As part of Equinor‘s Hywind Scotland Heavy Maintenance programme, the first of the five floating turbines (HS2) undergoing maintenance has been successfully repaired, towed back to site, and reconnected on the 15th of July 2024.
Key Details:
- Sea Impact analyzed that turbine HS2 was towed to port mid-May by three Anchor-Handling Tug Vessels and remained moored at Wergeland Group‘s Base in Norway for a total of 51 days for repairs. Satellite images showed that the unit has had the nacelle and blades down during the Port-stay.
- HS3 & HS5 are currently still moored in Port and undergoing repairs, while HS4 just arrived in Port after being towed end of last week.
- The floating project features five 6MW machines from Siemens Gamesa, mounted on spar floaters. This is the second floating project that is seeing this kind of maintenance operation, with the first being two units at Kincardine back in 2022 and 2023, which you can read more about here: Kincardine Heavy Maintenance: Tow-to-Port Approach (sea-impact.com)
