Abstract

Ships’ ranging at berths has caused lost production and safety hazards in several ports around Australia and New Zealand. Ranging is caused by the interaction of infragravity (IG) waves with ships on their moorings having resonant natural frequencies of oscillation. This can be exacerbated in harbour basins having resonant length scales. In this paper we focus on the processes of IG wave generation, the relevance and importance of incorporating a wide field domain in the numerical IG models of harbour resonance, the importance of IG wave directional spectra and the possibilities of manipulating harbours to avoid seiching. We do not address mooring line arrangements for managing IG wave issues.
