The Helix Q7000 DP3 semisubmersible performs through-riser well intervention and decommissioning operations, using the Helix-designed intervention riser system (IRS), which features an innovative high-angle disconnect system.

With its open deck plan and triaxial configuration, the Q7000 is capable of a wide range of production enhancement operations, in addition to well cleanup and field development support. It is equally optimized for well decommissioning activities, including suspension, tubing removal, tree recovery, and seafloor clearance.

A sophisticated 600-metric-ton well intervention tower with both active and passive heave compensation is located on the upper deck. The large flush deck features a skidding system for well intervention support equipment and tubulars storage.

Below deck are twin work-class ROV systems, bulk fluids storage, and pumping systems.
