Annular Spherical BOP
Our WSB annular BOP features a reliable, compact design with retrofittable swarf seal technology.
- Rugged, reliable spherical type sealing element – Provides positive seal after hundreds of tests to full working pressure
- Enhanced swarf seal – Designed to help prevent metal-to-metal damage from swarf entering the piston when performing milling
- Strong, simple construction – only five major parts
- Compact body saves space – Height is 15 to 20% less than equivalent annular BOP designs
- Simple hydraulic system – Optimized to only require two hydraulic connections for operation
- Wear rings on moving parts – Feature prevents metal-to metal contact, allowing for prolonged preventer life.
- Resistant to corrosive environments – Standard models are suitable for internal H2S service, and simple bolt and lifting shackle changes convert them for external H2S service.
- Ease of Service – Element can be replaced without contamination of mud or grit into the hydraulic system
