Customer

Petronas Carigali SDN BHD is the exploration and operation company, subsidiary of Petroliam Nasional Berhad (Petronas), The National oil company of Malaysia. RNZ Sdn Bhd was appointed as the FEED and detail design engineering contractor.

Project

Tangga Barat Cluster (TBC) development project consists of four (4) fields; Melor, Laho, Tangga, and Tangga Barat. The location of the fields is offshore Terengganu, east coast of Malaysia. The treated gas from TBC will be transported to shore via Resak On Shore Terminal (OGT) to meet the Peninsular Malaysia Gas Utilization (PGU) gas demand. TBC is located about 185 km offshore in the PM-313 blocks in a water depth of approximately 70 m. The current plan is to drill twenty-seven (27) wells and production will be processed at the centralized platform at Tangga Barat, TBCP-A. The gas then will be transported to Resak OGT via export compressor at Resak Platform RCPP. It is an intention by PCSB to develop an optimum scheme to maximize its hydrocarbon reserves.
