A linear mathematical model representing the dynamics of offshore towers is considered. An on-line identification scheme is proposed to estimate the modal parameters by using noisy response measurements obtained during tower normal operation. A technique is presented to extract the damping and stiffness matrices required for incipient failure detection from the identified modal parameters. An illustrative numerical example is presented.
