A construção naval no Brasil

Abstract

Initially, we understand that a vessel is a buildin g whose purpose is to navigate, both at sea and in lakes, river, regardless of size, for m of propulsion, function or construction material. The vessels are divided in s everal types, boats, ships, boats, etc., and these are further subdivided into groups, subgroups families, etc. based on numerous criteria.A evolution of vessels from the p irogue (dug trunk) and the ferry (tie trunks) to modern tankers had fundamental impo rtance in the progress of civilizations and cultural exchange between people the design of these vessels is only possible with the analysis of key structural e lements to any type of vessel. It is the naval engineering definition of the structure o f a vessel, the distribution of all components and the design, installation and operati on of their equipment. The planning of the structure and components of a vesse l has become increasingly complex due to the automation of navigation control s and thrusters instruments, refrigeration and others. Thus, modern naval engine ering is not limited to perfect methods of building ships, but is actively engaged in the development of automatic maneuvers and navigation devices such as the autopi lot, which maintains the course and eliminates the permanence of the helmsman in co ntrol of the vessel. Transatlantic modern and large tonnage tankers also have a wide infrastructure Maintenance’s foundation of shipbuilding; however, remain unchanged since it started using the metal. They include the shape of the hull, the general distribution of internal volume of the vessel and defining the cros s section. The work develops the history of shipbuilding in Brazil, with its product ion processes over the decades. It shows the development of the shipbuilding industry and the importance of the shipbuilding activity to the economic sector. Ratif ies with publications in newspapers the current situation of the shipbuilding market th at is experiencing difficulties, due to the economic instability of Petrobras, causing seve ral resignations and the freezing of shipbuilding.
