Hydril 11” 20,000 PSI HP/HT BOP System

The Hydril 11″ 20,000 psi HP/ HT BOP System delivers unique and proven reliability for ultra-HP/HT drilling, well testing, completion and intervention operations both on- and offshore. HOS has set the performance expectations for pressure control equipment in the world with the first ever successful deployment of a 20,000 psi BOP System on a gas exploration well in the Norwegian sector of the North Sea.


All equipment is manufactured in accordance with API 16A and NACE MR-01-75 standards and fully OEM certified complete with IRC, COC and ABS (CDS Standard) until Q3 2020 as well as API monogrammed.

As part of our bespoke, flexible HP/HT solutions, the following is available:

  • Complete 20,000 psi FMC / NOV flow iron package which is specifically developed for ultra-HP/HT and sour service operations
  • A selection of fixed rams for both tubing and drillpipe in sizes between 1 ⅜” to 7 ⅝”
  • Ability to custom configure for emergency response applications such as capping and snubbing operations
  • Bespoke higher specification elastomers

In-house well control engineering, training, risk prevention evaluations, well control equipment audits and operational support (including health and safety related activities) for each HP/HT project with a team of subsea engineers, pressure control equipment technicians and world class drilling, completion and intervention experts which has proven to reduce and prevent risks in the planning and operational phases.
