/ Well Intervention Systems

Well intervention operations represent a large portion of the total field lifetime costs. Therefore reducing these costs will significantly increase the field economics. Until now, most of the intervention work has been performed by large, expensive drill ships and semi-submersibles. By performing the well interventions from dedicated vessels, the workover costs can be reduced significantly and the drilling rigs can focus on drilling activities again. With the fast rising number of subsea wells and the promising results with recent well interventions, oil companies are starting to see the benefits of a purpose built well intervention solution.

 

To serve both the open water and the riser based well intervention markets, Huisman developed two seperate systems. Both systems are based on the Multi Purpose Tower which is responsible for all vertical movements of the equipment on board. The MPT has the same functionality as a normal derrick but offers improved accessibility to the well centres. This allows for improved handling procedures that increase efficiency and safety. The superior accessibility to the well centre and small footprint of the MPT are ideally suited for well intervention and subsea installation services. Subsea equipment can be skidded into the well centre from three sides, giving optimal flexibility.

 

Over the years, we have delivered various well intervention systems for Helix Energy Services (Q4000, Well Enhancer, SIEM 1, SIEM 2 and Q7000) and Otto Candies.
