Operação de posicionamento dinâmico nível 2

Abstract

Since the development of satellite navigation is possible to retain drilling rigs and ships in position dynamically using their own propulsion systems. Units toward propeller-driven by electric motors are often the most used. This paper presents the development of a dynamic positioning system to suplly vessels platforms DP class 2 techniques were investigated, regulatory standards, training and defining the responsibilities of professionals involved in the operations. Specifically for this work will be used as a vessel model. Supplier of PSV 4500 platform design with electric / diesel propulsion azimuth 7600 BHP widely used in the offshore marine support. The vessel will be classed with LRS notation DP AA, equivalent to class 2 DP IMO. According to the IMO, for DP equipment class 2, a loss of position should not occur as a result of a natural fault in any active component or system. The single failure criterion includes: any active component or system (generators, thrusters, switchboards, remote controlled valves, etc.); any normally static component (cabling, pipes, manual valves, etc.) that do not submit properly documented for the protection and reliability. The IMO also shows that an inadvertent singular act should also be considered as a singular failure, if it is probable. For notation DP AA, the LRS requires that systems of power, control and thrusters, as well as other needed to, or that may affect the proper operation of the DP system systems should be provided and configured such that a failure in any active component or system does not result in a loss position.
