The Offshore Site Investigation and Geotechnics Committee (OSIG) is honored to present "Geomechanics of Marine Anchors" by Dr. Charles Aubeny, Associate Professor from the Civil Engineering Department at Texas A&M University and member of SUT-US.

This presentation is based on Dr. Aubeny's book published last fall, following the outline below. A networking event will follow at Tango & Malbec after the presentation (registration cost includes entrance to the networking event).

Presentation Outline
I. Overview of Anchors
   a. Anchor system alternatives - at least 7 choices in basic systems
   b. How they work - understanding basic mechanisms of resistance
   c. Relevance of loading conditions - duration, cycling, orientation
   d. Measures of performance - pros/cons of the various options
V. Ultimate Capacity of Piles & Caissons
   a. Upper bound analysis - practical estimates of capacity & optimal load attachment depth
   b. Combined loading - estimating capacity  for H-M and V-H-M loading
   c. Practical issues - torsion, tolerances 
II. Significance of Seabed Soil Conditions
   a. Must-know considerations for clays - undrained strength, consolidation…
   b. Must-know considerations for sands - frictional & dilative behavior
VI. Elastic effects
   a. P-y curves - traditional curves plus recent developments
   b. Soil-pile interaction - classical analysis of long, slender piles
   c. Ovalization - potential reductions in effective capacity of short piles/caissons
III. Analytics and Benchmark Solutions
   a. Analytical methods - survey of widely used methods
   b. Uniaxial solutions - useful closed-form solutions
   c. Interaction diagrams - dealing with combined loading conditions
VII. Drag Embedded Anchors
   a. Basic mechanics - analysis from fundamental solutions
   b. Design tools - practical predictive methods
IV. Caissons/Pile Installation
   a. Suction - penetration mechanisms in clays and sands
   b. Gravity - recent numerical, analytical & experimental predictive methods
   c. Driving - most versatile but relatively high-cost approach
VIII. Direct Embedment Plate Anchors
   a. Installation - suction, gravity, driving, torsion
   b. Keying - methods for predicting embedment loss
   c. Capacity - pullout capacity in clays & sands


About the Presenter

Dr. Charles Aubeny is a Professor of civil engineering at Texas A&M University, specializing in geotechnical engineering. He is a licensed professional engineer in Texas, California and Colorado. He received a BS degree at the University of Arizona, an MS degree at the University of Colorado in Denver and a doctoral degree in civil engineering at the Massachusetts Institute of Technology. Dr. Aubeny has held his current faculty position at Texas A&M University since 1999. His research and professional interests include deep-water anchors, subsea risers and conductors, subsea gravity foundations, embankments, slope stability, excavations and retaining structures. He teaches courses in geotechnical engineering, foundation engineering, slope stability and retaining walls, and numerical methods. He consults on wide variety of projects, including projects in deep-water Gulf of Mexico and offshore Australia. He received the Thomas A. Middlebrooks Award in 2002 and is a Fellow of the American Society of Civil Engineers.
