Sea1 Offshore orders two more OSVs from China

Norwegian offshore vessel owner and operator Sea1 Offshore has ordered two more offshore support vessels from China’s Cosco Shipping.

In early November last year, Christen Sveaas-backed company ordered two vessels from the Chinese shipbuilder. The vessels would be based on Skipsteknisk’s ST-245 design and would be fit to serve both oil and gas and renewable markets.

The 120-m-long newbuilds will be methanol-ready and capable of running on 100% biofuel. The ships will have a cargo deck area of 1,400 sq m, accommodation capacity for 120 persons, an ROV hangar, moonpool and a 250t crane. Sea1 should take delivery of both vessels by the second quarter of 2027.

The company did reveal at the time that was in talks with the builder for potential further newbuilds and it has now confirmed an order for two additional vessels.

The vessels will be based on a similar design as the first two vessels and will have capabilities to serve both in the same markets like the first two. The scheduled delivery for the vessels is between the third and fourth quarter of 2027.
