Award of contract for development of high voltage dynamic export submarine cable for floating offshore wind power plants

June 4, 2019

We have been awarded the contract by the Carbon Trust of the United Kingdom for design, initial testing and development of a high voltage dynamic export submarine cable.

This development project is part of the Carbon Trust’s Floating Wind Jointing Industry Project (Floating Wind JIP) dynamic export submarine cable competition. The Floating Wind JIP is a R&D collaboration between twelve offshore wind developers EnBW, ENGIE, Eolfi, E.ON, Equinor, innogy, Kyuden Mirai Energy, Ørsted, ScottishPower Renewables, Shell, Vattenfall, Wpd, with support from the Scottish Government. Under the contract, we are developing a 130kV to 250kV high voltage dynamic export submarine cable to enable power transmission from an offshore floating substation to shore, which was identified as a bottleneck for future commercial floating offshore wind power plants.


In 2013, we developed and supplied the world's first 66kV dynamic submarine cable for the Fukushima floating offshore wind farm demonstration project (“Fukushima FORWARD”), funded by the Ministry of Economy, Trade and Industry. Our company's proposal of technology and processes verifies the dynamic cable product design demonstrated by Fukushima FORWARD was highly regarded, leading to this contract.

The practical application of floating offshore wind power plants is more favored in Japan, surrounded by deep sea areas with good wind conditions. We aim to further contribute in the field of renewable energy by developing higher voltage dynamic submarine cables utilizing the technologies we have cultivated.


Our company will contribute to growth of deployment of wind power plants in the power sector, as well as a shift towards the Energy Mix in the future - promotion of energy efficiency and conservation, and introduction of renewable sources of energy. Our company aims to become the main player in Asia in the extra-high voltage cable field.

(note 1)Dynamic submarine cable is a submarine power cable which floats in the sea and dynamically follows the movements of the floating equipment such as offshore floating high voltage substation, wave, and tide.
