Økonomisk betydning av norsk havgående fiskeflåte - Den havgående fiskeflåtens bidrag til samfunnsøkonomisk verdiskaping
(SINTEF rapport;2022:00870 A, Research report, 2022-09-01)Fiskeflåten er utgangspunktet for all produksjon i den fiskeribaserte verdikjeden. Aktivitet skapes både bakover og framover i verdikjeden som en følge av virksomheten i fangstleddet. Analysene i denne rapporten har tatt ... -
An annual profile of the impacts of simulated oil spills on the Northeast Arctic cod and haddock fisherie
(Peer reviewed; Journal article, 2022)We simulate the combined natural and pollutant-induced survival of early life stages of NEA cod and haddock, and the impact on the adult populations in response to the time of a major oil spill in a single year. Our ... -
Managing size selectivity: the relevance of compulsory and alternative selection devices in the Northeast Atlantic bottom trawl fishery
(Peer reviewed; Journal article, 2022)Two decades of use of the compulsory selectivity gear configuration in the Northeast Atlantic bottom trawl fishery, which consists of a rigid sorting grid followed by a diamond mesh codend, have revealed problems with ... -
Quantification of catch composition in fisheries: A methodology and its application to compare biodegradable and nylon gillnets
(Peer reviewed; Journal article, 2022)When evaluating fishing gear catches, the focus is often on a few species as opposed to the entire catch. In some fisheries this can lead to ignoring major part of catch composition. Thus, there is a need for a more holistic ... -
Accounting for Uncertainties in Biodiversity Estimations: A New Methodology and Its Application to the Mesopelagic Sound Scattering Layer of the High Arctic
(Peer reviewed; Journal article, 2022)Measures of biological diversity (biodiversity) are important for monitoring the state of ecosystems. Several indices and methods are used to describe biodiversity from field observations. Marine faunal biodiversity is ... -
Effect of Extension Piece Design on Catch Patterns in a Mediterranean Bottom Trawl Fishery
(Peer reviewed; Journal article, 2022)The catch composition of bottom trawls is commonly refined and improved through changes in codend design. Measures like reducing the number of meshes in codend circumference or turning diamond netting by 90 degrees are ... -
Comparison of laboratory wave generation techniques on response of a large monopile in irregular sea
(Peer reviewed; Journal article, 2022)As the offshore wind industry moves toward larger monopile turbines, model testing and validation of hydrodynamic load models become more important for new designs of turbines. Wave generation is an important aspect of ... -
Seatonomy applied in operational analysis of an autonomous net cleaning robot - NetClean 24/7 report for work package H1.1: Operational analysis and overall system design
(SINTEF rapport;2022:01107 A, Research report, 2022-09-23)This report presents an analysis of the autonomous cleaning operations handled in the NetClean 24/7 project. The analysis was conducted using the Autonomous Job Analysis (AJA) concept introduced in the Seatonomy method. ... -
Prediction of potential net panel selectivity in mesopelagic trawls
(Peer reviewed; Journal article, 2022)The growing interest in harvesting mesopelagic fish species has increased the need for knowledge about how trawls should be designed for optimizing the catch efficiency of these resources. Since the net herding efficiency ... -
Validation Methodology for Assessment of New ENavServices
(Chapter; Peer reviewed, 2022)The international maritime industry is on a current wave of digitalization and there is a dire need to enable an effective prediction of the different digital solutions, especially in terms of international implementation ... -
State-of-the-Art Review of Vortex-Induced Motions of Floating Offshore Wind Turbine Structures
(Peer reviewed; Journal article, 2022)The motivation for this study is the fast development of floating offshore wind energy and the immature methodology and engineering practice related to predictions of vortex-induced motions (VIM). Benefiting from the oil ... -
Contrasting phytoplankton-zooplankton distributions observed through autonomous platforms, in-situ optical sensors and discrete sampling
(Peer reviewed; Journal article, 2022)Plankton distributions are remarkably ‘patchy’ in the ocean. In this study, we investigated the contrasting phytoplankton-zooplankton distributions in relation to wind mixing events in waters around a biodiversity-rich ... -
T90 Codends Improve the Size Selectivity and Catch Efficiency of Shrimp Trawl Fisheries for Southern Velvet Shrimp (Metapenaeopsis palmensis) in the South China Sea
(Peer reviewed; Journal article, 2022)In order to obtain gear-based management instruments of shrimp trawl fishery for southern velvet shrimp in the South China Sea (SCS), the size selectivity and catch efficiency of four codends were tested and compared. These ... -
