液体化工品运输码头职业病危害调查分析

液体化工品运输码头职业健康管理尚处于起步阶段,为掌握行业从业人员的职业健康现状,提升从业人员职业健康管理水平,以某企业配套液体化工品运输码头为调查对象,根据国家有关职业卫生标准,采用现场职业卫生学调查与工作场所职业病危害因素检测相结合的方法,识别该码头职业病危害因素,检测危害程度,分析职业病致病因素。调查结果表明,该码头职业健康总体情况基本良好,但噪声指标轻微超标,有个别从业人员耳塞佩戴不正确,建议通过改进防护技术、加强行政管理等手段进一步提升码头职业健康管理水平。     

Maritime logistics as an emerging discipline

The evolution of maritime logistics as an emerging discipline has resulted, to a large extent, from the increasing and varied demands of shippers and customers and the rapidly changing role of ports in the context of supply and logistics chains. Scholars are becoming increasingly aware of the need to integrate logistics and supply chain management concepts in the maritime transportation chain and operations. This article aims to provide a review and foundation for understanding the domain of maritime logistics and to assess its potential as an emerging discipline. To do so, a framework for understanding the various aspects of maritime logistics strategy and implementation is developed. A synthesis of the existing knowledge on maritime logistics is done by integrating diverse explorations forming the basis of this framework. We draw upon the literature on maritime transport and ports and primarily theliterature that analyses concepts by adopting an economic or management perspective.     

Advances in port studies: the contribution of 40 years Maritime Policy & Management

Port economics, management and policy have progressively emerged as a distinctive research field, and a core part of maritime economics. This paper provides an analysis of all the 267 port studies published in Maritime Policy & Management (MPM) since its inception in 1973. This paper provides a content analysis for seven interrelated research theme categories including main research topics and methods, authorship distribution and citation counts. It is demonstrated that MPM played, and continues to play, a key role in publishing research on seaports. The published research increasingly applies established analytical frameworks to ports. The paper concludes with a discussion on current challenges for port-related research.     

Overseas trade vis-a-vis overseas shipping: Growth and performance in India (1999–2009)

Maritime trade has been and even continues to account for about a lion's share of India's total cargo volumes. Despite the growth of multimodal transport (by land, water and air), shipping still continues to be the major mode of transport in the bulk carriage of country's overseas trade. In view of this vital role of shipping, in the first four decades of independence, under the initiative of planned development and active government support, India's shipping and port sector saw dramatic growth in their performance to build adequate national fleet, in keeping up with the transport of overseas cargo. However, the onset of economic liberalization in 1991 has given rise to many new dimensions in the development of the shipping and port sector of the country with a significant redefinition of shipping and port services, in response to the new global trend patterns. For instance, it has also established the new era of containerization in the mode of cargo delivery from the dominance of the era of bulk and break-bulk trade during the decade of sixties and seventies. Moreover, as global competition increases, in response to this emerging trade patterns within this country, India's volume of traffic growth also increases manifold. So, India's shipping and port sectors need, significantly, to build up and furnish their capacity by increasing the frequency of this mode of transport i.e. the growth of the national overseas fleet to meet this surging demand. This paper, therefore, have focused on this role of shipping in such rising overseas trade, with a view to examine the shipping performance (the growth of overseas fleet) in response to the growing overseas trade at all ports of India during the period (1999–2000 to 2008–2009), in terms of both a mathematical model and a graphical representation. Finally, it concludes that the absolute overseas trade, being highly import dependent, have led to a more or less stagnant performance in overseas shipping, owing to the lack of the adequate growth of absolute overseas exports during this period.     

北内环清管过程中清管球滞留问题研究

为保证北内环平稳、高效、安全输送天然气,对其进行清管通球。在清管过程中出现3次清管球滞留情况,针对这些滞留情况,从清管球在管道中的受力情况、清管球在三通处出现形状变化2个方面分析讨论了清管球滞留原因;从建立较大背压发球、增加清管球过盈量、改变三通倾斜方向3个方面来研究解决问题的方法,证明均不符合实际情况;通过对比清管球、皮碗清管器、泡沫清管器3种设备的优缺点,最后选择泡沫清管器为北内环清管最优的清管器材。     

江苏沿海港口吞吐量影响因素及预测分析

目前江苏沿海地区综合开发已上升到国家发展战略层面,沿海港口建设正在迅猛开展。港口吞吐量的预测对于港口的建设有着极其重要的意义。以港口和腹地之间的互动关系为出发点,分析了可能影响江苏沿海港口吞吐量的若干因素,采用主成分分析法提取了过去10年影响港口吞吐量的最关键因素,剖析了江苏港口发展的内在影响机理,并提出了基于影响机理的预测模型。最后使用模型对江苏港口吞吐量进行验证分析,模型为江苏沿海港口新一轮发展提供了有力的数据支撑。
