WWS presents at the ICPC 2022 Plenary Conference

WWS CEO Carlos Pirmez presented a paper at the Annual meeting of the International Cable Protection Committee.  The paper, entitled “The impact of turbidity currents on submarine infrastructure: insights from subsea pipeline incidents and 3D numerical models“, described the impact of turbidity currents to a gas pipeline in the Philippines using detailed reconstruction of the flow and sediment movement on the seabed. An integrated atmospheric-coastal-deepwater modelling enabled forecasting which storms may pose a higher risk to the local infrastructure, providing the foundation of an Early Warning System for protection of the pipeline.  Co-authors in the presentation were: Michele Bolla Pittaluga and Gaetano Porcile (WWS), Octavio Sequeiros and Alessandro Frascatti (Shell), Elena Bastianon (Univ. of Hull) and Jasim Imran (Univ. of South Carolina).
