Abstract
Australia has an increasing number of offshore facilities for oil and gas production and gathering; all will eventually reach the end of their economic lives. Facilities include concrete or steel structures, weighing up to several tens of thousands of tons and in water depths of over 100m, several smaller structures, and hundreds of kilometres of pipelines on the sea floor. Abandonment, without adequate provision and responsibility for maintenance of navigational hazard warnings, and without offloading residual toxic wastes, is not an acceptable option to shipping, fishermen, or the community. Removal, whether partial or total, requires considerable expenditure that companies would clearly prefer to minimise; dumping offsite has environmental and other implications. This paper describes and discusses the types of facility presently installed, current legislative requirements in Australia, the question of the timing of cessation of production, and the economic and environmental implications of various options that have been proposed.
