Optimizing Jack-up vessel strategies for maintaining offshore wind farms
(Journal article; Peer reviewed, 2017-10)In this paper we present a new two-stage stochastic mathematical programming model that determines the optimal jack-up vessel strategy for an offshore wind farm. Given an offshore wind farm site, and distance to shore the ... -
Optimizing size selectivity and catch patterns for hake (Merluccius merluccius) and blue whiting (Micromesistius poutassou) by combining square mesh panel and codend designs
(Peer reviewed; Journal article, 2022)Gear modifications in fisheries are usually implemented to obtain catch patterns that meet management objectives. In the Basque bottom trawl fishery, gear regulations include the use of a square mesh panel (SMP) placed at ... -
Organic additive release from plastic to seawater is lower under deep-sea conditions
(Peer reviewed; Journal article, 2021)Plastic garbage patches at the ocean surface are symptomatic of a wider pollution affecting the whole marine environment. Sinking of plastic debris increasingly appears to be an important process in the global fate of ... -
Organic chemicals associated with rubber are more toxic to marine algae and bacteria than those of thermoplastics
(Journal article; Peer reviewed, 2023)The current study investigated the chemical complexity of fifty plastic (36) and elastomer/rubber (14) methanol extracts from consumer products, focusing on the association with toxicity in two screening assays (bacteria ... -
Organisational safety indicators in aquaculture – a preliminary study
(Chapter, 2017)The aquaculture industry has since the 70’s grown to become one of the most important industries in Norway. A safety challenge for the Norwegian fish farming companies is escape of salmon. During the last decade, the main ... -

In contrast to the other initiatives such as SIMMAN 2008 [1] and SIMMAN ... -
Outcomes of the DeepWind conceptual design
(Journal article, 2015)DeepWind has been presented as a novel floating offshore wind turbine concept with cost reduction potentials. Twelve international partners developed a Darrieus type floating turbine with new materials and technologies for ... -
Ova lipid profiling and egg quality in wild and captive lumpfish, Cyclopterus lumpus (Linnaeus, 1758)
(Peer reviewed; Journal article, 2022)Lumpfish (Cyclopterus lumpus) serves an important role as cleaner fish for removing salmon lice in salmon aquaculture. For this use, cultivated lumpfish are preferred over wild-caught fish to avoid overexploitation of ... -
Overexploitation, Recovery, and Warming of the Barents Sea Ecosystem During 1950–2013
(Peer reviewed; Journal article, 2021)The Barents Sea (BS) is a high-latitude shelf ecosystem with important fisheries, high and historically variable harvesting pressure, and ongoing high variability in climatic conditions. To quantify carbon flow pathways ... -
Overpumping av makrell (II) Effekt pa fangstkvalitet
(SINTEF Fiskeri og havbruk;A25816, Research report, 2014-01-27)Prosjektets hovedmål er å klarlegge hvorvidt det kan registreres forskjeller i makrellens kvalitet når den er pumpet direkte om bord i fangstfartøyet og når den er pumpet til et annet fartøy (overpumping). Kvaliteten på ... -
