Two numerical models are used to simulate physical experiments of wave groups interacting with a fixed FPSO-like structure. Specifically, the propagation of the waves is modelled with a Lagrangian 2D model, while the 3D wave-structure interaction is resolved in OpenFOAMR. Using the Lagrangian model to construct the numerical equivalent of the experimental basin and wavemaker allows the very accurate reproduction the incoming wave conditions. Lagrangian computations of surface elevation and kinematics are then used as boundary conditions of a much smaller Numerical Wave Tank (NWT) created in OpenFOAMR. Absorbing boundary conditions are implemented at the far end of the OpenFOAMRtank to suppress reflections. Results of wave run-up and pressure on the structure's surface are presented in the form requested for the blind tests. date: 2018-06-10 date_type: published publisher: International Society of Offshore and Polar Engineers official_url: http://www.isope.org/wp-content/uploads/2017/10/ISOPE-2018_General-Info_0821-web.pdf full_text_type: other language: eng verified: verified_manual elements_id: 1587875 isbn_13: 9781880653876 lyricists_name: Buldakov, Eugeny lyricists_id: EBULD04 actors_name: Buldakov, Eugeny actors_id: EBULD04 actors_role: owner full_text_status: restricted series: International Ocean and Polar Engineering Conference (Offshore and Polar Engineering Conference) ) publication: Proceedings of the International Offshore and Polar Engineering Conference volume: 2018 place_of_pub: Sapporo, Japan pagerange: 1486-1491 event_title: 28th International Ocean and Polar Engineering Conference (Offshore and Polar Engineering Conference) ) issn: 1555-1792 book_title: Proceedings of the 28th International Ocean and Polar Engineering Conference (Offshore and Polar Engineering Conference) ) citation: Higuera, P; Buldakov, E; Stagonas, D; (2018) Numerical modelling of wave interaction with an FPSO using a combination of OpenFOAM R and Lagrangian models.
