UK shipbuilder Alicat has clinched an order to build the world's first hybrid offshore wind farm daughter craft.
The Great Yarmouth-based marine and engineering specialist will hand over two vessels to Scottish shipowner North Star Renewables in 2022 and 2023.
The ships will also be the first offshore wind daughter craft to be built in the UK.
The "multi-million" dollar deal was secured against stiff competition in a competitive UK-wide tender, the companies said.
