This paper evaluates the applicability of five current direct cone penetration test (CPT and CPTu) methods, to calculate the ultimate bearing capacity of 13 circular steel driven friction piles, which were driven in marine environments of Iran, in comparison to pile driving analyzer (PDA) data. PDA data was used to determine the measured load bearing capacities from dynamic testing. Pile capacities determined from the different methods were compared with the measured pile capacity obtained during dynamic testing. Four statistical criteria were selected as bases of evaluation. Results of the compression showed that the CPT and CPTu methods have acceptable accuracy to calculate the axial bearing capacity of piles. Therefore, a combination of CPTu data with dynamic test results can be considered by engineers for calculating the axial bearing capacity of piles in offshore structure practices.
