Abstract. The paper presents the result of Pile Driving Analyzer (PDA) tests on pile<br />
foundation of an offshore structure located in East Kalimantan. The structure is<br />
supported by 4 (four) steel piles. There are no soil shear strength parameters<br />
available. The length of pile penetration into sea bed and the axial pile capacity is<br />
predicted based on PDA tests results. Only 2 PDA tests are allowed for monitoring<br />
the installation of the four piles. Back analysis, which is conducted based on wave<br />
propagation method, of pile driving based on result of PDA-test is conducted. The<br />
result is applied to recommend final set and refusal criteria for installation of the<br />
three remaining piles. The affect of set-up time on the axial bearing capacity of the<br />
pile is also studied. The results are comparable to those obtained by other<br />
researchers.<br />
Keywords: axial bearing capacity, driven pile, PDA, set-up time<br />
