Requisitos para modelo de operação da cabotagem de cargas conteinerizadas no Brasil: a utilização de terminais rápidos. / Requirements for operational model of short sea shipping of containerized cargo in Brazil: the use of fast terminals.

Valois, Nayara Amaral Lima de 07 October 2014 (has links)
Este estudo propõe requisitos para a adequação da operação de cabotagem de contêineres nos terminais portuários brasileiros. Esta adequação transforma os terminais convencionais em terminais marítimos denominados aqui como rápidos. O conceito de terminais eficientes utilizado pelo projeto europeu Motorways of the Sea - MoS serviu como referência para o desenvolvimento da proposta. A metodologia utilizada fundamentou-se na coleta de dados através de entrevistas semiestruturadas a usuários da cabotagem, além de questionário online com especialistas e simulação por eventos discretos da operação de cabotagem. As respostas das entrevistas direcionaram o estudo para fatores de melhorias relacionados a processos de liberação da carga por parte de órgãos de fiscalização, custos portuários e controles alfandegários. A avaliação das respostas do questionário online se fez por meio de uma variação da técnica Delphi com Q-sort que consolidou as respostas em cinco categorias: administrativo/fiscal, custos, hinterlândia, infraestrutura e operacional. O modelo de simulação de eventos discretos verificou os dados operacionais e avaliou as diferenças entre a operação dos terminais convencionais e de terminais compatíveis com o modelo do projeto MoS. Os principais requisitos propostos são: a melhoria no processo de fiscalização com a simplificação nas inspeções e liberações das cargas; a redução de fretes para transporte de carga porta-a-porta; a existência de acessos terrestres (rodoviário/ferroviário) para interconexões entre os modais; a disponibilidade de infraestrutura adequada (equipamentos) para uso nos terminais; e a minimização de tempos operacionais e de entrega porta-a-porta. Uma derivação da técnica Matriz QFD (Quality Function Deployment) foi utilizada para obtenção do sequenciamento dos requisitos propostos. O estudo verificou que a aplicação dos requisitos salienta as oportunidades de melhorias na operação de cabotagem nos terminais brasileiros. Também ficou evidenciado a possibilidade de adequação dos terminais convencionais em terminais rápidos, mediante a aplicação do sequenciamento obtido para os requisitos propostos. / This study proposes requirements for the adequacy of Short Sea Shipping (SSS) operation in Brazilian container port terminals. This adaptation transforms conventional port terminals into maritime terminals called \"fast\". The concept of \"eficient terminals\" of the European project Motorways of the Sea MoS served as reference for the development of this proposal. The methodology was based on data collection through semi-structured interviews with SSS users as well as an online questionnaire with experts and discrete event simulation of SSS terminals. The responses from the interviews directed the study to factors related to processes of cargo release by regulatory agencies, port costs and customs controls. The evaluation of the online questionnaire responses was done by means of a variation of the Delphi technique with Q-sort that consolidated the responses in five aspects: administrative, costs, hinterland, infrastructure and operational. The discrete event simulation model verified operational data and evaluated the differences between the operation of conventional terminals and those compatible with the MoS project model. The main proposed requirements are: the process improvement to reduce inspections and cargo clearances, the freight reduction on cargo door-to-door transportation, the existence of land access (road/rail) for interconnections between modes, the availability of adequate infrastructure (equipment) for terminal use and the decrease of operating times and door-to-door delivery. The Quality Function Deployment (QFD) matrix technique was used to obtain a sequencing order for the proposed requirements. The study found that the requirements application highlights the improvement opportunities in SSS operation in Brazilian terminals. It was also evidenced the possibility of conversion of these conventional terminals on \"fast\" terminals, with the requirements sequencing order application.

Les autoroutes de la mer / The motorways of the sea

Dang, Khanh Linh 25 November 2014 (has links)
Le transport intérieur de marchandises de l’Union européenne (UE) se caractérise par la domination du transport routier. En tant que mode le plus utilisé, le transport routier génère les coûts externes les plus considérables. Il est le responsable principal de la congestion routière et des émissions de CO2 qui sont les deux problèmes majeurs du système européen de transport de marchandises. Pour lutter contre ces deux problèmes, l’UE investit des fonds publics dédiés à la construction de nouvelles infrastructures afin d’augmenter leur capacité et de répondre à la demande de transport. De plus, elle favorise les solutions permettant d’alléger les trafics routiers comme le transfert modal d’une partie du trafic routier saturé vers d’autres modes moins polluants. Dans ce contexte, l’UE a promu les autoroutes de la mer (AdM). Nous avons analysé le contexte de développement des AdM, leur positionnement dans le système de transport et leur perspective de développement dans l’UE pour clarifier leur concept et étayer leur pertinence. En effet, pour répondre aux objectifs de l’UE de l’éliminer la congestion routière et de réduire les émissions de CO2, les AdM sont développées pour diminuer le trafic des poids lourds circulant sur les routes. Dans ce cas, la technique du navire roulier permettant de transporter des poids lourds semble adaptée. Les AdM constituent un nouveau parcours pour la construction d’itinéraire d’acheminement des marchandises des transporteurs routiers. Elles offrent une solution moins couteuse que le « tout routier ». En utilisant les AdM, les transporteurs routiers peuvent réduire les émissions de CO2 dues à leur activité grâce à la diminution de la distance routière parcourue. Ainsi, les AdM constituent un mode de transport complémentaire du transport routier. Dans le cadre de la France, les trafics routiers de marchandises se composent d’une part important des flux de transit. De plus, à cause des obstacles naturels à la frontière tels que les Pyrénées, les Alpes et la Manche, les flux de transit se concentrent sur deux axes routiers principaux : l’un, du nord au sud de la France et l’autre, à bord de la Méditerranée. En favorisant le transfert modal de la route vers la mer, la mise en œuvre des AdM permet d’alléger les trafics sur ces axes. Dans ce contexte opérationnel, les ports jouent ainsi un rôle important. Situé au nord de la France, le port du Havre serait impliqué pour alléger le trafic routier du nord au sud de la France. Ainsi, nous avons étudié le cas du port du Havre pour évaluer la possibilité de ce transfert modal. / The inland freight transport in the European Union is characterized by the domination of road transport. As the most used, road transport generates the most significant external costs. It is primarily responsible for traffic congestion and CO2 emissions which are the two major problems of the European system of freight transport. To fight against these problems, the EU invests public funds dedicated to the construction of new infrastructure to increase capacity and meet the demand for transport. In addition, it promotes solutions to alleviate road traffic as a modal shift from road traffic saturated to less polluting modes. In this context, the EU has promoted the motorways of the sea (MoS). We analyzed the development context MoS, their position in the transportation system and development prospect in the European Union to clarify its concept and its relevance. In order to meet the objectives of the EU to eliminate congestion and reduce CO2 emissions, MoS are developed to reduce the heavy vehicle driven on the road. In this case, the technique of rollon/ roll-off to carry heavy weight seems appropriate. MoS are new routes for the construction of routings goods hauliers. They offer a less expensive than the "all roads" solution. Using MoS, hauliers can reduce CO2 emissions thank to reducing the roadway travel. For this reason, the MoS are a complementary mode of road transport. In France, road freight traffic accounts for a large number of transit flows. Also, the number of border crossings is limited due to natural barriers of the Pyrenees, the Alps and the English Channel. Congestion is therefore serious on two main roads: one from north to south of France and the other go along the Mediterranean Sea. Promoting modal shift from road to sea by the implementation of MoS, part of the traffic of these axes and points of saturated transition could be carried over the sea. Ports thus play an important role to make the shift from land to sea. Located in northern France, the port of Le Havre can be involved to ease the traffic from north to south of France. We studied the case of the port of Le Havre to assess the feasibility of this modal shift.

Les autoroutes de la mer : aspects juridiques / Motorways of the sea : legal aspects

Happi, Alvine Bélise 28 September 2015 (has links)
Dans une perspective de réalisation du marché unique européen, la libéralisation des différents secteurs d'activités en Europe dont celui des transports au courant des années 1990, entraîne le développement des différents modes et une surcroissance du transport routier avec certes de réels avantages en terme de développement économique, de compétitivité et d'emploi, mais aussi de sérieux inconvénients : congestion des grands axes routiers et augmentation du taux d'émissions de C02. Encourager l'intermodalité et promouvoir le développement des modes alternatifs à la route, rééquilibrer les différents modes de transport, constituent désormais l'une des principales priorités de l'Europe. Sous les auspices du Livre Blanc de 2001 relatif à la politique européenne des transports, les autoroutes de la mer naquirent sous un jour insuffisamment éclairé, et, actuellement, elles essaient de se frayer un véritable chemin. Elles présentent néanmoins des caractéristiques essentielles : considérées à la fois comme des infrastructures et des services de transport, elles constituent des lignes régulières de transport maritime à haute fréquence et à haute qualité de service, assurant des liaisons entre deux ou plusieurs ports d'au moins deux États membres de l'Union Européenne. Issues de la nouvelle politique européenne des transports, elles répondent aux impératifs de décongestion des grands axes routiers saturés, de sécurité routière, de développement durable et de protection de l'environnement, favorisant ainsi le développement et la croissance du marché intérieur. Or, l'absence d'un statut juridique initial applicable aux autoroutes de la mer a de réels impacts sur l'émergence de ce concept, qui évolue en s'adaptant aux nouvelles contraintes, en relevant de nombreux défis. Le bilan actuellement mitigé des autoroutes de la mer en Europe conduit à s'interroger sur les perspectives de leur pérennisation. Dès lors, notre réflexion est orientée vers deux aspects juridiques essentiels. D'une part l'impact réel de l'absence d'un régime juridique initial sur l'émergence des autoroutes de la mer et sur les mécanismes de financement qui l'accompagnent. D'autre part, la détermination d'un cadre juridique favorable au développement des autoroutes de la mer dans une perspective d'assurer leur meilleure intégration dans la chaîne logistique globale, et leur émergence comme véritable alternative durable, crédible et efficace à la route intégrale. / With the prospect to achieve the European single market, liberalization of various sectors in Europe including transport in the 1990s decade, leads to the development of different means of transport and the increase of road transport activities, certainly with real benefits such as economic development, competitiveness and employment; but also serious drawbacks : congestion of highways and increase in C02 emissions. Encouraging intermodality and promote the development of road alternatives, adjusting the balance between means of transport, is considered as one of European Union key priorities. Under the auspices of 2001 White Paper European transport policy, Motorways of the Sea concept were insufficiently informed, and currently, looking for his own way. Nevertheless they do present essential characteristics: both transport infrastructures and services, Shipping line services which are regular, frequent and of good quality , inbound to two or more sea ports to at least two states member of European Union. From the new European transport policy, they meet the requirements : road safety, sustainable development, safe environment, promoting growth in European Union internal market. However, the absence of an initial legal status applicable to the Motorways of the Sea has a real impact on the emergence of this concept, which evolves by adapting to new constraints, raising many challenges. The current mixed picture of Motorways of the Sea in Europe raises questions about the prospects for their sustainability. Our focus is directed towards two key legal aspects. On one hand the real impact of the absence of an initial legal status on the emergence of motorways of the sea and the funding mechanisms that accompany it. On the other hand, the determination of legal framework favourable to the development of Motorways of the sea which will contribute to a better integration into the global Supply Chain and emerge as truly sustainable alternative, credible and effective to the integral road transport.
