摘要
受线型收缩的影响,集装箱船尾部区域在搭载过程中底部坞墩及支撑工装布置较为困难,船坞内搭载精度控制、坞墩布置优化及采用合理的工装拆卸工艺至关重要。以23 000 TEU超大型集装箱船首制船为研究对象,结合现场实船搭载流程,针对该船尾部船体下沉变形、底部坞墩及支撑工装承力开展有限元分析。通过与现场实测数据比较可知,其预报结果与实船搭载监测情况比较接近,验证了理论分析预报方法基本可以准确模拟搭载过程中的船体尾部下沉趋势及坞墩受力情况。基于预报结果,提出该船型尾部搭载的反变形量设置、坞墩布置以及支撑工装拆卸建议,为船厂优化搭载工艺及保证搭载作业安全提供理论支撑。
Affected by shrinkage of ship’s line,the arrangement of docking block and pillar supports for container ship stern and engine room area in the carrying process is relatively difficult.The precision control of the loading in the dock,the optimization of the dock pier layout and the adoption of a reasonable tooling and disassembly process are very important.Taking a 23 000 TEU ultra-large container ship as the research object,combined the actual ship carrying process,the finite element analysis for the sinking of the ship stern docking block,applied loads to dock and pillar supports are carried out.The results show that the predicted results are close to the monitoring condition of the ship by the comparison with the actual measured data,and it verifies that the theoretical analysis and prediction method can basically simulate the sinking trend of ship stern and the applied loads of dock block in the process of ship docking.Furthermore,the suggestions of the reverse deformation setting,dock block layout and the disassembly of the supporting tools for the ship’s stern are proposed based on the forecast results,which provide theoretical support for the shipyard to optimize based on the forecast results,and ensure the safety of the building operation.
