Precision management is an important subject of modern shipbuilding.The precision of steel structure manufacturing reflects the level of ship construction.Taking the 20000-TEU-class container ships equipped with LNG fuel tanks as the example,the problems and difficult points of accuracy control of new type container ships are briefly analyzed and the targeted corresponding solutions are proposed.A solution based control standard is established to standardize the subsequent production.In the process of research and analysis,finite element calculation,three-dimensional physical measurement,precision analysis software and other means and tools are applied,following the idea of combining theory with practice,step by step,continuously promoting the organic unity of physical size,calculation results and control standards.Finally,the control standard is guaranteed to be feasible and the expected purpose of good physical size accuracy is achieved.The proposed research,analysis and management experience of large-size container ships provide reference to related practitioners in the field.
