Product: Super Stream Duct (SSD) Energy Saving Devices

Benefits

① By straightening the stern flow, it reduces hull resistance and also generates its own forward thrust.
② The thrust reduction coefficient (t) decreases due to its own thrust.
③ The wake coefficient (ω) increases due to its own presence and the induced speed to the propeller.
For the above reasons, SSDs are more effective when used on blunt ships equipped with high-load propellers.
・The effect varies depending on the propeller load and the bluntness of the ship, but energy savings of 3 to 8% can be expected.
