Description

Technical Field

[0001] This invention relates to a process for transporting and installing a podded propulsion device. Background Technology

[0002] Currently, Haida's intelligent dual-purpose vessel is equipped with two podded propellers at its stern. These propellers offer excellent maneuverability, allowing for 360-degree rotation and flexible control of the vessel's course and thrust, enabling forward, turning, translation, and reversing maneuvers. Conventional azimuth propellers, after being manufactured by the equipment manufacturer, are transported lying down or using a fairing as a support base. Upon arrival at the factory, they are lifted and turned upright using a crane on the slipway. Then, from the stern or side, a crane, along with a hand-operated hoist, moves them into the hull and lifts them upwards from the bottom of the vessel for installation. This installation method is time-consuming with the slipway cranes, involves a long construction cycle using hand-operated hoists, requires multiple personnel, and poses significant safety risks. To address these construction issues, a new process for transporting and installing podded propellers has been researched and invented. Summary of the Invention

[0003] The purpose of this invention is to provide a process for transporting and installing podded propulsion devices that saves storage space and improves construction efficiency.

[0004] The technical solution adopted by the present invention to achieve the above objectives is: a process method for transporting and installing a podded propulsion device, comprising the following steps: a. The podded thruster is normally lifted and placed on the transport base, and then fixed in place by bolts. The thruster is fixed to the transport base to form a single unit; b. Transfer the propulsion unit and transport base as a whole to the transport barge, and use sealing ropes to secure the transport base to the transport barge; c. After the transport barge arrives at the shipyard by sea, the sealing ropes are removed, and the propeller and transport base are unloaded onto the dock. d. Use a forklift to move the pusher and transport base as a whole to the designated installation position on the slipway; e. Install temporary eyeboards in advance in the outer plating area of ​​the ship, and hang the hand chain hoists used for lifting and adjustment on the temporary eyeboards in advance; f. Use a hand-operated hoist to connect the lifting points on the pusher. Before lifting, remove the detachable lifting points on the top of the pusher and remove the fixing devices between the pusher and the transport base. g. Use a hand-operated hoist mounted on the outer plate to lift the propeller and adjust the installation angle so that it is basically close to the angle of the ship's base; h. Personnel enter the thruster compartment to clean and apply adhesive to the sealing surfaces to ensure the equipment is sealed after installation. Fixing bolts are installed in the thruster compartment and pre-tightened until they fit the sealing surfaces, thus completing the thruster installation.

[0005] In step a, the transport base is provided with forklift holes, lifting points, and eye plates for connecting sealing ropes.

[0006] In step b, the propeller and transport base are transported as a whole onto the transport barge using a forklift or crane.

[0007] In step f, the detachable lifting point of the top bolt connection of the thruster is fixed to the equipment flange by bolts.

[0008] This invention provides a process for transporting and installing podded propulsion devices, which solves the problem of long construction cycles for propulsion device installation on slipways, reduces equipment slipway installation time, and improves construction efficiency.

[0012] like Figures 1 to 3As shown, the process for transporting and installing the podded propulsion unit includes the following steps: a) The podded propulsion unit 1 is normally lifted and placed on the transport base 2. The propulsion unit 1 is fixed to the transport base 2 as a whole by bolts connecting the fixing device 3. The transport base 2 is provided with forklift holes, lifting points, and eye plates for connecting sealing ropes; b) The propulsion unit 1 and the transport base 2 are transported as a whole to the transport barge using a forklift or crane. The transport base 2 is then sealed to the transport barge using sealing ropes 4; c) After the transport barge is transported to the shipyard, the sealing ropes 4 are removed, and the propulsion unit 1 and the transport base 2 are unloaded onto the dock; d) The propulsion unit 1 and the transport base 2 are transported as a whole to the designated installation position on the slipway 10 using a forklift; e) In advance, the propulsion unit 1 is transported to the designated installation position on the ship 5. A temporary eyeplate 6 is installed in the plate area, and the hand-operated hoist 7 for lifting and adjustment is pre-installed on the temporary eyeplate 6; f. The hand-operated hoist 7 is used to connect the lifting point 8 on the thruster 1. Before lifting, the detachable lifting point 9 on the top of the thruster 1 is removed, and the fixing device 3 between the thruster 1 and the transport base 2 is removed. The detachable lifting point 9, which is bolted to the top of the thruster, is fixed to the equipment flange with bolts; g. The hand-operated hoist 7, which is installed on the outer plate, is used to lift the thruster 1 and adjust the installation angle so that it is basically close to the angle of the ship 5 base; h. Personnel enter the thruster compartment to clean and apply adhesive to the sealing surface to ensure the sealing state after the equipment is installed. The fixing bolts are installed in the thruster compartment and pre-tightened until the sealing surface is in contact, thus completing the installation of the thruster 1. The process method for transporting and installing the podded thruster of the present invention allows the thruster to be transported normally, saving storage space. Forklifts can be used for relocation, avoiding the occupation of the shipyard crane. Two thrusters can be installed at the same time, solving the problem of long construction cycle for thruster installation on the shipyard, reducing the equipment installation time on the shipyard, and improving construction efficiency.
