Summary This paper aims to investigate the possibility and effectiveness of applying a tuned liquid column damper (TLCD) to suppress pitching motion of a floating box structure. A mathematical model of the TLCD‐floating structure interaction system is developed, and the associated equations of motion are derived using a Lagrangian approach. Then, the procedures for numerically obtaining the optimum parameters of the TLCD for the undamped system under harmonic excitation are proposed using Den Hartog's method. The presented examples demonstrate that the TLCD can efficiently suppress the pitching motion of the floating box structure and has potential for applying to the development of floating housing.
