The design and analysis of offshore structures is associated with a unique set of challenges that require knowledge of various engineering disciplines. The goal of this project is to develop an integrated numerical modelling framework that can yield optimal mooring and anchor structure designs capable of withstanding the constrained environment and field conditions in both low and high energy areas. The integrated framework will couple state of the art geotechnical and mechanical numerical modelling approaches to study the behaviour of cage-mooring-anchor interactions. The framework can then be used to design and optimise offshore aquaculture structures, taking into account different design variables.
