Our drilling BOP includes an annular BOP and a ram BOP. The annular BOP, consisting primarily of a shell, a header, a rubber core and a piston, and which by design is equipped with a hydraulic control system, can be used independently but usually operates in tandem with a ram BOP.
In accordance with API 16A requirements, the connections at the top and bottom of the rig are either flange or studded flange and can be conveniently connected to a drilling spool or ram BOP.
Our ram BOP features an advanced design that is nonetheless easy to operate.
The ram BOP is reliable, and spare parts can be easily replaced. As with the annular BOP, it can be used independently or coupled to other BOP combinations.
A hydraulic system can be used to open and close the ram, but should there be no power or air on site to run this system, the rams can be opened or closed manually.
