In this paper a practical engineering classification system for non-calcareous marine soils is proposed as an alternative to BS-5930 and ASTM-D2487. The system is based upon measurable data furnished by Atterberg limits and particle size distributions. This system is applied by means of simple flow charts for naming the main soil type (MST), the secondary soil type (SST) and the soil group symbol. These flow charts are easily adaptable in computer software and can be extended to include more categories. A total of 46 soil classes are possible in the new system. This paper also addresses differences between BS, ASTM and the new system and suggests consistency description criteria for fine and coarse grained soils. The system proposed in this paper is currently adopted by Fugro-McClelland Engineers (FME), The Netherlands in offshore soil investigations.
