s2, starting an electric air pump in the shipborne rapid air charging device, starting to charge an air charging capsule, slowly downwards placing the offshore oil stain storage device along one side of a ship in the air charging process, firstly moving one side without the air charging device towards the sea in the lowering process, and stopping lowering when the air charging device at the side of the offshore oil stain storage device is level with a deck of the ship;
s3, after the inflation of the inflatable capsule is completed, the electric air pump is turned off;
s4, opening a flange stop valve in the oil conveying device, conveying oil to the oil storage device, slowly lowering the offshore oil stain storage device, and stopping lowering when the offshore oil stain storage device is wholly positioned on the water surface;
s5, waiting for petroleum transportation, and when the oil full mark zone in the offshore oil pollution storage device is positioned on a horizontal plane, closing a valve in the oil transportation device by an operator to separate a ship from an oil transportation pipeline;
s6, opening an eye-shaped safety hook in the mooring device, separating the offshore oil stain storage device from the ship, and waiting for an operator to salvage.
Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature's illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "under" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "lower" may encompass both an upper and lower orientation. The device may be otherwise positioned (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Moreover, relational terms such as "first" and "second", and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.
The foregoing has described exemplary embodiments of the invention, it being understood that any simple variations, modifications, or other equivalent arrangements which would not unduly obscure the invention may be made by those skilled in the art without departing from the spirit of the invention.
