Ongoing Projects:

NTPC Floating Power Plants - Ramagundam and Kayamkulam (December 2020)

Currently, our group is providing consultancy services to Adtech Systems Limited - an Engineering, Procurement and Construction (EPC) firm involved in the development of floating solar power plants for NTPC (National Thermal Power Corporation). This project involves the development of large floating blocks to harness solar power from the water reservoirs of NTPC. We are currently performing third party validations for the design of two modules within these floating blocks - one at Ramagundam and the other at Kayamkulam.

Past Projects:

Det Norske Veritas (DNV), Houston, TX, USA (2016)

During discussions with DNV, an idea was proposed to calculate nonlinear pressures around the hull and map them to a mooring program to enable true dynamic coupling between hydrodynamic program SIMDYN and the mooring program OrcaFlex. Although this discussion did not materialize into a project, the research work to enable mapping of pressure from SIMDYN to other programs was completed. The proposal presentation can be accessed here.

American Bureau of Shipping (ABS), Houston, TX, USA (2014)

As a part of this project at ABS, I evaluated the theoretical accuracy and limitations of a design wave generation tool called PROFILES. This program generates short wave elevation time series that would in theory result in an extreme bending moment or shear force response corresponding to a user specified wave spectrum and probability of exceedance. The idea is that a 100 second wave profile from PROFILES can generate the extreme response corresponding to a specified probability of exceedance without the need to simulate multiple time histories. I studied and documented the theory behind the program and also performed extensive validation studies comparing PROFILES with the ABS in-house nonlinear time domain simulation tool. As a part of this investigation, the limitations of the program were shared with the Technology Research group of ABS.

Floatec LLC, Houston, TX, USA (2013)

The objective of this project was to help Floatec improve the efficiency of their coupled motion analysis tool. Their coupled motion analysis consisted of two stages - a frequency domain analysis using in-house code HYDRO3 whose results (added mass, radiation damping, first and second order forcing) were utilized by the time domain tool ABASIM (combination of ABAQUS and MULTISIM) to simulate the nonlinear coupled motion of a platform/vessel. As the existing frequency domain hydrodynamic engine HYDRO3 was relatively slower than the commercial counterpart WAMIT, I was delegated the task of integrating WAMIT with ABASIM. Due to the significant differences in coordinate system orientations and conventions between WAMIT and ABASIM, I investigated the conventions of both softwares to come up with a transformation to convert WAMIT results into the ABASIM convention. Later I coded this transformation into a FORTRAN code to enable a easy transition between the two programs. The code was extensively validated by comparing the results of simulations of 100 year storm scenarios for both TLP and spar platforms between the older and the newer approaches.
