Offshore Site Investigation and Geotechnics (OSIG)


Design and Reliability of Offshore Geo-Structures
One-Day Short Course
Monday, August 21, 2017 8:00am-5:00pm


Risk management is an important skill needed throughout all aspects of geotechnical engineering. Most decisions need to be made without knowing for certain how the decision will play out, introducing risk and making it difficult to communicate those decisions to stakeholders such as owners, regulatory agencies and the public. This course will provide practical tools to make, analyze and communicate risk-based decisions. It will incorporate case histories and audience participation.

Course Topics

Design of Shallow Foundations
LRFD with Emphasis in Offshore Geo-Structures
Decision Analysis
Random Variables
Reliability-Based Design
Value of Information Analysis
Risk Communication.

Integrated Site Marine Characterization Course

A marine site investigation integrates geology, geophysics, and geotechnical data to develop the soil properties required to understand geological constraints and to gather information to design submarine foundations and layouts. Who should attend? Geoscientists, engineers, and managers who work, contract, and plan marine site survey and geotechnical programs for exploration and field development.
The three-day comprehensive course covers survey planning, acquisition, interpretation, and integration of data, culminating with an in-depth presentation of several integrated case studies. The course is taught by recognized experts in these fields from energy company operators, service contractors, consultants, and academic institutions.
