Abstract: Reliability methods have been applied successfully to two primary categories of uncertainties encountered in geotechnical engineering: Natural variabilities and modeling uncertainties. There are several additional categories ...

Abstract: In August 1995, the Energy Development Corporation installed a conventional drilling and production platform in South Pass Block 47. Due to its proximity to the delta of the Mississippi River, this platform is exposed to ...

Abstract: This paper addresses human and organization errors (HOE) in the context of quantitative reliability analyses (QRA) that are intended to help improve the quality of offshore structures. A ...

Abstract: The effects of cyclic loadings from storm waves on the axial capacity of piles driven in cohesive soils and supporting offshore platforms is described. An advanced analytical procedure is developed to estimate pile ...

Abstract: A general four-tier reassessment and requalification engineering system is developed. The first-tier approach is the simplest. It is based on a qualitative scoring process. The fourth-tier approach is the most complex. It ...

Abstract: Detailed synoptic and climate analyses were undertaken for summer seasons during which extreme mass balance conditions were recorded on glaciers in the Queen Elizabeth Islands in high Arctic Canada. Three types of mass ...

Abstract: structures (Bea, 1991). The evaluations of the loadings addressed loading effects that resulted from dynamic and nonlinear interactions of the structures. Loading uncertainties were organized and characterized in two categories...

Abstract: This paper summarizes development of a process that provides a link between a qualitative assessment and a quantitative probability analysis that can be used to help evaluate the reliability ...

Abstract: Risk assessment and management based hurricane and earthquake criteria have been developed for design and requalification of Petroleos Mexicano platforms in the Bay of Campeche. Results from recent field tests were used ...

Abstract: This paper describes a reliability based formulation to determine earthquake LRFD parameters for conventional, steel, pile supported, tubular member platforms that is proposed as a basis for earthquake design criteria and ...
