Abstract

A hydroelastic reduced scale model of a jacket-type offshore structure was designed and constructed according to the principles of physical similitude. The techniques employed for physical modeling, construction and experimental analysis are outlined briefly and some results from free and forced vibration tests are reported. Along with these test results, some comments are made on the damping-factor components obtained, effects of mass variation and changes on the vibration responses due to the loss of structural integrity.
