3. INTRODUCTION Azimuth thrusters represent a significant advancement in marine propulsion technology, offering unparalleled maneuverability by rotating 360 degrees around a vertical axis. This innovative design allows vessels to achieve precise control and stability, making them essential for complex maritime operations. 3

4. OBJECTIVES Provide exceptional maneuverability and control for marine vessels. E nable precise navigation and positioning, which is crucial for operations in confined or challenging environments. R educe the need for complex rudder and propeller arrangements, and enhance overall vessel stability. A zimuth thrusters contribute to fuel efficiency 4

5. WORKING Input from the main engine is given to the motor generator. Output of the motor is given to the output shaft by a suitable coupling. The power from the horizontal shaft is then transferred to the vertical shaft through an upper bevel gear. This motion is transmitted to propeller shaft by lower bevel gear which results in the rotation of the propeller. 5

9. TYPES OF AZIMUTH THRUSTER MECHANICAL TRANSMISSION ELECTRICAL TRANSMISSION 9

10. MECHANICAL TRANSMISSION A motor inside the ship and is connected to an outboard propeller unit via bevel gears The motor may be either a directly mechanically connected diesel engine Further classified into L-drive and Z-drive 10

11. L-Drive The motor is placed vertically above the propeller The L-drive consists of a vertical input shaft and a horizontal output shaft Power transmission between motor-axis which is connected to the propeller axis is achieved by using a bevel gear arrangement 11 Fig 4 (L-Drive)

12. Z-Drive Z-drive means that the motor is placed horizontally above the propeller Transmission system consists of three shafts Horizontal input shaft , Vertical intermediate shaft , Horizontal output shaft 12 Fig 5 (Z- Drive)

13. ELECTRICAL TRANSMISSION Electric motor is installed in the pod itself Directly connected to the propeller without gear arrangement The energy used to drive the motor in the pod is produced by machinery inside the vessel 13

14. ADVANTAGES Thrust in every direction No rudder required in an azimuth system The underwater dynamics are improved, Increase maneuverability Steering behavior has been increased. It can be built for pushing or pulling operation, at low or high speeds 14

15. Cont. Electrical efficiency, better use of ship space Lower maintenance costs Ships with azimuth thrusters do not need tugboats to dock ‹#›

16. DISADVANTAGES This is suited for ships that spend most of the time in deep water When it is too expensive to install Specialized pilot training 16

17. APPLICATIONS Marine Vessels Offshore Construction Harbor and Port Operations Specialized Vessels Tugs and Support Vessels ‹#›

18. CONCLUSION Azimuth thrusters provide exceptional maneuverability and control by rotating 360 degrees, enhancing the efficiency and precision of marine and offshore operations. Their advanced technology ensures better navigation and positioning for various vessels, highlighting their essential role in modern maritime industry. 18
