Cone Penetration Test (CPT) is a in situ testing method, which characteries is quick, continuous data, penetration details, and rapid operation.Following the rapid development of offshore engineering , offshore CPT has been developed as an internationally recognized standard, and become more and more widely used in supporting the development of offshore industry. The paper introduces CPT equipment currently used in offshore geotechnical investigations, describes the seabed and downhole CPT systems, and discusses and comments on their application and interpretations. The paper may be used as reference for the development and applications of CPT technology in China.
