The FOWT's platform and the WECs of the HOWiWaES are modeled as a single floating body with conventional rigid-body modes, while the motions of the WECs relative to the FOWT are described as additional generalized modes of motion. A numerical tool is established by appropriately modifying/extending the OpenFAST source code. The frequency-dependent exciting forces and hydrodynamic coefficients, as well as hydrostatic stiffness terms, are obtained using the traditional boundary integral equation method, whilst the generalized-mode shapes are determined by developing appropriate 3D vector shape functions. The tool is applied for a 5 MW FOWT with a spar-type floating platform and a conic WEC buoy hinged on it via a mechanical arm, and results are compared with those of other investigators utilizing the multi-body approach. Two distinctive cases of a pitching and a heaving WEC are considered. A quite good agreement is established, indicating the potential of the developed tool to model floating HOWiWaESs efficiently.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A Computational Framework for Fully Coupled Time-Domain Aero-Hydro-Servo-Elastic Analysis of Hybrid Offshore Wind and Wave Energy Systems by Deploying Generalized Modes","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-10-11 01:33:37.741605","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":"combined wind and wave utilization;hybrid offshore wind and wave energy systems;floating offshore wind turbines;wave energy converters;generalized-mode approach;numerical simulation;responses;turbine","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2026-09-28","DateCreate":"2026-09-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001624003800001","VABBcode":null,"OpenAcc":0,"DOI":"10.3390/jmse13112047"},"refs":null,"anarec":{"AnaID":448895,"PubliDate":2025,"Pagination":"2047","XtraPublOfAnaID":null,"ISBN":null,"Volume":"13","Issue":"11","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":251606,"SerRR":"Journal of Marine Science and Engineering.
