Pig Launcher and Pig Receiver Contract Completed
(January 14th 2008)
PE has recently completed the design and fabrication of mobile pig launchers and mobile pig receivers for the Karachaganak Development Project.
The Karachaganak Development Project is a major $3.5 billion oil and gas development in Western Kazakhstan. The field was first discovered in 1979, covers 280 sq.km. and holds more than 1.2 billion tonnes of oil and condensate and more than 1.35 trillion cubic metres of gas.
The Tender, first issued in February 2006, was for:
x 2 - 20in. x 24in. Launcher pig trap mobile skid units suitable for sour service
x 2 - 20in. x 24in. Receiver pig trap mobile skid units suitable for sour service
These are for onshore flow lines and pipelines on the 635 km KPC Gas Export Line.
PE has particular expertise in the design and fabrication of pig traps, especially those required to meet more complex specifications and design codes. We were delighted to win the contract and have recently completed the fabrication of the pig traps.
PE was responsible for all aspects of design, testing and fabrication. These pig traps were complex and included a range of ancillary components and pipework. They are also mounted on serrated rectangular open grid galvanised steel flooring.
As part of this design and build, PE also carried out all testing to meet the necessary industry standards, including Pressure Testing, HIC (Hydrogen Induced Cracking) and SSCC (Sulphide Stress Corrosion Cracking) Testing.
Fitted to each pig launcher and pig receiver is our 24" Rapid Opening Closure (ROC), which is a pressure retaining structure that allows quick access to pipelines and pressure vessels.
Also fitted to each pig launcher and pig receiver is our Intrusive Pig Signaller which confirms the launch or receipt of a pig from or into the pig trap.
