The high voltage power supply (10 kV/50 Hz/2 000 kVA) for the quay cranes is used for the power input of the system, after frequency and voltage converting (450 V/60 Hz), then putting out and supplying to vessel. This system is flexible with positive effect on energy-saving and emission reduction; besides, there's no requirement of civil reconstruction to container terminals, which is suitable for the busy ports in China.展开更多

The Korean container port development under the master plan for national port development reveals a severe problem of excess supply of port facility in some ports. This paper, the authors analysed the second and the third master plan for national port development implemented in 2001 and 2011, and a revised plan in 2006, along with the amended predictions for container throughput. Furthermore, the effectiveness of the implementation of the initial plan, and the current situation of South Korea＇s main container ports of Busan, Gwangyang, Incheon, and Pyeongtaek ＆ Dangjin was examined. Through the analysis of port vitalizations, we have examined the actual problems for the prediction of container throughput. Also, this research analysed the functional difference of each port and organized the function of each one discriminatively. Therefore, identifies the problems, which arise with making the container throughput forecasts, which is a fimdamental aspect of existing port development policy, and suggest a direction for future port development by synthesizing the results of analysis.展开更多

Data collected for 6 years （2009-2014）, HHI （Herfindahl-Hirschman index technique） was used to analyse the market behaviour and the movement of the market towards monopoly or to lead to PPC （pure and perfect competition）. Based on the above, by analyzing the defined market data, it was found to be a promising market and tends to competition. Of course, this serves the interest of the client, which is the efficiency and speed of cargo handling safely and at the lowest cost.展开更多

This paper initially introduces risk assessment approaches within the emerging role of ports Thereafter, it qualitatively assesses their potential for ports by discussing issues challenging every safety and security approach within the maritime industry such as proactiveness, organization, transparency, cost-effectiveness and, when possible, calibration to specific experiences. Moreover, an empirical study was conducted in order to provide evidence for formal risk assessment for safety and security in the main Greek port container terminals of Piraeus and Thessaloniki. The empirical research is based on in-depth semi-structured interviews with the administrations of container terminals. The results include important findings, regarding the likelihood of appearance of certain risks and their perceived severity in Greek container terminals. The collected answers and their analysis are also important for confirming the suggested theoretical formal risk assessment framework for ports.展开更多

At the same time literature in port economics and management has proposed various means for analyzing market conditions, overcoming competitive pressures in the port industry and pursuing sustainable competitive advantage. In line with this discussion, albeit with a significant time delay, port economics and management literature has also proposed the use of marketing strategies as a strategic tool towards achieving port competitiveness. However, the early approaches to port marketing, mainly based on consumer marketing principles, where followed by scarce references, mainly dealing with particularities of marketing implementation in ports and terminals. This paper attempts to provide a solid theoretical background to the notion, the need and the applicability of the marketing concept in the container port industry. It investigates the preconditions under which port marketing strategies are designed and formulated, by measuring the level of market orientation of ports and terminals. Furthermore, it attempts to examine the impact of market orientation on port performance, under the mediating role of marketing tactics and the moderating effect of the ports＇/terminals＇ internal and external environment.展开更多

The aims of innovations are to decrease required power of construction （in particular, piling） equipment and, correspondingly, to improve environmental situation at the construction site. Another achieved goal is providing long tubular piles installation in hard soils conditions without application of very heavy and powerful driving machines. Worked out solutions are based on two approaches. One of them provides separate loading of driving force on pile＇s shaft and pile＇s tip concentrating the whole driving force on one of the mentioned parts of the pile. Another approach is focused on prevention of soil plug formation inside of the tubular pile tip facilitating the pile installation process. Also improved anchorage system for sheet piling seafront walls is presented and discussed. All considered innovations are patented and can be used in wide range of marine, offshore, coastal and harbor structures.展开更多

An approach based on both panel data and multi-inputs/outputs is considered comprehensively, and aims at measuring the operating efficiencies of 10 leading container ports in China from 2001 to 2006 by applying this new systematic influence factor of total factor productivity change is the calculation method. The results illustrate that the main technology change, and the container transportation of these 10 ports is on the healthy development status and will recover and grow reposefully in the following years展开更多
