    • Climatic Forecasting of Wind and Waves Using Fuzzy Inference Systems 

      Stefanakos, Christos; Vanem, Erik (ASME Proceedings | Structures, Safety and Reliability;OMAE2017-61968, Chapter, 2017-06-25)
      Wind and wave climatic simulations are of great interest in a number of different applications, including the design and operation of ships and offshore structures, marine energy generation, aquaculture and coastal ...

    • Comparison of Wind and Wave Extremes in Very Long-Term Climatic Scales 

      Stefanakos, Christos; Vanem, Erik (ASME Digital colletion;OMAE2018-77581, Chapter, 2018-06-17)
      The study of very long-term ocean climate is of great interest in a number of different applications. In a climate change perspective, estimations of return values of wind and wave parameters to a future climate are of ...

    • Effect of modelling inhomogeneous wave conditions on structural responses of a very long floating bridge 

      Dai, Jian; Stefanakos, Christos; Leira, Bernt Johan; Alsos, Hagbart Skage (Peer reviewed; Journal article, 2021)
      Floating bridges are suitable for connecting land parcels separated by wide and deep waterbodies. However, when the span of the crossing becomes very long, the water environment exhibits inhomogeneities which introduce ...

    • Fuzzy time series forecasting of nonstationary wind and wave data 

      Stefanakos, Christos (Journal article; Peer reviewed, 2016-07-15)
      In this paper, the well-known Fuzzy Inference Systems (FIS) in combination with Adaptive Network-based Fuzzy Inference Systems (ANFIS) are coupled for the first time with a nonstationary time series modelling for an improved ...

    • Global wind and wave climate based on two reanalysis databases: ECMWF ERA5 and NCEP CFSR 

      Stefanakos, Christos (Peer reviewed; Journal article, 2021)
      In the present work, the global wind and wave climate is studied on the basis of two well-known reanalysis products, namely ERA5 and CFSR-W (WW3 hereafter). Several statistical features of the datasets are assessed, such ...

    • Intercomparison of Wave Reanalysis based on ERA5 and WW3 Databases 

      Stefanakos, Christos (Journal article; Peer reviewed, 2019-06)
      In this work an intercomparison of two wave reanalysis products, namely ERA5 and CFSR-W (WW3 hereafter), is presented. The datasets are assessed by means of several statistical features, such as seasonal variability, ...

    • Investigation of inhomogeneous wave conditions in Sulafjorden 

      Stefanakos, Christos; Dai, Jian; Leira, Bernt Johan (Chapter; Peer reviewed, 2021)
      Complex fjord topography (bathymetry and coastline) may differentiate significantly wave conditions not only compared with the offshore ones but in the vicinity of few tens of meters. In the present work, possible ...

    • LFCS Review report - Environmental conditions Wind, wave and current in coastal areas 

      Fergestad, Dag; Økland, Ole David; Stefanakos, Christos; Stansberg, Carl Trygve; Croonenborghs, Eloïse; Eliassen, Lene; Eidnes, Grim (SINTEF Ocean AS rapporter;OC2018 A‐073 - WP1, Research report, 2018-07-12)
      A review is performed on the description of evironmental conditions in Norwegian coastal areas in relation to Large Floating Coastal Structures and the planning of long floating bridges across fjords. First, an outline of ...

    • Nonstationary fuzzy forecasting of wind and wave climate in very long-term scales 

      Stefanakos, Christos; Vanem, Eric (Journal article; Peer reviewed, 2018-06)
      Global climate change may have serious impact on human activities in coastal and other areas. Climate change may affect the degree of storminess and, hence, change the wind-driven ocean wave climate. This may affect the ...
