A floating liquefied natural gas production storage and offloading (FPSO) is a floating lng processing platform, which is generally designed as a ship-type structure and is equipped with equipment such as a natural gas liquefaction plant and an lng storage tank. FPSOs generally have no self-navigation capability, need to tow to reach appointed sea area through the tow boat in the process of transferring, tow cost and tow risk are great. And the FPSO is additionally provided with a fixed propelling device, so that the idling rate is high, the space of the ship body is occupied, and the economy is poor. Therefore, the FPSO is provided with the detachable propeller, the propeller is only rapidly installed on the ship body when the FPSO is shifted, the ship body power station matching through the FPSO completes self-navigation shifting, the transportation cost is greatly saved, and the shifting risk of the FPSO is reduced. The detachable propeller is a complete set of propulsion system, and mainly comprises a propeller arranged outside a ship body, and a propulsion motor, a steering mechanism, a control system, an electric power system and the like which are arranged in the ship body. Because removable propeller has advantages such as the integrated level is high, small, easy dismounting, removable propeller more and more obtains industry approval, especially on standardized, general type's floating device, application prospect is wide.
The mounting and dismounting is one of the key links for the successful application of the detachable thruster. The existing dismounting method comprises the following steps: the propeller is installed underwater outside the hull with the aid of an engineering vessel equipped with a crane. The propulsion equipment in the ship body is lifted one by arranging a lifting opening on an open deck of the ship body and depending on an engineering ship with a deck crane or a crane. The following insufficiencies of current hull when carrying out the detachable propeller dismouting: (1) the object lifting opening needs to be reserved on the weather deck, precious deck space is occupied, weather deck equipment is extruded, and inconvenience is brought to later-stage use of main deck equipment. (2) The equipment needs to be provided with a heavy crane on the deck, so that the utilization rate of the crane is low, and resources are wasted; or renting an external engineering ship to assist the FPSO in hoisting the propelling equipment in and out. The renting engineering ship needs advance reservation and ship scheduling, and has high cost and poor economical efficiency.

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 1 and 2, for the ship disclosed in this embodiment, the ship includes a hull 100 and an equipment bin disposed inside the hull 100, an opening is disposed at an upper end of a stern sealing plate 101 of the hull 100, a conveying channel is disposed between the opening and the equipment bin, a guide rail 3 is disposed at an inner top of the conveying channel, the guide rail 3 extends from above the equipment bin toward the opening and extends out of the opening, and a hoisting mechanism is disposed on the guide rail 3.
The opening for entering the equipment bin is formed in the stern sealing plate 101 of the ship body 100, and the propulsion equipment of the propeller is conveyed to the equipment bin below the main deck 103 through the hoisting mechanism, so that the method that a hoisting port needs to be reserved in the main deck 103 in the traditional hoisting mode is changed, precious deck space is not occupied, the equipment arrangement of the main deck 103 is not extruded, a heavy crane or an external engineering ship does not need to be arranged on the deck, and the cost is effectively reduced.
In this embodiment, in order to prevent the hoisted object from colliding with the stern sealing plate 101 during hoisting and damaging the stern sealing plate 101, one end of the guide rail 3 extends out of the opening and is far away from the stern sealing plate 101.
The opening is provided with a sealing door 6, and the sealing door 6 can seal the opening. Since the opening needs to be sealed, the guide rail 3 of the hoisting mechanism can be blocked, therefore, in this embodiment, as shown in fig. 1-2, there are two hoisting mechanisms, namely a first hoisting mechanism 4 and a second hoisting mechanism 5, which are respectively located at two sides of the opening, the first hoisting mechanism 4 is arranged at the outer side of the opening, and the second hoisting mechanism 5 is arranged at the inner side of the opening. The opening is conveniently sealed after the hoisting is completed, and external water is prevented from entering the hull 100.
Of course, in other embodiments, only one hoisting mechanism may be provided, but other auxiliary mechanisms need to be added, for example, the hoisting mechanism is arranged inside the opening, the reversing wheel is arranged outside the opening, and the lifting hook is retracted into the opening after hoisting is completed.
In the present embodiment, as shown in fig. 1, the transfer passage includes a first passage 1 and a second passage 2 communicating with each other, and the hull 100 includes a main deck 103 disposed uppermost on the hull 100 and an inner deck 104 disposed below the main deck 103; the first passageway 1 is provided between the main deck 103 and the inner deck 104, and the second passageway 2 extends downward in the height direction of the hull 100 from below the main deck 103, and communicates with the equipment compartment through the inner deck 104.

The cable duct 8 facilitates the extension and retraction of the cable 9 of the cable mechanism, prevents friction between the cable 9 and the inner deck 104, and prevents external water from entering the inner deck 104. After the propeller is installed or removed, the messenger pipe 8 may be sealed to further prevent water from entering the hull 100 from the messenger pipe 8.
In this embodiment, the opening is further provided with a platform 7, and the platform 7 is fixed on the stern sealing plate 101 and located between the two hoisting mechanisms. The object placing table 7 is arranged so as to temporarily place and transport lifting objects and facilitate command of personnel. Wherein, the upper surface of the object placing table 7 is not lower than the upper surface of the inner deck 104. This is to prevent the sling from colliding with the inner deck 104 when the sling is transported.
