The invention discloses a separation-combination type offshore spilled-oil recovery method and system. The method comprises the steps that an oil containment boom is used for delimitating an operation area after workers reach a scene, and a secondary ship is separated from a primary ship to enter water for work; the secondary ship sucks a high-concentration oil-water mixture into a first-level working area of the secondary ship, and in the first-level working area, the oil-water mixture is circularly subjected to dewatering, standing separation, water drainage and dewatering; the oil-water mixture subjected to standing separation will form a separation layer, the secondary ship sucks out upper-layer oil contamination for storage, and the rest of the mixture is drained into a second-level working area of the secondary ship; in the second-level working area of the secondary ship, oil-absorbing felt is used for removing surface floating oil, and remaining clean sea water is drained into sea; the secondary ship conveys the stored oil contamination which is processed for two times into the primary ship; after work is finished, the secondary ship is driven back to the primary ship, the secondary ship is sucked to a lifting machine of the primary ship through an automatic positioning device, and the secondary ship is fixed and lifted up through the lifting machine.
