Summary

 
Object and purpose of research. This paper studies multi-purpose two-staged blade propulsor with counterpropeller in order to improve control and power efficiency of ship
Subject matter and methods.The study is based on model test data and calculation results
Main results. Taking a large fishing vessel as a case study, this paper demonstrates the efficiency of dual-action counterpropeller as active ship control tool and compares it versus conventional tunnel thruster.
Conclusion. A ship equipped with the system suggested in this paper may receive an additional symbol to its RS class notation: redundancy of propulsion system elements
