This paper contains the investigation of behaviour of an articulated tower under waves loading. The tower is fixed to the bottom by hinge without friction. The regular wave loading is considered in this work. The numerical experiment in prepared. The tower is expected to move chaoticaly for some values of the wave or the tower parameters. Therefore the Lyapunow exponent will be investigated to characterize the behaviour of the tower.
