Through the flexible oil shipment duct which is insulated the method from the floating body type petroleum production structure of replenishing the petroleum in the shipment buoy

摘要

This invention regards the method from the 1st floating body type structure of replenishing the petroleum in the shipment structure. Method extends between the structures of the aforementioned two which is the depth of water of 50m or 500m, step and the 2C or the 20C where it consists of the flexible erasutoma material and at least inside diameter and of 600mm the length it provides one pump at least in step, and the aforementioned 1st structure which provide the flexible duct where have 1500m or 3000m with the pressure of 5 bars/var or 30 bars/var and 1000 or through the aforementioned duct with flux of 50,000m3/time, the step which sucks up the petroleum include, provide the single flexible duct, desirably in the water temperature of the 2C or the 10C, the petroleum in the aforementioned 1st structure inlet temperature Tin and,It possesses outlet temperature To in the aforementioned 2nd structure, Tin-To below the 15C, desirably, features the step which provides the wall thickness of the aforementioned kind of duct which is under the 5C.
