Cal Dive International, Inc. proceeds with construction of the Q4000, a newbuild, ultra-deepwater multi-service vessel. The semi-submersible Q4000 will have a unique column-stabilized design that combines excellent station-keeping capability with large deck space (15,000 square feet), significant deckload capacity (4000 tons) and high transit speed (12 knots).
It will be configured to work in the deepwater depths, and in particular to carry out construction and well servicing operations in deepwater environments worldwide.
Introduction of the vessel will be in mid 2001. Working in water depths to 10,000 feet the vessel will be capable of: well completion and tree setting; template and module installation; intra-field flowline and umbilical lay; well intervention; steel pipelay (J-lay or reel-lay); life of field support, repair and maintenance; and field decommissioning. Studies indicate that the Q4000 can deliver cost savings of 15% - 20% to Cal Dive customers.
