Floating Offshore Wind Turbine Promotion

TODA CORPORATION

Outline

Toda Corporation was the first in Japan to install a floating offshore wind turbine in October 2013. Toda is working on expanding its use through the preparation of the "Floating Offshore Wind Pilot Farm" off the city of Goto in Nagasaki Prefecture, which was the first application of the Act of Promoting Utilization of Sea Areas in Development of Power Generation Facilities Using Maritime Renewable Energy Resources.
To take charge of Japanese main power supply, Toda provides "Anyone Anywhere As you like," a total solution that considers mass production, construction efficiency, O&M, decommission and recycling based on a solid track record.
Through these initiatives, we are striving to realize a zero-net society and early energy transition by supplying stable and inexpensive renewable energy in large quantities, and improving resilience by developing regionally distributed power sources.

Description

Japan will consume 1,200 TWh of electricity in 2050. According to a report from the IEA (International Energy Agency), Japan's floating offshore wind power has the potential of generating 9,000 TWh, 7.5 times its demand. The spread of floating offshore wind power generation is key to realizing a zero-net society.
However, the floating type is now expensive, and its use has not been widespread. Japan, on the other hand, ranks among the top three countries in the world with regard to floating technology and one of the world leaders in this area.
Therefore, Toda is working on reducing costs through mass production and improving construction efficiency, which are the keys to promoting the spread. The specific measures are as follows.

- Hybrid spar
It adopts a simple cylindrical structure using general concrete and steel. And it can be built by small ironworks and small-to-medium-sized construction companies.

- Area-saving high-speed building system
A serial production system like a factory. Mass production is possible even at small ports in the region.

- Semi-submersible vessels and multifunctional vessels
By constructing and owning two dedicated vessels for floating construction, the efficiency of on-site construction will shorten the maritime building period, and the installation cost will reduce significantly.

In this way, with the total solution of Anyone (at a local company), Anywhere (at a local port), and As You Like (to meet local needs), Toda is taking on the challenge of realizing mass production and mass installation of floating offshore wind turbines.
