Numerical Ship and Offshore Hydrodynamics

By Prof. Ranadev Datta   |   IIT Kharagpur
Learners enrolled: 198
ABOUT THE COURSE:
This course will provide the thorough understanding of the several numerical methods in the domain of ocean engineering, broadly in the domain of wave structure interaction. The proposed course mostly focuses on different numerical methods based on potential theory, for example, zero and forward speed 3D frequency and time domain panel method, strip theory, time domain method based on Impulse response function etc. Also, at latter stage of the course, Hydroelasticity of ship will also be discussed. This is a comprehensive and contemporary course for industry personnel, undergraduate, masters and PhD level students in the domain of ocean engineering/ mathematics/civil engineering.
 
INTENDED AUDIENCE: BE/ME/Ph,d Student in the field of Ocean Engineering and Naval Architecture, Mechanical Engineering, Civil Engineering, Industry personnel from Ship and Offshore Industry, Classification societies etc.

Instructor bio

Prof. Ranadev Datta

IIT Kharagpur
Dr. Ranadev Datta is now an Associate Professor in the department of Ocean Engineering of Naval Architecture, Indian Institute of technology Kharagpur, India. He did his PhD in the same department in Numerical Ship and Offshore Hydrodynamics. He worked in IST Lisbon, during 2009 to 2012. The primary research interest of Dr. Ranadev Datta is related to ship and offshore structure seakeeping, Hydroelasticity. He had developed a higher order 3D time domain panel method to solve ship motion problems during his graduation. Presently, his research area includes hydroelasticity, nonlinear fluid structure interaction problem, computational geometry etc. He is now involved in a project supported by the Naval Research Board where they are trying to solve hydroelasticity problem by coupling the boundary element method (BEM) and finite element method (FEM) in time domain. Also working on the nonlinear wave- structure interaction problem, the focus is to find an efficient way to couple the classical potential flow method with popular CFD solvers, so that the local phenomenon such as deck wetness/ slamming can be modelled using CFD. Dr.  Datta has worked on several industry-related projects. He has helped IRS (International register for shipping) to develop their classification rule book. He also developed stability software for jack up Rigs with Green Palm Marine Consultancy. Apart from that, he has been involved in many small scale routine consultancy projects as well. Apart from his work related to numerical ship and offshore structure hydrodynamics, he is also keen in developing an automated meshing engine for ship like structures using the key concept of computational geometry.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 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.
