Hydril Conventional Ram BOP

Hold Pressure at 15,000 psi from 30 ° F to 500 ° F

Hydril Conventional Ram BOPs deliver proven reliability for safe operation from surface applications all the way to the harshest subsea environments. Rated for water depths to 11,500 ft, the Conventional Ram can work on the seabed continuously for as long as a year. It also can add hundreds of hours of drilling time annually when configured to seal upside-down as a Subsea Stack Test Valve (SSTV) so that required pressure tests can be completed with the drill pipe in place. In the lab, Hydril ram BOPs have:

  • Held full rated working pressure at 300 ° F for 8 hours using blind/shear rams. The tested unit then completed 3 additional closing cycles at low and high pressure.
  • Passed API temperature testing to 350 ° F using blind/shear rams.
  • Passed API temperature tests to 500 ° F using 5" fixed-bore rams. All fixed-bore ram sizes on the 18-15 Conventional Ram are rated for this temperature.
  • Passed API pressure tests at temperatures as low as 30 ° F for 5-1/2"-7-5/8" and 4-1/2"-7" variable rams.
  • Sheared large-diameter pipe (16”, 109 lb-per-ft, P-110) using optional, high pressure, 4,000 psi, 22" operators.
