摘　　要：系泊定位技术是影响建设平台安全性的关键技术之一,特别是在岛礁附近极浅水变水深的地形环境条件下,水深、非对称地形对系泊系统的定位性能有很大的影响。通过对平台及其系泊系统、地形条件、风浪环境条件的模拟,针对岛礁建设平台系泊系统开展水池模型试验研究,得到了平台在不同海况下的六自由度运动、系泊受力等数据。通过对试验数据的分析处理,验证了平台系泊系统满足安全规范要求,同时还总结出预张力、波浪周期对系泊性能的影响。Mooring positioning is one of the key technologies affecting the safety of construction platforms,especially in shallow water and variable-depth seabed.Depth of the water and dissymmetric topography has a great influence on the positioning performance of mooring system.By the simulation of the construction platform and its mooring system,terrain conditions,environment conditions including the wind and wave,the research on model test of the mooring system for construction platform is carried out.According to the comparison and analysis of 6-DOF motion and mooring forces,it is verified that the platform mooring system meets the safety requirements.And the influence of pre-tension and wave period on mooring performance are also summarized.
