Floating Offshore Wind Turbine Generator

Technology Roadmap Sections and Deliverables

Team 20 is to present a "level 3” roadmap of Floating Offshore Wind Turbine Generators. The following code is the identifier.

• 3FOWTG - Floating Offshore Wind Turbine Generator

Roadmap Overview

Floating Offshore Wind Turbine Generators are a technology that generates electricity by converting wind energy using turbines mounted on floating structures, which are moored to the seabed and remain stable at sea or on lakes. This technology is a form of offshore wind power, and compared to fixed systems, Floating Offshore Wind Turbine Generators can be installed in deeper waters or in coastal areas with limited space.

As the global shift toward renewable energy accelerates, wind power plays a central role. As of 2022, global wind power capacity has reached 906 GW, but the vast majority of this is onshore wind power, with offshore wind accounting for only 7.1%. Offshore wind power is divided into two types: "fixed" and "floating." This roadmap focuses on the latter, which is still in its early stages of development.

Fixed wind power involves anchoring the turbine to the seabed, usually in shallow waters up to 50 meters deep, and is a relatively mature technology. In contrast, Floating Offshore Wind Turbine Generators, which are suited for deep-water areas or countries with limited coastal space such as Japan, the U.S. West Coast, and Norway, face fewer restrictions on installation locations. However, challenges remain in terms of stability at sea, transporting electricity to land, and reducing costs. Currently, floating systems are approximately twice as expensive as fixed systems, and large-scale commercialization is expected to take time. Nevertheless, as technology advances, the adoption of Floating Offshore Wind Turbine Generators is anticipated to increase significantly in the future.
