In a previous paper on Canal management we examined the treaties and regulations underpinning firstly American and later Panamanian administration of the Canal. We also looked at the transfer of the Canal into Panamanian hands, including the management models used, ending with a review of toll structures and results. The subject of this paper is the operation of the Canal and the heated debate surrounding its modernisation, with a view to determining the adequacy of projected plans, as well as any future requirements, for maintaining its capacity in the 21 century. This paper seeks to analyse the Canal's operation, modernisation programmes and traffic systems as well as its key element: human resources. 相似文献

Two major components of the Panamanian economy are its maritime sector and the Canal. The author covered the analysis of the former in a previous paper. For a rigorous study on the future capacity of the Canal, it is required, on the one hand, that an analysis of its management be done and, on the other hand, of its operation, modernisation and future scope. This paper focuses on the Canal management since its creation, reviewing its historical background, legal foundations, as well as its management and toll system currently in place—which is the responsibility of Panama nationals, once the Canal was transferred by the USA. Present management indicates optimum performance and outstanding improvements. It is successfully facing the challenge of maintaining the operating capacity to accommodate future world traffic. Its operation, traffic and modernisation will be the subject of our next paper. 相似文献

Spain’s port system was subjected to significant legislative reforms during the 1990s. Spanish Law 62/97 allowed regional governments to manage commercial ports, whereas the central government continued to control the main organisation in charge of the Spanish port system – the Spanish National Ports and Harbours Authority (SNPHA). This paper analyses the evolution of maritime traffic to measure the possible costs of political coordination between the SNPHA and the port authorities controlled by various political parties that rule regional governments. The findings point to coordination costs having a limited effect on the evolution of maritime traffic. 相似文献

Compliance with international emission regulations: Reducing the air pollution from merchant vessels
In September 1997, the International Maritime Organization (IMO) adopted an international convention protocol to reduce air pollution from ships, in order to achieve sustainable maritime development. This protocol has been approved by 15 member countries and will be enforced in May 2005. Pollutants emitted from ships, such as nitrogen oxides, volatile organic compounds, sulfur oxides, etc. will be regulated by this convention through ship inspections and issuance of certificates. Ships belonging to maritime countries such as Taiwan, which sail around the world and berth in commercial ports, must obey this convention. This study has investigated possible strategies, which may be adopted by maritime countries to conform to this IMO convention in order to reduce the air pollution from ships. A sea-going ship must prepare EIAPP and IAPP certificates for inspection by port-state-control officials, when the ship is anchored at a maritime port. These port-state-control officials may also require the continuous detection and sampling of a ship's emissions, while it is berthed at the port. Legislative support is necessary for successful implementation of these safeguards. It is suggested, therefore, that the administration of both navigational and environmental protection, in maritime countries, cooperate in the revision of relevant federal laws, to implement the provisions of the MARPOL 73/78/97 convention; in this way, the air pollution from ships can be effectively controlled. Installation of advanced detection equipment can effectively detect any ships’ violations of air pollution regulations. The Harbor Affairs’ Bureau should also establish a database of air pollution inspections for ships berthed within their harbor, requiring that ships’ equipment comply with the requirements of the MARPOL convention, for the reduction of air pollution. 相似文献

The South West of England is a very extensive region, with constraints in terms of its transport network. It is imperative if the region is to optimise its economic development for transport services to fully utilise all transport modes, not least, short sea shipping. To achieve this objective will require, inter alia, investment in the region’s port infrastructure. The result of this study suggests that each South West port provides a hub to develop a small maritime cluster which provides some sort of platform for marine and maritime related activities or businesses to co-ordinate and communicate. In addition, the region is well placed geographically in relation to a number of other European Union countries, with which to develop seaborne trade links. If this can be supported both by the development of coastal shipping links between regional ports and the incremental capability of rail and road transport within the region, then substantial increased economic activity for the region could result. Moreover, it would be beneficial if the region’s ports could act as a maritime cluster, optimising the contribution each port can make. This in no way would preclude healthy competition between the ports. 相似文献

This paper presents the current Environmental Impact Assessment (EIA) system for Thailand. The steps of the EIA approval and procedures are summarized. More particularly, the study focuses on port developments. Guidelines, prepared by the national authority, are presented that help EIA practitioners to prepare EIA reports for port projects. The EIA for the Ranong port in Thailand was selected as a case study because of its recent approval as well as its reflection on political intervention. Special attention was given to marine physical aspects in order to demonstrate types of marine physical concerns, assessment methods used, and corresponding environmental measures established. Changes in water current and elevation, sedimentation, large waves and bank erosion, maritime accidents and related oil spill were included. Finally, the strengths and weaknesses of Thailand’s EIA system were discussed. 相似文献

In 2008, 55 of the world's largest ports voluntarily adopted the World Ports Climate Declaration (WPCD) and the International Association of Ports and Harbours committed to long-term work on implementation through the World Ports Climate Initiative (WPCI). This article assesses the work of WPCI since 2008 and makes five recommendations that, if implemented, could support efforts to reduce the climate and environmental impacts of port operations and international shipping. In particular, as the impetus for the WPCD came from a port city – Rotterdam – and their engagement with a transnational municipal network – the C40 Large Cities Climate Leadership Group – the paper considers the role of cities and transnational municipal networks in governance, and the potential for cities to play a more active and influential role in the maritime sector. The article presents an overview of literature on the role and function of transnational municipal networks, the background and development of the WPCD, analysis of the work of WPCI, and a discussion concerning the potential of cities and transnational municipal networks to support and add value to WPCI or similar initiatives in the maritime sector. This informs the conclusions and recommendations to marine policy-makers and port stakeholders. 相似文献

Against the backdrop of Indonesian President Widodo's expressed intention to turn his country in to a maritime nation again, this article examines the way in which the Indonesian state understands and utilises the concept of maritime security. The article achieves this aim by discussing the results of a Training Needs Analysis of key Indonesian state maritime security actors, conducted as part of the first phase of a multi-stakeholder project examining how Indonesia's maritime security capacity can be improved.The article illustrates how key maritime actors within the Indonesian state demonstrate a diverse understanding of what maritime security is, and argues that there is a demonstrable willingness on their part to look beyond a narrow conceptualisation of security in the maritime domain, which is solely focused on military threats and the defence of the state, towards something more comprehensive. Here the Indonesian approach to maritime security mirrors in practice conceptual trends encapsulated in the emergence of maritime security studies. The article concludes that there is the potential for a more comprehensive maritime security agenda to take hold in Indonesia but that this will require continued strategic and policy focus on the maritime domain within the country, alongside an emphasis on partnership building both within the state and between the state and non-state actors.Consistent dialogue around how maritime security is conceptualised would be helpful in supporting these two conditions the article posits, elaborating the value of the human security lens for those interested in a more comprehensive approach to maritime security. 相似文献

The air pollutant emissions of the ships at port represent a small percentage of the overall emissions from shipping however they are concentrated in a small area. In Mytilene, Lesvos, the port is located within the city limits, resulting in air pollution, congestion and noise, especially during the tourist season. The aim of this study is to estimate the quantities of particulate matter and CO2 emitted by ships in the port of Mytilene and to explore the potential of shore side electricity to reduce the emissions. The emissions were estimated using the bottom–up methodology, based on the activity of the ships in the port (berthing, maneuvering). Simulation of renewable energy sources was made using Homer Energy microgrid simulation software. The results showed that between the 10th and 20th of August 2012, there were 40 calls of passenger ships, tankers and bulk carriers in the port of Mytilene, emitting 441 kg of PM10 and 282 metric tonnes of CO2. About 63% of PM10 and 77% of CO2 were emitted at the berthing phase and the remaining during the maneuvering. These emissions could be reduced by providing electricity to the ships from a hybrid renewable energy system with wind turbines and photovoltaics, connected to the grid. Simulations showed that the total energy requirements of the ships in the port of Mytilene could be covered by four 1.5 MW wind turbines combined with a 5 MW photovoltaics. With this configuration, renewable energy will exceed the ships' electricity needs for most of the time in order not to increase the power station's load. The excess energy could be fed to the islands' grid, so a costly battery storage system is not necessary to handle the variations of alternative energy. In this way, a considerable reduction of the CO2 and PM10 emissions by the ships in the port occurs, providing a viable solution for a cleaner and healthier environment. 相似文献

Adopting a critical geopolitics approach that accounts for the mutually reinforcing link between geo-informed narratives and projection practices, this article proposes that ocean governance and maritime security have translated into states' and regional organisations' increasing control over maritime spaces. This leads to a certain territorialisation of the sea, not so much from a sovereignty and jurisdictional perspective but from a functional and normative perspective. The article starts by discussing the ways oceans have been represented and shows that they are far from a placeless void, both in practice and in discourse. The article then frames the analysis of ocean governance and maritime security within critical geopolitics, and elaborates on the case of the European Union's narrative and practice. It concludes on the mutually reinforcing link between discourse and practice in the field of ocean governance and maritime security in general, and on the consequences for the EU in particular. Scholars working on ocean governance and maritime security are encouraged to challenge the traditional view that oceans are placeless. 相似文献

The 2004 enlargement of the European Union (EU), as well as the further enlargements planned from 2007 onwards (Romania, Bulgaria, Croatia and Turkey), entail changes of a geo-political nature that not only imply an increase in size (a rise in the number of States, new boundaries), but, more especially, also involve a shift in the EU's maritime status, with its projection towards the Atlantic now being checked by a swing towards continental Europe and its inland seas. In view of the new political map being drawn up, two questions beg to be asked: to what extent is Europe's maritime condition being strengthened; and, does the new maritime Europe constitute an opportunity, or does it aggravate the already-existing problems and threats? 相似文献

A new federal administration, alongside initiatives proposed by the President's US Commission on Ocean Policy, provides a timely and critical opportunity for maritime archaeologists and cultural resource managers to re-consider management frameworks for maritime cultural heritage in the USA. Policy is urgently needed that defines governments’ roles and responsibilities in protecting and managing maritime cultural heritage in federal waters. Implementation of a regional governance structure based on the tenets of ecosystem-based management is proposed in this paper to manage and develop these resources effectively. Through regional governance, the maritime heritage of the USA can be conserved for future generations, keeping its citizens connected to deep-rooted maritime traditions and contribute to the well-being, economic growth and development of coastal communities. 相似文献

Investigation of strategies to improve the recycling effectiveness of waste oil from fishing vessels
The marine ecological environment and fishery resources can be severely polluted or destroyed by waste oil from fishing vessels if they are emitted directly into the ocean without any proper pre-treatment process. International conventions such as MARPOL 73/78 regulate waste-oil emissions and require the installation of a waste oil–water separator only for ocean-going ships of over 400 gross tons. Hence, these international conventions are not applicable to most fishing ships due to their low gross tonnages. In addition, space on most fishing vessels is too limited to allow waste-oil storage tanks or a waste oil-water separator to comply with international maritime regulations. Because a significant amount of waste oil is produced by fishing vessels around the world every day, effective strategies or measures are needed to prevent this waste oil from polluting the marine environment. This study thus investigates strategies and measures for improving the effectiveness of waste-oil collection from fishing vessels. This study found that existing procedures for the collection and treatment of waste lubricating oil on land could be applied to the management of waste oil and bilge water from fishing vessels. Sufficient oil–water separators and storage facilities for the collection of waste oil should be placed at each fishing port and shipyard. Fishermen should then be required to deliver their waste oil to these storage facilities, from where it can be transported to legal recycling companies for further treatment. In addition, fishing harbor authorities should bear definitive responsibility for monitoring the illegal dumping of waste oil and for checking the waste-oil record books of fishing vessels. Each maritime country should enforce relevant laws and regulations to reduce the emission of waste oil from fishing vessels into the ocean. 相似文献

The Panama Ship Registry has its origins in the year 1917. Nowadays, Panama has the largest vessel registry in the world. The second placed registry in the world ranking is Liberia, which does not have even half the number of Panamanian ships. In this Centennial, the aim of this paper is to analyse the evolution of the Panamanian Registry, the structure of the Panamanian-flagged fleet and the level of compliance with international standards in relation to maritime safety and working conditions. To undertake the analysis, two different qualitative and quantitative approaches are compared and integrated for the evaluation of the Panama Ship Registry: the degree of ratification and enforcement of the Conventions and Recommendations of the International Maritime Organization and International Labour Organization, and the results of Panamanian flagged vessels in inspections carried out within the major Port State Control Memoranda of Understanding. This paper fills a research gap by discussing an approach to the concept of flag of convenience and flag State, Panama is more an international registry, whose role is becoming less important from the points of view of safety or working conditions. The fleet performance evolution has been very positive as evidenced by the data presented in this article regarding Port State Control. 相似文献

In this study, we propose a fuzzy approach in order to evaluate the maritime risk assessment applied to safety at sea and more particularly, the pollution prevention on the open sea. The work is based on the decision-making system, named MARISA, presented in Balmat et al. (2009). This system allowed defining a risk factor for each ship according to ship’s characteristics and weather conditions. In this novel paper, the proposed system takes into account the ship speed evolution and the ship position with respect to maritime shipping lanes is developed. To validate the method, we present an example of results with real data. 相似文献

Recent changes in marine policy in Panama are closely related to sustained expansion of the Panamanian economy in the past ten years. Important drivers of economic growth such as the Panama Canal expansion, tourism, and real estate development directly involve marine and coastal areas. Therefore, maintaining the quality of these environments, as well as the sustainability of the human communities that depend on them, calls for the implementation of adequate management and planning policies. In light of a complex history of marine and coastal policy in Panama, current institutional restructuring processes, and a growing recognition of the importance of marine and coastal geographies, the authors aim to document the current status of, and community response to, marine and coastal policy in Panama, analyzed in terms of three important cross-cutting sectors: tourism, fishing, and conservation. To do so, the authors introduce two case studies: one in the Pearl Islands Archipelago and one in Bocas del Toro, each with varying degrees of participation or involvement in each sector, to illustrate the range of adaptations to change occurring in coastal communities. Based on an in-depth policy analysis and the case studies, the authors suggest that there are important administrative and structural gaps in the legislation and institutions that enforce them, as well as a lack of integration across institutions. In particular, the authors highlight the lack of clear marine and coastal property regimes as an obstacle to the implementation of integrative marine policies in Panama. 相似文献
