确保小型船舶在长江下游水域安全停泊的思考和对策

为规范小型船舶停泊秩序,确保船舶停泊安全,稳定港口生产作业形势,本文就小型船舶在长江下游水域停泊行为进行探讨,提出一些确保船舶停泊安全的思路和具体对策。     

船舶在港停泊时间的因素分析

分析船舶在港停泊时间的长短，对船舶运营和码头经营的效益，具有十分重要的意义。从船舶在港停泊时间的基本含义入手，通过对船舶在港停泊时间的构成分析，提出了明确的缩短船舶在港停泊时间的具体办法。     

关于长江航运安全方面几个问题的便民解答

一、三峡库区蓄米156米后,库区船舶停泊时应注意哪些事项?答:随着三峡水库156米运行及三峡船闸完建工程实施单线运行,三峡库区航路和锚泊区发生了很大变化,长江海事局结合船舶流量和水情变化实际,在三峡库区调整和增设了150个船舶临时停泊区,其中普通船舶停泊区145个,危险品船舶停泊区5个,对每个停泊区的地点位置、范围及停泊的数量和船舶种类都有具体规定     

基于实船试验的三峡船闸船舶过闸系缆力影响因素

三峡大坝船闸建成之后,库区船舶通航条件得到明显改善,船舶大型化发展迅速。船闸内系缆设施的承载能力有限,而船舶大型化发展应满足闸室安全停泊的要求。通过实船试验方法,选取典型大尺度过闸货运船舶,实测闸室停泊过程中系缆状态和相应数值,分析影响船舶过闸系缆力的主要因素并提出改善船舶过闸过程中停泊安全的有效措施。     

船舶在高寒水域航行、停泊注意事项

船舶在高寒水域航行与停泊安全隐患极大,水域中的海冰会对船舶产生不同程度的影响。文章对船舶在高寒水域中航行与停泊的注意事项进行研究,以期向人员、船舶与海洋环境的安全提供保证。     

洪泽湖船舶安全停泊区开建

洪泽湖湖区的又一项“救命工程”——洪泽湖船舶安全停泊区新近开工建设，建成后可为400多艘200吨位的船舶在恶劣气候下避风躲险。洪泽湖航道每年有10多万艘运输船舶沿淮河入湖进入京杭大运河。由于洪泽湖气候多变，给航行船舶带来较大威胁.该安全停泊区约16万m^2，防坡堤采用实体斜坡堤，建成后可停泊200吨位船舶400多艘，不仅可以为船舶提供安全待闸的场所，还可在恶劣天气下发挥避风港的作用，有效保护船民航行安全。     

福姜沙水道整治建筑物警示保护研究

长江福姜沙水道通航船舶密度大、大小型船舶夹杂且小型船舶习惯航路复杂,船舶临时停泊水域及锚地长期紧张。长江南京以下12.5 m深水航道二期工程福姜沙水道整治建筑物工程完工后,小型船舶可能误入、闯入整治建筑物水域,对整治建筑物安全稳定及通航船舶的自身安全造成严峻挑战。通过整治建筑物警示保护方案研究,对福姜沙水道整治建筑物保护和船舶通航安全提供了有力的保障,为航道整治建筑物的保护提供了借鉴意义。     

中国港口协会 关于警惕发生集装箱空箱压港堵港现象的紧急通知

各有关单位： 当前，国际金融危机席卷全球并已波及经济实体，部分船公司采取了取消航线和封存船舶等举措来规避经营风险和降低营运成本。一些国外船公司也纷纷到我国沿海和长江港口寻找停泊闲置船舶的锚地和计划长期堆置集装箱空箱的场地。有些港口企业为突击完成年度集装箱吞吐量指标，     

智能船舶电子签证系统的物联网架构研究

随着航运业的发展,传统的船舶签证系统已经越来越不能满足现在航运业的发展。传统电子签证系统在船舶到达港口时需要停泊,影响船舶航行效率,而基于物联网结构的智能电子签证系统利用RFID射频﹑AIS自动识别系统及电子签证平台实现了船舶电子签证的自动化及远程化,使船舶到达港口不再需要停泊。本文研究现有物联网结构及船舶电子签证系统架构,在此基础上研究一套高效智能船舶电子签证平台,最后验证系统的有效性。

Maritime security guidelines: a study of Swedish ports’ perceived barriers to compliance

ABSTRACT

Due to the constant risk of piracy and terrorist attacks which cause disturbances within international shipping of goods, barriers to the adoption of maritime security guidelines (MSGs) at European ports have become prevalent. In this paper, a conceptual framework was created to explore the perceived barriers that prevent compliance with MSGs. To verify the conceptual framework, empirical data were collected using a mixed-methods approach, which was comprised of interviews with national experts and a survey of 47% of Swedish ports involved in the shipping of goods. According to the presented framework, the perceived barriers of Swedish ports to compliance with MSGs were linked to collaborations within the Swedish Maritime Security stakeholder network, available resources and educational knowledge about security culture. In addition, the perceived barriers of smaller ports were linked to the adaptation to MSGs at different levels and the absence of specific tools of maritime security management. Due to an increased interest in international shipping of goods, this paper is currently one of few that addresses the barriers to compliance with MSGs. Moreover, the paper presents a general conceptual framework, novel managerial implications and recommendations for future research.

Ship, port and supply chain security concepts interlinking maritime with hinterland transport chains

As maritime processes do no stop at sea ports, hinterland operations have to be considered and addressed as well. This becomes obviously on designing and managing seamless cargo and information flows from/to hinterland regions via sea ports from/to transcontinental markets. Nowadays, also security-related aspects need to be tackled in order to enable continuous flows corresponding to security legislations and technical requirements set up in the field of maritime and intermodal hinterland transport. Ensuring transport security within the European transport market requires both adequate security legislations and innovative concepts. While for the maritime sector, including sea ports, security regulations are already in force, hinterland operations (road, rail and Inland Waterway Transport) are only indirectly affected today, either on carrying out transports from/to sea ports or exporting commodities to overseas territories. This results in the need for innovative security strategies and concepts combining maritime with hinterland transport enabling seamless security processes.     

Private sector responses to port privatization in India

Indian ports offer good opportunities for investors prepared to take a long-term view, and some successful small-scale private contracts are already in place. But strategic direction from the centre is required to accelerate and broaden the privatization process, and ensure that private interest in the ports sector is maintained.

Will a national port regulator solve congestion problems in Australian ports?

Australia's ports are an integral part of the nation's economy, which relies heavily on trade. In Australia, the governance of ports is the responsibility of the governments of Australia's six states and the Northern Territory, all of which have their own legislation covering the running of the ports and the establishment of port corporations. The respective legislation governing the running of Australia's ports is not uniform, and neither are the models for port management that they create. In May 2005, the then Deputy Prime Minister and Federal Transport Minister announced that the Commonwealth planned to take control of the planning and investment decision making of Australia's ports. The reasoning behind this is said to be Australia's poor trade performance and bottlenecks in ports which hold up trade and ultimately cost money. The Federal government has sought to do this under Section 51(i) of the Australian Constitution in order to update and integrate Australia's transport system. This announcement has caused disquiet among the states that had no previous notice of the announcement and for which ports are a major source of revenue. The transfer of power to the Commonwealth may lead to the Commonwealth being able to take further powers from the states, not only in relation to the ports but in relation to other areas such as industrial relations. Industry groups claim they have been pushing for a larger role for the Commonwealth in the running of the nation's ports, but question as to what extent the Commonwealth should be involved.

Specialization and economic impact of the ports of Montreal,Quebec, Saint John,and Halifax

Specialization in cargoes and forelands is defined for the ports of Montreal, Quebec, Saint John, and Halifax using a variation of the location quotient. Economic impact is also defined using the location quotient. All ports are shown to have some degree of specialization; whereas, Saint John and Halifax have relatively greater economic impact. It is suggested that the four ports should be encouraged to develop their specializations. However, are the benefits to the shipping industry in following such a policy outweighed by the losses to the local economies because investment in certain ports does not take place?

空间有限元理论在码头重型铺面结构设计中的应用

对于承受特重车辆荷载的港口铺面工程,其设计已不能按适用于普通车辆荷载作用的铺面设计规范进行控制设计。文中以国外某港口中承受特重车辆荷载的铺面工程实践为例,对此类铺面板采用有限元方法进行了空间弹性地基板受力分析,根据分析结果,对铺面板按钢筋混凝土构件进行抗弯强度、抗剪强度计算及限裂性验算,能够较直观地得出各种荷载情况下,铺面最不利位置及内力大小。
