Weathering study of TOR II and evaluation of oil weathering properties on Eldfisk S and Ekofisk J - In relation to oil spill response and evaluation of the predicted behaviour relative to previous studies of Ekofisk oils - OC2022 A-050
(SINTEF Ocean rapporter;OC2022 A-050, Research report, 2022-05-19)SINTEF Ocean has performed a standardized small-scale weathering study, including dispersibility testing, on TOR II. Limited laboratory studies were conducted for Ekofisk J and Eldfisk S to compare the weathering properties ... -
Make it simpler and better: T90 codend improves size selectivity and catch efficiency compared with the grid-and-diamond mesh codend in the Northeast Atlantic bottom trawl fishery for gadoids
(Peer reviewed; Journal article, 2021)The use of a sorting grid followed by a size-selective codend with minimum 130 mm mesh size is compulsory in the Northeast Atlantic demersal trawl fishery targeting cod (Gadus morhua), haddock (Melanogrammus aeglefinus), ... -
Paradigms to assess the human health risks of nano- and microplastics
(Peer reviewed; Journal article, 2021)Human exposure to nano- and microplastics (NMPs) has raised major societal concerns, yet no framework to assess the risks of NMPs for human health exists. A substantial proportion of plastic produced worldwide is not ... -
Conceptual System Dynamics and Agent-Based Modelling Simulation of Interorganisational Fairness in Food Value Chains: Research Agenda and Case Studies
(Peer reviewed; Journal article, 2022)System dynamics and agent-based simulation modelling approaches have a potential as tools to evaluate the impact of policy related decision making in food value chains. The context is that a food value chain involves flows ... -
Model tests of a hydroelastic truncated floating bridge
(Peer reviewed; Journal article, 2022)Literature on tank tests of floating bridges is extremely rare, while a very limited number of publications covering tests of other types of very large floating structures exist. Here, the authors share their experience ... -
Ship-Shore Interaction: The Model in the Middle
(Peer reviewed; Journal article, 2022)The complex picture of maritime transport involving more than 100 thousand ships, more than 8000 ports and a large number of stakeholders fulfilling different roles and being responsible for different processes means that ... -
Levels of autonomy for ships
(Peer reviewed; Journal article, 2022)This paper gives a summary of previously published papers on the definition of autonomy for ships, how this relates to different crewing regimes, and the terminology to be used. A conclusion is that autonomy should be ... -
The Importance of Documenting Autonomous Tests
(Peer reviewed; Journal article, 2022)This paper presents how autonomous tests can be documented and why this is important. A test area in Norway, more specifically the Trondheimsfjorden Test Area for Autonomous Ships, is used as a pilot to conduct tests with ... -
Offshore field experiments with in-situ burning of oil: Emissions and burn efficiency
(Peer reviewed; Journal article, 2021)In situ burning (ISB) is an oil spill response technique including ignition and burning to remove oil on the water surface. The technique rapidly and effectively removes large portions of the oil. However, the combustion ... -
Greenhouse gas emissions of Norwegian seafoods: From comprehensive to simplified assessment
(Peer reviewed; Journal article, 2021)The seafood sector is facing difficulties to meet the increasing demand for product greenhouse gas emission (GHG) assessments. We quantified GHGs of important seafood products of Norway, the world's second largest seafood ... -
Optimal ship lifetime fuel and power system selection
(Peer reviewed; Journal article, 2021)Alternative fuels and fuel-flexible ships are often seen as promising solutions for achieving significant greenhouse gas reductions in shipping. We formulate the selection of alternative fuels and corresponding ship power ... -
New insights into submarine tailing disposal for a reduced environmental footprint: Lessons learnt from Norwegian fjords
(Peer reviewed; Journal article, 2022)Submarine tailing disposal (STD) in fjords from land-based mines is common practice in Norway and takes place in other regions worldwide. We synthesize the results of a multidisciplinary programme on environmental impacts ... -
Experimental verification of the elastic response in a numeric model of a composite propeller blade with bend twist deformation
(Peer reviewed; Journal article, 2021)Adaptive composite propeller blades showing bend twist behaviour have received increasing interest from hydrodynamic and structural engineers. When exposed to periodic loading conditions, such propellers can be designed ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
(Peer reviewed; Journal article, 2021)In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, ... -
Assessing cyber threats for storyless systems
(Peer reviewed; Journal article, 2021)A proper assessment of potential cyber threats is vital for security decision-making. This becomes an even more challenging task when dealing with new system designs and industry sectors where there is little or no historical ... -
Robust adaptive backstepping DP control of ROVs
(Peer reviewed; Journal article, 2022)Dynamic positioning is an important control feature for an underwater remotely operated vehicle. This paper presents a nonlinear dynamic positioning controller suited for application to vehicles with model uncertainties, ... -
Optical measurement of tissue perfusion changes as an alternative to electrocardiography for heart rate monitoring in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Background: Welfare challenges in salmon farming highlights the need to improve understanding of the fish’s response to its environment and rearing operations. This can be achieved by monitoring physiological responses ... -
Exposure to low environmental copper concentrations does not affect survival and development in Atlantic cod (Gadus morhua) early life stages
(Peer reviewed; Journal article, 2021)In this study we investigated potential impacts of Cu exposure at low, environmentally relevant, concentrations on early live stages of Atlantic cod (Gadus morhua). Cod embryos and larvae were exposed to 0.5 μg/L (low), ... -
Assessment of random wave energy dissipation due to submerged aquatic plants in shallow water using deep water wave conditions
(Peer reviewed; Journal article, 2021)This article addresses the random wave energy dissipation due to submerged aquatic plants in shallow water based on deep water wave conditions including estimation of wave damping. The motivation is to provide a simple ... -
Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge
(Peer reviewed; Journal article, 2022)Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ...
