The model comprises a hybrid hydrodynamic model, which employs fully nonlinear potential theory (FNPT) for wave kinematic prediction and nondiffracting potential theory (NDPT) for wave force prediction, to simulate extreme wave and predict associated wave forces accurately and efficiently. Numerical simulation is carried out for the interaction of a floating TLPWT with waves. The focus is on the TLPWT motions, principally excited by higher-order harmonic wave forces. In particular, the springing responses generated by the third-order force at the triple wave frequency in regular waves are investigated, together with the wind turbine responses and tensions in the mooring lines.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43479797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A tabular iceberg towed in the Barents Sea in 2017, for which surveys of the underwater and surface parts were carried out, was selected for the analysis. As a result of numerical and physical modeling, the hydrodynamic characteristics of the iceberg were obtained for different motion courses; good convergence of the results of these methods was achieved. To determine each component, the numerical simulation, based on the equations of a viscous fluid motion, was carried out. Turbulent fluid flow is described by the Reynolds-averaged Navier–Stokes and continuity equations. The k – (cid:151) SST turbulence model is used to simulate turbulence. Numerical differentiation of the equations was performed in the open-source computational fluid dynamics software Open-FOAM. It is shown that the iceberg has several positions of stable and unstable equilibria in terms of the rotation around a vertical axis, and the influence of an iceberg’s orientation on additional resistance during rough seas is considered. Obtained results may be used in planning tabular iceberg towing in different regions of the world, as well as in further studies of iceberg behavior under load.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47715744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since Taiwan is located in the circum-Pacific seismic belt, there is significant interest in assessing the behavior of a wind turbine subjected to seismic loading. Based on the flexible volume method, a finite element model was employed to quantify the contribution of foundation damping to overall damping of offshore wind turbines. The results show that foundation damping was estimated to contribute 1.28%–1.50% of critical damping to total offshore wind turbine damping. The soil–structure interaction effects have significant influence on seismic responses.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46960412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research was based on the array of experimental data on the flat ice properties studied during 2013-2017 expeditions in the Kara, Laptev and East Siberian seas and 2016-2019 work on the research site in the Khatanga bay of the Laptev sea. Analysis of various ice strength characteristics showed similarity of ice in the Russian Arctic seas and in the Pacific Ocean. The differences in the ice strength properties at different loading rates were determined, and the variation coefficients of ice strength parameters were estimated. Dependences on ice temperature were obtained for all ice strength characteristics, and show a good approximation that can be described by a linear law. Indenter and compressive strength correlations were reformed for various types of first-year ice. Regression equations were determined in order to estimate the bending strength of ice consoles; anomalous behavior of Young's modulus of ice was observed during tests of consoles. Results of the work can be used for calculating ice loads on offshore structures, as well as for assessing icebreaking capacity of vessels passing the Northern Sea Route.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41376175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
