In deep and ultra-deep water, there is no room for failure: while the potential of high pressure reservoirs are huge, so are the risks.

A subsea development with high wellhead shut-in tubing pressures (SITP) may need to be designed with a high integrity pressure protection system (HIPPS), to enable the subsea facilities downstream of the HIPPS to be designed to a rated working pressure lower than the SITP, therefore making the project more cost effective.

In some applications, the addition of high pressure wells to an existing infrastructure may also require the use of HIPPS.

ATV has designed, qualified and delivered the first subsea HIPPS valves for the ultra deep water of the Gulf of Mexico (3000 m / 10.000 ft water depth): a valve block containing two hydraulically actuated 5 1/8” - 15,000 psi T.C.Slab Gate valves, with pressure sensors and injection valves. It is able to close in less than 2 seconds. 

Several challenges encountered and successfully solved onto project path, with relevant milestones for our continuous growth, e.g. advanced optimization of our design, able to ensure the requested safety closing time of the 5 1/8” Double Slab gate valve within 2 seconds, at the rated maximum pressure and water depth, as well as the first application of our hyperbaric chamber to perform integration testing as requested by RP 17O.
