Offshore Pressure Control Equipment

Well Control
Assessing risk potential on your rig is crucial to ensuring safety before, during and after problems occur. HMH’s proven well control systems are configured to anticipate and combat the risks of everyday operations—even in the toughest environments. Trusted worldwide to provide reliability, operational performance, and configuration flexibility, HMH’s well control systems mean improved safety and increased uptime.

HMH is focusing on the next steps
With an all-electric BOP from HMH it is possible to increase the reliability, reduce downtime, reduce weight, eliminate release of control fluid and increase efficiency and functionality. Our electric control systems can be used both for new BOPs and for conversion of existing BOPs.

HMH is also developing marine riserless drilling solutions and a key component to achieve this is our wear resilient rotating control device.

The best in the business
Drilling contractors have called the GX™ Annular BOP “the best annular in the business” for two reasons: exceptional performance, plus maximum uptime. The single packing unit has provided continuous service for up to one year, and it has continued to hold pressure after exposure to extreme temperatures and extensive stripping. The GX can strip and seal on all pipe sizes and achieve complete shutoff­—in the field and in laboratory tests.

Our 18¾” Compact™ RAM BOP is designed to hold pressure at 15,000 psi from 30°F to 500°F, is rated for water depths to 10,000+ feet, and has worked on the seabed continuously for one year during drilling of a 34,000-foot well. It can also add hundreds of hours of drilling time annually when configured to seal upside-down as a subsea stack test valve (SSTV), so required pressure tests can be completed with the drill pipe in place.

Our BOP systems increase uptime, reduce unplanned stack pulls, and lower between-well maintenance time to service system components. With best-in-class availability, operating ease and proven high-pressure performance, you can worry less and achieve more.

Key advantages include: 

  • Increased uptime and availability
  • Reduced between-well maintenance time
  • Fewer unplanned stack pulls
  • API-monogrammed
  • Approved by pressure tests
  • Approved by high-temperature tests of up to 500°F
  • Range of models to meet your specific needs
