| 摘 要： | 浮托安装法,是相对于传统吊装法的一种新型海洋平台安装方法,具有起重能力大、作业周期短、安装费用低、适用范围广、操作安全方便等优点,解决了海上大型平台组块的安装问题。为了研究横荡护舷对浮托安装的影响,首先对海洋平台浮托安装中的护舷装置进行了介绍,然后针对某工程实例应用AQWA软件进行了数值模拟,并进行了模型验证。从时域方面对就位状态下的浮托模型进行了耦合动力分析,研究了横荡护舷参数对驳船运动和撞击力的影响规律。研究表明,横荡护舷可以有效地减小驳船运动和撞击力,其限位和缓冲作用与护舷尺寸及护舷刚度均有关。研究结果可为实际浮托安装工程提供重要的参考。

| Abstract: | Float-over is a new offshore installation method compared with traditional lifting methods, with the advantages of large lifting capacity, short operation time, low installation cost, wide application, safe and convenient operation, etc. It solves the problem of installation of large offshore platform. In order to study the influence of the swaying fender on the float-over, the fender devices of float-over installation for offshore platform are first introduced. Then, a float-over installation numerical simulation is demonstrated using AQWA based on a practical engineering installation, and the model test results are used to verify the numerical results. The coupled dynamic analysis of float-over model is performed in the time domain under docking situation. Particular attention is paid to the impact of different swaying fenders parameters on the motion and impact force of barge. The results show that the swaying fender can reduce the motion and impact force of barge effectively, and its limitation and buffering performance are related to its size and stiffness. The research results can provide an important reference value for practical float-over projects. |
