Q5000

The Helix Q5000 DP Class 3 semisubmersible is an advanced-capabilities vessel for harsh-environment well intervention operations. The second-generation design is based on the successful Q4000 mobile offshore drilling unit (MODU). This multiservice 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 subsea construction activities.

The Q5000 features a 750-US-ton tower capable of fulfilling all traditional derrick roles, a deepwater crane with a lifting capacity to 440 US tons, and a work crane rated to 176 US tons. The open deck space supports quick and efficient loading and offloading of project supplies and equipment in a single lift.

The large moonpool enables the Q5000 to keep its intervention riser system in the water at well depth while drill pipe or other equipment is lowered to the well. This ability to keep the intervention riser system in the water while performing separate operations at the same location saves hours, thereby enhancing the vessel’s overall efficiency.
