HOUSTONCameron (NYSE:CAM) has introduced its Mark IV control system, featuring a redundant, three-point of distribution (POD) design as an option for its subsea BOPs.

Current subsea BOP control systems use a two-POD design, which provides a redundant spare. If the primary POD becomes unavailable, drillers can switch to the second POD to control their BOPs and seal the well before bringing the BOP stack to the surface for repair.

Cameron introduced the first multiplex BOP control system for subsea drilling and has developed a patent-pending three-POD stack design, which will provide drillers with additional operational reliability through redundancy. Adding a third POD can improve the subsea control system’s availability to as much as 98%, and reduce the likelihood of a POD-related stack pull by up to 73%.

The new POD design also offers increased functionality in a smaller, lighter package. The simpler design can reduce leak paths by using 50% less tubing compared to Cameron’s previous two-POD design. Additionally, the number of available functions has increased 33% to accommodate newer, eight-cavity stacks. POD size was reduced 26%, and weight is one-third less than other control PODs.
