根据烟连线滚装运输的现状、航线自然条件、码头配套设施以及车客流量的预测结果 ,结合滚装船的结构特征 ,确定出船舶的载车载客数 ,估算出长、宽及型深等主尺度技术参数 ,设计了十几种船型方案 ,在经济效益分析的基础上优选出三种合适的船型 ,并最终作出了盈亏平衡分析和敏感性分析 ,结果证明 ,船型方案可行可靠 . According to the status quo of Ro-Ro transport, route natural conditions, wharf facilities and passenger traffic forecast, combined with the structural characteristics of ro-ro ship, the number of passengers carried by the ship is determined and the length, width and depth of the ship are estimated Based on the economic benefit analysis, three suitable ship types are selected, and finally the breakeven analysis and sensitivity analysis are made. The results show that the ship type scheme is feasible and reliable.
