshore and offshore wind turbines. Any reference to offshore requirements is meant for offshore wind turbines only.
