The invention relates to a positioning ship and a construction method for assisting in sinking and positioning of a steel open caisson thereof, belonging to the field of sinking, implanting and positioning of the steel open caisson in bridge construction. The positioning ship comprises a ship body, wherein a plurality of fixed seats are arranged on a deck in the middle of the ship body side by side; steering horse mouths are arranged at the two ends of the ship body, and a plurality of pulley blocks are respectively mounted between the steering horse mouths and the fixed seats; each pulley block comprises two groups of pulleys, and the pulleys are connected by winding a steel wire rope; one end of the wound steel wire rope is fixed, and the other end is movable; one end of each pulley block is connected with each fixed seat, and the other end of each pulley block is connected with a driving cable or anchored rope of the positioning ship; a winch is arranged on the deck. During working, the movable end of the steel wire rope in at least one pulley block is connected with the winch. The tilt and offset of the steel open caisson in the sinking process are adjusted through the driving cable of the positioning ship, meanwhile the stress of a spud is reduced, and the positioning accuracy and the construction safety of the open caisson are ensured.
