Abstract | Aid-to-navigation (A-to-N) structures are predominantly made of steel, which is susceptible to corrosion in an aggressive marine environment. Replacing steel with GFRP composites will eliminate the expensive maintenance activities of the A-to-N infrastructure currently costing an average of $3.7 million per year in Queensland alone. In the present paper, key findings of an extensive finite element investigation along with analytical solutions for evaluating the structural responses of the GFRP composite A-to-N structures subjected to hydrodynamic sea wave forces, marine current loads, wind forces, and vessel berthing/collision impacts are presented and discussed. After the evaluation of structural performance for the serviceability and ultimate limit states in various water depths and seabed conditions, findings of the life-cycle cost analysis (LCCA) and life-cycle environmental impact assessment (LCEIA) of composite A-to-N infrastructure are presented to systematically compare the proposed fibre-composite A-to-N system with the traditional steel structure from the life-cycle cost and environmental impact points of view. Results indicate that the GFRP composite A-to-N structure can be considered as a cost effective and sustainable alternative for the conventional steel A-to-N system. |
