为实现深远海石油资源的高效开发，世界首艘深远海原油转驳船（CTV）应运而生，实现了原油从浮式生产储卸油平台（FPSO）到超大型油轮（VLCC）直接转驳。为确保其作业的稳定与安全，有必要对多浮体原油转驳系统的响应特性进行深入研究。基于三维势流理论，结合南海海域的典型海况，采用AQWA水动力软件，建立“FPSO+CTV+VLCC”多浮体有限元模型。通过相关水池试验验证了计算模型的准确性，并分析CTV与VLCC的摇荡运动特性，可知当CTV保持艏向处于迎浪状态时，可实现摇荡运动幅度的最小化，从而有利于保障海上转驳作业的稳定性和安全性。通过时域分析计算CTV在不同海况的运动响应和拖缆张力变化，结果表明在实际作业中，需更加精确调整CTV的动力定位系统来保证与VLCC的安全距离。
To achieve efficient development of deep-sea crude resources, the world's first deep-sea crude transfer vessel (CTV) has emerged, which enables crude transfer from floating production storage and offloading platforms (FPSO) to very large crude carrier (VLCC). To ensure the stability and safety of its operations, it is necessary to conduct in-depth research on the response characteristics of the multi-floating body crude transfer system. Based on the three-dimensional potential flow theory and typical sea conditions in the South China Sea, an "FPSO+CTV+VLCC" multi-floating finite element model is established using AQWA hydrodynamic software. The accuracy of the calculation model was verified through relevant pool experiments, and the oscillation motion characteristics of CTV and VLCC were analyzed. It was found that when the CTV maintains its bow in a wave facing state, the oscillation motion amplitude can be minimized, which is beneficial for ensuring the stability and safety of offshore transfer operations. The motion response and cable tension changes of CTV under different sea conditions were calculated through time-domain analysis. The results showed that in practical operations, it is necessary to adjust the dynamic positioning system of CTV more accurately to ensure a safe distance from VLCC.
