ARCO and Pertamina joined to build a totally offshore NGL facility in the Java Sea. ARCO serves as operator for a group of American firms which have a production sharing contract with Pertamina, the Indonesian state-owned oil company.
The plant includes systems for gas gathering, gas compression, dehydration, chill-down and turbo-expansion, fractionation and LPG treating, spiking excess gas liquids back into the crude, and product shipping facilities.
The facility consists of two interconnected eight-pile platforms for the NGL process plant, one four-pile platform for crew quarters, four four-pile compressor station platforms, flare platforms and bridges, 40 miles of submarine pipeline and a single-point mooring system for a 375,000 bbl capacity refrigerated storage barge.
