InterMoor recently completed installation of the drilling and production conductors for the Papa Terra project, announced Global President Tom Fulton.

Petrobras serves as the operator of the Papa Terra concession with a 62.5 per cent interest; Chevron holds the remaining 37.5 per cent interest.

InterMoor was responsible for the design, procurement, fabrication and installation of 15 conductors for the project. Fabricated at InterMoor’s 24-acre, Morgan City, La, facility, the conductors are 36in (91cm) in diameter and 187ft (57m) long.

InterMoor chartered Skandi Skolten, DOF Subsea’s construction anchor handling vessel, and an installation barge with a customized conductor launch system.

For conductor driving, InterMoor used MENCK’s MHU-270T DWS which included a deepwater hydraulic hammer capable of providing a driving energy of 270 kilojoules at a water depth of 3,281ft (1,000m) 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 minimalizing environmental impact and energy loss.

The conductors were installed in water depths of 3,937ft (1,200m) in the southern Campos Basin off the coast of Brazil.
