The invention relates to an output device of a non-single-point mooring crude oil storage facility on the sea. The output device of the non-single-point mooring crude oil storage facility on the sea comprises a mooring hawser winch arranged on a deck, a structural tower, a conducting rope device, a straight liquid rotating channel, an oil delivery pipe and an outer oil delivery pipe. The mooring hawser winch comprises a support, a cable rotating wheel and a mooring hawser; the steel structural tower comprises an upper layer operating platform, a middle layer operating platform and a lower layer operating platform; the conducting rope device comprises two guide pore plates, a guide pillar and a guide wheel; the straight liquid rotating channel comprises a fixing pipe segment, a slewing bearing, a moving pipe segment, an upper flange, a lower flange and the like; the steel oil delivery pipe is connected with an oil storage facility and the straight liquid rotating channel; the outer oil delivery pipe is connected to the straight liquid rotating channel and a shuttle tanker. The output device of the non-single-point mooring crude oil storage facility on the sea is used matching with a positioning tug, the straight liquid rotating channel can avoid the leakage loss resulting from the damage caused by the bending and torsion of the outer oil delivery pipe when outputting crude oil. The output device of the non-single-point mooring crude oil storage facility on the sea can be widely applied to the output process of the non-single-point mooring crude oil storage facility on the sea in the field of ocean engineering.
