The consortium behind Ossian floating offshore wind farm has awarded the contract for geotechnical investigations to two contractors: Fugro and Ocean Infinity. The Ossian project is being delivered by a partnership of Scottish renewable energy developer SSE Renewables, Japanese conglomerate Marubeni Corporation and Danish fund management company Copenhagen Infrastructure Partners (CIP).
Fugro will focus on downhole geotechnical sampling and in situ cone penetration testing, while Ocean Infinity will focus on the seabed scope which will include shallow vibro-cores and deep push seabed cone penetration tests. Fugro plans to use its purpose-built geotechnical drilling vessel, the Fugro Scout. The ship is equipped with ultra-deepwater drilling technology and onboard systems which enable the vessel to carry out marine geotechnical operations.
Meanwhile, Ocean Infinity plans to use its vessel, Stril Explorer which is a multi-purpose support vessel with seabed geotechnical equipment onboard.
Both surveys will commence this Spring. Ocean Infinity expects to have completed its survey work by the end of May while Fugro expects its downhole scope survey to be completed at the start of July.
Set to be located across 858sq km of seabed in waters off the east coast of Scotland, the project could power up to six million homes.
