consumption in maritime vessels by about 5%consumption in maritime vessels by about 5%. Energy Efficient Thrust Allocation algorithm for maritime vessels

with energy savings of about 40%. Ensuring less wear and tear of thruster motor; Enhanced Dynamic Performance of the drive, because, the

thrusters operate in the efficient region (at higher load);p g ( g ); Simpler v/f control can be used to control the induction motor;

and No need of additional hardware integration The proposed No need of additional hardware integration. The proposed

approach can be integrated in the existing system by changing theDP software.
