Abstract
This paper examines the origin of stony and bouldery soils offshore and describes the techniques and equipment available for their investigation. The experiences of the Norwegian Geotechnical Institute and British Geological Survey are reviewed in presenting a detailed discussion of direct drilling techniques, and the usefulness of indirect methods is also discussed. The applicability of statistical methods is briefly covered, and the paper concludes with a consideration of the foundation engineering implications of these geotechnically difficult materials.
