New Cameron systems address subsea and horizontal well challenges

A subsea control system’s point of distribution (POD) is the component by which blowout preventers and other parts of the subsea stack are operated, often at water depths of 12,000 ft. Cameron’s new Mark IV High-Availability (HA) BOP control system—the industry’s first three-POD design—increases subsea-control system availability by up to 98%, Fig. 1. For operators, this offers greater protection against downtime resulting from adherence to standard practice, which demands that the entire stack be pulled if one POD fails on two-POD control systems. Any BOP stack retrieval to repair a malfunctioning POD can be particularly costly for deep- or ultra-deepwater projects. Accordingly, Cameron has added a third POD to its Mark IV two-POD BOP control system design.
