摘　　要：以重约15463 t的平台上部组块为例,对在中国南海海域采用动力定位技术进行大型组块海上浮托安装的方案设计、数值分析以及现场施工过程中需要关注的细节进行较详尽的介绍。结果表明:动力定位浮托设计方案可行,桩腿对接耦合缓冲装置运动、横荡护舷受力等均接近设计能力限值,在现场作业过程中应格外关注;动力定位浮托技术适用于南海等海况条件较恶劣的海域。研究结果对今后其他同类型工程项目的设计和施工有较大的参考借鉴意义。Taken the topside weighing about 15463 t as an example,the scheme design and numerical analysis of large-scale topside which is installed by dynamic positioning floatover method in the South China Sea and the details that need to be paid attention to in the construction process are introduced in detail.The results show that:the dynamic positioning floatover design scheme is feasible,the motion of the pile leg coupling buffer device and the force on the lateral fender are close to the design capacity limit,and special attention should be paid to in the on-site operation process;the dynamic positioning floatover technology is suitable for harsh sea conditions in the South China Sea.The results can provide reference for the design and implementation of other similar projects in the future.
