WOM’s WU Ram BOP is pressure energized and features hydraulically operated locking mechanisms to hold the rams closed without actuation pressure. The WU Ram BOP operating system is designed to provide a fast and reliable seal around pipe or casing in the well bore, maintained even with loss of closing pressure.
Ram packing materials are generous and self-feeding, in addition to being quick and easy to replace. Hydraulically opening bonnets allow for easy access to replace rams or change rams with several other compatible ram configurations. All operating parts can be replaced on site.
Due to a fully integrated manufacturing line, WOM has complete control over the manufacture of BOP units to ensure conformity to API regulations
WOM’s Annular BOP has a conical bowl designed piston with a length-to-diameter ratio approaching 1 which eliminates tendencies to cock and bend during operations with off-center pipe or unevenly distributed accumulations of sand, cuttings, or other elements.
The piston and packing unit are the only moving parts, ensuring minimal wear. This design enhances the ability of the packing unit to reopen to full bore position. When engaged, the pipe may rotate and tool joints stripped without breaking the seal. When an annular seal is achieved, well pressure reinforces the seal.
Field-replaceable wear plate in the BOP head serves as an upper non-sealing wear surface for the movement of the packing unit, making field repair fast and economical. A piston stroke measurement indicator indicates remaining packing unit life without need for dis-assembly and ensures the longest and safest use of the packing unit.
