An overview of the Oden Arctic Technology Research Cruise 2015 (OATRC2015) and numerical simulations performed with SAMS driven by data collected during the cruise
Lubbad, Raed; Løset, Sveinung; Lu, Wenjun; Tsarau, Andrei; van den Berg, Marnix (Journal article; Peer reviewed, 2018)In the autumn of 2015, the Norwegian University of Science and Technology (NTNU) and the Swedish Polar Research Secretariat (SPRS) performed a research cruise named the “Oden Arctic Technology Research Cruise 2015” ... -
Application of FhSim for the Analysis of Environmental Loads on a Complete Fish-Farm System
Tsarau, Andrei; Kristiansen, David (Chapter, 2019)Fish farming at exposed locations requires robust and reliable structures that facilitate sustainable, safe and efficient production. There is also a need for proper numerical tools and analysis methods that can be utilised ... -
Identification of spectral signature for in situ real-time monitoring of smoltification
Svendsen, Eirik; Volent, Zsolt; Schellewald, Christian; Tsarau, Andrei; Bjorgan, Asgeir; Venås, Birger; Bloecher, Nina; Bondø, Morten Steen; Føre, Martin; Jónsdóttir, Kristbjörg Edda; Stefansson, Sigurd Olav (Peer reviewed; Journal article, 2021)We describe the use of an optical hyperspectral sensing technique to identify the smoltification status of Atlantic salmon (Salmo salar) based on spectral signatures, thus potentially providing smolt producers with an ... -
A numerical framework for modelling the dynamics of open ocean aquaculture structures in viscous fluids
Martin, Tobias; Tsarau, Andrei; Bihs, Hans (Peer reviewed; Journal article, 2020)This paper presents a complete numerical framework for modelling open ocean aquaculture structures in waves and current using Computational Fluid Dynamics (CFD). A structural dynamics model is incorporated to account for ... -
Numerical Modelling of the Hydrodynamic Effects of Marine Operations in Broken Ice
Tsarau, Andrei (Doctoral thesis at NTNU;2015:281, Doctoral thesis, 2015)For sustainable offshore field development and safe navigation in the Arctic seas, reliable numerical models that are capable of simulating the interactions between structures, water and sea ice are needed. The Discrete ... -
Numerical study of closed rigid fish cages in waves and comparison with experimental data
Su, Biao; Tsarau, Andrei; Endresen, Per Christian; Kristiansen, David; Lader, Pål Furset (Journal article; Peer reviewed, 2021)Closed fish cages have gained increased interest in marine aquaculture. However, knowledge on the seakeeping behaviour of a floating closed cage and the influence of the contained water inside the cage are still limited. ... -
Overview of the results of the project ‘Loads on Structure and Waves in Ice’ (LS-WICE)
Tsarau, Andrei; Cheng, Sukun; Shen, Hayley; Herman, Agnieszka; Li, Hongtao; Evers, Karl-Ulrich; Sukhorukov, Sergiy (Journal article, 2019)As an attempt to investigate several major research questions related to ocean wave-ice interaction, the HYDRALAB+ Transnational Access project ‘Loads on Structure and Waves in Ice’ (LS-WICE) was conducted in the Large Ice ... -
A Parameterization Scheme for Wind Wave Modules that Includes the Sea Ice Thickness in the Marginal Ice Zone
Liu, Dongang; Yang, Qinghua; Tsarau, Andrei; HUANG, Yongtao; Li, Xuewei (Journal article, 2023)The global wave model WAVEWATCH III®; works well in open water. To simulate the propagation and attenuation of waves through ice-covered water, existing simulations have considered the influence of sea ice by adding the ... -
Simulator for Arctic Marine Structures (SAMS)
Lubbad, Raed; Løset, Sveinung; Lu, Wenjun; Tsarau, Andrei; van den Berg, Marnix (Chapter; Peer reviewed, 2018)As offshore activities in the Arctic constitute a relatively new field with only a handful of relevant operations to draw experience from, and since full-scale trials are extremely expensive, there is an expressed need for ... -
Sloshing in a rotating liquid inside a closed sea cage for fish farming
Tsarau, Andrei; Lugni, Claudio; Lucarelli, Alessia; Kristiansen, David; Lader, Pål Furset (Peer reviewed; Journal article, 2021)Sloshing in a sea cage with a slowly rotating liquid is investigated. The cage is axisymmetric, and the liquid is subjected to a nearly uniform angular velocity about the vertical axis of the cage. Both experimental and ... -
Towards a holistic digital twin solution for real-time monitoring of aquaculture net cage systems
Su, Biao; Bjørnson, Finn Olav; Tsarau, Andrei; Endresen, Per Christian; Ohrem, Sveinung Johan; Føre, Martin; Fagertun, Jan Tore; Pascal, Klebert; Kelasidi, Eleni; Bjelland, Hans Vanhauwaert (Peer reviewed; Journal article, 2023)Digital twins and relevant concepts are being applied in a wide variety of ways, and they are of most use when an actual real-world physical system or process (a physical twin) is changing over time and when measurement ...
