A Machine Vision System for Robust Sorting of Herring Fractions
(Journal article; Peer reviewed, 2016-07-16)Among the rest raw material in herring (Clupea harengus) fractions, produced during the filleting process of herring, there are high-value products such as roe and milt. As of today, there has been little or no major effort ... -
A meta-analysis of plaice size-selection data in otter trawl codends
(Journal article; Peer reviewed, 2020-07)The influence that mesh size, the number of open meshes around the circumference, twine thickness and catch size have on the size-selection of plaice (Pleuronectes platessa) in otter trawl codends is investigated by ... -
A metaheuristic solution method for optimizing vessel fleet size and mix for maintenance operations at offshore wind farms under uncertainty
(Journal article; Peer reviewed, 2017-10)Maintenance operations at offshore wind farms are challenging due to the offshore element; maintenance technicians and spare parts need to be transported from an onshore port or offshore station to the individual wind farm ... -
A model for optimal fleet composition of vessels for offshore wind farm maintenance
(Journal article; Peer reviewed, 2017)We present a discrete optimisation model that chooses an optimal fleet of vessels to support maintenance operations at Offshore Wind Farms (OFWs). The model is presented as a bi-level problem. On the first (tactical) level, ... -
A New Formulation for the Combined Maritime Fleet Deployment and Inventory Management Problem
(Journal article; Peer reviewed, 2017-09-27)This paper addresses the fleet deployment problem and in particular the treatment of inventory in the maritime case. A new model based on time-continuous formulation for the combined maritime fleet deployment and inventory ... -
A new Norwegian bioeconomy based on cultivation and processing of seaweeds: Opportunities and R&D needs
(SINTEF Fiskeri og Havbruk reports;A25981, Research report, 2014-06-03)Cultivation of macroalgae at the lowest trophic level, using only sunlight and nutrients from the sea while taking up CO:z, will have a neutral carbon footprint and the biomass will contribute significantly to meet the ... -
A non-invasive approach to assess texture changes in sous-vide cooked Atlantic mackerel during chilled storage by fluorescence imaging
(Journal article; Peer reviewed, 2018-10)The aim of this study was to investigate the potential of fluorescence microscopy coupled with chemical, physical and data analysis methods for reliable and non-invasive detection of changes in texture parameters of sous-vide ... -
A Numerical Study on Stratified Shear Layers With Relevance to Oil-Boom Failure
(ASME Digital colletion;OMAE2014-23981, Chapter, 2014-06)Interface dynamics of two-phase flow, with relevance for leakage of oil retained by mechanical oil barriers, is studied by means of a 2D lattice-Boltzmann method combined with a phase-field model for interface capturing. ... -
A Proposed New Laboratory Protocol for Dispersant Effectiveness Testing Adapted for Subsea Dispersant Injection
(Journal article, 2019-05)The main objective of this study is to develop a new protocol for bench-scale dispersant effectiveness testing adapted for subsea dispersants injection (SSDI). The new approach includes turbulence conditions, dispersant ... -
A rational approach to seepage flow effects on bottom friction beneath random waves
(Journal article; Peer reviewed, 2014-08)The bottom friction beneath random waves is predicted taking into account the effect of seepage flow. This is achieved by using wave friction factors for rough turbulent, smooth turbulent and laminar flow valid for regular ... -
A short review of the state-of-the-art of pneumatic oil barriers and bubble flotation at sea
(SINTEF Fiskeri og havbruk rapporter;A103024, Research report, 2010-03-22)The authors have reviewed sources of information relevant to the use of air bubbles to develop new technology for combating oil spills at sea, including an overview of the status of oil spill response in Norwegian waters. ... -
A Shortest Path Heuristic for Evaluating the Quality of Stowage Plans in Roll-On Roll-Off Liner Shipping
(Journal article; Peer reviewed, 2017-09-27)Roll-on Roll-off shipping companies transport rolling cargo, such as cars, trucks and large construction machines. When sailing, this type of cargo must be attached to the deck using chains, to prevent damaging the cargo. ... -
A spatio-temporal recurrent network for salmon feeding action recognition from underwater videos in aquaculture
(Journal article; Peer reviewed, 2019-11-12)Recent developments have shown that Deep Learning approaches are well suited for Human Action Recognition. On the other hand, the application of deep learning for action or behaviour recognition in other domains such as ... -
A survey on maritime fleet size and mix problems
(Journal article; Peer reviewed, 2014-06-01)This paper presents a literature survey on the fleet size and mix problem in maritime transportation. Fluctuations in the shipping market and frequent mismatches between fleet capacities and demands highlight the relevance ... -
