Helix Well Ops' flagship vessel, the Q4000 is a DP3 semi-submersible specifically designed for well intervention and construction in water depths to 10,000 feet. This multipurpose vessel provides a stable work platform for a wide variety of tasks, including subsea completion, decommissioning and coiled tubing deployment.
The vessel features a multi purpose tower capable of fulfilling all traditional derrick roles, plus two cranes with lifting capacities to 360 tons. Q4000 also features an 11.9 m x 6.4 m monpool, a 7-3/8" intervention riser system, a 3,000 m heavy weather ROV system and an overall deck capacity of 4,000 tons. The skid deck plan allows for quick and efficient loading and offloading of project supplies and equipment in a single lift.
Seawell Light Well Intervention / Dive Support Vessel
The Seawell has been operating throughout the North Sea and Atlantic margin as a light well intervention vessel, pioneering monohull-based subsea wireline and coiled tubing services. The Seawell's unique design and multi-service capability has significantly reduced intervention time and provided a cost effective method of maintaining subsea production systems. Seawell's track record is second to none, having entered more than 650 wells, decommissioned more than 150 live and suspended wells and 15 subsea fields.
The DP2 Seawell features a purpose-built derrick over a 7 m x 5 m moonpool and a travelling block rated to 80 Te capacity in passive mode.
Well Enhancer Light Well Intervention / Dive Support Vessel
The newest addition to the Helix Well Ops fleet, the Well Enhancer is designed to minimize production downtime and provide a cost-effective method of maintaining subsea production systems. With 1,100 m2 of main deck space and offloading capability, the new vessel can also perform a range of well testing procedures. Well Enhancer features a 150 ton multipurpose tower capable of deploying wireline, slickline and coiled tubing tools. The vessel also features kill pumps, an intervention lubricator control system and an active heave compensated main winch.
The Q5000 Well Intervention Semisubmersible is a second-generation design based on the successful Q4000 MODU. This multipurpose vessel provides a stable 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.
The vessel features a multipurpose tower capable of fulfilling all traditional derrick roles, plus a deepwater crane with lifting capacity to 360 mT and a work crane rated to 160 mT. The vessel also features a 68 ft x 26 ft moonpool and 23 ft x 22 ft mechanized fully opening rig floor door, a 7- 3/8 inch intervention riser system, two 10,000 ft heavy-weather ROV systems and an overall VDL of 3,000 mT. The open deck space allows for quick and efficient loading and offloading of project supplies and equipment in a single lift.
