The CSO Deep Blue is the world's largest purpose-built ultra deepwater pipelay and subsea construction vessel. It can lay flowlines and umbilicals, and support developments in water depths ranging from 75m to 2,500m. The vessel is owned and operated by Technip Marine.

The CSO Deep Blue has an overall length of 206.5m and a moulded breadth of 32m. It has a moulded depth of 17.8m and an operating draught of from 7.5-8.95m, with a 10m maximum of draught. It has a 55,234t displacement and is 33,791gt. The upper deck aft of moonpool can withstand loading of 14lb/in². Loading for the moonpool covers is 4lb/in² and the rest of the upper deck is 7lb/in². It has a free deck area (aft of the moonpool) of approximately 7,400ft².
Pipelay

It can carry out rigid pipelay (reeling) of up to 5,500t of 4in to 18in pipe or 4,000t of 4in to 26in rigid pipelay (J-Lay). Alternatively, it can lay up to 5,764t of 2in to 16in flexible pipe. Its maximum payload of 11,023t can consist of either two rigid reels (5,511t), flexible lines in two carousels (2,000t and 1,500t), eight portable 300t reels, 4,000t rigid pipe strings or 3,000t of subsea structures.

The Skandi Vitóra joined the Technip Fleet in 2010.  She is the Group’s first Brazilian-flagged vessel and is the first Pipe-lay  vessel  ever built in Brazil.  Equipped with a vertical and horizontal pipelay system, a carousel for 2000T product, a second carousel for 750T product, two work class ROVs and a 250T active heave compensated crane she is well-suited for pipe laying, subsea construction, installation and maintenance work and can operate in water depths reaching 3,000 meters.

The North Sea Giant is amongst the largest and most advanced Offshore Construction Vessels ever built. It is a multipurpose vessel with supreme deck and crane capacity. Some of its special features is its 5 x Voith Schneider propellers, giving the vessel extremely good station keeping capabilities and low fuel consumption in DP mode. The vessel also has 3 separate engine / power systems allowing the vessel to maintain DP 3 operation with one engine room / power system out of service.

The Global 1200 is a Rigid pipe S-lay and Heavy lift  DP-2 construction vessel designed for work in both deep and shallow water. The vessel incorporates a state-of-the-art pipelay system capable of operating up to 3,000 m water depth and handling up to 60 inch concrete coated pipe. The vessel also incorporates a 1200 metric ton capacity crane suitable for conventional platform installations and a deep water lowering system also capable of operating up to 3,000 m water depth.
