Modernos sistemas de propulsão

Abstract

Work devoted to descriptive system thrusters for boats . The systems are designed to meet the needs of the type of service and location that the vessel will operate . The harbor tugs , usually due to limited space for operation , requiring great maneuverability coupled with the traction force , the propellers are large diameter , so with blades large area , providing greater contact surface and higher mass displacements of water. In the case of modern harbor tugs have up azimuth thrusters , also known as rudder propellers . The offshore support vessels type PSV ( Platform Sup ply vessel ) are also adhering to this model of propulsion , but the focus in this are the conventional propulsion with variable pitch propeller . With smaller diameter and smaller area , th rusters in this case are not intended to higher static traction performance but speed, the nature of the operation of the vessel. Except in ships AHTS ( Anchor handling tug supply) , handling of anchoring systems platforms and also tugboats needing more traction. Each type of vessel has a propeller for its best development. Describes it this way each thruster with its features , advantages and disadvantages from the simplest to the present with its complexities . Key words: Thrusters. Vessel. Systems.
