In 1973 the International Conference on Marine Pollution drafted rules to limit the intentional pollution of the sea by ships, mainly tankers. These rules will come into force one year after 15 countries, together representing at least 50% of world tonnage, have signed the International Convention for the Prevention of Pollution from Ships (briefly referred to as MARPOL 73). First of all, however, practical solutions for the operation and equipment of ships to comply with the regulations must be found and laid down in IMCO standards. In the Netherlands an extensive research programme has been carried out by Koninklijke/Shell Laboratorium, Amsterdam, sponsored by the Netherlands Maritime Institute. The main questions to be solved were: How can the amount of residue left in a tank be determined in a simple way? How should tanks be washed? How can slops be discharged to the sea in a controlled way? Results of the research work had to be available within a short time, in a practically acceptable form; proposed solutions had to follow existing practice as closely as possible and to be compatible with the educational level of chemical tanker crews. Last but not least, costs to both autorities and ship owners had to be minimal.
