Hydrocarbon fluid separation at an offshore site and method

摘要

An offshore marine structure and method, which structure includes a leg supported deck which holds hydrocarbon fluid processing equipment above the water's surface, and includes vertically aligned conductor guides. A self supporting fluid separator is positioned in said marine structure to receive a multi-phase stream of a hydrocarbon fluid from one or more wells. An upper segment of the fluid separator is slidably registered in vertically aligned conductor guides. A lower segment of the separator is embedded in the sea floor and operably engaged with said upper segment. A conductor riser is adjacently positioned by conductor guides in the marine structure to receive hydrocarbon liquid from the fluid separator. Discrete liquid, and combined vaporous flows are then conducted to the processing equipment for further handling.
