Autonomous Path Planning and Maneuvering of a Surface Vessel
(Master thesis, 2020)Denne oppgaven tar for seg et intelligent veiledningskonsept for en overflatefarkost som beveger seg fra start- til endelig veipunkt. Problemet blir løst stegvis for å legge til rette for utførelse i sanntid og for å kunne ... -
Autonomous Path-Planning and -Following for a Marine Surface Robot
(Master thesis, 2017)Autonomous navigation for unmanned surface vessels is a modern and rapidly growing field of research. In recent years, many concepts and solutions have been proposed in order to achieve autonomous control of marine vessels. ... -
Autonomous Robotic Intervention using ROV
(Master thesis, 2016)This thesis proposes a semi-autonomous agent architecture for a Remotely Operated Vehicle (ROV). The purpose of this architecture is to apply control strategies from Autonomously Operated Vehicles (AUVs) onto ROVs, in order ... -
Autonomous Sailboats - Modeling, Simulation, Control
(Master thesis, 2016)This thesis is divided into five parts. In the first part, a general mathematical model of a sailboat is created. The model presented builds upon previous work and improves the modeling at multiple different areas such as ... -
Autonomous ship maneuvering with guaranteed safety
(Master thesis, 2021)Autonome skip følger vanligvis en nominell bane under en reise. Denne banen planlegges gjerne før reisen begynner. Kjente, statiske hindringer kan unngås gjennom planleggingen av den nominelle banen, i motsetning til ukjente ... -
Autonomous Ships - Combining Hybrid Control and Machine Learning
(Master thesis, 2019)Denne masteroppgaven utforsker hvordan man kan oppnå en høy grad av autonomi for et skip ved å utvikle et kontrollsystem som fører skipet fra A til B uten menneskelig innblanding. Et litteraturstudie av tidligere forskning ... -
Autonomous subsea intervention (SEAVENTION)
(Peer reviewed; Journal article, 2022)This paper presents the main results and latest developments in a 4-year project called autonomous subsea intervention (SEAVENTION). In the project we have developed new methods for autonomous inspection, maintenance and ... -
Autonomous Systems Design - An Exploratory Research Study in the Context of Maritime Shipping
(Master thesis, 2018)The maritime shipping industry is experiencing a rapid development towards utilizing autonomous systems to a greater extent. These systems are capable of decision-making and executing actions on behalf of or in cooperation ... -
Autonomous Systems Safety – State of the Art and Challenges
(Chapter, 2019)This whitepaper provided a starting point concerning some of the topics that were to be addressed at IWASS, including the current state of the art on autonomous systems development and challenges it faces. In the following ... -

Autonomous underwater vehicles in Arctic marine operations: Arctic marine research and ice monitoring
(Doctoral theses at NTNU;2018:255, Doctoral thesis, 2018)This thesis considers autonomous underwater vehicles (AUVs) in Arctic marine operations. It focuses on their use as a sensor platform in ice monitoring operations and the use of AUVs for Arctic marine research. Arctic AUV ... -
AutoVoyage: Autonom baneplanlegging, banegenerering, og banefølging for autonome skip under transit
(Master thesis, 2019)Denne avhandlingen presenterer et komplett system for autonom baneplanlegging, banegenerering og banefølging for et marint overflateskip. Baneplanleggeren er delt inn i en global planlegger med lav oppløsning, som planlegger ... -
AUV mission planning for Multiple Vehicles using Adaptive sampling
(Master thesis, 2020)Flere AUV-er brukes i dag i prøvetaking av havet for å studere hvordan marint liv i havet påvirkes av endringer på grunn av havfenomener som havfronter eller eddier. Havprøvetaking er ofte avhengig av forhåndsprogrammerte ... -
Availability Assessment of Electrically-Operated Blowout Preventers
(Master thesis, 2016)Offshore drilling industry is confronted with safety and environmental challenges imposed by the risk of oil and gas blowout accidents. The blowout preventer (BOP) has been an important safety-critical system for preventing ... -
Availability Estimation and Allocation for ERTMS
(Master thesis, 2019)This thesis focuses on the availability estimation by simulation, availability allocation and resilience assessment for railway systems. Firstly, a brief background of the railway has been given including history, ... -
Availability-based engineering resilience metric and its corresponding evaluation methodology
(Journal article; Peer reviewed, 2018)Several resilience metrics have been proposed for engineering systems (e.g., mechanical engineering, civil engineering, critical infrastructure, etc.); however, they are different from one another. Their difference is ... -
Averaged strain energy density criterion for rupture assessment of cracked rubbers: A novel method for determination of critical SED
(Journal article; Peer reviewed, 2018)In the present study, the application of averaged strain energy density (ASED) criterion has been extended to hyperelastic materials. Because of the material and geometry nonlinearities, commonly known for rubber-like ... -
Averaged strain energy density estimated rapidly from the nodal stresses by FEM for cracks under mixed mode loadings including the T-stress contribution
(Journal article; Peer reviewed, 2019)The present contribution reviews a recently proposed method to rapidly estimate the averaged SED at the tip of short as well as long cracks under in-plane I+II and long cracks under out-of-plane I+III mixed mode loadings. ...
