浮式防波堤是当前海洋工程装备研发的热点,由于浮式防波堤主尺度大,采用半潜船等工程船运输成本高。文章考虑三种不同类型浮式防波堤采用湿拖方式进行运输,采用AQWA软件,利用数值模拟方法来研究不同海况下浮式防波堤各自由度的运动响应。研究发现,圆筒型和板架型浮式防波堤适用于不同海况下湿拖;网笼型浮式防波堤湿拖过程中运动响应幅值较大,建议使用半潜船运输。通过探究不同浮式防波堤湿拖过程中的运动响应,可为工程实际中浮式防波堤运输提供一定的借鉴和参考。
Floating breakwater is currently the hot spot of marine engineering equipment research and development. Due to the large main scale of floating breakwater, the cost of using semi-submersible ship engineering ships is high. In this paper, three different types of floating breakwaters are considered to be transported by wet-towing method. AQWA software is used to study the motion response of each degree of freedom of the floating breakwaters under different sea conditions by numerical simulation. It is found that the cylindrical and plate-type floating breakwaters are suitable for wet towing under different sea conditions. The amplitude of the motion response during the wet towing of cage floating breakwaters is relatively large, and the use of semi-submersible ships is suggested. By exploring the dynamic response of wet-drag in different floating breakwaters, we can provide some reference and reference for the floating breakwaters in engineering practice.
