Altogether SEA1 will be building 4 vessels of these new designs at COSCO and all vessels will be delivered in 2027.

The vessels will be 120 meters in length, featuring a spacious open deck of 1,400 m² and accommodation for up to 120 people. They will be equipped with a 250-ton subsea crane and two integrated WROV hangars with side-launch capability. The designs are also prepared for the future installation of an offshore gangway, making them suitable for offshore wind operations.
