dc.description.abstract | DYNAMO (DYNAmic MOdels) is a computer program used to evaluate system dynamics models. This analysis determines the utility of the DYNAMO tool in the development of a roll-response predictor for an offshore drilling platform. The project consists of two major phases, including: 1. development of the theoretical model for the roll-response and definition of the application within the systems context, and 2. implementation of the theoretical model using DYNAMO. The results of the analysis demonstrate the success of DYNAMO application to the prediction of semi-submersible roll motion in regular sea states. The application successfully models the roll-response as a second-order differential equation of motion of a negative feedback system. The model is verified at semi-submersible heading angles of zero, forty-five, and ninety degrees with respect to the incident sea state. | en |
