In order to improve the efficiency and safety of the low-temperature piping unit hoisting in the cargo machinery room,finite element analysis of the hoisting scheme is conducted,and relevant processes are designed and optimized.Taking the low-temperature piping unit of the cargo machinery room of a 14 000 m3 refueling ship as an example,finite element simulation is conducted using software such as HYPERMESH,MSC.Patran.Preliminary model reconstruction and mesh division are carried out for the low-temperature piping system unit,and the lifting scheme is determined and calculated and analyzed.Based on this,the reconstructed model,mesh,and lifting scheme are iteratively optimized to obtain finite element calculation results that meet production requirements.
