This study presents the experimental analysis of an innovative floatover installation method with the rapid transfer technique, in which the topside loads can be transferred fast and safely. In the rapid transfer process, 30% loads were firstly transferred onto the jackets within only 1 min using the jacking system. Then both the ballast system and the jacking system were employed to gradually transfer the loads onto the jackets. After 70% topside loads were transferred, the jacking system quickly offloads the remaining 30% loads within 1 min. The continuous load transfer operation was simulated in model tests. The complex motions of the barge and the topside as well as the loads on the Deck Support Unite (DSU) and the Leg Mating Unite (LMU) were analyzed. The maximum and minimum motions of the barge and the topside were statistically analyzed as well as DSU and LMU loads. Results indicate the barge pitch motions largely synchronize with the topside pitch before the second jack-down operation. The barge moved forward a little distance after twice jack-down operations. Results indicate DSU loads varied significantly during the jack-down operations and the jacking system should be designed to provide lateral restraints equivalent to 20% of the topside weight.

连续荷载传递过程中采用快速传递技术的浮托装置动力响应试验分析

本研究展示了采用快速转移技术的创新浮托安装方法的实验分析，其中可以快速安全地转移上部负载。在快速转移过程中，使用顶升系统仅在 1 分钟内将 30% 的载荷首先转移到夹套上。然后使用压载系统和顶升系统将载荷逐渐转移到夹套上。在转移了 70% 的上部负载后，顶升系统会在 1 分钟内快速卸载剩余的 30% 负载。在模型试验中模拟了连续负载转移操作。分析了驳船和上部的复杂运动以及甲板支撑装置 (DSU) 和腿配合装置 (LMU) 上的载荷。对驳船和上部的最大和最小运动以及 DSU 和 LMU 负载进行统计分析。结果表明，在第二次升降操作之前，驳船俯仰运动与上层俯仰运动基本同步。两次起重作业后，驳船向前移动了一小段距离。结果表明，DSU 载荷在升降操作过程中变化很大，升降系统的设计应能提供相当于上部重量 20% 的横向约束。
