Siem Industries orders two subsea construction vessels 

Each vessel will be equipped with a 400-tonne active heave-compensated (AHC) subsea crane and a 50-tonne AHC subsea crane, providing significant lifting capacity for subsea construction and offshore support operations.

Designed by Sirius Design & Integration in close cooperation with Siem Industries and the shipyard, the vessels will be approximately 145 m in length with a beam of 27 m. 

The design focuses on operational flexibility and energy efficiency, enabling the vessels to support a broad range of activities across the offshore energy sectors.

In a statement, the company said, “The order represents a further commitment by Siem Industries to the subsea sector, building on our experience in the ownership and operation of specialised offshore vessels.”

Delivery of the new vessels is scheduled for 2029 and 2030.
