Toward a holistic load model for structures in broken ice
(Journal article; Peer reviewed, 2015)Over the past decade we have seen an increase in marine operations in Arctic waters. Despite research and work on several offshore standards and ship rules, the ice loads on fixed and floating structures are not fully ... -
Toward a system of real-time prediction and monitoring ofbottom damage conditions during ship grounding
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:223, Doctoral thesis, 2011)This work o ers an analysis of the ship grounding process, examining a range of topics from the ability to predict the location of obstructions to a ship bottom's resistance to penetration and outer and inner hull plates' ... -
Toward adaptive robotic sampling of phytoplankton in the coastal ocean
(Journal article; Peer reviewed, 2019)Currents, wind, bathymetry, and freshwater runoff are some of the factors that make coastal waters heterogeneous, patchy, and scientifically interesting—where it is challenging to resolve the spatiotemporal variation within ... -
Towards an online risk model for autonomous marine systems (AMS)
(Peer reviewed; Journal article, 2022)Considering that few or no human operators are directly involved in the operation of Autonomous Marine Systems (AMS), an online risk model is necessary to enhance the intelligence of the AMS, its situation awareness, and ... -
Towards an online risk model for dynamic positioning operations
(Chapter, 2018)Automation and increasing complexity mean that operators have to handle data and alarms and emergent decisions under the pressure of unexpected and rapidly changing hazardous situations. Position loss during marine operations ... -
Towards automated identification of ice features for surface vessels using deep learning
(Journal article; Peer reviewed, 2019)Ship traffic in ice exposed areas is increasing, and ice navigation is largely a manual task. Despite the progress in machine learning and computer vision algorithms, little focus has been given to computer-aided scene ... -
Towards automated welfare monitoring of farmed salmon exploiting deep learning and computer vision
(Master thesis, 2021)Bevaring av fiskevelferd er et omfattende tema i oppdrettsnæringen. En industriell laksemerd kan inneholde så mange som 200 000 fisk, og det er utfordrende å overvåke velferden til denne mengden enkeltdyr. Manuelle ... -
Towards Autonomous Operations and Systems in Marine Archaeology
(Doctoral theses at NTNU;2018:203, Doctoral thesis, 2018)A large part of our common cultural heritage, ranging from submerged prehistoric landscapes to modern steel wrecks, lies on the seabed. For centuries they have remained protected by depth and remoteness, but are now under ... -
Towards Autonomous ROVs in Aquaculture: Implementation of Autonomous Mission Control for Unmanned Operations
(Master thesis, 2021)I denne oppgaven utformes og implementeres et autonomt system for oppdragskontroll av en autonom ROV, slik at den er i stand til å utføre autonome undervanns- inspeksjons-, vedlikeholds- og reparasjonsoppdrag innenfor ... -
Towards Autonomous Ships
(Master thesis, 2019)Hovedtemaet i denne masteroppgaven er situasjonsforståelse. Oppgaven er todelt, hvor første del handler om sjøtilstandsestimering for et dynamisk posisjonert (DP) fartøy, og andre del handler om risikobaserte beslutninger ... -
Towards autonomous underwater navigation and perception for end-to-end ship hull inspection
(Doctoral theses at NTNU;2024:68, Doctoral thesis, 2024)This thesis presents an innovative and integrated solution for end-to-end underwater ship hull inspection using a small and low-cost Remotely Operated Vehicle (ROV). In a world where maritime activities have significant ... -
Towards autonomy in ROV operations
(Journal article, 2015)This paper presents an on-going research project focusing on the development of technology to enable autonomy in ROV operations. The project is a collaborative project between Norwegian offshore industry and academia. ... -
Towards carbon-free mobility: The feasibility of hydrogen and ammonia as zero carbon fuels in spark ignition light-duty vehicles
(Journal article; Peer reviewed, 2024)Global warming is a major environmental issue caused by the release of greenhouse gases, such as carbon dioxide into the atmosphere. Light-duty vehicles (LDVs) including passenger cars and light-duty trucks, are a significant ... -

Towards contract-based verification for autonomous vessels
(Peer reviewed; Journal article, 2023)Design and verification of autonomous vessels represent a major interdisciplinary engineering challenge due to the combination of high system complexity and the interaction with dynamic, uncertain, and unstructured ... -
Towards gradient-based design optimization of fully-flexible tension-leg platform wind turbines
(Peer reviewed; Journal article, 2022)Novel technologies and design methods are needed to enable cost-competitive development of wind turbines with floating foundations. Tension-leg platforms have an established history in the oil and gas industry, though the ... -
Towards Remaining Life Assessment by use of Conditional Adversarial Networks
(Master thesis, 2021)Statistikk viser at fler-tallige tap av forankringsliner har skjedd tidlig i den designede levetiden. Forankringsliner av kjetting var ansvarlige for opptil 50 % av alle tap, hvor utmatting var en av hoved°arsakene for ... -
Towards Remaining Life Assessment Using Machine Learning
(Master thesis, 2021)Brudd i ankerkjettinger grunnet korrosjon og utmatting er et problem offshorenæringen møter. Brudd i flere kjettinger i permanent oppankrede systemer har vist seg å ha en årlig frekvens på omtrent 3 x 10^-3 og de fleste ... -
Towards Robust Autonomy of Underwater Vehicles in Arctic Operations
(Master thesis, 2019)Denne masteroppgaven undersøker verktøy og metoder for å utvikle mer robuste autonomiløsninger for autonome undervannsfarkoster (AUV) i arktiske underisoperasjoner. AUVer er effektive plattformer for tverrfaglig vitenskapelig ... -
