The 2,800-gt Bucentaur (built 1983) and the 4,800-gt Greatship Manisha (built 2010) will be deployed off the UK’s Yorkshire coast.

Worth £13m ($20.4m), the contract involves preparation work for the Hornsea Project One, which is scheduled to go into operation by 2020.

When completed, it will become the world’s first gigawatt-scale offshore wind farm and it will be able to provide electricity for more than 800,000 UK homes.
