Abstract: A tool to provide predictive analysis and component stresses of an offshore platform supported by platform support members as the offshore platform is being placed within a body of water. The tool comprising a computer processor, computer data storage, an input means, and an output means, which can all be in communication with the computer processor. The tool comprises a rig model library comprising at least one individual rig model, wherein each of the individual rig models comprises a finite element analysis of a specific offshore platform and a database comprising calculated component stress values for each of a plurality of offshore platform components, wherein each of the calculated component stress values incorporate the finite element analysis of the specific offshore platform and a plurality of predictive parameters for predicting mechanical stresses and analyzing failure potential for rig placement.
