CHIEDAM, the NetherlandsHuisman Equipment BV has secured a contract from Helix Energy Solutions Group Inc. for the delivery of a well intervention system onboard Helix’s newbuild semisubmersible Q7000. The system, which is based on Huisman’s multi-purpose tower (MPT) design, will be built by the Huisman production facility in China.

The 800-metric ton (882-ton) well intervention system will be capable of handling the intervention stack, the high-pressure riser, and other components. The active heave compensation hoist system of the MPT is designed to provide for safe landing of equipment at the seabed, while the passive heave compensation system offers a safe and redundant means to supply top tension to the risers. A guide trolley, traveling the entire length of the tower, will guide the subsea modules during lifting operations.

The system will also feature multiple transfer hatches that can be used to move equipment into the well center, and a skiddable work floor covering the moonpool flush with main deck. The skiddable work floor will allow large subsea modules to be deployed without the need for a raised work floor. When large objects need to pass the moonpool, the work floor can be skidded aside. In closed position, the work floor will be flush with the main deck, which will help to reduce risks and improve equipment handling on deck.

In addition to this well intervention system, Huisman will also supply a 150-metric ton (165-ton) knuckle boom crane and a 160-metric ton (176-ton) pedestal-mounted crane.
