Embodiment 1
[0041] figure 1 It is a schematic flowchart of a method for controlling the hot work of an FPSO cargo oil silo provided in Embodiment 1 of the present invention, see figure 1 , the FPSO cargo oil silo hot work control method, including:
[0042] S110: Obtain the maximum acceptable temperature of the storage medium in the adjacent compartment.
[0043] Since adjacent compartments may store different storage media, and different storage media have different physicochemical properties, their corresponding ignition packet points are also different. Under a certain temperature, it is relatively stable, and beyond this temperature, it may cause combustion or explosion. Therefore, the maximum acceptable temperature of the storage medium in the adjacent compartment needs to be predetermined. The maximum acceptable temperature may be the maximum temperature acceptable for the medium or a specific temperature value below the maximum temperature.
[0044] Optionally, the obtaining th...
Embodiment 2
[0058] figure 2 This is a schematic flowchart of a method for controlling the hot work of an FPSO cargo oil tank provided in Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. Specifically, the method may further add the following steps: The same material is actually welded, and the distribution of the molten pool and temperature field is measured, and the simulated molten pool and temperature field distribution are corrected according to the measured molten pool and temperature field distribution to obtain the molten pool and temperature field distribution.
[0059] see figure 2 , the FPSO cargo oil silo hot work control method, including:
[0060] S210: Obtain the maximum acceptable temperature of the storage medium in the adjacent compartment.
[0061] S220, obtain the maximum temperature requirement of the material of the cabin.
[0062] S230: Determine a corresponding hot work mode according to the hot ...
