Project at a glance

In November 2020, Seaway Hawk arrived at the Port of Nigg, carrying her second load of ten jacket foundations from the UAE, for the Moray East Offshore Windfarm. This concluded a successful eight-month transportation campaign which utilised three of the company’s specialist heavy transport vessels, with Seaway Osprey, Seaway Albatross and Seaway Hawk working in rotation.

Seaway7 transported a total of 48 three-legged jackets from Lamprell’s Hamriyah fabrication yard to the Scottish installation port. The foundations averaged more than 1,000 tonnes in weight and 80m in height.

Highlights

Jacket foundations were amongst the largest in deployment for offshore wind turbine, averaging more than 1,000 tonnes in weight and 80m in height.
Each 12,000 nautical mile journey from Hamriyah to Nigg, via the Cape of Good Hope, took between 39 and 53 days.

Engineering

Stability analysis, load on/off ballast procedures and out motion analysis was carried out in parallel with the client. Seaway7 worked in collaboration with consultants to design and install deck strengthening on Seaway Hawk. OHT also designed and installed a passive anti roll tank on Hawk to make it equal to the other HTVs in sailing capacity.

‘The jacket foundations are amongst the largest in deployment for offshore wind turbines. We are immensely proud to have played a key role in delivering such a critical component for this remarkable offshore wind project.’
