取消船舶签证条件下的内河海事安全监管探析

船舶签证作为海事机构管理船舶的有效抓手,承担着船舶适航性和船舶动态信息获取两大核心职能,一旦取消船舶签证的配套措施跟不上,将会对长江水上安全造成重大影响。为了提高船舶签证取消后海事安全管理水平,促进海事安全监管模式的转变,在对船舶签证取消前后利弊分析、船舶签证取消后对海事安全监管所产生的影响的基础上,提出取消船舶签证后的内河海事安全监管相关对策,为船舶签证取消后的内河海事安全监管思路提供参考。     

基于物联网的船舶电子签证系统

现有的船舶电子签证系统依然存在着并发性能差的问题,为此提出物联网的船舶电子签证系统设计。为了提升船舶电子签证系统的并发性能,基于物联网搭建船舶电子签证系统架构,以此为基础,设计船舶电子签证系统功能模块,主要包括基本信息管理模块、签证管理模块、数据库设计模块以及界面设计模块,通过功能模块的设计实现了船舶电子签证系统的运行。通过测试结果可知,与现有船舶电子签证系统比较,设计的船舶电子签证系统极大地提升了并发性能,充分显示出设计的船舶电子签证系统具备更佳的使用性能。     

关于湖州市本级辖区船舶签证的初步调研及思考

文中基于笔者对湖州市本级辖区船舶签证状况的初步调研和自身工作实际,提出了当前辖区船舶签证的突出问题,并结合新船舶签证规则的实施,探讨如何更好地改进现有船舶签证模式。最终阐述个人观点,即船舶短期定期签证最符合当前辖区的海事监管要求和广大船舶的根本利益。     

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。     

由行政许可的规定谈船舶签证管理方式的改进

文中在介绍船舶签证行政许可性质来源的基础上,根据我国《行政许可法》对行政许可的有关规定,以及其他有关的法律文件,结合船舶签证管理现状,分析了船舶签证设定为行政许可事项存在的若干问题,提出了改进船舶签证管理方式的建议,并阐述了船舶签证由行政许可审批改为行政报备管理方式的必要性和可行性。     

浅析船舶签证

完善船舶签证管理

船舶出口签证管理是保障船舶安全重要的一环。长期以来，各级海事机构都能够依照《中华人民共和国船舶签证管理规则》严格做好船舶签证工作，对“四客一危”等重点船舶有针对性地扩大了登轮签证的范围，从而堵塞了传统签证工作中审批与实际监管相脱离的漏洞。尽管如此，由于部分管理相对人受经济利益驱使及其它客观

对沿海船舶逃逸签证的思考

随着海运业的开放和航运业的蓬勃发展，越来越多的私营船舶参与到沿海航运中来。目前，在沿海港口存在部分私营船舶违反《中华人民共和国船舶签证管理规则》(下称《船舶签证规则》)的规定，逃逸船舶进出港签证的现象，并且逃逸签证的船     

船舶签证管理亟待加强

船舶进、出港或在港内航行、作业实行签证制度,是维护水上交通秩序的重要手段之一。1993年4月5日,交通部颁布的《中华人民共和国船舶签证管理规则》(以下简称《签证规则》),目前在执行中问题不少。 1.《船舶签证簿》填写不规范。签证员不留名、不填写日期是常有的事,有的甚至就在《船舶签证簿》上盖个章了事。对进港签证栏的始发港、靠泊地点和出港签证栏的驶往港、开航地点瞎填一气。 2.船舶逃签、漏签现象严重。《签证规则》及《江苏省渡口管理办法实施细则》规定:渡船和从事定线短途运输及作业的船舶,可以办理定期签证,但是执行的结果却不能令人满意。我县132处渡口中,只有几处能坚持定期签证,在县内从事短途运输的船舶办理签证的也是少数。一些吨位较大的跑长途的船舶为了少缴港务费,有意识地逃避签证。近年来一些新的港口和货物集散地出现,签证站点远离装、卸货地点,使逃避签证现象更多。

Recent progress on wave induced loading measurements in warships

Recent measurements of wave induced hull strain and flexure in RN warships are presented together with the derivation of the current design criteria for extreme hull girder bending loads. The history of the development of the shipboard instrumentation used is given and recent developments to improve the quality and ease of analysis of the data are described. An unexpectedly high transverse asymmetry in the longitudinal strains measured in destroyers is shown to be the result of a combination of vertical and lateral bending in oblique seas. Finally recent theoretical comparisons between the loading of Deep-Vee hulls and conventional UK rounded bilge hulls are presented which demonstrate the higher loading experienced by this type of hull form.

Impact of regulation on the performances of long-distance transport services: A comparison of the different approaches in Sweden and Norway

Despite the many socio-economic similarities between Sweden and Norway, differences in jurisdiction, organisation, cooperation, and financing of long-distance passenger train and coach services have led to the development of four distinctively different ways of serving the markets. This paper describes how the train and coach markets have developed in the two countries, with emphasis on regulatory and industrial structure and a couple of performance variables.Looking at passenger rail, both countries separated infrastructure from operation over a decade ago. However, while Norwegian rail is characterised by an almost monopoly supplier, rail services in Sweden are partly decentralised to the responsibility of county authorities and are widely subjected to competitive tendering. The rest of the network is about to be opened up for on-the-track competition. Swedish Rail (SJ) has spent the last decades consolidating its core business (passenger rail) and sold out its other businesses. In contrast, the Norwegian state rail (NSB) has expanded its business to become a major bus operator and property owner, with extensions also into the Swedish market.The coach industry was more recently deregulated in both countries. The Swedish coach market is dominated by privately owned companies operating services to and from Stockholm. In Norway, state-owned NSB is a major coach operator on medium distance routes, and is also the largest partner of Nor-Way Bussekspress which totally dominates long-distance coach services. Further, the Norwegian coach market is characterised by cross-ownership and cooperation which has enabled an extensive route network which covers most of Norway.We find distinct differences in achievements in the two modes and in the two countries. Swedish rail services have succeeded in winning market shares and in renewing and developing both infrastructure and service levels to a greater extent than the Norwegian model. On the other hand, the Norwegian coach market seems to be more developed and efficient compared to its Swedish counterpart.The paper concludes with a discussion on the possible links between the different approaches and the performance observed, with the aim to stimulate further and more detailed research on some important issues.
