Study of the formation of unpumpable residues of crude oil on tankers for the purpose of preventing marine pollution
This paper summarizes a study of the formation of unpumpable crude oil residues in tankers. Aimed at preventing marine pollution, the original dissertation was published in the USSR in 1974. A conclusion is made in the study on the expediency and feasibility of accurately estimating the volume of washed up and accumulated oil residues after each unloading and washing of tanks depending on specific operating conditions of any tanker. New regulations of the International Convention for the Prevention of Pollution from Ships, 1973, regarding inspections for detecting sources of marine pollution by oil require a universal criterion for an objective estimation of the quantity of declared residues in slop tanks which are to be disposed of by tankers. The research in question is aimed at substantiating such a criterion and developing recommendations on its practical application. The research method involved a broad experiment to study the adhesiveness of various crude oils to actual models simulating inner tank surfaces. Considerations were made for the design characteristics of various tankers, the spatial orientation of wet surfaces, and actual parameters of their typical corroded condition. The research undertaken makes it possible to consider a specific model of a cargo tank of any tanker taking into account not only the location of wet surfaces and their dimensions, but also their physical condition. In conclusion, by means of mathematical treatment of data obtained in the study, methods are recommended for estimating the anticipated volumes of crude oil residues in tankers relative to specific operating conditions. The study also contains information concerning the possible optimization of modes of using tank washing equipment and the reduction of ship energy expenditure for tank washing.
