The company has a group of cooperation teams engaged in the Sucker rod BOP industry for many years, with dedication, innovation spirit and service awareness, and has established a sound quality control and management system to ensure product quality.
The BOP, a primary component of the subsea drilling stack system, contains wellbore pressures by sealing around or shearing through drillpipe, as necessary. A subsea control system’s point of distribution (POD) is the component by which BOPs and other parts of the subsea stack are operated, often in water depths up to 3,658 m (12,000 ft). Retrieval of the subsea control system POD for unexpected maintenance can cost drillers several days of downtime and millions of dollars.
Conventional subsea BOP control systems use a two-POD design, providing a single redundant spare POD. This means that if the primary POD becomes unavailable, drillers can switch to the second POD to control the BOPs and seal the well before bringing the BOP stack to the surface to repair the nonworking POD. Unfortunately, this also means that the stack still must be pulled for repair if one of the two PODs fails.
In response to the need for added redundancy to further reduce downtime, Cameron has introduced its Mark IV high-availability (HA) control system, featuring the industry’s first three-POD design as an option for subsea BOPs, which eliminates the need to pull the stack if the primary POD fails.
