Reliability of API and ISO Guidelines for Bearing Capacity of Offshore Shallow Foundations

The safe bearing capacity for offshore shallow foundations has been traditionally assessed using working stress design (WSD) methods (e.g. the API RP 2GEO guideline). Other codes of practice such as the ISO standard strive to provide designs achieving a desired target reliability level in the form of the Load and Resistance Factor Design (LRFD)...

Risk Analysis of Earthquake-Induced Submarine Slope Failure

This paper presents an offshore risk analysis in a systematic manner to assess the influence of earthquake-induced submarine slope failure on offshore structures. The risk analysis is carried out for the future development of a natural gas field in deep waters in the south part of the Gulf of Mexico. The study accounts for all the elements in...

Accounting for Uncertainty and Variability in Geotechnical Characterization of Offshore Sites

This paper presents an overview on how uncertainty and variability of mechanical soil properties are dealt with in offshore site investigation and presents some ideas for utilizing the reliability tools in a more optimal manner for this purpose. Two types of problems are addressed. First, how to extract the maximum amount of information from...
