Recent Advances in Anchor Design for Floating Structures

摘要

This paper describes advances in offshore anchoring technology made possible through research undertaken recently at the Centre for Offshore Foundation Systems at the University of Western Australia. The paper focuses on the behavior and performance of statically and dynamically installed anchors for floating structures, addressing issues associated with anchor installation and anchor capacity under monotonic, sustained, and cyclic loading. The role of centrifuge modeling, numerical modeling using large deformation analysis, and analytical modeling based on plasticity analysis in advancing anchor technology is presented. This modeling has led to tools that can assist anchor design to reduce uncertainty and optimize performance.
