【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]:Floatation mounting method is a new type of offshore platform installation method compared with traditional hoisting method. It has the advantages of large lifting capacity, short operation period, low installation cost, wide application range, safe and convenient operation, etc. The installation problem of large offshore platform block is solved. In order to study the influence of swinging fender on the installation of floating bracket, the fender installation of offshore platform is introduced firstly, and then the numerical simulation is carried out with AQWA software for an engineering example, and the model is verified. In this paper, the coupling dynamic analysis of floating support model in position is carried out in time domain, and the influence of swinging fender parameters on barge motion and impact force is studied. The results show that the swinging fender can effectively reduce the motion and impact force of the barge and its limit and buffer action are related to the size of the fender and the stiffness of the fender. The results can provide an important reference for the actual floating bracket installation project.
