3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Single pile foundation
The basic type based on a single pile.
3.2 Multi-pile cap foundation
A basic type consisting of three or more piles and a cap that receives the superstructure.
3.3 Jacket pile foundation
A basic type consisting of three or more piles and steel or steel frames.
Note: It is usually divided into multi-pile single-column foundation, jacket foundation, gantry foundation and so on.
3.4 Gravity foundation
Relying on the basic self-weight and foundation resistance to resist the basic type of wind turbine load.
3.5 Negative pressure cylinder type foundation
The top-closed, open-bottomed tubular structure is the basic form of the wind turbine load that is embedded in the foundation with the wall of the cylinder.
3.6 Floating foundation
A basic form consisting of an upper float structure and a mooring system.
4 Basic regulations
4.1 The offshore wind turbine foundation has a safety rating of 1.
