Dynamic Response of a Mobile Offshore Base Hydroelastic Test Model

Abstract

The objective of the work presented in this thesis deals with the study of dynamic response of a Mobile Offshore Base (MOB) hydroelastic test model. The MOB is a very large floating structure consisting of multiple self-propelled. semi-submersible modules. Physical scale model testing of a notional MOB concept has been conducted and the experimental results have been provided for one, two and four module configurations. This thesis focuses on utilizing the experimental data to understand the dynamic response of the MOB hydroelastic scale module. The analysis of the data is conducted using popular linear and nonlinear data processing techniques. The objectives are to obtain the modal shapes of the dynamic response, investigate the effect of connector dynamics in multi-module scale models and determine the nonlinear characteristics of the response.
