The cone penetration test (CPT) is the dominant in situ testing technique for marine soil investigations. Occasionally, acquired CPT data exhibit anomalies which can cause uncertainties about use in geotechnical design of offshore structures. Examples of such anomalies are u/sub 2/ pore pressure anomalies, temperature influence on cone resistance and sinking of a seafloor template used for cone penetration testing. This paper presents selected examples of such anomalies in CPT data and assessments of opportunities for post-processing of the data for correction of results when that can be justified and when it is not warranted.
