Helix MPT order for Huisman

Wednesday, October 9, 2013

Drilling, lifting and subsea solutions firm Huisman has won a new contract from Helix Energy Solutions Group for the delivery of a well intervention system.

The new system is for Helix’s new-build semisubmersible Q7000. The system, which will be based on Huisman’s multi purpose tower (MPT) design, will be built by the Huisman production facility in China.

The integrated 800-tonne well intervention system will be capable of handling the intervention stack, high pressure riser and other components.

The Huisman MPT has the same functionality as a normal derrick but offers improved accessibility to the well center, which allows for new improved handling procedures that increase efficiency and safety. 

The active heave compensation hoist system of the MPT provides a means for safe landing of equipment at the seabed, while the passive heave compensation system provides a safe and redundant means to supply top tension to the risers.

A guide trolley, travelling the entire length of the tower, guides the subsea modules during lifting operations. The system also features 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 allows 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 is flush with the main deck, which significantly reduces HSE risks and improves equipment handling on deck.

In addition to the well intervention system, Huisman will also supply a 150-tonne knuckle boom crane and a 160-tonne pedestal mounted crane.
