摘要 |
This invention relates to a system for the development of one or more offshore hydrocarbon fields (40,40') comprising at least one floating hydrocarbon processing unit (1) that is moored to the seabed (21) and connected to a hydrocarbon reservoir via a riser (2) and a wellhead (3) on the seabed, the unit receiving and processing the hydrocarbon mixture received from the reservoir via the riser, the floating hydrocarbon processing unit being provided with process equipment to separate from the received hydrocarbon mixture the oil, water and gas and provided with storage tanks (12) for storage of the separated oil, a gas storage buffer reservoir (7) placed at a certain distance from and isolated from the hydrocarbon reservoir, a gas export riser (5) connected to the floating hydrocarbon processing unit and the gas buffer reservoir to export the separated gas from the hydrocarbon processing unit and inject the gas into the gas buffer reservoir for temporary storage of the produced gas, and, a gas riser (8) connected with one end to the gas buffer reservoir and with another end connected to a floating gas processing unit (9) for processing the gas received from the gas buffer reservoir so that the gas can be transported to shore. |
