叠船运输方式下的半潜船耐波性分析

以叠船运输方式下的半潜船为研究对象，采用CATIA软件进行三维建模。基于AQWA软件计算在规则波中不同浪向、不同航速和不同吃水下的响应幅值算子(Response Amplitude Operator, RAO),分析在不规则波中不同海况条件下货物绑扎设计关键点的加速度变化，发现浪向、航速和吃水等因素对RAO的影响规律。研究结果可为叠船运输方式下的半潜船安全运输提供运动预报，为货物绑扎设计提供依据。

Seakeeping Analysis of Semi-Submerged Ship under Ship-Stacked Transport Mode

Taken the semi-submerged ship under ship-stacked transport mode as the research object, a three-dimensional model is built with CATIA software. Based on AQWA software, the Response Amplitude Operator (RAO) under different sea directions, speeds, and drafts in regular waves is calculated, the acceleration changes of key points of cargo lashing design under different sea conditions in irregular waves are analyzed, and the law of the influence of wave direction, speed, and draft on RAO is found. The research results can provide the motion prediction for the safe transport of semi-submerged ship under ship-stacked transport mode, and provide the basis for cargo lashing design.
