Performance on the individual length control method of lifting cables for correcting verticality during suction penetration of pile was evaluated. Model tests were performed to compare and analyze for verticality correction results and cable tension for different number of installed lifting cables and inclination condition. Model test results showed that verticality of suction piles were successfully corrected during penetration by eccentricity resulted from different cable tension induced by differently adjusted length of each cables according to inclination position. Field tests were performed to evaluate field applicability. The inclination of pile was corrected by lifting cable length control during penetration. Especially, the verticality correction at the pullout stage was more effective compared with suction penetration stage in spite of slight pullout. Therefore, individual control of lifting cables during suction penetration can be applied for verticality correction of suction pile. And the accurate verticality of pile could be achieved by adding pullout process during penetration of suction pile.
