InterMoor Completes Conductor Fabrication And Installation For Shell BC 10 Phase 2
InterMoor, an Acteon company, has completed the installation of the Electrical Submersible Pump (ESP) Conductors forthe artificial lift manifold as part ofthe Shell BC-10 Phase 2 project, announced InterMoor Global President Tom Fulton.
InterMoor was responsible for the fabrication and installation of fourconductors in addition to one spare conductorforthe project. Weighing in at more than 70 metric tons, the conductors measured48 inches in diameter and60 meters long with a 1.5-inch wall.
Fabricated at InterMoor’s 24-acre Morgan City, La., facility,the conductors were installed in water depths up to 5,600 ft. (1,707 m) off the coast of Brazil in the northern Campos Basin. The installation took place the last week of May 2012 utilizing DOF Subsea’s Anchor Handling Vessel SkandiSkoltenunder charter to Shell Brasil Ltda.
InterMoor provided an installation barge with a customized launch system to install the conductors through four corner holes in a template by self-penetration.InterMoor’s patented Suction to Stability(STS)operations and driving via MENCK’s deep water spread (DWS) subsea hammer and power pack were also utilized.
InterMoor used MENCK’s MHU-270T DWS which included a deepwater hydraulic hammer, capable of providing a driving energy of 270 kilojouleat a water depth of 3,281ft (1000m) combined with MENCK’s girdle-type electro-hydraulic power pack and umbilical support system.. Generating hydraulic power at depth, rather than at the surface, means no hydraulic hose, therefore minimal energy loss at depth and minimizing environmental impact.The tolerance requirements of less than1.0 degree verticalityand within six inches relative elevation were critical andcould not be achieved by traditional jetting methods from a semi-submersible. These tolerances were successfully respected utilizing InterMoor’s installation methodology in Phase 2, as they were for Phase 1.
“It was a tremendous advantage having personnel on the job associated with the previous BC-10 Phase 1 to ensure lessons learned were carried outsuccessfully. This factor waskey to executing the project safely, on schedule and on budget. We have demonstrated a capability which is valid across a number of deep-water projects in the industry,” said Fulton.
