Controlling means for ship stabilizing gear

Abstract

To provide a control method for a rocking reducing device in which a buoyancy type rocking reducing device (fin stabilizer or rudder swing reducing device) of automatic control type and a U-pipe passive type swing-reducing water tank device (ART) of automatic control type are installed in line and used, capable of allowing the two devices to work with their merits efficiently, complementing each other's demerits, and performing an automatic control so that the liquid of ART does not ill influence the F / S (fin stabilizer). The buoyancy type rocking reducing device 14 of automatic control type and a passive type swing-reducing water tank 15 of automatic control type are installed in line, and a control part 4 capable of making remote control of the two devices is installed on a bridge or in an apparatus monitoring room. A system is constructed so that the two devices 14 and 15 can be selected through changing-over by an automatic or a manual operation. In the case of automatic selection, priority for use is given to the device meeting the preset conditions on the basis of the vessel information fundamentally, and the automatic control is conducted in such a manner that the other device does not ill influence the selected device.

Description

Technical field [0001] The present invention relates to a fin stabilizer, and a control method when a lift-type and passive-type anti-roll tank (limited to U-shaped tube type) is installed and used at the same time, such as a fin stabilizer or a rudder stabilizer device, especially automatic selection The above-mentioned anti-rolling device, which is most suitable for the ship's speed or other conditions during sailing, and a method of controlling the anti-rolling device of a ship. Background technique [0002] In the past, fin stabilizers (hereinafter also referred to as F / S) or rudder anti-rolling devices were actually used to use the FIN (wing plate) protruding out of the hull or the lift generated on the rudder surface as the anti-rolling moment. Lift type and U-tube type passive anti-rolling tanks (hereinafter also referred to as ART) that use the natural law of liquid flowing from high to low are used as ship's anti-rolling devices. The device can obtain sufficient anti-rol...

Problems solved by technology

[0020] However, most of the existing technologies do not have long-distance driving equipment. At this time, the crew operates manually. Therefore, the F / S with high anti-rolling efficiency is the main method, and ART is used as the low speed state of the ship. Or auxiliary usage when the ship is stopped, but due to the fact that the companies that manufacture and sell F / S and ART are different, the actual operation is very troublesome, so no example of connecting the controls of the two devices together has been found.
