The Ossian project of up to 3.6 GW has become the first ScotWind floating offshore wind farm to finish key geotechnical surveys, according to an announcement on Wednesday.
Located 84 km (52 miles) off the east coast of Scotland, in water depth of around 72 m (236 ft), the project is a joint venture between SSE Renewables, Japan’s Marubeni Corp (TYO:8002) and Copenhagen Infrastructure Partners (CIP).
The geotechnical surveys, which have been in progress since spring, have provided essential data for the installation design and a better comprehension of the seabed environment. The work was carried out by contractors Fugro and Ocean Infinity.
“We are the first large scale floating offshore wind farm to reach this milestone and are pleased with the progress that’s been made,” senior project manager David Willson. Together with other ScotWind developers, Ossian also recently completed a two-year digital aerial bird survey across the North Sea, Willson added.
According to the announcement, Ocean Infinity’s scope included shallow vibro-cores and deep push seabed cone penetration tests, some of which were performed remotely in an industry first.
Fugro carried out downhole geotechnical sampling and in situ cone penetration testing.
