International marine-pollution regulations which become law on 2 Oct. 1983 will set precise oil-content limits for bilge and ballast discharge from tankers and other ships. After giving the gist of these regulations and of IMO Resolutions relating to equipment for meeting them, the article gives some general information on the various methods of oily-water separation and monitoring that are available. Brief descriptions are included of the Babcock Bristol OTM17X computer-based tanker-deballasting monitor and the Sarex gravity-type separator. The Oil Companies' International Marine Forum <OCIMF> has informed the Marine Environment Protection Committee <MEPC> of serious short-comings that tanker operators have experienced with ballast oil-content monitoring equipment, and OCIMF has proposed deferment of installing monitoring equipment for three years, after which the operational viability of the equipment would be reviewed. This proposal, which is not favoured by some countries <including the UK>, is briefly discussed in the article, together with some measures for resolving the difficulty. It is also mentioned that there have been problems with the separators themselves. A list of IMO-recommended suppliers of separation and monitoring equipment is appended to the article.
