A Multibeam-Based SLAM Algorithm for Iceberg Mapping Using AUVs
(Journal article; Peer reviewed, 2018)Using autonomous underwater vehicles (AUVs) for mapping underwater topography of sea-ice and icebergs, or detecting keels of ice ridges, is foreseen as enabling technology in future Arctic marine operations. Wind, current, ... -
An Ice-Drift Estimation Algorithm Using Radar and Ship Motion Measurements
(Journal article; Peer reviewed, 2018)This paper presents a novel automatic real-time remote sensing algorithm that uses radar images and global positioning satellite system measurements to estimate the ice-drift velocity vector in a region around a free-floating ... -
Artificial intelligence for ship speed management during navigation in the Arctic
(Peer reviewed; Journal article, 2021)Difficult ice conditions are one of the major threats to ships, shipboard crew, and cargoes carried in Arctic waters. Ship-speed choice is influenced by many factors including the navigational conditions (ice, weather, ... -
Experimental Investigations of Breaking Wave Impact Forces on a Monopile Substructure for Offshore Wind Turbines Under Regular Breaking Waves
(Chapter, 2017)The main objective of the paper is to investigate wave impact forces from breaking waves on a monopile substructure for offshore wind turbine in shallow waters. This study examines the load assessment parameters relevant ... -
Ice Navigation in Arctic Offshore Wind Parks: Traffic Coordination Using Route Exchange and Moving Havens
(Peer reviewed; Journal article, 2023)New areas for the production of fossil-free renewable offshore energy production are planned in Arctic waters in the Bay of Bothnia, in the very north of the Baltic Sea between Sweden and Finland. These are waters normally ... -
Microstructure evolution of young sea ice from a Svalbard fjord using micro-CT analysis
(Peer reviewed; Journal article, 2021)We analysed the three-dimensional microstructure of sea ice by means of X-ray-micro computed tomography. Microscopic (brine- and air- pore sizes, numbers and connectivity) and macroscopic (salinity, density, porosity) ... -
Optimal Force Allocation for Overconstrained Cable-Driven Parallel Robots: Continuously Differentiable Solutions With Assessment of Computational Efficiency
(Peer reviewed; Journal article, 2020)In this article, we present a novel method for force allocation for overconstrained cable-driven parallel robot setups that guarantees continuously differentiable cable forces and allows for small penalized errors in the ... -
Risk assessments in the Norwegian aquaculture industry: Status and improved practice
(Journal article; Peer reviewed, 2018)The Norwegian aquaculture industry has the potential to become the country’s leading ocean industry in the future. More than 99% of the produced biomass is Atlantic salmon and trout. Norwegian fish farming is characterised ... -
Ship Traffic Organization with Moving Havens: Ship and Shore Perspective
(Chapter, 2020)e-Navigation is a concept launched by the IMO in 2006. The point is to share digital data to the benefit of safety, efficiency and the environment. Every ship must make a voyage plan before leaving berth. Sharing such ... -
Simplifying interactions between autonomous and conventional ships with e-Navigation
(Journal article; Peer reviewed, 2019)Ships in autonomous mode will for a long time interact with conventional ships with human decision-makers on the bridge. For safety it will be necessary to simplify this interaction and this paper discusses three areas ...
