[0002] Liquefied natural gas (LNG), widely used in industry and daily life, is widely recognized as the cleanest fossil energy source on Earth. Its importance and potential are increasingly recognized. Long-distance transportation of LNG requires LNG carriers. The MARK III containment system is a type of LNG containment system. In the marine industry, it is primarily used in the construction of LNG carrier cargo tanks and LNG fuel tank containment systems. This containment system carries LNG at -163°C and offers advantages such as easy installation and high efficiency.

[0003] During the construction of LNG cargo and fuel tanks, a containment system installation platform is required to support the construction of the containment system. The base of this platform features several support legs, which rest upon the insulation modules after installation. The insulation modules of the MARK III containment system are designed to withstand a pressure of 2 bar under normal conditions and 3.5 bar under extreme conditions. To verify the stress on the insulation modules beneath the support legs, force measurements are performed on each support leg after installation. Summary of the Invention

[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a force measuring device for the support legs of the installation platform of the MARKⅢ type enclosure system. Figure 1 、 Figure 2 A force measuring device for the support leg of a MARKⅢ type enclosure system installation platform includes a support base plate 1, a main beam 2 is vertically arranged above the support base plate 1, and the support base plate 1 and the main beam 2 are relatively connected and supported by a support assembly 3, and a plurality of support assemblies 3 are arranged between the main beam 2 and the support base plate 1.

[0033] The support assembly 3 includes a support leg 31, which is vertically arranged. A spacer support 32 is provided below the support leg 31. The spacer support 32 and the support leg 31 jointly support the main beam 2. The top of the spacer support 32 has a threaded hole, and the bottom of the support leg 31 is fixedly connected to the spacer support 32 by a bolt. The bolt extends through the threaded hole and is threadedly connected to the spacer support 32.

[0034] The support leg 31 includes a main body 311 and a lifting part 312 located at the bottom end. The lifting part 312 is threadedly connected to the main body 311. By rotating the lifting part 312, the lifting part 312 can be driven to move along the height direction inside the main body 311 to adjust the height of the entire support leg 31.

[0035] When force measurement is required on the support leg 31, the support leg 31 is separated from the spacer support 32, that is, the bolts between the support leg 31 and the spacer support 32 are removed. Jacks 33 are provided on both sides of the support leg 31. In some embodiments, two jacks 33 are provided, and the two jacks 33 are symmetrically arranged around the support leg 31.

[0036] The jack 33 is used to temporarily support the main beam 2 to facilitate separation of the support leg 31 from the spacer support 32. A pressure sensor 4 is positioned between the support leg 31 and the spacer support 32 to measure the pressure on the support leg 31. In some embodiments, the top of the jack 33 abuts the bottom wall of the main beam 2, while the bottom of the jack 33 abuts the top wall of the support base 1. The maximum height of the jack 33 is greater than the combined height of the support leg 31, pressure sensor 4, and spacer support 32, thereby facilitating installation of the pressure sensor 4.

[0037] In some other embodiments, an extension rod 34 is vertically arranged at the top of the jack 33, the extension rod 34 is fixedly connected to the top of the jack 33, and the top of the extension rod 34 abuts against the bottom wall of the main beam 2, and the bottom end of the extension rod 34 is connected to the top of the jack 33, so that the main beam 2 is supported by the jack 33 and the extension rod 34.

[0038] A display is also provided on one side of the pressure sensor 4 . The display is connected to the pressure sensor 4 signal and is used to display the pressure value detected by the pressure sensor 4 .

[0039] When the pressure sensor 4 is placed between the support leg 31 and the spacer support 32, the jacks 33 on both sides are removed so that the support leg 31 fully supports the main beam 2, thereby measuring the force of the support leg 31 at this time through the pressure sensor 4. After the measurement is completed, the jack 33 is reinstalled between the main beam 2 and the support base plate 1, and supported by the jack 33, which facilitates the later disassembly and assembly of the pressure sensor 4.

[0040] The present application also discloses a measurement method, which is applied to the force measuring device of the support leg 31 of the MARKⅢ type enclosure system installation platform. Figure 1-Figure 3 , measurement methods include:

[0041] S01: Measure the distance H between the bottom end of the main beam 2 and the bottom end of the supporting base plate 1. Place two sets of jacks 33 and extension rods 34 on both sides of the supporting legs 31. Raise the two jacks 33 at the same time to unload the load on the supporting legs 31. At this time, the height of the main beam 2 is greater than H.

[0042] S02: Rotate the adjusting bolt under the support leg 31 to create a gap between the bottom end of the support leg 31 and the spacer support 32, and place the pressure sensor 4 between the support leg 31 and the spacer support 32;

[0043] S03: Turn the bolts at the bottom of the support leg 31 so that the support leg 31 contacts the sensor. At this time, the height of the main beam 2 is greater than H. Lower the height of the jack 33, unload the jack 33, remove the jack 33 and the extension rod 34, and the height of the main beam 2 returns to H. Record the reading on the display connected to the sensor, which is the force on the support leg 31.

[0044] S04: After the force measurement is completed, put the jack 33 and the extension rod 34 back to the positions on both sides of the support leg 31, and lift the jack 33 at the same time until the load of the support leg 31 is unloaded, turn the bottom of the support leg 31 upward, take out the pressure sensor 4, and turn the bottom of the support leg 31 downward until the support leg 31 contacts the spacer support 32, and the height of the main beam 2 is greater than H; at the same time, lower the height of the jack 33, unload the jack 33, remove the jack 33 and the extension rod 34, and at the same time, the height of the main beam 2 returns to H; tighten the bolts between the support leg 31 and the spacer support 32.

[0045] According to the above steps S01 to S04 , the forces acting on all the supporting legs 31 are measured in sequence.
