Atlas Copco Rental’s first 150 bar booster in Asia has been delivered to the PT McDermott fabrication yard in Batam, Indonesia for pressure testing piping modules bound for Chevron Australia’s Gorgon Project in Western Australia.
The complete Atlas Copco installation features two class zero certified 100% oil-free PNS1250 air compressors, dryers and manifolds plus the 150 bar B18-62/2250 2-stage reciprocating-type booster.
Housed within fully weatherproof canopies the two PNS1250 compressors each provide a free air delivery of 1250 cfm, 35.4 m3/min at 24 bar.
This 100% oil-free air is fed through a manifold and SD150 dryer into the booster.
Only recently introduced, the Atlas Copco B18-62/2250 booster is a 2-stage, reciprocating-type compressor and provides a suction pressure of 350 psi, 24 bar and a maximum discharge pressure of 2250 psi, 155 bar to ensure a maximum pressure of 2185 cfm, 62 m3/min.
The 2-stage booster is rig-safe and can be used on pipeline and dewatering projects globally.
Installed as a permanent installation for the 12 month plus rental contract by PT McDermott, the Atlas Copco system is used for 2000 psi, 150 bar pressure testing LNG modules. The testing is carried out using skid-mounted ‘long toms’ which are initially pressurized to the required test pressure and then transported to the module site and connected to the modules testing point.
The LNG train modules, once tested, are shipped to Chevron Australia’s Gorgon Project in Barrow Island, Western Australia; a 3-train LNG production facility.
