Description

Technical Field

[0001] The invention belongs to the technical field of ship engine room pre-outfitting, in particular to a finished oil and chemical ship engine room pre-outfitting process. Background Art

[0002] Finished oil and chemical tankers are mainly used to transport bulk oil, finished oil, petroleum products, petrochemicals, chemical synthetic products, animal and vegetable oils and other liquid cargoes. They usually have structural features such as double bottom, double side, and continuous main deck to ensure safety and stability during transportation. Before the pre-outfitting of the engine room of a finished oil or chemical tanker, the hull is regarded as a carrier, and all objects installed on the hull are called outfitting parts. The inner meaning of outfitting to achieve efficient shipbuilding should be "outfitting first", that is, to reduce the amount of outfitting work in the ship during docking and launching to a minimum, to move the outfitting process forward or optimize the daily process, to maximize the completion rate of each production link, and to achieve prefabrication and preinstallation.

[0003] At present, during the pre-outfitting process of the ship's engine room, some problems in the installation process may be exposed during the actual installation process, so that the verification of the solutions to these problems may need to be carried out during the actual installation process, which not only increases the risk, but may also affect the entire construction cycle, increase the difficulty and time cost of rectification, and affect the efficiency of pre-outfitting of the engine room of finished oil and chemical ships and the ship construction cycle.

[0004] Therefore, we propose a pre-outfitting process for the engine room of finished oil and chemical tankers. Summary of the invention

[0005] The purpose of the present invention is to provide a pre-outfitting process for the engine room of a finished oil or chemical ship in order to discover and solve problems in the installation process in advance, thereby improving the pre-outfitting rate and shortening the ship construction period.

[0006] The technical solution adopted by the present invention is as follows: A pre-outfitting process for the engine room of a finished oil and chemical tanker, including ship outfitting simulation, block pre-outfitting, block pre-outfitting, engine room equipment pre-installation, piping and cable laying, outfitting parts inspection and commissioning, and ship painting and anti-corrosion; The steps of the ship outfitting simulation are: S1: Use 3D modeling software to build a 3D model of the ship's engine room and reflect all the structures, equipment, pipelines, and cable elements in the engine room; S2: Perform information integration, integrate equipment parameters, installation locations, connection methods, and material specifications into the model, and attach all information required for design, production, and construction to the model through attributes or tags; S3: Perform collision detection. Use the collision detection function of the 3D model to check the spatial relationship between equipment, pipes, cables, etc. to avoid interference and conflict during installation. Adjust the model and optimize the layout to ensure that all elements can be installed smoothly. S4: Carry out pre-outfitting planning, plan the order and steps of pre-outfitting in the model, and determine the pre-outfitting content of each section and the whole section; S5: Use the dynamic simulation function of the model to simulate the entire process of pre-outfitting, including equipment hoisting, pipeline connection, and cable laying; through simulated construction, identify potential problems and risks, and take preventive and corrective measures in advance.

[0007] In a preferred embodiment of the invention, the segmented pre-outfitting includes installing piping, cables and equipment mounts on the segmented structure to ensure that all outfitting parts fit tightly with the segmented structure without any omissions or incorrect installations.

[0008] In a preferred embodiment of the invention, the overall section pre-outfitting includes the main engine, auxiliary engine, pump body, piping, cables, lamp rack and control box, and multiple segment structures are combined to form the overall section.

[0009] In a preferred embodiment of the invention, the pump body includes a lubricating oil pump, a fuel oil pump, a seawater pump, a fresh water pump, a cargo oil pump and a sewage pump.

[0010] In a preferred embodiment of the invention, the piping system includes large-diameter pipes for a seawater system, a bilge water system, a ballast system, and a fuel and lubricating oil system.

[0011] In a preferred embodiment of the invention, the engine room equipment pre-installation is used to pre-install the engine, shaft system, boiler and oil separator in the engine room, ensuring that the equipment is accurately positioned and does not interfere with the surrounding structures, laying the foundation for subsequent installation and commissioning.

[0012] In a preferred embodiment of the invention, the piping and cable laying includes laying pipes for the fuel system, cooling system, drainage system, and cables for transmitting from the generator to various equipment on the ship, ensuring that the piping and cables are laid in a reasonable direction, firmly fixed, and avoiding conflicts with other components.

[0013] In a preferred embodiment of the invention, the inspection and debugging of outfitting parts includes inspecting all pre-installed outfitting parts to ensure that they are installed correctly without damage or omission, and performing preliminary debugging on parts that need debugging to ensure that they function normally.

[0014] In a preferred embodiment of the invention, the ship painting and anti-corrosion treatment includes painting and anti-corrosion treatment of the pre-outfitting area to protect the outfitting parts from corrosion and damage.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1.
