Coflexip Stena Offshore (CSO) Constructor on a floating drydock

The CSO Constructor is a powerful deepwater pipelay and multi-purpose subsea construction vessel capable of working throughout the year in virtually all sea, depth and weather conditions.

Built as a DSV in 1980 and successfully converted in 2001 to fulfil her deepwater multi-purpose role within the Technip-Coflexip fleet, the CSO Constructor is specially adapted to work virtually anywhere in the world, excluding Arctic areas.

The vessel offers cost-effective solutions thanks to her new capabilities and versatility; pipe installation (1500 te of rigid or 3000 te of flexible) and subsea construction with heavy lift capacity for deepwater repair and maintenance.
