3 Mechanism of GATE RUDDER\u00ae for achieving energy saving<\/strong><\/h2>\n\n\n\n

Rudder placed in parallel both sides of the propeller reduce not only the resistance by the rudder, but also cavitation and toe angle of offset rudder (counter-steering) and these advanced mechanism affects multiply during the operation of the vessel to achieve fuel (energy) saving.<\/p>\n\n\n\n

\u2776 Reduce resistance of rudder<\/h3>\n\n\n\n

Instead of placing behind the propeller, which is conventional construction, by placing two unsymmetrical rudder blades in parallel both sides of the propeller, reduce resistance of rudder and by the rudder blades create thrust to reduce hull resistance on self-propulsion condition.<\/p>\n\n\n

\u2777 Suppress cavitation<\/h3>\n\n\n\n

Since GATE RUDDER\u00ae SYSTEM could create thrust, necessary thrust of propeller (to make same ship\u2019s speed) could be reduced and cavitation could also be reduced, Further more by rectifying the stream facing to the propeller, the occurrence of cavitation is suppressed. Furthermore, since speed of the stream facing to the propeller is also rectified, torque nonuniformity is reduced to improve fuel consumption of main engine.<\/p>\n\n\n\n

During the operation in the ocean, it has turned out that there is a certain tendency for bow of vessel with GATE RUDDER\u00ae not to sway from side to side, which reduce the counter steering and contribute save energy operation of the vessel.<\/p>\n<\/div>\n\n\n\n
