Propulsão Elétrica em embarcaçõe off-shore

Abstract

Propulsive systems are fundamental for any vessel, since they are responsible for the displacement of the vessel. Therefore, with the resumption of the world economy, it is necessary to analyze the feasibility of each propulsive system, such as its operational cost and its function, so that it is suitable for each specific type of vessel. Offshore vessels require a propulsive system that provides them with the possibility of flexibility and maneuverability, as well as assisting in dynamic positioning. According to the literature analyzed, there are three different types of propulsive systems in these vessels: Mechanical Diesel System, Electric Diesel System and Hybrid System. The research, therefore, has the purpose of analyzing, through the exploratory, theoretical-bibliographic research, the reason why the Electric Diesel system should be inserted with greater incision in these types of vessels. Thus, the research has the main objective to evaluate the feasibility and efficiency of the electric propulsion systems with the purpose of the advantages of its implantation in offshore support vessels. For this purpose three support specificities are used: I). Describe, through historical and technological perspective, the evolution of electric propulsion; II). Picture the types of naval and offshore propulsion systems; III). Discuss the advantages of electric propulsion. It was understood that the reduction of fuel and noise, existing in the electric diesel propulsion system, promotes a continuous search so that the operational costs are reduced, that is, the minimization of the costs is fundamental and primordial in the adoption of this system for the boats PSV and AHTS.
