Assessment of Investment Risk in Greek Short Sea Shipping： A Ro-Ro Passenger Ferry Case

The purpose of this paper is to introduce an innovative methodology in shipping investment evaluation based on simulation of a project cash flow. It concerns a complementary approach to current practices and its aim is to provide more information mainly to ship-owners that consider the feasibility of deploying Ro-Ro Passenger ferries. The paper examines a typical semi-conventional RoPax ferry operating in the Aegean Sea. It addresses important economic, operational and procedural issues concerning risk evaluation. The current status is that risk is a notion still strange to main stakeholders. The Greek practice in performing a feasibility study for a project draws on investor＇s experience and feeling aided by a preliminary economic study. The main thesis of this paper is that there are alternative techniques to evaluate investment risk and measure profitability of a project. A Monte Carlo simulation in collaboration with a typical Ro-Ro cash-flow model is implemented to reveal the extent of risk and provide a useful tool for the assessment of future investments in Greek Short Sea Shipping.

城市越江客运轮渡泊位与配船计算方法

国内现行的水运与港口建设规范对客运码头泊位数和航线配船数未给出具体计算方法和公式,通过对客运轮渡运输过程的调查与分析,发现:轮渡发船最小间隔主要受码头停靠时间影响,而渡船停靠时间和航行周期是决定泊位数和配船数的关键.在此基础上,通过简化的数学分析方法,建立了以乘客需求作为主要目标、以建设最少的泊位数和配置最少的渡船数为约束的轮渡泊位和配船数学模型.该模型简单、易理解、效率高,适用于越江客运轮渡的规划和设计.

客滚码头港口作业过程中的危险因素及事故预防措施

针对我国客运滚装码头的港口作业安全现状及发展趋势,就作业过程中可能出现的安全问题,如旅客落水淹溺、车辆碰撞、夹带危险化学品进出港区、船舶靠离泊事故、恐怖分子蓄意破坏等,进行危险因素分析和辨识,提出相应的应对措施,最大限度地保证客滚码头安全运营。

大潮差接船工艺的研究与应用

厦门某泊位改造工程将原有客滚码头改造为专业邮轮码头,并将客滚作业迁移到相邻泊位,故需根据作业条件变化为客滚作业制定新的接船工艺。文中通过对接船高度范围和行车轨迹优化,并对泊位水工结构进行局部改造,构建了新的接船工艺和专用接船升降平台,满足了客滚船舶的大潮差、全天候作业需求。实际运行结果表明,新接船工艺更加合理,并提升了作业效率。
