Ribeiro e Silva, S., Fonseca, N. e Guedes Soares, C. (2006), “Performance of a Navy Ship Roll Stabilisation System”, Proceedings of the 9th International Conference on Stability of Ships and Ocean Vehicles (STAB´06), 25-29 Setembro, Rio de Janeiro, Brasil
This paper presents a methodology of assessment of a roll stabilisation system for a naval patrol vessel at a certain ocean area where the ship is intended to operate. The 660 tonnes naval patrol vessels considered in this paper are intended to perform law enforcement, fisheries protection, defence operations, and search and rescue primary missions within the Portuguese Economic Exclusive Zone at a maximum speed of 25 knots. The initial roll stabilisation systems under consideration included bilge keels, passive “U” type tanks, activated fins, and combined systems. Ship operational effectiveness is statistically presented by means of an operability index. The calculation of the operability index, which represents the percentage of time during which the ship is able to accomplish a specific task, depends on the wave climate at the design-point, the dynamic response of the ship’s bare hull to the waves, the dynamic response of the roll stabilisation system, and the criteria adopted.
