Computer Methods Of Structural Analysis Of Offshore Structures

By Prof. Srinivasan Chandrasekaran   |   IIT Madras
The course will give a brief overview of different types of offshore structures that are deployed in sea for exploiting oil, gas and minerals. Detailed analysis methods, as applicable to both 2dimensional and 3-dimensional structures will be discussed. While fundamentals of advanced structural analysis are discussed, detailed mathematical modeling of problem formulation and solution using MATLAB coding will be discussed. Codes for numeric examples will be also provided in the lecture notes. Hands-on experience of using Matlab will also be discussed. Focus is on explanation of fundamental concepts of advanced structural analysis, with special emphasis to its application to offshore structures.

    Prof. Srinivasan Chandrasekaran

    IIT Madras
    Srinivasan Chandarsekaran is currently a Professor in the Dept. of Ocean Engineering, Indian Institute of Technology Madras, India. He has teaching, research and industrial experience of about 23 years during which he has supervised many sponsored research projects and offshore consultancy assignments both in India and abroad. His active areas of research include dynamic analysis and design of offshore platforms, Development of geometric forms of complaint offshore structures for ultra-deep water oil exploration and production, sub-sea engineering, Rehabilitation and retrofitting of offshore platforms, structural health monitoring of ocean structures, seismic analysis and design of structures and risk analyses and reliability studies of offshore and petroleum engineering plants. He has been also a visiting fellow under the invitation of Ministry of Italian University Research to University of Naples Federico II, Italy for a period of two years during which he conducted research on advanced nonlinear modelling and analysis of structures under different environmental loads with experimental verifications. He has about 110 research publications in International journals and refereed conferences organized by professional societies around the world. Four text books authored by him are quite popular amongst graduate students of civil and ocean engineering and recommended as reference material for class room studies and research as well. He also delivered four web-based courses namely: i) Dynamic analysis of ocean structures; ii) Ocean structures and materials; iii) Advanced marine structures; and iv) Health, safety and Management in offshore and petroleum engineering. He is a member of many National and International professional bodies and delivered many invited lectures and key note address in the international conferences, workshops and seminars in India and abroad.
