DLWS BOP

DLWS ram-style BOPs offer field-proven reliability to seal around drill pipe and across open hole. Compared to other ram preventers they feature a low overall height so minimum space is required. Single and double-cavity models are available; doubles save space and weight by combining two ram compartments into one unitized body.

Type DU BOP

Type DU Blowout Preventers feature the widest range of sizes and are the most widely used style of BOP. Well-bore pressure acts on the pressure-energized BOP to increase the sealing force and maintain the seal in the event of hydraulic pressure loss. Available in singles or doubles, they can be configured with a manual or hydraulic operating system.

When shearing force is required, type DU BOPs can be supplied with shear bonnets and tandem boosters.
