Marine Propulsion

By Prof. Anirban Bhattacharyya   |   IIT Kharagpur
Learners enrolled: 541
ABOUT THE COURSE:
The course covers different aspects of marine propellers and propulsion starting with the basic concepts of screw propeller geometry, theories of propeller action, hydrodynamics in open water and behind-hull conditions and practical calculations of ship powering from model test results. Other topics include propeller cavitation, blade strength, and engine-propeller matching. Some propeller design methods and concepts will be discussed. To give a general overview of the propulsors used in marine vessels, controllable-pitch propellers, ducted propellers, podded propellers, and unconventional propulsion devices like waterjets, oscillating propulsors etc. will be included along with thrust augmentation devices for improving energy efficiency. The course should provide a general understanding of marine propulsion for both graduate students and professionals working in the maritime industry.

INTENDED AUDIENCE: Students pursuing B-Tech/ M-Tech degrees in Naval Architecture, research scholars, and working professionals in the maritime industry.

PREREQUISITES: Knowledge of Hydrodynamics, Basic Ship Theory and Ship Resistance.

INDUSTRY SUPPORT: Shipbuilding industry, Naval Architecture firms

Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
