Offshore Wind Energy Generation System
Fixed Support Structures for Offshore Wind Turbines
01
Tower
- A structural element that supports the offshore wind turbine and transfers dynamic loads to the substructure below
- Tubular towers are mainly used
02
Substructure
- An underwater structure that transfers loads from the tower to the seabed
- Generally classified into three main types: gravity base, monopile, and jacket substructures
03
Foundation
- A structural component that anchors the substructure to the seabed
- Generally classified into two main types: gravity base foundation and pile foundation (including suction foundation)
