Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>Corrosion modelling of decay rates of the iron wrecks in Port Phillip Bay, Victoria, has enabled an estimation of the speed at which the historic resource of iron shipwrecks is disappearing. Use of the significance ranking of the iron wrecks, based on the Australian National Standards for significance assessment, provides a useful guide to decision-making, but decisions based solely on these criteria can lead to less than optimal results. From the corrosion rates and the amount of residual metal thickness in structural elements it is possible to determine a conservation ranking that is based on the need for intervention and the chances of being successful in stabilizing the wrecks. The arithmetic product of the significance and conservation rankings defines the treatment score or ranking which forms the basis for rational decision making about deployment of resources.</p> </abstract>
