Scope and application

This standard is the DNV GL standard for the design of machinery components and structures for the complete wind turbine. The standard assumes a typical wind turbine and a design lifetime of 20 years. However, the content and the requirements stipulated in this standard can be transferred to all types of wind turbines.

Machinery components and structures for wind turbines shall be designed with the aim that:

— the maintaining of normal operational conditions will be ensured

— the safety of personnel and installations will be ensured and risks of injury to human life will be reduced to a minimum

— the machinery components and structures will reach the expected design life time

— sufficiently high reliability is reached for the entire system.

This standard covers:

— materials

— corrosion protection

— bolted connections

— machinery structures

— bearings

— blade pitching systems

— yaw systems

— mechanical brakes and locking devices

— couplings
