Full field development
Full field development consists of Central Processing Facilities (CPF), onshore and offshore pipelines and a floating storage and offloading facility. The CPF, situated about 10 km southeast of Cepu and 20 km southwest of Bojonegoro in the center of the oil field, will process and treat the crude oil produced.
The treated oil will be transported through a new 20 inch insulated buried pipeline to the coast at Tuban and thereafter through a subsea pipeline to a Floating Storage and Offloading (FSO) facility. Oil transportation tankers will load crude oil from the FSO for transportation to domestic and world markets.
