Energy efficient and climate friendly refrigeration systems onboard fishing vessels
(Chapter, 2023)Refrigeration systems onboard fishing vessels are necessary to keep the catch at a low temperature and to ensure long shelf life. Most refrigeration systems in the world fishing fleet still have R-22 as a working fluid, ... -
Energy flow analysis of an industrial ammonia refrigeration system and potential for a cold thermal energy storage
(Science et technique du froid;, Chapter; Peer reviewed, 2022)There is an increasing effort to reduce energy demand at food processing plants, mainly to reduce the total carbon footprint. The energy demand of a fish processing plant (using ammonia as refrigerant) has been evaluated ... -
Energy measurements onboard pelagic purse seiner
(SINTEF Rapport;, Research report, 2021-02-12)This report describes a research cruise carried out on a pelagic purse seiner during the autumn 2020 on the North Sea. The cruise was carried out to perform an assessment of the energy efficiency of the onboard RSW ... -
Ensilering av restråstoff fra hvitfiskflåten
(SINTEF Fiskeri og havbruk;A24644, Research report, 2013-08-19)I dette forprosjektet er det gjennomført vurderinger av mulighetene for ensilering av restråstoff i hvitfiskflåten. Det er gjort vurderinger av investeringskostnader, driftskostnader og prispotensial, logistikk og teknologiske ... -
Environmental Description in the Design of Fish Farms at Exposed Locations
(ASME Proceedings | Ocean Space Utilization;OMAE2017-61531, Chapter, 2017-06-25)This paper addresses the description of exposure from waves and currents in coastal regions for design of marine fish farms. Representative descriptions of environmental conditions are important inputs to the design and ... -
Environmental regulations in shipping: Policies leaning towards globalization of scrubbers deserve scrutiny
(Journal article; Peer reviewed, 2016-08)ABSTRACT Emission regulations for Sulphur oxides (SOx) and nitrogen oxides (NOx) are motivated by health- and other environmental objectives in local and regional settings, while global warming concerns motivate policies ... -
Environmental Taxation in Transport
(Journal article, 2016)Abstract For the purpose of providing public goods (e.g. air quality, congestion management and greenhouse gas mitigation), the transportation sector employs – and should employ – imperfect policy instruments, such as fuel ... -
Erfaringer og analyser fra drift av oppdrettsanlegg på eksponerte lokaliteter
(SINTEF Fiskeri og havbruk rapporter;A22528, Research report, 2012-03-29)Dette forprosjektet har hatt som mål å legge til rette for videreutvikling av forskningsrelaterte problemstillinger innen tema drift av eksponerte oppdrettslokaliteter. Eksponerte lokaliteter er her derfor å forstå som ... -
Erosion Dynamics of Cultivated Kelp, Saccharina latissima, and Implications for Environmental Management and Carbon Sequestration
(Peer reviewed; Journal article, 2021)A growing trend of interest for the cultivation of kelp is driven by predictions for high global demands of important commodities, which require the development of alternative supplies of natural resources. In this study ... -
Escape, discard and landing probability of Nephrops norvegicus in the Mediterranean Sea creel fishery
(Peer reviewed; Journal article, 2022)Size selection in creel fishery consists of two processes: the first taking place in the creel on the seabed and the second made by the fisher on the vessel. However, no study has ever considered both processes when assessing ... -
Escape, discard, and landing probability in multispecies Mediterranean bottom-trawl fishery
(Peer reviewed; Journal article, 2021)Commercial bycatch species and their exploitation pattern in the Mediterranean trawl fishery are little studied. The present work examines the overall size-selection pattern, both regarding the trawl in the sea and the ... -
EspyInsideFunction.jl-extracting intermediate results from numerical functions
(Peer reviewed; Journal article, 2022)EspyInsideFunction allows to write software in the Julia programming language Julia (2017) [1] to make the value of variables within a function’s local scope — variables that are neither arguments nor return values, available ... -
Establishing a link between composition and toxicity of offshore produced waters using comprehensive analysis techniques – A way forward for discharge monitoring?
(Journal article; Peer reviewed, 2019)Extracts of produced waters from five mature Norwegian Sea oil fields were examined as total organic extracts (TOEs) and after fractionation into operationally-defined ‘polar’ and ‘apolar’ fractions. The TOEs and fractions ... -
Establishing a Method for Electrical Immobilization of Whitefish on Board Fishing Vessels
(Peer reviewed; Journal article, 2021)A downscaled version of an electrical dry stunner used in aquaculture has been adapted for use on fishing vessels to immobilize the catch (cod, haddock and saithe) shortly after capture to facilitate immediate and easy ... -
Estimating overall size-selection pattern in the bottom trawl fishery for four economically important fish species in the Mediterranean Sea
(Peer reviewed; Journal article, 2021)The management of multispecies fisheries, such as the Mediterranean bottom trawl fishery, is always a challenge. However, information on gear selectivity and discards has been studied separately so far. In this paper, the ... -
Estimating Surface Concentrations of Calanus finmarchicus Using Standardised Satellite-Derived Enhanced RGB Imagery
(Peer reviewed; Journal article, 2023)Calanus finmarchicus is a keystone zooplankton species that is commercially harvested and is critical in sustaining many important fisheries in the North Atlantic. However, due to their patchy population distributions, ... -
Estimating the Physical Behaviour of Seine Ropes for Evaluating Demersal Seine Fishing Reporting on experiments in the flume tank
(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 ... -
Estimation of Directional Sea Spectra from Ship Motions in Sea Trials
(Journal article; Peer reviewed, 2017)This paper compares the skill of two algorithms that enable real-time estimation of the directional wave spectra exciting a ship from its measured motions. One algorithm consists of a nonlinear optimization of a parametric ... -
Estimation of fish catch potential using assimilation of synthetic measurements with an individual-based model
(Journal article; Peer reviewed, 2023)A large fraction of costs in wild fisheries are fuel related, and while much of the costs are related to gear used and stock targeted, search for fishing grounds also contributes to fuel costs. Lack of knowledge on the ... -
