各位船友大家好，目前国内减摇鳍设计相关的通用规范就一个GJB2860-1997，有谁知道国外的减摇鳍设计通用规范或者标准名字吗？如果有的话，请告知下标准代号及名称，非常感谢！！！

Ship stabilizers
Ship stabilizers (or stabilisers) are fins or rotors mounted beneath the waterline and emerging laterally from the hull to reduce a ship's roll due to wind or waves. Active fins are co***olled by a gyroscope co***ol system. When the gyroscope senses the ship roll, it changes the fins' angle of attack to exert force to counteract the roll. Fixed fins and bilge keels do not move; they reduce roll by hydrodynamic drag exerted when the ship rolls. Stabilizers are mostly used on ocean-going ships.

Active-fin stabilisers
MARINE
The reduction of rolling provides better fuel/speed performance on rough seas, enhances crew safety and possibly their efficiency. The roll amplitude can be reduced by passive devices, such as bilge keels, or by active devices, such as hydrofoilshaped fins usually located near amidships, port side and starboard. In a seaway, hydraulic tilting gear continuously varies the angle of attack of the fins, to produce heeling moments reducing the ship tendency to roll. Active-fin stabilisers require ship forward motion in order to develop lift. They are available as folding types or non-retractable construction. For many years active-fin stabilisers have been applied on cruise ships and passenger vessels as a means of reducing excessive rolling. Today, owners of other types of vessels, especially large containerships, are increasingly specifying fin stabilisers.

我第一次看到這類船舶防搖鰭是60年代中期在廣州檢驗我國遠洋客船 “ 耀華 ” 時。該輪是從法國定造引進的。錢船長告訴我，為了瞭解掌握該船防搖鰭實際技術性能，他在風平浪靜的海面，全速前進（20 節？），然後開動防搖鰭的控制系統，人爲調控左右鰭的正負攻角，令船橫搖起來。結果測得，達到橫搖 21 度。從而得知該輪大概的抗橫搖能力。
