There are marginal oilfield discoveries in Indonesia which cannot justify installation of fixed production platforms but can still be economically developed. The solution to these marginal oilfields is the utilization of unique Floating Production Systems (FPS). The FPS is becoming more accepted as off-shore construction costs continue to increase and these relatively low-cost production facilities are proving to the most economical method of production in marginal fields such as encountered off the coast of Indonesia. These FPS's are self-contained, complete with modern accomodation for production personnel and are equipped with the latest in production systems.

Such floating production systems are currently operational in the Aijuna "MM", "FF" and "F" fields, Java Sea, for Atlantic Richfield Indonesia and they are proving to be attractive in determining reservoir behaviour, probable reserves and are proving to be ideal in minimizing initial capital expenditures required for permanent production platforms.

This paper is intended to describe the economics of the unique Floating Production Systems and to also discuss the selection of equipment and operational experience.
