OSIG - Offshore Site Investigation and Geotechnics Committee
Offshore Site Investigation and Geotechnics
Aim and Technical Remit:
To provide a recognised forum concerning offshore site investigation, foundation behaviour and associated areas of geophysics, geology, geotechnics and the offshore environment. The purpose of the committee, as defined in the constitution, is:
- To promote best practice for issues within the OSIG Committee s remit within the offshore industry
- To be a recognized learned body providing advice on issues within the technical remit of the Committee to other non-commercial organizations
- To organize and provide education and training courses, international conferences and workshops / seminars to the offshore industry to foster best practice and knowledge transfer and dissemination.

Current OSIG Chair
Zenon Medina - Cetina, PhD
Texas A&M University
Assistant Professor, Stochastic Geomechanics Labratory
Dr. Medina-Cetina is Assistant Professor at the Texas A&M University, where he leads the Stochastic Geomechanics Laboratory SGL (2008 - Present). He is a Civil Engineer from the Universidad Autonoma de Yucatan UADY Mexico (Highest Honors, Soil Dynamics, 1994), and a Master of Engineering from the Universidad Nacional Autonoma de Mexico UNAM (Geostatistics, 1996). While at the UNAM, he obtained a faculty adjunct position in the College of Engineering, and worked as a research assistant for the Instituto de Ingenieria I de I (1996 - 2001). During this same period of time, he worked as independent consultant and Project Manager of the Geostatistical Site Characterization of the Rion-Antirion Bridge in Greece (1998-2001). Dr. Medina-Cetina obtained a Masters of Science and a Philosophy Doctorate at The Johns Hopkins University (Stochastic Mechanics, 2001- 2006). He held a dual appointment at the Norwegian Geotechnical Institute NGI in Oslo Norway (2006 - 2008), in the International Centre for Geohazards ICG and in the Computational Geomechanics Division CGD. His research and consulting interests in Offshore Site Investigation and Geotechnics include Risk, Reliability and Sensibility Analysis; Probabilistic Site Characterization for Integrated Studies (Geology, Geophysics and Geotechnical); and Uncertainty Quantification of Multi-Physics Geomechanical Processes. He is a member of the Society of Underwater Technology; of the American Society of Civil Engineers ASCE s Geo-Institute (Risk Assessment and Management Committee), Engineering Mechanics Institute EMI (Computational Mechanics Committee), Coasts, Oceans, Ports and Rivers Institute COPRI (Marine Renewable Energy Committee, Risk and Reliability Working Group); of the Society of Industrial and Applied Mathematics SIAM; and of the American Statistical Association ASA.
Earl H. Doyle received his B.S.C.E. and M.S. Ocean Engineering degrees from the University of Rhode Island and retired from Shell Oil Company in Houston after more than 30 years of employment. At Shell he was responsible for the company's deepwater geotechnical and foundation design activities. This included the integration of high-resolution geophysical data to a geological model from which development assessments were made. During his first 17 years, he was involved in geotechnical engineering research at Shell Development Company. While there, he was responsible for the development of the Remote Vane and the EDO deep tow system and its extensive use on the U.S. East Coast and Gulf of Mexico. For his last 13 years, Doyle led the geohazard, geotechnical and foundation design efforts for several important structures, including the Xijiang structures offshore China, several shallow water Gulf of Mexico platforms and the Auger, Mars, Ram/Powell and Ursa Tension Leg Platforms (TLPs). He has authored or co-authored more than 40 publications in the geotechnical and geoscience field. Doyle presently is a consultant in the area of geotechnical engineering and integrated geoscience studies and specializes in the design of pile foundations for TLPs where he has designed pile foundations for more than half of the world's installed TLPs.
Past OSIG Chair
R. Craig Shipp, Ph.D., P.G.
Shell International Exploration and Production Inc.
Geohazards Advisor, Geohazards Assessment and Pore Pressure Prediction Team
Craig Shipp earned a M.S. in Geology at the University of South Carolina and a Ph.D. in Geological Oceanography from the University of Maine. He was hired as a research geologist by Shell Development Co. 1988. An early job assignment was a deepwater near-surface analog study for the deeper interval that evolved into the initial focus on deepwater drilling hazards. In 1997, he became a geohazards specialist on the multidisciplinary Shallow Water Flow Team, focusing on drilling hazard assessments in the deepwater Gulf of Mexico. Since Shell E&P globalization in 1999, Craig has concentrated on the development of the current evaluation group at Shell that specializes in the global assessment of offshore geohazards for drilling and field developments. In related activities external to Shell, Craig has served as the AAPG Chairman for the Offshore Technology Conference Technical Program Committee (2004-2009), founder and convener of the Operators Geohazards Forum (2003-2009), a member of the Expert Panel on Gas Hydrates for the Canadian Council of Academies (2007-2008), and co-chairman of the 4th International Symposium on Submarine Mass Movement and Their Consequences (2009). Also, he was selected as an AAPG Distinguished Lecturer on geohazards and submarine mass movement for the Asia-Pacific Region (2006-2007). Presently, he serves on Environmental Protection and Safety Panel for the Integrated Ocean Drilling Program (2002-present) and U.S. Dept. of Energy Methane Hydrates Advisory Committee (2008-present). His current interests are deepwater depositional systems, geotechnical character of deposits formed by deepwater processes, and effect of mass-failed sediments and marine gas hydrates on deepwater drilling and development operations. Craig assumed chairmanship of the Houston OSIG Committee in January 2010.
