Project List

Text Box: I am working in Technip at present in the department of Fixed and Floating Systems Engineering at the post of a Graduate Engineer. I am dealing with the analysis of the hydrodynamics and motions of SPARs, FPSOs, submersibles, TLPs and other floating production systems used for offshore oil recovery. I have been recently involved with several SPAR projects where I am performing simulations to determine the global response of floating production systems in the Gulf of Mexico under client-provided environmental conditions and sea-states.

I did my B.Tech final year project under the guidance of Prof. T. Sahoo, Department of Ocean Engineering and Naval Architecture, Indian Institute of Technology, Kharagpur. It involved the problem of analyzing the extent of wave scattering and wave energy dissipation achievable by a flexible and porous breakwater which is meant to offer protection to beaches and coastal areas from the catastrophic effects of long waves like tsunamis.

I have worked as a research assistant for two years in an NSF-funded project on the problem of investigating the role of turbulence, coherent structures, and intermittency for controlling transport in multiphase plumes in the environment. Here I have simultaneously worked on the PIV (Particle Image Velocimetry) and LIF (Laser Induced Fluorescence) experimental imaging methods, which involved imaging of velocity and concentration fields of particles released in water. The motion of these particles or phases (which might be air-bubbles, tracers, oil or liquid carbon dioxide droplets) in water produces what is called a multiphase flow. Till date, the single-phase flow equations (equations of continuum mechanics) have been proven to be well-established, however much work still needs to be done to establish appropriate equations to describe multiphase flow. My research focus was on modeling the two-fluid (2 phases) multiphase flow equations for application to deep sea oil and liquid CO2 plumes and validating the models by comparing against experimental data (obtained by coupled PIV-LIF imaging techniques) in the Hydromechanics Laboratory at TAMU.

I did my M.S thesis under the guidance of Prof. Scott A. Socolofsky, Ocean Engineering Program, Civil Engineering Department, Texas A&M University. I developed an existing algorithm for modeling multiphase plumes in the environment to study environmental engineering problems like the aeration of lakes to improve water quality, destratification of reservoirs and CO2 sequestration in ocean to mitigate global warming. The developed model was calibrated by comparing model results to measured laboratory scale data(using PIV imaging technique) and field scale data (using Accoustic Doppler Current Profiler). I also developed a GUI interface using MATLAB for analyzing the motion and entrainment characteristics of air-bubble and liquid CO2 plumes in water.
