Aarsæther, Karl Gunnar; Standal, Dag; Richardsen, Roger (SINTEF Fiskeri og Havbruk;A26774, Research report, 2015-01-26)Denne rapporten beskriver utviklingen i den norske fiskeflaten bade i form av teknisk utvikling i fartøy, hvordan rammebetingelsene og regulering har endret seg og også hvordan antall anløp har utviklet seg gjennom analyse ... -
D3.1 Fishery Pilot Definition
Granholm, Göran; Aarsæther, Karl Gunnar; Uriondo, Zigor; Quincozes, Iñaki; Jensen, Jørgen Haavind; Haugen, Joakim (Data-Driven Bioeconomy;D3.1, Research report, 2017-10-20)The objective of WP3 Fishery Pilot is to demonstrate how Big Data can boost the fishery sector. The Fishery Pilot focus is on two separate types of fisheries in two countries: Oceanic Tuna fisheries in Spain and small ... -
Development of a Simulator Training Platform for Fish Farm Operations
Holmen, Ingunn Marie; Thorvaldsen, Trine; Aarsæther, Karl Gunnar (ASME Proceedings | Structures, Safety and Reliability;OMAE2017-62023, Chapter, 2017-06)The Norwegian aquaculture industry is accident prone compared to other industries and employees report a high number of near-accidents. Furthermore, escape of fish is a challenge for the industry. There is a potential for ... -
Estimating the Physical Behaviour of Seine Ropes for Evaluating Demersal Seine Fishing Reporting on experiments in the flume tank
Madsen, Nina; Herrmann, Bent; Hansen, Kurt; Aarsæther, Karl Gunnar (SINTEF Fiskeri og havbruk;A26520, Research report, 2014-11-28)Demersal Seining is an active fishing method which is based on seine ropes and a seine net. The seine ropes and net are laid out on the fishing ground in a way that they encircle an aggregation of fish. Because the area ... -
Klimasatsing i kystfiskehavner: En analyse av energibruk på fangst- og mottaksleddet i kystfiskeflåten
Høyli, Randulf; Aarsæther, Karl Gunnar (SINTEF rapporter;2022:00185, Research report, 2022)Analyse av energibruk i fangst- og mottaksleddet viser at drivstofforbruk i flåteleddet representerer den største andelen av totalt energibruk for produksjon av ferskfisk, tørrfisk og frossenfisk. Vi finner at fartøy under ... -
Lumped, constrained cable modeling with explicit state-space formulation using an elastic version of Baumgarte stabilization
Skjong, Stian; Reite, Karl-Johan; Aarsæther, Karl Gunnar (Peer reviewed; Journal article, 2021)This paper presents a modeling approach for efficient simulation of slender structures, such as wires, cables and ropes. Lumped structural elements are connected using constraints. These are solved explicitly, using an ... -
Numerical Study of a Fishing Vessel Operating in Partially Ice Covered Waters
Aarsæther, Karl Gunnar; Su, Biao; Kristiansen, David (ASME digital collection;OMAE2018-77464, Chapter, 2018-06)The Arctic ocean has been the focus of increasing activities in oil and gas, marine traffic and fisheries as the resources in the Arctic area becomes more attractive for exploitation. There have been several studies on the ... -
Numerical Study of a Moored Structure in Moving Broken Ice Driven by Current and Wave
Su, Biao; Kristiansen, David; Aarsæther, Karl Gunnar (ASME Digital colletion;OMAE2017-61252, Chapter, 2017-06-25)This paper presents a numerical model intended to simulate the mooring load and the dynamic response of a moored structure in drifting ice. The mooring lines were explicitly modelled by using a generic cable model with a ... -
Numerical Study of a Single-Point Mooring Gravity Fish Cage With Different Deformation-Suppression Methods
Cheng, Hui; Aarsæther, Karl Gunnar; Li, Lin; Ong, Muk Chen (ASME Digital collection;OMAE2019-96079, Chapter, 2019-06)Compared to the multi-point mooring fish cage, the single point mooring (SPM) fish cage can spread out the accumulation of organic matter to prevent the local environment from being overwhelmed, and reduce the manufacturing ... -
NumSim - Numerical simulation of complex systems involving interaction between elements with large and varying stiffness properties
Kristiansen, David; Føre, Martin; Aarsæther, Karl Gunnar; Fredheim, Arne (SINTEF Fiskeri og Havbruk reports;A27066, Research report, 2015-07-31)This report is a short summa ry of the research activity and results obtained in the project Numsim - Numerical simulation of complex systems involving interaction between elements with large and varying stiffness properties. ... -

Arbeidet som presenteres er en oppdatering av et tidligere arbeid fra slutten av 2014, men med oppdatert datagrunnlag som strekker ... -
Predicting the effect of seine rope layout pattern and haul-in procedure on the effectiveness of demersal seine fishing: a computer simulation-based approach
Madsen, Nina; Aarsæther, Karl Gunnar; Herrmann, Bent (Journal article; Peer reviewed, 2017-08-03)Demersal Seining is an active fishing method applying two long seine ropes and a seine net. Demersal seining relies on fish responding to the seine rope as it moves during the fishing process. The seine ropes and net are ... -
