Abstract
Developing deepwater oil and gas resource is the trend of oil industry development. It is important to select a proper development scenario and riser system which works as a key tool to connect subsea equipment and surface body in a deepwater project. Based on the West Africa’s deepwater target field CNOOC owned, this paper designs a detailed development scenario-FPSO +SPS +Shuttle tanker according to the following factors: well, reservoir layout, environment, floaters availability, commercial considerations. Floater and riser selection interact with each other. Considering the development scenario, a basic method for selecting a proper riser system is presented. As a result, FSHR is selected from existing risers based on technology, reliability, risk and cost.
