Idemitsu Kosan Co., Ltd. announced that its subsidiary, Idemitsu Snorre Oil Development Co., Ltd. has submitted a development plan of supplying power from floating offshore wind to the Snorre field through Idemitsu Petroleum Norge AS. Idemitsu aims to start supplying power from offshore wind in late 2022, following the assembly of floating wind turbines at Gulen Industrihamn in western Norway and transportation to the site in the Norwegian North Sea.
The selected concept for the project is to build an offshore wind farm called “Hywind Tampen floating wind farm” consisting of the 8MW x 11 wind turbines (Total 88MW). This will be located some 200 kilometres north west of Bergen in west Norway and supply the offshore oil and gas platforms with power. This could be the first time an offshore wind farm is directly connected to oil and gas platforms. The power from the wind turbines would be supplied to the Snorre field, of which the company owns a 9.6% interest through Idemitsu Petroleum Norge AS, and also to the nearby Gullfaks field. Equinor’s “Hywind” concept has been selected as the floating offshore wind technology for the project, and Norwegian authorities through Enova have made a funding commitment for part of its development cost.
By reducing the use of gas turbines on the Snorre and Gullfaks fields, the entire project helps cut CO2 emissions by more than 200,000 tonnes per year, approximately 35% of the power demand of the platforms.
