影响内河船舶大型化发展达到最佳状态的要素

为使船舶大型化发展符合水路运输实际需要,介绍欧洲内河船舶运输发展经验,结合我国内河船舶大型化发展现状,探讨影响船舶大型化发展达到最佳状态的重要因素,包括船舶最佳经济运营吨位、船舶吨位大小与港口作业效率的匹配关系、船舶吨位与航道规划的关系、船舶大型化与企业联盟的协同发展关系。船舶大型化是充分发挥水运比较优势的必由之路,合理权衡大吨位船舶发展及其对业态的影响,方能彰显出内河高质量发展的内涵。     

浅谈辛氏第一法则在内河船舶吨位核算中的应用

船舶吨位是衡量船舶容积大小和装载能力的重要参数。船舶吨位丈量和计算是船舶检验中的重要而基础的检验项目。本文旨在探讨通过辛氏第一法则在内河船舶吨位核算中丈量和计算不规则型容积时的应用。     

河船净吨位计算探讨

从总吨位与净吨位的定义出发，通过对典型船舶的计算进行分析比较，确定了内河甲板货驳的净吨位系数；并区分不同功能与用途，提出了内河趸船的净吨位系数，为修订完善吨位丈量规范提供参考。     

内河大吨位船舶安全监管不容忽视

近年来,内河运输船舶呈现向大吨位方向发展趋势,令人欣喜.但由于大吨位船舶的大量涌入,导致内河航道不堪重负,航道堵塞和水上交通事故频频发生,给国家经济和人民的生命财产带来一定的危害.     

我国内河航道发展规划技术等级评定方法

为重新评定我国内河航道等级以适应发展需要,确定内河航道发展规划技术等级评定方法的步骤包括航道现状评定、航道发展评定和航道发展技术等级评定,并以交通流理论为基础结合航道运量预测、航道服务水平、设计小时系数、加权平均船舶吨位、航道设计通过能力计算方法等理论,以及内河航道标准船型船舶吨位与船长的关系对内河航道等级评定方法进行研究。以东江航道为实例进行应用,验证该方法的可行性,结果表明东江航道等级应重新定级为Ⅲ级。     

修改内河船员实操考试办法的探讨

1内河船员实操考试办法修改的必要性和可行性1.1必要性①为适应《10规则》的需要。随着近年来内河航道条件的大幅改善,内河船舶的吨位普遍提高,高等级船舶增多,内河各等级船舶的分布情况发生了较大变化,且现代化航行设施逐渐普及,鉴于此,《2010年内河船舶船员适任考试和发证规则》(简称《10规则》)将原来的5个等级调整为三类船舶,且每个等级所适用的范围都有了较大的提高。这种变化使2007年《内河船舶船员实际操作考试办法》(07实操考试办法)第五、六条有关主考官和评估员应持有

修改国内船舶吨位丈量方法的建议

近年来,随着我国商品经济形势的发展,船东对船舶吨位数值日益重视,使现行国内海船和内河船的吨位丈量方法中存在的不合理之处日渐突出,到了必须解决的地步.     

交通部发布《全国内河船型标准化发展纲要》

交通部日前发布《全国内河．船型标准化发展纲要》，确定到2010年，川江及三峡库区、京杭运河、长江、珠江三角洲及其千流基本上实现船型标准化、系列化，平均吨位较2004年增加一倍，通航设施利用率较2004年提高15％，船舶安全技术性能进一步提高；到2020年，内河船舶实现标准化和系列化，平均吨位较2004年增加两倍，通航设施利用率较2004年提高30％，船舶安全技术性能接近或达到国际先进水平。     

内河船舶吨位的现场丈量复核

船舶吨位的确定通常是由船舶检验部门依据有关公约或规范，通过对船舶的图纸和资料进行丈量计算后核发吨位证书。但是由于种种原因，目前内河航行的部分船舶存在严重”大船小证”或”船证不符”的情况，这就需要海事部门加大现场检查力度，提高执法人员专业技术水平，有效甄别和杜绝此类违法现象。作者总结多年船舶检验和海事监管经验，提出一些船舶吨位现场丈量和复核计算的方法和建议，以供参考。

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.
