3D motion dynamics of axisymmetric bodies falling through water
Alsos, Hagbart Skage; Faltinsen, Odd Magnus (Journal article; Peer reviewed, 2018-12-01)A new simplified method for analysis of 3D motion dynamics of axisymmetric slender bodies falling from air through water is presented. Slender-body theory for potential flow of incompressible water is combined with 2D + t ... -
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 ... -
Effect of wave inhomogeneity on fatigue damage of mooring lines of a side-anchored floating bridge
Dai, Jian; Leira, Bernt Johan; Moan, Torgeir; Alsos, Hagbart Skage (Journal article; Peer reviewed, 2020)Mooring systems are important structural components of very long floating bridges. They effectively limit the transverse motions of the bridge under environmental loads. They also add viscous hydrodynamic damping to the ... -
Evaluation of Nonlinear Material Behavior for Offshore Structures Subjected to Accidental Actions
Storheim, Martin; Alsos, Hagbart Skage; Amdahl, Jørgen (ASME digital collection;OMAE-17-1044, Journal article; Peer reviewed, 2018-01-09)Evaluation of the nonlinear structural response of any structure is a challenging task; a range of input parameters are needed, most of which have significant statistical variabil- ity and the evaluations require a high ... -
LFCS Review report – Structure and mooring response - OC2018 A-073-WP3/WP4
Leira, Bernt; Kvittem, Marit Irene; Alsos, Hagbart Skage; Fylling, Ivar Johan (Research report, 2019-04-29)A review is performed on structural and mooring response analysis work in relation to Large Floating Coastal Structures and the planning of long floating bridges across fjords. The review contains observations on global ... -
On Common Research Needs for the Next Generation of Floating Support Structures
Aksnes, Vegard Øgård; Alsos, Hagbart Skage; Bachynski-Polic, Erin Elizabeth; Berthelsen, Petter Andreas; Delhaye, Virgile Roger; Furevik, Birgitte Rugaard; Jostad, Hans Petter; Kristiansen, Trygve; Ommani, Babak (Chapter; Peer reviewed, 2022)The world is facing several industrial and societal challenges, such as providing enough renewable energy and enough safe and healthy food as formulated in the United Nations sustainable development goals. Using floating ...
