A rudder system that confirmed 14% energy-saving performance in actual ships.
The "Gate Ladder (R)" is a new type of rudder system that positions the rudders on both sides instead of behind the propeller, generating thrust through its specially shaped rudders, achieving a 14% energy-saving performance in actual ship measurements. In the unlikely event that one side's rudder fails, the ship can still turn, ensuring redundancy. The "Clubbing Mode," which allows lateral movement of the ship, contributes to improved safety in port areas. 【Performance】 ■ Energy-saving performance ■ Excellent course-keeping and turning performance ■ High quietness performance *For more details, please download the PDF or contact us.
