Offshore ram-type BOP
Extend proven high-quality, reliable BOP design expertise to a lighter-weight design.
Off-center tool joint shear rams
BroadShear rams can successfully shear wireline and drillstring components previously considered unshearable, such as tool joint hardbanding and off-center tubulars—all in a single stroke.
Engineered with enhanced metallurgy for exceptional strength and control, BroadShear rams are the culmination of years of experience in shearing tubulars to provide an innovative approach to meeting upcoming regulatory requirements.
The ability to shear the drillpipe inside the BOP has long been a regulatory requirement. In a dangerous kick situation, the subsea controls trigger a defined sequence of functions, including shearing the drillpipe. Operators must have confidence that the shear rams inside the BOP will shear the pipe and allow the rig to disconnect and move off site.
BroadShear rams reliably shear casing diameters up to 16 in, as well as tool joints, hardbanding, and wireline. The tool joints can even be sheared off-center. With these advances, more drillstring components can be sheared than ever before.
In a series of rigorous tests, a single set of BroadShear rams successfully sheared various drillstring components seven times. These tests included through the pin/box, hardbanding, and off-center components. These tests are some of the toughest shear tests performed in the industry to date.
According to our engineering analysis, BroadShear rams reduce the time that unshearable drillstring components are across the BOP rams from approximately 10% to 2% for a hole depth of 25,000 ft and standard tripping procedures.
In 2019, the Bureau of Safety and Environmental Enforcement (BSEE) updated its Well Control Rule originally released in 2016, which requires that a subsea BOP system must have the following mechanisms and capabilities:
BroadShear rams are already capable of exceeding the shearing requirements within this rule, providing you with more progressive technology to help you better achieve complex subsea objectives.
