collaboration?After defining the general maritime exportation mechanism, it is observed that it is very comprehensive, comprising several variables and requiring updates regarding volumes, capacity of the ships, prices, maritime fees, fees, law, among others. One point to be discussed is how the exporter companies involved in this mechanism shall act: individually or in collaboration? If isolated, each exporter company shall analyze the best manner to perform the transport of its goods, analyzing the existent navigation companies, fees, acceptable volumes, transport mode of the goods and the proper port, as well as preparing the required documentation.One possibility to begin collaboration is searching for help from a professional prepared to perform such activities, the freight forwarder to undertake, if possible, the joining of loads of other clients in order to achieve scale savings. It can be also performed directly through partnerships among exporter companies, with no contracting of this third party. Regarding shipowners, the collaborative transport can be also performed if a certain shipowner does not have sufficient volume to fulfill a ship, joining with others and sharing expenses and gains. Such alliances are under constant transformation, altering its members to adjust to market instabilities or to expand services; those can look like instable associations in a first moment, but are actually flexible and eliminate more fragile competitors, expand the service coverage, enhance efficiency, punctuality and speed. Through this collaboration in the transport it is observed the formation of global logistics networks articulating productive areas, not only expanding service coverage but also frequency, efficiency and circulation rate of the goods (Souza, 2009).The following item shall approach CTM, in order to explore this new logistics concept and trying to apply it in logistics chain of exportation of manufactured products through waterway mode. 3. CTM contextualizationConsidering that the Brazilian GDP was correspondent to US$ 1.99 trillion in 2008 and that the percentage applied to logistics is of 12%, US$ 238.8 billion were invested in logistics costs this year. It can be stated that US$ 143.28 billion were addressed to costs with transports, which means, about 7.2% of the domestic GDP, a value much higher than the value applied in developed countries such USA, applying only 4.8% of the GDP in transportation. It shows that the transportation is a significant item in final accountability of resources spent on Brazilian products, either for the domestic market as for products to be exported, composing Brazil Cost (Tacla, 2003).One manner to reduce the existing problems in logistics is trough collaboration applied to transportation between the several agents of a logistics chain, adding value to the whole process. It is also valid to mention that, for more benefits, the CTM shall act in the interaction of several logistics chains, forming the concept of logistics network. For Tacla (2003) the collaboration is performed through sharing of resources, mainly in the use of the same transportation equipment, contributing for the reduction of costs by enhancing the productivity of the transportation equipment. Therefore, the beginning of the Collaborative Transportation is the preparation of a shipping prevision, including the generation of orders and loads and,
