Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge
Dai, Jian; Abrahamsen, Bjørn Christian; Hansen Viuff, Thomas; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ... -
Effect of Wave-Current Interaction on Structural Responses of a Very Long and Side-Anchored Floating Bridge
Dai, Jian; Abrahamsen, Bjørn Christian; Leira, Bernt Johan (Chapter, 2020)This paper is concerned with a computational study on the hydroelastic response of a long, straight and side-anchored fjord-crossing floating bridge accounting for the wave-current interaction. The effect of this interaction ... -
Experimental analysis of high and steep wave impacts and related hydroelastic effects relevant for offshore structures in steel
Ahani, Alireza; Abrahamsen, Bjørn Christian; Greco, Marilena (Chapter, 2022)An experimental strategy to investigate high and steep wave impacts and related hydroelastic effects relevant for offshore structures in steel is proposed. A physical model was shaped as a vertical rectangular surface-piercing ... -
FSI Analysis of Abnormal Wave Slamming Events
Cao, Anni (Master thesis, 2020)Slamming impact is a hazardous phenomenon to ships and offshore structures, which is characterised by a highly nonlinear coupling interaction between the structure and the fluid. To evaluate it correctly and accurately is ... -
Hydroelastic response of concrete shells during impact on calm water
Abrahamsen, Bjørn Christian; Grytten, Frode; Hellan, Øyvind; Søreide, Tore H.; Faltinsen, Odd Magnus (Peer reviewed; Journal article, 2023)Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ... -
Hydroplastic response of a square plate due to impact on calm water
Abrahamsen, Bjørn Christian; Alsos, Hagbart Skage; Aune, Vegard; Fagerholt, Egil; Faltinsen, Odd Magnus; Hellan, Øyvind (Peer reviewed; Journal article, 2020)This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ... -
OMAE2017-62390 - Study of an Entrapped Air Pocket due to Sloshing Using Experiments and Numerical Simulations
Firoozkoohi, Reza; Abrahamsen, Bjørn Christian; Faltinsen, Odd Magnus (Chapter; Peer reviewed, 2017)The capability of the OpenFoam software to model slamming where air is entrapped between the free surface and the structure is investigated. The test case studied is a previously studied phenomenon, where an air pocket is ... -
Plated offshore structures exposed to violent wave impact – Slamming structural response
Næss, Håvard (Master thesis, 2021) -
Sloshing induced tank-roof impact with entrapped air pocket
Abrahamsen, Bjørn Christian (Doktoravhandlinger ved NTNU, 1503-8181; 2011:38, Doctoral thesis, 2011)
