Description

Technical Field

[0001] This application relates to the field of temporary external drainage technology for large cruise ships, and in particular to a temporary drainage method and system for the construction phase of a large cruise ship. Background Technology

[0002] In the field of shipbuilding and ship drainage systems, existing technologies mainly focus on the formal drainage system after the ship is built, especially the drainage problem of specific compartments during operation (such as the bottom garage of a passenger ro-ro ship).

[0003] Existing technology discloses a dedicated drainage system for the lower-level garage of a passenger ro-ro ship. This system includes drainage ditches, a large-capacity drainage pump (first drainage pump), a small-capacity drainage pump (second drainage pump), and a complex piping network and control system. Its design aims to solve the problem of water accumulation in the lower-level garage during ship operation, such as firefighting or routine cleaning, by using a dual-pump configuration to balance drainage efficiency and energy-saving requirements under different operating conditions. This system is a formal, fixed facility on the ship, with a complex structure and high construction costs.

[0004] In the shipbuilding industry, especially during the construction of large cruise ships, the conventional solution for temporary water accumulation on open decks caused by rainwater and wash water is to use mobile diaphragm pumps for drainage. This method requires temporary power supply and water pipes and is operated manually, which results in inefficiency, manpower consumption, inconvenient equipment management, and difficulty in deployment in complex construction environments.

[0005] The construction cycle for large cruise ships is long. Furthermore, compared to indoor docks abroad, domestic outdoor docks expose open decks to the natural environment for extended periods during construction, making them highly susceptible to accumulating large amounts of wastewater due to external factors such as rainfall and washing operations. This accumulated water not only severely hinders construction safety, equipment transportation, and personnel operations, but if left for extended periods, it can also corrode hull materials, affect weld and painting quality, and even pose a potential threat to the safety of ship equipment and personnel.

[0006] Currently, the industry lacks a systematic, efficient, and low-cost solution for temporary drainage issues during the construction phase. While existing mature ship drainage systems are excellent solutions for the operational phase, they are designed for the ship's final service state. These systems are complex, expensive, and their installation spans the entire shipbuilding cycle, meaning they cannot be put into use before the ship's system is completed. Replicating such systems specifically for the construction phase would result in significant economic waste.

[0007] Traditional mobile diaphragm pump drainage solutions, while flexible, suffer from significant drawbacks such as unstable drainage efficiency, reliance on manual labor, high management costs, and particular inconvenience when operating at heights or on multiple decks. Especially in high-rise areas above the fifth deck, where construction operations frequently overlap, laying temporary drainage pipelines becomes even more difficult, making it hard to effectively implement mobile pump solutions. Summary of the Invention

[0008] This invention aims to solve the technical problem of the inability to systematically, efficiently, and cost-effectively drain accumulated water from the open decks of large cruise ships during the construction phase, which affects construction safety, project progress, and equipment safety. The embodiments of this invention creatively utilize existing resources and conditions during shipbuilding to construct a transitional, low-cost temporary drainage method, ensuring the effectiveness, reliability, and systematic nature of the drainage scheme for all open decks of the ship.

[0009] This invention provides a temporary drainage method during the construction phase of a large cruise ship, comprising: During the construction phase of large cruise ships, once the drainage system located below the fifth deck is installed, its partial drainage function is activated without waiting for the entire system to be fully completed. Identify the drainage drains distributed on the open deck, which are connected to the drainage system; Environmentally friendly green paint is used to spray the floor drains that already have drainage functions to form a green-marked area; When water accumulates on the open deck due to rain or wash water, the water naturally flows through the drains marked with green, enters the drainage network, and is eventually discharged overboard through the installed drainage pipes.

[0010] In some embodiments, the green marked area forms a prominent sign in the construction environment, making it easy for construction workers to identify and use the floor drains that have drainage functions.

[0011] In some embodiments, the environmentally friendly green paint will not cause corrosion or damage to the hull structure or equipment.

[0012] In some embodiments, the method further includes a temporary drainage step on the upper deck: For high-rise open decks with five or more decks, temporary drainage methods are adopted when construction operations are frequently overlapping and the conditions for installing formal drainage pipes are not yet mature. Connect one end of the pressure-resistant temporary hose to the floor drain on the high-rise open deck. Guide and secure the other end of the temporary hose to the green-marked floor drain on the fifth deck, so that the water accumulated on the upper deck can be diverted through the temporary hose to the floor drain on the fifth deck that has drainage function, and then discharged to the outside. After the high deck drainage system is completed, the temporary hoses will be removed and replaced with the formal drainage system.

[0013] In some embodiments, the temporary hose is a pressure-resistant hose, and the temporary hose will not cause corrosion or damage to the hull structure or equipment.

[0014] In some embodiments, the temporary hose is guided and secured to the five-deck green-marked floor drain by a fixing device to ensure a stable and reliable drainage path.

[0015] This invention provides a temporary drainage system for the construction phase of a large cruise ship, comprising: The drainage system below the fifth deck has been partially installed, including floor drains, drainage pipe network and drainage pipes; Drainage floor drains distributed on the open deck and connected to the drainage system; Environmentally friendly green paint is sprayed onto the floor drain to form a green marking area, which is used to mark the floor drain that has drainage function; When water accumulates on the open deck, it enters the drainage network through the green-marked floor drains and is discharged overboard via the installed drainage pipes.

[0016] In some embodiments, a temporary drainage system for upper decks is also included, the system comprising: A pressure-resistant temporary hose, one end of which is connected to the floor drain on the upper open deck, and the other end is guided and fixed to the green-marked floor drain on the fifth deck. The temporary hose is used to divert water accumulated on the upper deck to the drains on the fifth deck, which are already equipped with drainage functions.

[0017] In some embodiments, the temporary hose may be removed after the upper deck drainage system is completed.

[0018] In some embodiments, the green marked area forms a prominent visual marker in the construction environment, making it easy for construction workers to identify.

[0019] To overcome the shortcomings of existing technologies, the above embodiments innovatively modify the ship's existing planned system resources to solve the problem of water accumulation on open decks during cruise ship construction. This invention cleverly utilizes a portion of the ship's inherent formal external drainage system in advance, connecting certain pipelines and clearly marking the connected drains so that they can function during the construction phase. Simultaneously, differentiated drainage strategies are adopted in stages to address the construction challenges at different deck heights, accelerating the overall construction speed of the cruise ship. Through these embodiments, efficient and reliable drainage can be achieved at extremely low additional costs, ensuring the safety of equipment and personnel during construction. The above embodiments, through system optimization, reduce drainage costs. Attached Figure Description

[0022] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

[0023] In the embodiments described in this application, it should be noted that, unless otherwise stated and limited, the term "connection" should be interpreted broadly. For example, it can be an electrical connection, or a connection between two internal components. It can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0024] This patent aims to solve the technical problem that during the construction phase of large cruise ships, the accumulated water on the open decks due to rainwater and washing water cannot be systematically, efficiently, and cost-effectively drained, thus affecting construction safety, project progress, and equipment safety.

[0025] Specifically, the present invention solves the following sub-problems in the prior art: 1. The ship's inherent, efficient formal drainage system was partially installed during the middle of construction, but its function was not activated during construction and could not serve the construction process, resulting in the idleness of existing high-quality resources.

[0026] 2. In areas not covered by formal drainage systems or where construction interference is severe, relying on scattered methods such as mobile water pumps will result in low drainage efficiency, dependence on manual labor, inconvenient management, and difficulty in achieving comprehensive coverage.

[0027] 3. Designing and installing a separate temporary drainage system for a construction period that can last for several years is costly and uneconomical, while piecemeal solutions lack systematicity and reliability.

[0028] Therefore, the ultimate technical problem of this patent is: how to creatively utilize existing resources and conditions in the shipbuilding process to construct a transitional, low-cost temporary drainage method to ensure the effectiveness, reliability, and systematic nature of the drainage scheme for water accumulation on all open decks of the ship.

[0029] This invention provides a temporary drainage method during the construction phase of a large cruise ship, comprising: During the construction phase of large cruise ships, once the drainage system located below the fifth deck is installed, its partial drainage function is activated without waiting for the entire system to be fully completed. Identify the drainage drains located on the open deck, which are connected to the drainage system; Environmentally friendly green paint is used to spray the floor drains that already have drainage functions to form a green-marked area; When water accumulates on the open deck due to rain or wash water, the water naturally flows through the drains marked with green, enters the drainage network, and is eventually discharged overboard through the installed drainage pipes.

[0030] In some embodiments, the green marked area forms a prominent sign in the construction environment, making it easy for construction workers to identify and use the floor drains that have drainage functions.

[0031] In some embodiments, environmentally friendly green paint will not cause corrosion or damage to the hull structure or equipment.

[0032] In some embodiments, the method further includes a temporary drainage step on the upper deck: For high-rise open decks with five or more decks, temporary drainage methods are adopted when construction operations are frequently overlapping and the conditions for installing formal drainage pipes are not yet mature. Connect one end of the pressure-resistant temporary hose to the floor drain on the high-rise open deck. Guide and secure the other end of the temporary hose to the green-marked floor drain on the fifth deck, so that the water accumulated on the upper deck can be diverted through the temporary hose to the floor drain on the fifth deck that has drainage function, and then discharged to the outside. After the high deck drainage system is completed, the temporary hoses will be removed and replaced with the formal drainage system.

[0033] In some embodiments, the temporary hose is a pressure-resistant hose and will not cause corrosion or damage to the hull structure or equipment.

[0034] In some embodiments, the temporary hose is guided and secured to the five-deck green-marked floor drain by a fixing device to ensure a stable and reliable drainage path.

[0035] This invention provides a temporary drainage system for the construction phase of a large cruise ship, comprising: The drainage system below the fifth deck has been partially installed, including floor drains, drainage pipe network and drainage pipes; Floor drains distributed on the open deck and connected to the drainage system; Environmentally friendly green paint is sprayed onto the floor drain to form a green marking area, which is used to mark floor drains that have drainage functions. When water accumulates on the open deck, it enters the drainage network through green-marked floor drains and is discharged overboard via the installed drainage pipes.

[0036] In some embodiments, a temporary drainage system for upper decks is also included, the system comprising: A pressure-resistant temporary hose, one end of which is connected to the floor drain on the upper open deck, and the other end is guided and fixed to the green-marked floor drain on the fifth deck. Temporary hoses are used to divert water accumulated on the upper decks to the floor drains on the fifth deck, which are already equipped with drainage functions.

[0037] In some embodiments, temporary hoses may be removed after the upper deck drainage system is completed.

[0038] In some embodiments, the green marked area forms a prominent visual marker in the construction environment, making it easy for construction workers to identify.

[0039] Another embodiment of the present invention: Basic embodiment During the construction phase of large cruise ships, once the drainage system below deck five is installed, some of its functions are activated before the entire system is fully completed. Construction workers identify the drains located on the open decks, which connect to the drainage system, and paint these functional drains with environmentally friendly green paint to create green-marked areas. This marking is designed to be highly visible in the construction environment, facilitating worker identification and use. When rainwater or wash water accumulates on the open decks, it naturally flows through these green-marked drains into the drainage network, and finally drains overboard through the installed drainage pipes.

[0040] Another embodiment of the present invention: High-rise deck embodiment For high-rise open decks above the fifth deck, during periods of frequent construction overlap and when conditions are not yet ripe for installing permanent drainage pipes, the following temporary drainage method will be used: Connect one end of a pressure-resistant temporary hose to the open deck floor drain, and then guide and secure the other end of the temporary hose to the green-marked floor drain on the fifth deck. Ensure that the drainage hose will not cause corrosion or damage to the ship's structure or equipment. Once the high-rise deck drainage system is completed, the hose can be removed and the existing drainage system can be used instead.

[0041] After system optimization, the cost of drainage was reduced. According to the traditional manual drainage cost calculation, from January to October 2025, manual drainage was required four times a month, each time requiring 20 people. The cost per person per hour was 60 yuan. The final cost savings were 9*4*20*8*60=345600 (yuan).

[0042] The technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
