Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method for mounting a PCTC ship and the ship itself. Background Technology

[0002] As a core infrastructure for shipbuilding, repair, and conversion, the utilization rate of dry docks directly determines the capacity efficiency and economic benefits of the shipping and shipbuilding industries. In related technologies, PCTC (Portable Containerized Tractor) vessels are built entirely in dry docks, with a dry dock cycle of up to 150 days. After assembly, the entire vessel is unloaded. The long dry dock construction cycle for PCTC vessels results in a low annual production volume for mass-produced dry docks. Summary of the Invention

[0003] The purpose of this invention is to provide a method for loading PCTC ships and a ship, thereby shortening the loading cycle in the dry dock and increasing the annual output of shipbuilding.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A method for launching PCTC (Potentially Targeted Taxi) vessels, comprising:

[0006] The PCTC vessel is divided into a first half-ship and a second half-ship, with the first half-ship located below the second half-ship.

[0007] The first half of the first vessel was built on the platform line, while the second vessel was built in the dry dock.

[0008] The first half of the first vessel was launched and submerged by a semi-submersible vessel.

[0009] The second vessel was completed and launched from the dry dock.

[0010] The first half of the first vessel was towed into the dock.

[0011] The first half of the vessel continues to be constructed by mounting the second half of the vessel on the upper section of the first half of the vessel.

[0012] The first vessel was completed in the dry dock and then launched.

[0013] In some embodiments, when dividing the PCTC vessel, it is ensured that the weight of the first half-vessel is less than the maximum lift of the semi-submersible vessel launched below the platform.

[0014] In some embodiments, the launching time of the first half of the first vessel on the platform line is matched with the docking time of the second vessel in the dock, so that the first half of the first vessel can enter the dock immediately after being launched.

[0015] In some embodiments, when the first half of the first vessel completes its launching and submersion by a semi-submersible vessel, the following steps are included:

[0016] The semi-submersible vessel is moored and secured at the dock.

[0017] The first half of the first vessel was transported to the semi-submersible vessel using a transport trolley.

[0018] The semi-submersible vessel is towed to the deep waters of the harbor basin and submerged, and the first half of the first vessel rises and leaves the semi-submersible vessel.

[0019] In some embodiments, towing the first half of the first vessel into the dry dock includes the following steps:

[0020] The first half of the first vessel was towed into the dock using a tugboat.

[0021] The position of the first half of the first vessel is adjusted using the cable in the dock so that the position of the first half of the first vessel matches the position of the dock pier in the dock that has been arranged.

[0022] The dock is pumped out, and the first half of the first vessel is placed on the pier.

[0023] In some embodiments, the first vessel and the second vessel are of the same type of hull, or the first vessel and the second vessel are of different types of hull.

[0024] In some embodiments, when the first half of the first vessel is launched and submerged by a semi-submersible vessel, the following step is further included: the construction of the third vessel's half is carried out on a platform line.

[0025] In some embodiments, after the first vessel is fully constructed in the dock and leaves the dock, the following step is further included: half of the third vessel is towed into the dock.

[0026] In some embodiments, the first vessel and the third vessel are of the same type of hull, or the first vessel and the third vessel are of different types of hull.

[0027] A vessel is formed by loading a PCTC vessel using the loading method described in any of the preceding claims.

[0028] In one embodiment,

[0029] The beneficial effects of this invention are:

[0030] By dividing the PCTC vessel into a first half-ship and a second half-ship, and by setting up a platform line and a dry dock, the first half-ship of the first vessel is built on the platform line, while the second vessel is built on the dry dock. The platform line and the dry dock are linked, allowing for simultaneous construction of different vessels, i.e., the first and second vessels, thereby shortening the overall dry dock cycle and increasing the annual shipbuilding output. Because the first half-ship of the first vessel is built on the platform line, the dry dock construction cycle is shortened, thus increasing the annual shipbuilding output.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 10 As shown, the present invention provides a method for launching a PCTC vessel, comprising the following steps:

[0048] S100, the PCTC vessel is divided into the first half-ship 110 and the second half-ship 120, with the first half-ship 110 located below the second half-ship 120;

[0049] S200 and the first half of the first vessel 100, 110, are being built on platform line 700, while the second vessel 200 is being built on dock 800.

[0050] S300, the first half of the first vessel 100 110 was launched and submerged by the semi-submersible vessel 500;

[0051] S400, the second vessel 200 completed the entire ship leaving the dry dock 800;

[0052] S500, tow the first half of the first vessel 100, 110, into the dry dock 800;

[0053] S600, the first half of the first vessel 100, the upper section of the first half of the vessel 110 continues to support the construction of the second half of the vessel 120;

[0054] The first vessel, S700, was completed in dry dock 800 and then launched.

[0055] By setting up platform line 700 and dry dock 800, the first half-ship 110 of the first vessel 100 is built on platform line 700, while the second vessel 200 is built on dry dock 800. Platform line 700 and dry dock 800 are linked, allowing for the simultaneous construction of different vessels, namely the first vessel 100 and the second vessel 200, thereby shortening the overall dry dock 800 construction cycle and increasing the annual shipbuilding output. Because the first half-ship 110 of the first vessel 100 is built on platform line 700, the construction cycle on dry dock 800 is shortened, thus increasing the annual shipbuilding output.

[0056] In step S100, when dividing the PCTC vessel, ensure that the weight of the first half-ship 110 is less than the maximum lift capacity of the semi-submersible vessel 500 launched from platform line 700. The maximum lift capacity of the semi-submersible vessel 500 refers to the maximum weight of cargo that the semi-submersible vessel 500 can bear and lift after adjusting the ballast water to submerge the main deck to a certain depth, allowing the cargo to float onto the loading deck and be lifted. The unit is usually tons. It is an important indicator of the semi-submersible vessel 500's carrying capacity. The semi-submersible vessel 500 works by controlling the hull's buoyancy by filling or emptying the ballast tanks. When cargo needs to be loaded, the semi-submersible vessel 500 fills the ballast tanks with water, causing the main deck to sink underwater, allowing the cargo to float above the main deck. Then, the semi-submersible vessel 500 drains the water from the ballast tanks, causing the main deck to rise, lifting and securing the cargo, thus achieving cargo transportation. For example, the semi-submersible vessel 500 has a maximum lifting capacity of 100,000 tons, meaning it can lift cargo weighing no more than 100,000 tons. Therefore, the weight of the first semi-submersible vessel 110 does not exceed 100,000 tons. The specific weight of the first semi-submersible vessel 110 and the PCTC vessel classification method are adaptively designed based on the maximum lifting capacity of the semi-submersible vessel 500. In one embodiment, such as... Figure 2 and Figure 3 As shown, the first vessel 100 has 13 decks, a bridge deck, and a compass deck. The area with 5 decks or less is the first half-ship 110, and the rest is the second half-ship 120.

[0057] In one embodiment, during steps S300 and S400, the launching time of the first half-ship 110 of the first vessel 100 on platform line 700 is matched with the departure time of the second vessel 200 from dock 800, ensuring that the first half-ship 110 of the first vessel 100 can immediately enter dock 800 after launching. By rationally arranging the production plan, the first half-ship 110 of the first vessel 100 is immediately brought into dock 800 after the second vessel 200 leaves dock 800, ensuring full utilization of dock 800, preventing idleness, and thus improving utilization rate, thereby increasing the annual output of shipbuilding.

[0058] In step S300, the following steps are included:

[0059] The semi-submersible vessel 500 is moored and secured at the dock.

[0060] Use a transport trolley to transport the first half of the first vessel 100, 110, onto the semi-submersible vessel 500.

[0061] The semi-submersible vessel 500 was towed to the deep water of the harbor basin and submerged, while the first half of the vessel 100, hull number 110, floated away from the semi-submersible vessel 500. Specifically, after the semi-submersible vessel 500 docked at the pier, it was secured by mooring to ensure its stability and reliability. Furthermore, this included preparing for loading and conducting a comprehensive inspection of the semi-submersible vessel 500's ballast water system, navigation equipment, communication equipment, etc., to ensure their normal operation.

[0062] In step S500, the following steps are included: using a tugboat to tow the first half-ship 110 of the first vessel 100 into the dock 800, making it convenient for the first half-ship 110 to enter the dock 800 and facilitating operation; using the cable in the dock 800 to adjust the position of the first half-ship 110 of the first vessel 100 so that the first half-ship 110 of the first vessel 100 matches the position of the dock piers already arranged in the dock 800; the dock 800 is pumped out, and the first half-ship 110 of the first vessel 100 sits on the piers, improving operational efficiency.

[0063] In one embodiment, the first vessel 100 and the second vessel 200 are of the same type. The first half-ship 110 of the first vessel 100 is constructed on platform line 700, while the second half-ship 120 of the second vessel 200 is constructed on dock 800, so that the half-ships can be placed on the dock in situ, avoiding the need for rearranging the dock piers. In addition, when the PCTC vessel is divided into the first half-ship 110 and the second half-ship 120 in step S100, the division can be made by referring to the calculation of the construction time of the first half-ship 110 and the second half-ship 120, so as to match the launching time of the first half-ship 110 of the first vessel 100 on platform line 700 with the unloading time of the second vessel 200 on dock 800.

[0064] When the first half-ship 110 of the first vessel 100 completes its launching and submersion via the semi-submersible vessel 500, the following steps are also included:

[0065] The third vessel's half-ship 310 was built on platform line 700, which made full use of platform line 700, prevented it from being idle, and thus improved utilization rate, thereby increasing the annual output of shipbuilding.

[0066] The first vessel, 100 units, was completed in dry dock 800. After the vessel was undocking, the following steps were also included:

[0067] The third vessel's half-ship, 310, was towed into dry dock 800. By rationally arranging the production plan, the first half-ship, 110, of the third vessel was immediately brought into dry dock 800 after the first vessel, 100, left dry dock 800. This ensured that dry dock 800 was fully utilized, preventing idleness and thus improving utilization rate, thereby increasing the annual output of shipbuilding.

[0068] Optionally, the first vessel 100 and the third vessel are of the same type of hull, so that the half-ship can be placed on the dock in its original position, avoiding the need for rearranging the dock piers. When the first half-ship 110 of the third vessel is launched and submerged by the semi-submersible vessel 500, the following steps are also included: the half-ship of the fourth vessel is carried out on the platform line 700, and the above steps are repeated to carry out the construction of more vessels.

[0069] Optionally, the first vessel 100 and the second vessel 200 may be of different hull types, and the first vessel 100 and the third vessel may be of different hull types, so as to achieve the simultaneous construction of different vessels.

[0070] Optionally, both Platform Line 700 and Dock 800 can simultaneously construct two or more hulls, further improving efficiency.

[0071] Optionally, an assembly area 900 is located between dry dock 800 and platform line 700. This area is specifically for the assembly of ship sections. In some large shipbuilding projects, a large assembly area 900 is used to assemble the various sections into larger sections, which are then transported to dry dock 800 or the slipway for final assembly. In addition, the assembly area may also include pre-assembly areas for the pre-installation and commissioning of ship equipment and systems. The assembly area 900 is located between dry dock 800 and platform line 700, facilitating docking with both dry dock 800 and platform line 700 respectively, thus improving operational efficiency.

[0072] The specific operational methods for the construction and launching of the first half-ship 110, the construction of the second half-ship 120, the submersion of the first half-ship 110 and the semi-submersible vessel 500, the towing of the first half-ship 110 into the dry dock and its placement on the pier, etc., can all refer to existing technologies and will not be elaborated further.

[0073] This embodiment also provides a vessel that is assembled using the PCTC vessel assembly method described above.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
