The invention relates to an ocean platform submersible pump winding and unwinding method which comprises a hose winch (1), a combined hose (2), a submersible pump (3), a winch bracket (4), a winch barrel (5), a motor (6), a reduction gearbox (7), a control cabinet (8), a seawater output end (9), a hose guiding device (10), pump body guiding frames (11) and pile washing-out pipelines (12). The method is characterized in that the submersible pump (3) is connected to one end of the combined hose (2); the combined hose (2) is wound onto the winch barrel (5) on the hose winch (4); and the motor (6) and the reduction gearbox (7) are started by the control cabinet (8) to realize synchronous winding and unwinding of the submersible pump (8) and the combined hose (2). The method is simple, safe and reliable, is easy to operate, can meet the using requirement of a platform, has high adaptive capacity to environment, avoids being influenced by platform lifting, alleviates the operation intensity of submersible pump winding and unwinding, saves operation time and manpower and has high economic efficiency.
