The Q4000 DP3 semisubmersible vessel was designed for well intervention and construction in water depths to 10,000 ft.
The Q4000 entered service in the Gulf of Mexico in 2002 and has since built one of the most extensive well intervention track records of any vessel in the world.
The Q4000 is a DP3 semisubmersible vessel purpose-built for well intervention and construction in water depths to 10,000 ft.
Because of its stable design and unique open deck, the Q4000 is an optimal platform for a wide variety of tasks, including subsea well intervention, field and well decommissioning, installation and recovery of subsea equipment, well testing and emergency well containment.
Among the Q4000’s notable features is its 600 ton multipurpose tower capable of fulfilling all traditional derrick roles, plus a deepwater crane with lifting capacities to 360 mT and a work crane rated to 160 mT.
The Q4000 also features a 38 ft x 20 ft moon pool, a 7-3/8” 10,000 psi 10,000’ rated Intervention Riser System (IRS) permanently onboard, a 10,000 ft heavy weather ROV system and an overall deck capacity of more than 4,000 mT.
The open deck plan allows for quick and efficient loading and offloading of project supplies and equipment in a single lift.Download brochure
