During drilling a 110m offshore borehole, the existence of soil layers containing active hydrocarbon materials was investigated which a phenomenon is almost rare in geotechnical studies (the depth 60m up to end of borehole). The in-situ CPTU, sampling and experimental tests on undisturbed soil was performed.
Considering the limitations in the standards and similar experiences regarding soil contaminated with crude oil:
• Are there any standards which in defined soil-crude oil interaction in geotechnics?
• How to utilize the reduction factor on deep foundation design parameters including ultimate capacity, P-y, T-z, Q-z and SRD curves? The pile is OD= 60” thickness= 1” length= 85m and some part of pile will be penetrated in oily contaminated soil.
• What is the effect of contamination to mobilize shaft resistance in piles?
