The SSCV Sleipnir, a versatile offshore construction vessel, is set to return to the East Anglia Three project in November, according to recent announcements. This return marks the next phase in the construction of one of the UK's largest offshore wind farms.

East Anglia Three, a joint venture between ScottishPower Renewables (a UK company of the Spanish renewable energy developer Iberdrola) and the UAE-based Masdar, comprises 95 Siemens Gamesa 14+ MW wind turbines. The project secured a 15-year CPI-linked Contract for Difference (CfD) through the UK government's AR4 and AR6 CfD auctions.

In July, Masdar became a co-owner of the East Anglia Three project, marking the largest offshore wind transaction of the decade, as the companies announced. This investment further solidifies the project's commitment to delivering clean energy on a grand scale.

Offshore construction at East Anglia Three began in April this year, and the SSCV Sleipnir has already made its mark on the project. The vessel completed the installation of the pin piles and jacket foundation for the East Anglia Three offshore substation in August.

The Sleipnir arrived at the East Anglia Three site on 9 August and commenced installation. The vessel's upcoming visit in November will see it install the substation topside, a crucial step towards the project's completion.

East Anglia Three is significant not only for its size but also for its potential impact. Once fully commissioned, the wind farm will deliver enough clean energy to power 1.3 million British homes, a testament to the project's ambition and the growing importance of renewable energy in the UK's energy mix.

The project has also secured a Power Purchase Agreement (PPA) with Amazon, further emphasising the global tech giant's commitment to sustainability.

The SSCV Sleipnir's work at East Anglia Three is not its first offshore substation job. The vessel recently completed a similar task at the Inch Cape wind farm site before moving to East Anglia Three.

A Notice to Mariners from 18 August states that the work has been completed, marking another milestone in the construction of East Anglia Three. As we look forward to the vessel's return in November, it's clear that the project is making steady progress towards delivering a significant contribution to the UK's renewable energy targets.
