Above the shelf44, there is a crane53which can be driven to slide on the left and right on second gantry45and third gantry82. On the crane53, there is a trolley54sliding forward and backward. Under the trolley54, there is a sling52. Trolley54and sling52are connected by two fifth wire ropes51rolled synchronously by windlass. Under the sling52, there are two hooks50. When it comes to use the cargo carrier25for loading containers24to ship fuel, empty movable oil tanks48on the position44can be shipped to cabin26of cargo carrier25on fourth position80by crane53, or empty movable oil tank48in cabin26on cargo carrier25on fourth position80can be shipped on shelf44. There can be put three or four movable oil tanks48on shelf44.85is direction arrow that cargo carrier25be moved on the deck.

In order to keep the aircraft carriers and the replenishment oiler in the steady state, the operation of the marine lifting unit and a marine crane for loading and unloading of goods and materials on both sides should try to go on simultaneously.

Abeam replenishing rig on existing replenishment oiler's gantry can be still existed,43is an abeam replenishment oil pipe.

When starting replenishing, two sides of the gantry frame arm61hang vertically cargo carrier25on first position81and second position84. The two operators in control cab35of the replenishment oiler respectively operate the second windlass59to drag the first wire rope56in order to make slide frame63slide upward in front and rear frame bars of the gantry frame arm61, thus rising frame62, gantry74and cargo carrier25, operate the first windlass58to release the traction of the second wire rope57for the gantry frame arm61leaning gravity gantry74and the gravity of cargo carrier25swing in infer lateral direction to the horizontal position, then operate the second windlass59and the first windlass58to move cargo carrier25to loading/unloading position B, hook21is not separated from the cargo carrier25's ring22. After cargo carrier25arrives at loading/unloading position B, inform operators in loading/unloading ports5of two sides respectively of handling the arm of the crane arm2and crane arm77out to the loading/unloading ports5; inform driver in cargo carrier25of moving the second carrying board27to the middle of cabin26. Operator in container's loading/unloading ports5presses loading/unloading position A command key, inward sliding command key, falling command keys, locking command keys and rising command key to make container24suspend on the loading/unloading position A from loading/unloading position A by trolleys9and slings10, then presses outward sliding command key and the first carrying board6comes back to the cabin of the replenishment oiler. After the operator in control cab35takes over the operational control, presses B3command key, falling1command keys, unlocking command keys, lifting command key and loading/unloading position A command key to put the container24on the second carrying board27's B3and sling10rises. The trolley9comes back to loading/unloading position A. After staff in cabin of the replenishment oiler putting another container24on the first carrying board6, operator in loading/unloading port5presses inward sliding command key, the first carrying board6moves container24in cabin of the replenishment oiler to loading/unloading port5for the preparation of the second container24's shipment. The operator in control cab35first fills the lower layer, then fills the upper layer of container24on the second carrying board27according to the sequence of B3, B2, B1. After the second carrying board27is full of containers24, drivers move the second carrying board27back to the original position, and move the another second carrying board27to the middle of cabin26, after fill the container24according to the same order, move the second carrying board27to the original position, finally in the middle bottom of the cabin26, fill the container24according to the same order. When loading and unloading oil, the operators of two loading/unloading ports5respectively ride and operate operations cabs8and operation cabs75, moving to near cargo carrier25to connect respectively oil delivery pipes7in the two loading/unloading ports5to oil tank71or oil tank48on two cargo ships25for loading oil. The first operator's cab8is hanging on the trolley9, following trolley9for moving near to cargo carrier25. After the loading, the operators in two loading/unloading ports5respectively stretch crane arm2and crane arm77back to loading/unloading ports5. The operators in two control cabs35operate marine crane to put cargo carrier25completely into the sea, unlock lock bar42, separate the rear two hooks21and ring22, then separate the front two hooks21and ring22. The operator in control cab35informs drivers of setting sail, the driver drivers cargo carrier25to the aircraft carrier.

The operators in two control cab35operates respectively both sides of replenishment oiler marine crane's gantry frame arm61erect, the workforce in the replenishment oiler moves the cargo carrier25on ship carrying board67from fourth position80and third position83to first position81and second position84. The operators in two control cabs35hang cargo carrier25in the sea and move to B, then unload the oil.

When cargo carrier25drives near the aircraft carrier, operators in two control cabs35of the aircraft carrier operate respectively two hydraulic arms on the front of the marine lifting units on the two side to cooperate with the drivers in driving cab38to hook two rings22on the front of the cargo carrier25, then to operate respectively two hydraulic arms on the back of the marine lifting units to hook two rings22on the back of the cargo carrier25, Lock ring22with a lock bar42and move the cargo carrier25to the loading/unloading position B. After cargo carrier25moves to the loading/unloading position B, operator in control cab35informs operators in two loading/unloading ports5respectively stick the crane arm2and crane arm77out of the loading/unloading ports5; the operator in control cab35respectively press B1command key, falling2command keys, locking command keys, rising command key and loading/unloading position A command key to move the trolley9and sling10to B1and decline, lock and suspend the second layer of container24on the second carrying board27and move to the loading/unloading position A. After the operator in loading/unloading ports5took over the operational control, press falling command key, unlock command key, lifting command key, outward sliding command key, position B1command key, the trolley9unload container24and want back to position B1. After the container24are unload completely from the cargo carrier25to unload empty container24from container loading/unloading ports5to cargo carrier25. The sequence of unloading is the same as the sequence of unloading container24from the replenishment oiler to cargo carrier25.

The order of unloading containers24from cabin26is: first unload the three containers24in the upper layer of second row, the discharge of the order is: B1, B2, B3; and unload container24in the below layer of second row in the same order, After the second carrying board27moving the container24in front and rear rows to the second row of cabin, unload container24in the same order.

In order to strengthen the stability of container24in cabin26, we can connect the two layers of container24with controllable spin lock, the lowest layer of the container24can be connected with the second carrying board27and the bottom board of cabin26by controllable spin lock.

During the loading of three movable oil tanks48, they can be connected by communicating pipes, the total joint after connecting associated with the oil pipe7is on the movable oil tank48in the middle of cabin26. The highest speed of sailing about cargo carrier25is significantly faster than the speed of aircraft carriers and the replenishment oiler, so that we can catch the aircraft carriers and the replenishment oiler which are sailing.

In front of ring22is the display light for operation at night. Main propulsion propeller and rudder are in the rear cargo carrier25. Second rudder and second propeller for adjusting driving direction of cargo carrier's head can be put in the front of the central cargo carrier25. On both sides of the cargo carrier25are bump rubber. Cargo carrier25is designed to wave piercing catamaran, so cargo carrier25can run more stably.

In order to reduce the height of the marine lifting unit in the aircraft carrier, the fixed frames can be increased between the below of deck1of the aircraft carriers and the marine lifting unit.

There is a video camera downward on trolley9for observing the loading and unloading of container24by control cab35's operators.
