The proposed research aims to develop a fully coupled fluid-solid interaction algorithm and code to model the non-linear dynamic response of flexible risers due to vortex induced vibration in deep waters. The coupled field problem will be solved using a field partitioning approach by decomposition of the space discretization and splitting of the time discretization within its time step intervals. The partitioned approach lends itself in a natural way to parallel computation in which the problem is decomposed into a number of sub-domains all of which can be concurrently processed for time-stepping. The time series output from this phase of the work will be used as input to a predictive fretting fatigue model of composite flexible risers which will also be developed in the second phase of the project. The fluid-solid interaction riser model will be validated using real measurement data which will be provided by the project's industrial collaborators. The fretting fatigue model will also be validated by conducting in-house tests on riser components which will lead to life-improving modifications under the controlled conditions of laboratory experiments.
