Description

Technical Field

[0001] The present invention relates to the technical field of jacket loading onto ships, and specifically to an electromagnetic deep-water jacket sliding loading method onto ships. Background Art

[0002] A jacket is composed of hollow leg columns and horizontal and vertical bars connecting the leg columns. A fixed platform is lapped on it, which can be used for offshore oil exploitation. The jacket is generally built on shore and then lifted by a lifting device and moved to a loading ship. Due to the poor accuracy of the lifting device, workers are required to assist in positioning and fixing to complete the loading of the jacket onto the ship. Then, the loading ship moves the jacket to a designated sea area.

[0003] Traditional loading methods often rely on a large amount of manpower and material resources and are inefficient. At the same time, traditional transportation methods are also difficult to meet the loading requirements of high-precision equipment in terms of positioning accuracy.

[0004] In view of the above problems, an improved electromagnetic deep-water jacket sliding loading method onto ships is now designed. Summary of the Invention

[0005] The purpose of the present invention is to provide an electromagnetic deep-water jacket sliding loading method onto ships to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: An electromagnetic deep-water jacket sliding loading method onto ships includes the following steps: Step 1: Installation of the electromagnetic launching device; A fixed electromagnetic launching device is set on the dock shore to provide a strong magnetic field basis for the subsequent sliding of the jacket. Step 2: Installation of the magnetic device; The jacket is fixed on a support sliding device, and a magnetic component matching the electromagnetic launching device is installed on the support sliding device. The interaction between the magnetic component and the magnetic field generated by the electromagnetic launching device realizes effective electromagnetic drive. Step 3: System debugging and detection; The electromagnetic launching device and the magnetic component are comprehensively debugged and strictly detected to ensure the reliability and stability of the entire system and prepare for the subsequent smooth sliding loading operation of the jacket. Step 4: Initial placement of the jacket; The jacket is accurately placed on the dock shore in a predetermined direction and position. Among them, the predetermined direction is the sliding direction of the jacket, which needs to be consistent with the connection direction between the dock shore and the loading ship to ensure the accuracy of the sliding path. The predetermined position requires that the center of the magnetic component on the support sliding device be precisely aligned vertically with the center of the staggered area of the upper and lower electromagnetic coils of the electromagnetic emission device. At the same time, the center of gravity projection of the jacket must fall on the center position of the preset bearing area on the dock shore to ensure the balance and stability of the jacket during the sliding process. Support structures and positioning devices need to be set up in advance on the loading ship to provide support and guarantee for the final bearing and positioning of the jacket; Step Five: Start the electromagnetic drive and process monitoring; Start the electromagnetic emission device. By precisely controlling the magnitude and direction of the current in the electromagnetic coils, flexibly adjust the generated magnetic field strength and direction, thereby driving the support sliding device at the bottom of the jacket, and then pushing the entire jacket to slide towards the loading ship at a speed of 0.05 m / s. During the entire sliding process, the position, speed, and attitude of the jacket are monitored in real time through sensors installed on the jacket, and the parameters of the electromagnetic emission device are adjusted in a timely manner based on the monitoring data to ensure that the sliding process of the jacket is safe, stable, and meets expectations; Step Six: Operations after the loading is completed; When the jacket slides to the predetermined position on the loading ship, stop the electromagnetic emission device. At this time, the support structure on the loading ship will bear the weight of the jacket, completing the loading operation of the jacket.

[0007] As a further solution of the present invention: The electromagnetic emission device includes a plurality of high-power electromagnetic coils, and these electromagnetic coils are arranged in a layered and staggered manner. Specifically, upper and lower layers of electromagnetic coils are set. Among them, the upper-layer electromagnetic coils are arranged horizontally at equal intervals, while the lower-layer electromagnetic coils are arranged at equal intervals in a direction perpendicular to the upper layer and are staggered with the upper-layer electromagnetic coils. Such an arrangement can form a unique magnetic field distribution.

[0008] As a still further solution of the present invention: The electromagnetic emission device includes a fixing plate. At the lower end of the fixing plate, a plurality of support seats for supporting the fixing plate are installed. The support seats are fixedly installed on the dock shore. A plurality of columns of first electromagnetic coils are vertically installed at the upper end of the fixing plate, and the plurality of columns of first electromagnetic coils are arranged horizontally at equal intervals. Second electromagnetic coils are installed on the fixing plate between adjacent two columns of first electromagnetic coils. Second limit support frames are installed on both sides of the fixing plate.

[0009] As a further solution of the present invention: The support sliding device includes a sliding plate and a plurality of pipe clamps. The jacket is fixed to the upper end of the sliding plate through the pipe clamps. A magnetic component that cooperates with the first electromagnetic coil and the second electromagnetic coil is installed on the side of the lower end of the sliding plate away from the loading ship. The magnetic component is arranged between two adjacent first electromagnetic coils. Limit sliding plates that cooperate with the second limit support frame are installed on both sides of the lower end of the sliding plate. The limit sliding plates are slidably connected to the inner wall of the second limit support frame. A first limit support frame that cooperates with the limit sliding plates is installed on the loading ship.

[0010] As a further solution of the present invention: The magnetic component is made of a material with high magnetic permeability, and this material property helps to enhance the interaction between it and the magnetic field generated by the electromagnetic emission device.

[0011] As a further solution of the present invention: A guiding plate for facilitating the sliding of the limit sliding plate onto the first limit support frame is installed at one end of the limit sliding plate close to the loading ship.

[0012] As a further solution of the present invention: Ball bearings for facilitating the sliding of the limit sliding plates are installed on the inner walls of the second limit support frame and the first limit support frame.

[0013] As a further solution of the present invention: The number and arrangement of the electromagnetic coils in the electromagnetic emission device are adjusted according to the weight, size, and shape of the jacket, and the number and installation positions of the magnetic devices are optimized according to the structural characteristics of the bottom support flat plate of the jacket.

[0014] As a further solution of the present invention: During the sliding process, the electromagnetic emission device continuously operates to generate a driving magnetic force to push the jacket towards the transport ship. When loading onto the ship according to a preset program, during the process of the jacket approaching the predetermined position of the transport ship, continuous power supply is carried out, and the current is gradually reduced, so that the speed of the jacket moving towards the designated position of the transport ship is gradually reduced until the speed is zero.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The present invention uses the electromagnetic drive and emission method to move the jacket onto the loading ship, realizing the streamlined operation of deep-water jacket terminal loading and transportation, greatly reducing its loading and transshipment costs, and improving the loading and transportation efficiency of the jacket.
