Offshore Materials and Corrosion Engineering
Course Overview
This training is designed to provide the engineering background for analyzing piping systems on an offshore floating system, particularly, the Floating Production, Storage, and Offloading (FPSO) Unit. Peculiar sources of overstress on an FPSO are the hog/sag displacements as a result of the ship/vessel accelerations due to wave actions and loading/unloading scenarios.
This training will provide an in-sight to the FPSO piping stress design philosophies and considerations, understanding of the various load cases, hands-on techniques to solving various stress issues, and general stress analysis report presentation.
At the conclusion of this training, attendees should be able to use CAESAR II to analyze any piping system on an FPSO; model building, including as inputs the various hog/sag/structural displacements and blast load considerations.
