我国自船自代型船舶代理公司转型研究

自船自代型船舶代理公司一直都被定义为其母公司的保障部门,在经历了金融危机后,高额的经营成本以及原有业务量的剧减促使自船自代型船舶代理公司转型,开展公共代理业务便成了该类企业的新利润源.文章从自船自代型船舶代理公司自身特点出发通过分析其开展新业务可能遇到的问题,并提出相应的建议     

Routing and fleet deployment in liner shipping with spot voyages

The routing, scheduling and fleet deployment is an important integrated planning problem faced by liner shipping companies which also lift load from the spot market. This paper is concerned with coordinating the decisions of the assignment of ships to contractual and spot voyages, and the determination of ship routes and schedules in order to maximize profit. We propose a new model for representing voyages as nodes of a directed graph which is used to build a mixed integer programming formulation. Besides contractual and spot nodes, another type of node is put forward to represent a combination of a contractual voyage with one or more spot voyages. In addition, the concept of dominated nodes is introduced in order to discard them and reduce the effort of the search for an optimal solution. A set of test problems has been generated taking into account real world assumptions. The test problems are solved by an optimization software and computational results are reported. The results show the potential of the approach to solve test problems of moderate size.     

航运纠纷中诉讼程序当事人不到庭的处理规则

随着我国海洋运输业和航运服务业的迅速发展,航海运输中的各种纠纷正呈逐年上升趋势,其中不乏海事行政诉讼案件.在海事行政诉讼案件中,当事人因为各种原因,有时会拒绝参与诉讼程序,特别是不到庭参加诉讼,这会对海事行政诉讼案件的恰当处理带来不利影响.此种情形下,海事法院应当从合法性和合理性两方面出发,结合法律规定及具体情形,对航运纠纷中海事行政诉讼当事人不到庭的理由作出正当性判断,并据此适用不同的处理规则,以确保海事行政纠纷得到妥善解决.     

预防和降低船上疲劳的“STEP”机制

该文通过综合分析业界有关研究成果和国际海事组织关于船上疲劳的有关导则手册,梳理当前普遍认同的导致船上疲劳的因素并结合实际分析在预防和降低船上疲劳的过程中所面临的障碍,有针对性地提出从社会(Society)、技术(Technology)、经济(Economy)和政策(Policy)层面共同着手建立关于预防和降低船上疲劳的“STEP”机制。     

从《内河通航标准》看某些特殊限制性航道水深的确定

通过对国家标准《内河通航标准》(GB50139-2004)[3]的分析和计算,找出了影响航道水深的主要因素,根据特殊限制性航道———中间渠道和渡槽的运行特点,推求出它们水深的计算方法和结果。航道水深由船舶吃水和富裕水深组成,富裕水深中考虑了船体下沉量、通航建筑物运行引起的水位变幅、船行波以及触底安全富裕量。并参照《内河通航标准》给出了航道的弯曲半径,形成了完整的特殊限制性航道尺度系列。     

Sailing into a dilemma: An economic and legal analysis of an EU trading scheme for maritime emissions

On the basis of a joint economic and legal analysis, we evaluate the effects of a “regional” (European) emission trading scheme aiming at reducing emissions of international shipping. The focus lies on the question which share of emissions from maritime transport activities to and from the EU can and should be included in such a system. Our findings suggest that the attempt to implement an EU maritime ETS runs into a dilemma. It is not possible to design a system that achieves emission reductions in a cost efficient manner and is compatible with international law.     

不稳定散件货物的系固研究

在船舶运输中，解决不稳定散件货物系固的计算验证问题，对于船舶、人员、货物及环境的安全具有重要的现实意义．通过分析散件货物对支撑构件的作用情况，获得散件对支撑构件的作用力和弯矩，比较支撑构件受到的最大弯矩和许用弯矩，运用计算方法和面向对象的C#语言编程验证不稳定散件货物系固方案的合理性和安全性．     

欧洲港口海运产业集群发展模式

欧洲有着众多的港口海运业集群,典型的有以伦敦为核心的英国海运服务业集群、以鹿特丹和阿姆斯特丹为中心的荷兰港口与港口服务业集群和以奥斯陆为中心的挪威航运与航运技术集群.梳理发现,港口海运业集群发展的基本模式为:航运和港口资源的历史累积体现了路径依赖,国家政策革新和企业创新是外部动力,解除路径锁定及生产服务于全球航运市场的垄断性产品或规则是核心动力.港航企业集群发展的关键路径是营造发展环境和蓄积专业性知识,完善专项资源配置能力和功能,通过企业成群、产业成链、市场创新,形成多部门、多层次、协调合作、共同提升的国际港口和航运服务体系,提供迅捷而专业的解决方案,引领国际港航服务发展.中国沿海港口产业和港口城市迅猛发展,应科学认识港航集群,多方联动研发创新,促进中国港口海运集群发展.
