Offshore structures under special loads including Fire resistance

ABOUT THE COURSE:

This course deals with novelty of offshore structures and their response behaviour under special loads. These loads include earthquake loads, ice loads, shock and impact loads, ringing and springing wave loads and loads caused by crticial sea states. The course also deals with advanced structural analyses methods including unsymmetric bending and estimate of shear centre. It also deals with analysis of curved beams, crane hooks, chain links and rings and marine risers under Vortex induced motion. Fire in one of the major hazard in offshore industry. Fire-resistant design is a mandatory requirement for members exposed to high fire hazards. This course will expose participants to fundamentals and explain the fire-resistant design concepts through a variety of examples. A full black-board teaching model, with illustrated examples and tutorials is followed with 24x7 active discussion forum to clarify doubts.

COURSE LAYOUT:

1. Introduction
            This section of the course will deal with novelty of various offshore structures commissioned for oil and gas exploration, production, processing and storage etc. Response characteristics with respect to their novel geometric form will be discussed in detail. Third generation platforms, with recent updates in the research front will be highlighted. This module also presents details about the conventional environmental loads acting on offshore platforms along with the governing equations to estimate these forces. It explains in detail special loads namely: seismic loads, ice loads, shock and impact loads that act on offshore platforms; their estimates and methods of analyses are dealt in detail.  In addition, special events that arise due to formation of distinctly high sea waves, springing and ringing waves and their application to offshore compliant platforms with geometric optimization is also presented.

2. Advanced structural analyses
            This section explains the necessity of advanced analyses tools to deal with offshore platforms under special loads. Detailed analytical model and derivation of governing equations of member under unsymmetric bending, curved beams etc are presented. Numeric examples on the above with shear center estimates are discussed to enhance learning skills of the viewer. In addition, it also deals with application of the advanced topics to chain links, closed rings, marine risers etc. Application studies, dealing with suppression systems of Vortex induced vibration is one example of novel application dealt in this module. 

3. Fire resistance
            In this module, objective of fire resistance, including characteristics of fire are discussed. Theory on fire damage and control, types of fire in offshore platforms, fire-resistance tests, fire ratings, behavior of structural members under fire are presented. Examples are chosen to explain the concept in a more simplified manner.

Further, it also contains tutorials, model question paper and key to them for enhancing self-learning

ABOUT THE INSTRUCTOR:

Srinivasan Chandrasekaran 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 & 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.
