Dulang A is one of three 32-slot fixed wellhead and drilling platforms installed across the field; Dulang C and Dulang D perform equivalent satellite roles. Its steel jacket supports surface wellheads, production and injection manifolds, well-control equipment and the utilities required for a satellite installation. The field’s production and injection duties are distributed among the three platforms and include oil producers, water injectors and wells used in the immiscible water-alternating-gas programme. Full wellstream from Dulang A is transported by subsea pipeline to Dulang B, the central integrated production platform. Dulang B performs oil, gas and water separation, crude stabilisation, produced-water handling and field-fluid pumping. The field’s injection system reinjects treated seawater and produced gas to support reservoir pressure and improve sweep. Centralised utilities and control at Dulang B support the satellite platforms through the field’s pipeline, power and communications network. After stabilisation, crude is pumped from Dulang B through a submarine pipeline to the dedicated Dulang FSO, moored approximately one nautical mile away. The FSO stores the crude and transfers it to export tankers through a tandem-offloading arrangement. Dulang A itself has no bulk processing train, living quarters, crude storage or tanker-loading system. Its permanent safety and support equipment includes emergency shutdown, fire-and-gas detection, chemical-injection interfaces, telecommunications, navigation aids and marine-access facilities.
