不同结构形式浮式防波堤湿拖过程中的运动响应研究

Study on Motion Response of Floating Breakwater with Different Structure in Wet Towing Process

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 a hot spot in the current research and development of marine engineering equipment. Due to the large scale of floating breakwater, the high cost of semi-submersible vessels and other engineering vessels are adopted. The paper considers three different types of floating breakwater with wet towing transport way, using AQWA software and the method of numerical simulation study on response of every degree of freedom under different sea conditions. The study finds that cylinder type and plate frame type floating breakwater is suitable for different sea conditions of wet towing; net cage type floating breakwater wet drag during the response amplitude is larger. It is recommended to use the semi-submersible barge. By exploring the motion response of different floating breakwater in the wet towing process, it can provide experience and reference for transportation of floating breakwater in practical engineering works.
