Wave Forces on Offshore Structures Calculated with Smooth Particle Hydrodynamics and physical modeling.

Project Details

Description

Currently, computational fluid dynamics (CFD) models are utilized heavily in the aircraft and automotive industry for the computation of forces on the structures, but these models are not used in the oil industry for the design of offshore structures. (In fact, the design methodology for offshore design is the same as it was 40 years ago!) This project will show that a modern CFD code, GPUSPH, which is based on Smoothed Particle Hydrodynamics and has been shown to be appropriate for nonbreaking and breaking waves can be used for offshore structure design. As validation, we propose to model wave forces on two types of offshore structures—one similar to an offshore platform for oil & gas extraction, and the second, a floating wave energy device. The GPUSPH code is coupled with a multi-physics dynamics package Project Chrono to model the elastic behavior of the structures in the wave field.

Concurrent with the numerical modeling it is proposed to carry out physical model testing of the same devices, with different wave environments, to provide a detailed validation data set for the numerical model and to explore for unexpected results, as often happens with physical model testing. In particular, resonance and near-resonance conditions will be explored.

It is expected that the validated and extended (with Project Chrono) open source GPUSPH code will be useful for design in the offshore and wave energy converter industries. Further, the validated model will be used on elastic structures of oil drilling platform and wave energy. The complete physical model work will be done in Kuwait Institute for scientific Research and the numerical modeling in Northwestern University, USA.
