Abstract
In this paper, we describe an offshore process FEED (Front-End Engineering Design) method for oil FPSO (Floating, Production, Storage, and Offloading) topsides systems based on the concepts and procedures for FEED of general offshore plants. First, various activities of the general process FEED phase are defined and analyzed, and then the offshore process FEED method, which is suitable for application to all offshore oil and gas plants, is established. Finally, the established FEED method is applied to oil FPSO topsides systems in order to test its validity. This established process FEED method would contribute to performing successful offshore projects in the future.
