In-Riser Revolution

The compact nature of the Revolution valve and actuator components is extremely beneficial for subsea in-riser applications. A short valve is more easily accommodated to sit below drilling BOPs which have irregular shear ram spacing and can frequently be very restrictive.

In-Riser Revolution

The compact internals also leaves substantial material available in the body which can be utilised to provide preloaded end connections, such as a flange. These connections are mechanically superior to non-preloaded connections and extremely desirable where cyclic loading is possible.

To date, Interventek has delivered 6 5/8” 10K psi and 6 3/8” 15K psi versions of theirRevolution valve to the field. The valves are designed to be suitable for in-riser well completion and intervention landing string systems.

Interventek launched the world’s first 5 1/8” 20k valve configuration in 2017 after successful testing. This ultra-high pressure, high temperature (HPHT) version of the 15kin-riser valve is able to withstand working pressures of 20,000psi and temperatures up to350 degrees Fahrenheit. There are currently no other 20k in-riser well intervention valves on the market and the new product line was developed to support moves into more challenging HPHT, deep water well environments, particularly in the Gulf of Mexico.
