Description

Technical Field

[0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a method for quickly installing an LNG tank and a ship. Background Art

[0002] At present, the LNG tank compartment is composed of a saddle (directly installed on the segment), an LNG tank, etc. The saddle is scattered on multiple segments, and the LNG tank is made separately and hoisted after being made. Due to the accumulation of errors in the construction of the hull structure, the matching degree between the saddle and the tank is not high. When hoisting the tank, it is often necessary to adjust the saddle data through continuous trimming to meet the installation accuracy requirements of the tank.

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] According to a first aspect of the present invention, a method for rapid installation of an LNG tank is provided. Figure 1 and Figure 2As shown, the LNG tank 100 is installed on the saddle device 200, and a pad is provided at the bottom of the LNG tank 100, and the pad includes a first pad 11 and a second pad 12; the saddle device 200 includes a saddle, and the saddle includes a first saddle 201, a second saddle 202 and a laminated wood 23, and the first saddle 201 and the second saddle 202 have the same structure; the first saddle 201 includes a left baffle 21 and a right baffle 22, and the laminated wood 23 is installed in a first groove formed between the left baffle 21 and the right baffle 22; the first pad 11 is installed in the first groove, and the second pad 12 is installed in the second groove on the second saddle 202;

[0038] The method comprises:

[0039] Step S1: measuring data of the LNG tank 100 and measuring data of the saddle 200;

[0040] The data of measuring the LNG tank 100 includes the outer contour size data of the first cushion 11 and the second cushion 12; the data of measuring the saddle 200 includes the contour size data of the saddle; the data of measuring the LNG tank 100 also includes the distance between the first cushion 11 and the second cushion 12. Figure 4 As shown; the data of the saddle 200 specifically includes the inner contour size data of the left and right baffles of the first saddle 201 and the second saddle 202, as well as the size of the first groove and the second groove.

[0041] In some embodiments, the measurement of the saddle 200 can specifically measure the non-structural surface (inner contour surface) of the left and right baffles on the saddle, and the front and rear corresponding measurements need to be performed with one board between them, and more data points need to be collected to better complete the modeling and simulation. At the same time, in order to facilitate later adjustments, it is necessary to mark the measurement position with a paint pen.

[0042] The measurement of the LNG tank 100 specifically involves measuring the size of the wood, i.e., the skids, underneath the LNG tank;

[0043] Step S2: importing the measured data of the LNG tank 100 into the data processing software to form the first spatial data, and importing the measured data of the saddle 200 into the data processing software to form the second spatial data;

[0044] The first spatial data and the second spatial data are both spatial coordinates of multiple points collected; the second spatial data are displayed as U-shaped contour lines or points of the left and right baffles of the saddle; the first spatial data are displayed as outer contour lines or points of the pads; the contour line is formed by connecting the points, such as Figure 3As shown; in a specific embodiment, the saddle device 200 is composed of a plurality of saddles, generally the saddles appear in stacks, and a pair of saddles is used to install an LNG tank. The saddle device 200 in this embodiment includes 4 saddles, specifically a first saddle 201, a second saddle 202, a third saddle 203 and a fourth saddle 204, wherein the first saddle 201 and the second saddle 202 are a pair for installing an LNG tank, and the third saddle 203 and the fourth saddle 204 are a pair for installing another LNG tank.

[0045] Step S3: Simulate the LNG tank 100 being installed on the saddle 200, install the first spatial data on the second spatial data, and mark the distance between the pads and the left and right baffles in the saddle;

[0046] Step S4: adjusting the spacing by continuously adjusting the saddle device 200 until all spacings meet the requirements;

[0047] In step S4, when the data points of the pads are outside the inner contour of the baffle, the segmented deck where the saddle is located is adjusted, thereby adjusting the second spatial data until the data points of all the pads are within the inner contour of the baffle, that is, all the spacings meet the requirements, such as Figure 5 shown.

[0048] By simulating the installation of the LNG tank 100, the second space data is simulated with the first space data, the spacing between the wood block and the baffle is marked, and the spacing is adjusted appropriately to make as many data as possible meet the requirements. If all spacings meet the requirements, the hoisting can be successfully realized. If not, it is necessary to meet the requirements as much as possible so that the opening adjustment amount can be minimized. Figure 5 As shown, an installation position corresponding to the pad, namely, a pad installation groove 24 is provided between the left baffle plate 21 and the right baffle plate 22 . During actual installation, the pad needs to be installed in the pad installation groove 24 .

[0049] Step S5: lifting and installing the LNG tank 100 onto the saddle 200 .

[0050] According to a second aspect of the present invention, there is provided a ship, and an LNG tank on the ship is installed using the LNG tank rapid installation method described in any one of the first aspects of the embodiments.

[0051] In summary, the LNG tank quick installation method of the present application can improve the installation efficiency of the LNG tank and ensure that it is installed in place in one time; it can fully understand the conditions of the LNG tank and the saddle in advance, and then take measures in advance to avoid school closure and improve installation efficiency.

[0052] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
