O sistema de posicionamento dinâmico nas embarcações mercantes: topologia e operação

Abstract

Vessels move on three axis. These movements can be controlled two ways: through cables and anchors or using the vessel ́s own propellers. The Dynamic Positioning System smartly maximizes propeller ́s efficiency willing to achieve the desired position and heading. This paper ́s main goal is to present the reader the system ́s structure, it ́s components and how it works, turning data received from Position Reference Systems and Sensors into mechanical answers so the propellers can make the vessel move on a predefined vector. This familiarization should improve the Students results on DP courses.Even being called Dynamic Positioning System, there are many operational modes that make easier not only maneuvering but also navigating, providing safety and precisionto offshore operations. The operational modes were created to serve each specific need the many missions to be accomplished demand.
