The paper describes the results of analytical investigation on the application of vane-turbine in the propeller slipstream. The vane-turbine is attached on single-and twin-screw ships with total number of investigated ships are 20. Performance of the turbine was analyzed by actuator disc method. The effect of vane-turbine on ship performance is investigated. Discussions are focused on two main topics, namely speed loss and power efficiency gain. Final result finds out that the ratio of the thrust-power producing by vane turbine and thrust-power producing by propeller will influence the efficiency gain.

“…At the actual speed, the power of the vane turbine recovers the power loss of the engine. Thus, the efficiency gain (EG) is defined as , All the calculation concerning with the effect of vane turbine are presented in [10], [11]. Most of single screw ship, applying this system is beneficial.…”
