Ⅰ. Shipping After entering into the 1990's, the ship-building industry, badly affected by the long recession of the world shipping market, has been growing very slowly, while the competition has been a fierce one. From the shares enjoyed by the major shipping countries in the world, we can see that the first one is Japan which occupied 38%; South Korea came to the second,obtaining 15%; the third is Germany, being 8%. The shipbuilding industry in America is shrinking, owing to the high cost of production. Up to 1993,Japanese ship yards had still been in difficult situation, and many Japanese ship owners would rather order new ships from South Korea because the rising value of Japanese yen made it expensive to build in domestic yards. Nowadays, Japanese shipbuilding industry is exposed to the problem of scarce of labour force. The Korean shipbuilding industry, whose  相似文献

The simulations performed show that demand for quality tankers has to increase by 30% for a two-tier tanker market to emerge. The two-tier freight structure will only last for 3–5 years due to contracting induced by higher freight rates. This means that OPA does not by itself result in higher freight rates for tankers that comply with the requirements. If Western Europe also closes their trades to substandard tankers, a two-tier market emerges and quality tankers obtain a premium. The paper presents a simulation model for international tanker markets. The non-linear complementary equilibrium model solves for a sequence of static equilibria in segmented tanker freight markets, shipbuilding and scrapping markets. Freight markets are segmented according to quality requirements for tankers. The model specifies three tanker classes and one—quality tankers—can operate both market segments.  相似文献

A rather significant number of business entities already operate within (or, have considered to exploit) the Arctic region, focusing upon previously untapped resources such as precious minerals and large quantities of oil and gas; touristic and fishing activities are clearly on the rise, with various endeavors of maritime transport also being put forward. Up until recently, harsh year-long environmental conditions have significantly hindered the necessary access and transport connections in the Arctic. Even in the case that weather conditions did permit vessels’ passage, unreliable navigational aids and lack of infrastructure/support provided obstacles difficult to overcome. However, environmental data recorded during the last couple of decades clearly indicates that there is a continuous decline of ice coverage in the “High North.” Given this steady decline, the Arctic has now been viewed as a promising field for economic activities and is considered as a potential connecting corridor between Asia and Europe/America (and vice-versa). As human presence and operations are expected to intensify there, it is of utmost importance to evaluate the current level of support towards ships that will be crossing the region; capabilities in relation to search and rescue (SAR) operations and oil spill response are also important. The analysis in hand will first deliver a discussion of the so-called Arctic Passages. While various different maritime routes have been proposed in relation to the Arctic, the most promising one, the Northern Sea Route (NSR), will provide the epicenter of discussion. Through an extensive literature review that includes numerous internet resources, the current analysis will identify the numbers of icebreakers already operating in the NSR, as well as those that will be commissioned into service in the near future. The choice to research the specific type of vessels is supported by a simple argument: icebreakers currently are and will continue to be in the foreseeable future the main “tool” to support shipping activities in the Arctic. Furthermore, emergency management capabilities in the Russian Arctic will be examined to include the current state of rescue coordination centres along with the availability of SAR assets. Additionally, the efforts thus far by the Arctic Council to increase coordination and interaction among the States involved in Arctic affairs will be summarized; the latter will be achieved via a brief review of a very important legally binding agreement: the “search and rescue” instrument. In conclusion, the Russian State has already heavily invested in icebreakers’ building and their current number is fully capable to handle the present level of limited traffic. On the other hand, ships are currently faced with long distances to cross (often without adequate support) adverse environmental conditions, unpredictable hurdles, and slow response times in case of an emergency. Therefore, in case ships operating in the region are increased, it will be difficult to deal with all the additional demands for support. Of particular interest is the fact that considering the vast area of the NSR, the overall available response capabilities in the region under discussion are rather thin; any further increase of maritime traffic in the “High North” must be balanced with additional strengthening of emergency management capabilities. In any case, should the NSR become fully integrated in the global maritime transport system, Russia’s geopolitical status will be clearly improved and further research is needed to discuss the implications both at the regional and global levels.  相似文献

Intelligent unmanned system combat is moving from concepts to actual combat applications. The military applications of intelligent unmanned systems are emphasized by focusing on the needs of the combat missions that they will undertake on future battlefields and summarizing the development statuses of land, air and maritime unmanned systems. Aiming at the key problems faced by intelligent unmanned systems and the practical difficulties that will be faced on the battlefield in the future, we analyze the key technologies required for intelligent unmanned systems, including autonomous perception and understanding in complex environments, behavioral decision-making and trajectory planning, autonomous navigation and positioning, multi-scenario autonomous skill learning and intelligent control, unmanned cluster cooperative control, natural human-computer interaction, etc. At the same time, aiming at the problems that will be encountered in the further development of intelligent unmanned systems on the battlefield in the future, we start with individual enhancement and cluster enhancement, and conduct a detailed analysis of the development trends of intelligent unmanned systems. © 2022 Palaeobulgarica.

The economic value of the oceans and maritime industry is strongly gaining in importance. As the oceans are very large and particularly sensitive ecosystems, which need to be preserved, a balance between the use and the protection of the seas has to be found. On this issue, the paper presents some thoughts starting with a brief analysis of what to understand by maritime industry which is labeled as blue economy, and a recapitulation of the main threats for the marine environment, caused by blue economy. After that, some noteworthy prerequisites and criteria for finding a sound balance between the use and the protection of the seas will be highlighted, especially the need for sustainable ocean governance is put to discussion.  相似文献

On the basis of the principle of dieless hydrobulging technology, a novel hydrobulging technology for manufacturinghyperbolic plates is proposed. First, a toroidal pipe elbow or a partial toroidal pipe elbow is formed, then the single hydrobulgedstructure can be cut up into some desired plates. It is proved by experiments and finite element simulation that manufacturingtechnology of hyperbolic plates adopting integrated hydrobulging forming technology is feasible.  相似文献

China’s Belt and Road (BR) initiative is expected to facilitate international trade between the countries involved. In this study, we review the special requirements of wine logistics and the market growth potential of wine consumption in China. A model minimizing generalized logistical costs is developed and applied to wine imports in China, so that the best candidate cities in which to locate transport gateways and distribution centers can be identified. Our analysis suggests that the most preferred gateways are Shanghai, Tianjin, Guangzhou, and Hong Kong, which all have similar delivery costs. In comparison, Beijing and Chongqing have much higher delivery costs, mainly because they do not have good access to marine transport and/or efficient domestic distribution networks. For long-distance intercontinental transport of large volumes of wine, marine shipping remains the only viable delivery mode. However, wine distribution within China extensively uses air, road, and water transport. Therefore, cities with excellent multi-modal transport services are better positioned to become wine logistics gateways. Our study also highlights the importance of value-added services and good government support, which are important factors that influence distribution costs and quality.  相似文献

The introduction of unit load methods, particularly the cellular container system, has been associated with a large increase in ship size on some of the world's major general cargo routes. In this sector, ship size is determined by a set of interactions between handling performance, route length, traffic flow, itinerary, requirements for frequent and regular service, port costs and general system organization. This paper explores these relationships to identify major influences and to consider the prospects for further growth.  相似文献

The Polish economy is going through fundamental changes from a central planning to a market economy. The main aim of this transition is the privatization process which has to change the structure of Polish economy. Privatization has to establish more favourable ways of utilizing the productive capacity of state enterprises and create better conditions to compete on the market. The Privatization process for Polish state enterprises was defined in the Act on the Privatization of State Enterprises of 13 July 1990. According to this Act state enterprises can be privatized in capital or liquidation methods. The capital method has been applied to the privatization of Polish ports. In 1991 the major Polish ports were transformed into a State Treasury shareholder company. The holding company was used in the first stage of privatization. Gdynia was the first port which started this process building the real model of holding. Another important element connected with the structural transformation of Polish ports is the separation of operational and management roles. According to the Act on Ports, the Port Authority is also responsible for the development of the commercial, industrial and distribution services. This Act will also enable Poland to adapt economic and legal regulations which are similar to those in the European Union ports.  相似文献
