SCT - Major Floating Wind Farm Offshore Scotland to Power Oil and Gas Field

Flotation Energy Plc and CNOOC Petroleum Europe Ltd have submitted an Offshore Scoping Report for a floating wind farm offshore Scotland with a capacity of up to 480 MW and scheduled to be operational by 2026.

The Green Volt offshore wind farm would feature up to 30 wind turbines with a rated capacity of between 10 MW and 16 MW and up to two fixed-bottom offshore substations which would deliver the electricity to both the Scottish grid and the Buzzard oil and gas field where CNOOC is the operator and the largest shareholder.

This would enable the removal of the offshore power station, which currently fuels oil and gas production
from the field. This decarbonisation project would be the first of its kind in the UK.

The Green Volt offshore wind farm would be developed on a brownfield site previously hosting the Ettrick and Blackbird oil field, 75 kilometres east of the Aberdeenshire coast, where large amounts of site data already exists.

Green Volt aims to utilise this data to streamline the Environmental Impact Assessment (EIA), Habitats Regulations Appraisal (HRA), and other associated consent submissions of the proposed wind farm.

One export cable would supply the Buzzard oil field 15 kilometres away, whilst a second export cable would supply the National Grid, making landfall near Peterhead.

A turbine manufacturer has not been confirmed to date, and the project expects to consider proposals from Siemens Gamesa, GE, and Vestas, the developer said.

The turbines will be installed in water depths of between 100 metres and 115 metres and harness average wind speeds of 10.93 m/s with an expected capacity factor of 55 per cent, the developer said.
