scope:

This standard is a fully updated standard for onshore and offshore wind turbine support structures and the development has been based on long experience in DNV GL with issuing standards to help the wind turbine industry in moving forward.

The new DNV GL standard for wind turbine support structures offers pragmatic design approaches and can for example be used for design of steel and concrete towers, gravity-based concrete foundations, together with steel foundations such as monopile foundations, jacket structure foundations and suction buckets foundations.

The standard contains as well requirements to materials, execution, operations and maintenance (O&M) related to the design. This is done by inclusion of guidance text, or for example by reference to material and execution standards.

Examples of new guidelines for steels structures are:

lattice towers design requirements

inspection requirements for the fabrication phase (inspection classes vs. structural member categories) with respect to fatigue-critical details when well proven track record for production exists.

Examples of new guidelines for concrete structures are:

crack control requirements

fatigue design for concrete and reinforcement with new available methods

requirements for qualification of grout material.

Examples of new guidelines for geotechnical design are:

detailed assessment of impact from dynamic loading as an alternative to gapping check for gravitybased foundations

new safety system considerations with respect to single element of failure

suction bucket design requirements

requirements for application of "observational method" for geotechnical design.
