IMI Critical Engineering has made a key contribution to a deep-sea oil extraction project in the Gulf of Martaban on behalf of PTTEP, a Thai petroleum and exploration company, and China Offshore Oil Engineering Company (COOEC).

Following a competitive tender process, IMI Critical Engineering’s Chinese-based IMI CCI business was awarded the $multi-million contract to supply 72 choke valves to the Zawtika project located 300 kilometres south of Yangon, Myanmar. The major development is the largest overseas offshore project operated by PTTEP, and has seen IMI CCI provide valves installed across each of its four platforms.

Due to the severe nature of the application, which must withstand intensive shocks due to high pressure and sand content from natural gas, the project required a supplier who could provide a reliable valve solution able to withstand severe applications. In addition to its reputation as a valve specialist, IMI CCI was appointed based on the inner cage design of its choke valve plug, which comprises Tungsten Carbide on the inside and Inconel 718 on the outside, helping protect the valve from intensive flush and vibration damage.
