Recent Advances in Anchor Design for Floating Structures

摘要

This keynote paper describes advances in offshore anchoring technology, made possible through research undertaken over the last five years at the Centre for Offshore Foundation Systems at the University of Western Australia. The paper focuses on the behaviour and performance of statically and dynamically installed anchors for floating oil and gas facilities and floating renewable energy facilities, addressing issues associated with anchor installation and anchor capacity under monotonic, sustained and cyclic loading. The role of physical modelling techniques using centrifuge technology, numerical modelling using large deformation analysis and analytical modelling based on plasticity analysis in advancing anchor technology are presented. This modelling has led to tools that can assist anchor design to reduce uncertainty and optimise performance.
