An approach to oil-content monitoring for bilge and ballast water discharge is described. Based on the assumption that safety, simplicity, and reliability are the three most important parameters for such a ship board installation, a scattering technique using solid-state lasers has been developed. The advantages and problems associated with using light scatter as a means of determining oil in water are described. Particular emphasis is placed on the importance of particle-size analysis and homogenisation of the oil/water sample. Results showing the response of a laser cell to different oils are given. These are directly related to the IMCO specifications for oil-content meters. A brief description of the problems encountered during the IMCO tests is given, together with a discussion of the "Black box" concept, which is a read-out of the automatic laser sampling of ballast water.
