|Situation:||Safe pig receiver trap opening|
|Result:||Prevention of production losses during pigging campaign|
Epic Energy is one of Australia’s leading infrastructure companies and operates two major gas transmission systems. One of them is the Moomba to Adelaide Pipeline System (MAPS), almost 1.200 km long, constructed in 1969.
As with so many aging assets, also MAPS is suffering of problems caused by leaking valves. One of these valves is a 22″ pig trap isolation valve. It is a single, burried ball valve, with a body cavity conduit access just above ground.
The problem of this valve passing is easily mitigated by the DBB-SAVER technology. The equipment was air freighted to Adelaide and will stay with Epic Energy for the duration of a pigging campaign for a period of 24 months, providing safe pig trap access for the ILI run and a number of scraper runs before that. Making sure there will be zero leakage, safe pig trap opening is guaranteed and planning issues are avoided. The inspection can now be performed without delays, without any safety issues and without any outages.
