Subsea Compact Shear-Seal Valve
Our Compact Shear & Seal (CSS) BOP valve is a modular and stackable assembly designed for open-water subsea well intervention operations where reduced size and weight is advantageous. It can simplify wellsite handling and logistics and improves efficiency and safety by avoiding heavy lifting and access restrictions.
As a dual, triple or quad stack up, the BOP can deliver both pipe ram and shear ram functionality.
The CSS is 50% lighter than conventional designs, weighing less than a tonne and measuring approx. 850mm x 540mm x 500mm. As a dual stack up the size is just 850mm x 1080mm x 500mm (33.5” x 19.75” x 42.5”). It is available as a 5-1/8” or a 6-3/8” bore assembly with a pressure rating of 5,000 psi, a shear rating of 100,000 lbs and is suitable for slickline, braided line, e-line cable, hollow rod, coiled tubing up to 2-7/8” (80-130ksi) and e-coil.
The modular addition of the seal ram block paired with the shear and seal block enables seal function or shear and seal function independently or simultaneously. Changeable inserts allow for simple field replacement of seals or to configure for a different size. Triple or quad stack ups are also possible.
We have reduced the size and weight by housing the actuators and pistons within the assembly so that the rams can be operated in a much smaller envelope than conventional BOPs. This helps to simplify wellsite handling and logistics and improves efficiency and operational safety by avoiding heavy lifting, access hatch restrictions and height constraints.
When integrated with our Rigless Subsea Access System (RSAS), the space and efficiency savings are further multiplied, allowing safe and reliable rigless intervention with a reduced footprint . The design also allows easy in-field maintenance and seal and ram replacement without requiring a crane.
The CSS can be supplied as part of a serviced package alongside our SIS or RSAS, or on an individual sale or rental basis for onshore and offshore applications. Crossovers are available to integrate with clients’ rig-up configurations and training in redress and maintenance can be provided.
