Biography
Bert Sweetman, PE, Ph.D., is an Assistant
Professor in the Department of Maritime Systems Engineering in Galveston,
and is an Assistant Professor in Civil Structural Engineering in College
Station. He joined TAMUG in January 2003. He holds a Ph.D. from Stanford
University in Civil Structural Engineering, a Master of Engineering from
Texas A&M in Ocean Engineering and a Bachelor of Science in Engineering
from the University of Michigan in Naval Architecture and Marine
Engineering. Professor Sweetman is a licensed Professional Engineer in
Texas, with ten years of engineering experience in Mobil Oil’s central
engineering division. His industry experience ranges from long-term
research to management of design and construction projects.
Industrial research initiatives included
development and evaluation of novel floating production concepts
(including spars, FPSO’s and TLP’s), station-keeping methodologies, and
development of software tools for engineering applications. Project
management responsibilities included schedule and cost estimating for very
large offshore projects and included direct responsibility for
construction of an office building and for construction of the marine
parts of a floating production and storage vessel. He holds patents on
fairings for marine risers, a novel floating barge-platform and its method
of assembly, and served on the American Petroleum Institute’s committee to
develop the API guidelines for floating production.
Professor Sweetman's current research is on
development of new methods to apply random vibration theory to better
understand vortex induced vibration of marine risers and to develop new
structural health monitoring methodologies. He also applies advanced
statistical methods to better understand irregular environmental loading
on wind turbine support structures. Generally, his interests lie in the
areas of random processes and in statistical prediction of extreme values
in non-linear dynamic systems subject to these random processes. He has
published numerous journal and conference papers in the areas of air-gap
analysis of floating structures, wave-structure interaction, and
second-order random wave propagation. He presently overseas maintenance
and development of the software tools originally produced within the (now
defunct) offshore part of the Reliability of Marine Structures research
group at Stanford University.
Professor Sweetman’s teaching interests
include engineering statics and particle dynamics, in which the ENGR-221
class recently completed a competition to test towers made of uncooked
spaghetti and epoxy (See photos of competition here). Additional teaching
interests include engineering statistics, structural steel design and the
Senior capstone design course in offshore structures. Professor Sweetman
holds joint appointments with Texas A&M at College Station in Civil
Engineering and in Ocean Engineering. His research is presently funded by
two grants from the National Science Foundation division of Civil and
Mechanical Systems: Sensors: Statistical Algorithm Development for
Distributed Sensor Networks with Application to Structural Health
Monitoring and State Assessment (2004 - 2007), and CAREER: Irregular
Environmental Loading and Response of Offshore Structures. (2005 - 2010).
He presently supervises Doctoral candidate, M. K. Choi, who is developing
advanced statistical methods with application to vortex induced vibrations
of marine drilling risers and Doctoral student Mahdi Karimi, who is
developing a numerical model for floating offshore wind turbines. He is
also a committee member for one Master's student in Aerospace Engineering.
