影响日照附近海域的北上热带气旋特征分析

文中根据对1972年以来北上热带气旋的统计,对北上影响日照附近海域的热带气旋,从北上路径、经过日照时热带气旋的强度、日照本站的风力等方面进行了特征分析。同时,给出了适于日照港港口安全管理部门使用的热带气旋预报信息的来源。论文的结论可供进一步加强日照港防抗北上热带气旋工作,保障日照港防抗台期间船舶和海上作业安全提供重要的参考。     

船舶绕避热带气旋技术方法述评

热带气旋对船舶的威胁极大,如何能做到既保证船舶安全,同时又顾及经济效益是一个重要的课题。此文通过查阅现有航海技术文献和调查航运公司实际绕避热带气旋方法的基础上,对当前应用的几种绕避热带气旋技术方法进行了比较分析和评价,并提出了今后对绕避热带气旋技术方法的研究的建议。     

船舶—热带气旋动态标绘系统

为解决目前航运企业和船舶驾驶人员采用的在“台风位置标示图”上标绘热带气旋和船舶位置的作业方式工作量较大、繁琐、效率低下的问题,提出基于电子海图显示与信息系统(ECDIS)的船舶-热带气旋动态显示标绘系统.该系统应用API、V3和JS等计算机技术,并使用准确率较高的中、日、美三国气象预报机构提供的热带气旋路径预报数据,可将热带气旋的前期移动轨迹、当前位置、未来的移动路径和未来不同时刻的位置自动标绘在航行数据全面的ECDIS平台上;同时,可方便地进行船舶位置的标绘,便于企业船舶管理人员和船舶驾驶人员随时了解船舶与热带气旋在未来不同时刻的相对位置关系及变化.本系统的特点是动态、直观、实时、使用方便,可取代当前使用的传统的“台风位置标示图”,便于企业船舶管理人员和船舶驾驶人员依据本系统提供的信息,迅速、合理地制定绕避热带气旋的新航线,确保船舶绕避热带气旋的成功.

热带气旋生成的预报现状与船舶实用监测信息

介绍了目前对热带气旋发生及发展研究的最新理论及预报业务,指出目前热带气旋发生、发展的预报水平与实际需求仍有很大距离。推荐了美国为弥补热带气旋的发生、发展预报的不足而采取的对热带气旋的胚胎——热带扰动和热带低压进行监测的编号情况和方法。同时,根据几年来对上述情况的跟踪和分析,提供了几个较为实用的,可以及时了解全球热带扰动和热带低压最新发展动态的网站。所提供的理论动态和信息,可使船舶驾驶员和船舶安全管理人员了解目前国内外热带气旋发生、发展的研究和预报现状,在日常工作中及时了解热带气旋初生和发展的动态,最大程度地降低新生热带气旋对在热带气旋活动海区航行船舶的威胁,以达到保障航运企业安全生产的目的。     

大型船舶航行、滞航及锚泊中的防抗台操作

热带气旋(Tropical Cyclone)是发生在热带或副热带洋面上的低压涡旋,是一种强大而深厚的热带天气系统,热带气旋发展到极端就成为台风。台风具有突发性强、破坏力大的特点,是世界上最严重的自然灾害之一。在海上,船舶一旦坠入台风大风圈内,会产生剧烈摇摆和颠簸,船上的设备和物品会发生危及安全的位移,货物会发生损坏和灭失,更进一步,船舶在大风浪中稳性失却导致船舶倾覆。所以,海船防抗台操作成为船舶驾驶人员必须掌握的操纵技术。

船舶避让热带气旋等天气系统的数学模型研究

热带气旋等重大天气系统对海上航行船舶的危害很大,传统的避让方法无法定量的给出热带气旋等天气系统的遭遇相关参数,通过相对运动法的的研究,计算出遭遇热带气旋等天气系统的数学模型表达式,让驾驶员在接受了气象报告后直接将热带气旋相关的参数与本船运动参数输入表达式,直观的得到与热带气旋等遭遇的最近距离、遭遇所剩的时间、是否需要避让、避让的幅度是多少等数值,对船舶避台等问题安全进行量化。

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.
