MODU Q5000 Well Intervention Vessel Next Generation Intervention Semisub
The Helix Q5000 DP3 Well Intervention Vessel is a second-generation design based on the successful Q4000 MODU. This multi-service 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 as well as subsea construction activities.
The Q5000 features a 750 (ST) tower capable of fulfilling all traditional derrick roles, plus a deepwater crane with lifting capacity to 440 ST and a work crane rated to 176 ST. The Q5000 includes a 81-ft x 26-ft moon pool and 23-ft x 22-ft mechanized fully opening rig floor door, a 7-3⁄8 in intervention riser system, two 10,000 ft heavy-weather ROV systems and an overall VDL of 4,000 mT. The open deck space allows for quick and efficient loading and offloading of project supplies and equipment in a single lift.
The larger moon pool will allow the Q5000 to keep its intervention riser system (IRS) in the water at well depth while moving aside to let drill pipe or other equipment be lowered to the same well for another task. This ability to keep the IRS in the water while performing separate operations on the same location will save hours and enhance the vessel’s overall efficiency.
