Oil-water separation ship for treating offshore crude oil leakage

The invention discloses an oil-water separation ship for treating offshore crude oil leakage, and relates to the technical field of oil-water separation ships, the oil-water separation ship comprises a ship body, an oil-water separation device is arranged in the ship body, the oil-water separation device comprises an oil receiving tank fixedly installed on the ship body, and a plurality of oil pumping pipelines are arranged on the ship body. The multiple oil pumping pipelines are internally communicated, one oil pumping pipeline is communicated with the interior of the oil collecting tank, a composite net is fixedly connected to one side of the ship body, and the two oil pumping pipelines are communicated with the interior of the composite net. Through cooperation of the separation cylinder, the mechanical protection net, the copper phosphate inorganic membrane and the oil-water separation membrane, oil and water are separated through centrifugal force generated when the separation cylinder rotates, water is
