Product Overview
The 30″ 1M WP Annular BOP is an ultra-large-bore spherical blowout preventer designed for the largest-diameter well control applications. With a massive 30-inch bore (762 mm) and 1,000 psi working pressure rating, it provides essential annular sealing capability for surface casing drilling, offshore conductor operations, and large-diameter well intervention. The compact spherical design features only five major components and a fully interchangeable sealing element. Constructed to API SPEC 16A standards with NACE MR-0175 compliance for sour service environments.
Bore: 30″ (762 mm) — Ultra-Large Diameter | Working Pressure: 1,000 psi | Test Pressure: 1,500 psi | Weight: 38,581 lb (17,500 kg) | Standard: API SPEC 16A

Key Features
- 30-Inch Ultra-Large Bore: The largest-bore annular BOP in the CAMTOP portfolio — 762 mm through-bore for conductor casing and large-diameter well operations
- API SPEC 16A Compliant: Designed and manufactured to international standards for annular blowout preventers
- 1,000 PSI Working Pressure: Rated for 1,000 psi with 1,500 psi hydrostatic body test pressure — optimized for surface and conductor applications
- Shaffer-Style Interchangeable Design: Structurally equivalent to Shaffer annular BOPs with fully interchangeable sealing elements for maintenance simplicity
- NACE MR-0175 Compliant: Suitable for H2S sour gas service environments with appropriate material selection
- Ni-Based Alloy 625 Ring Grooves: All ring grooves welded with nickel-based alloy 625 for superior corrosion resistance in conductor housing applications
- 13.78″ Piston Stroke: Extra-long piston stroke for complete sealing element actuation across the full 30″ bore
- Wear Ring Protection: Moving parts equipped with wear rings to prevent metal-to-metal contact and extend service life
- 5 Major Components Only: Simplified assembly — upper housing, body, piston, adapter ring, and sealing element — reduced maintenance complexity
- Full Bore Sealing Range: Seals on tubular sizes from 0 to 30″ for maximum operational versatility
- R95 Studded/Fanged Connections: API R95 1M connections for 30-inch wellhead and conductor integration
- T-20 Temperature Rating: Metal materials rated -29°C to +121°C for standard drilling environments
