A kind of installation method of propulsion equipment and propeller of ship, propeller

Abstract

The invention discloses a ship, a propulsion device of a propeller and an installation method of a propeller. The ship includes a ship body and an equipment compartment arranged inside the ship body. The upper end of the stern seal plate of the ship body is provided with an opening. There is a conveying channel between the equipment compartment, and a guide rail is provided on the inner top of the transport channel, and the guide rail extends from above the equipment compartment toward the direction of the opening and protrudes out of the opening, and the guide rail There is a hoisting mechanism on it. In the present invention, an opening for entering the equipment compartment is set on the stern seal plate of the hull, and the propulsion equipment of the thruster is transported to the equipment compartment under the main deck through the hoisting mechanism, which changes the traditional hoisting mode that needs to be reserved on the main deck. The method of lifting objects will not take up valuable deck space and squeeze the main deck equipment layout, and there is no need to set up heavy cranes on the deck or rent external engineering ships, which effectively reduces costs.

Description

technical field [0001] The invention relates to a ship, propulsion equipment of a propeller and an installation method of a propeller. Background technique [0002] Floating liquefied natural gas production, storage and offloading unit (FPSO) is a floating liquefied natural gas processing platform, usually designed as a ship-shaped structure, equipped with natural gas liquefaction equipment and liquefied natural gas storage tanks and other equipment. FPSO generally has no self-propelled capability, and needs to be towed by tugboats to reach the designated sea area during the transfer process, and the cost and risk of towage are relatively high. However, adding a fixed propulsion device to the FPSO has a high idle rate and takes up space in the hull, which is poor in economy. Therefore, the FPSO is equipped with a detachable propeller, and the propeller is only quickly installed on the hull when the FPSO is displaced, and the self-propelled displacement is completed through ...

AI Technical Summary

Problems solved by technology

The existing hull has the following disadvantages when disassembling and assembling the detachable propeller: (1) It is necessary to reserve a lifting port on the open deck, which takes up valuable deck space and squeezes the equipment layout on the open deck, which brings great inconvenience to the later use of the main deck equipment. inconvenient

(2) Heavy-duty cranes need to be installed on the deck for equipment hoisting out. This crane has a low utilization rate and wastes resources; or rent an external engineering ship to assist the FPSO to hoist the propulsion equipment in and out

It is usually necessary to make an appointment in advance to arrange a ship schedule when renting an engineering ship, which is expensive and economical
