- Abstract
A dynamic model of offshore installation process is established for the large precise equipment. To prevent the precise equipment being damaged, vibration isolators are used to absorb the impact energy during the installation process. In this study, the motion of equipment consists of the vertical displacement and rotation based on the large size of equipment. In the model, the tensioning and relaxing of hoisting rope and the constraint from the installation platform are considered. Then, the Baumgartner method is used to modify the dynamic motions. After that, the maximal release velocity is evaluated on the basis of the limit acceleration of equipment according to the motion of winch. Besides, the effect of the different types of damping is investigated by numerical simulation. The results show that vibration isolator with quadratic damping has a better performance and can increase the performance conditions.
