Abstract

This study suggests a new concept of the subsea production system based on a large-scale seabed storage tank that stores the well fluid temporarily and later transfers it to the shuttle tanker through the riser. This concept was assessed to have advantages of reduction in the floater size, freedom from transportation distance, insensitivity to sea depth, and environmentally friendliness over the conventional deepsea solutions. Several flow assurance hazards for this system were expected, and appropriate design measures and operational methods against the hazards were suggested. A feasibility study was performed for an oil field which was located at 2190 m deep producing the well fluid of black oil type. The capacity of the seabed storage tank was considered to be 300,000 m3. Simulation results showed that riser diameter should be 19 inch and the insulation layer should be thicker than 100 mm.
