Maintenance strategies for deep sea offshore wind turbines
(Journal article; Peer reviewed, 2010)Purpose – The objective of this paper is to outline a framework that guides the development of sound maintenance strategies and policies for deep‐sea offshore wind turbines. Design/methodology/approach – An important ... -
Major accident prevention illustrated by hydrocarbon leak case studies: A comparison between Brazilian and Norwegian offshore functional petroleum safety regulatory approaches
(Journal article; Peer reviewed, 2020)Despite laws, regulations, or risk management tools designed to avoid loss events, a hydrocarbon leak (HCL) in an offshore oil and gas platform1 is a major hazard event that reveals failures in risk control. In addition, ... -
Major Accidents in Exposed Fish Farming - A quantitative collision risk analysis
(Master thesis, 2018)The Norwegian aquaculture industry has had a large increase in activity over the last years, and the expansion is expected to continue in the years to come. However, a further expansion of traditional fish farming is not ... -
Major accidents in Norwegian fish farming
(Journal article; Peer reviewed, 2019)The Norwegian fish farming industry is experiencing accidents that may have serious consequences for fish-farm operators, the environment, and the farmed fish themselves. Fatalities and serious personnel injuries, mass ... -
Making sense of speed effects on ice crushing pressure-area relationships in IACS ice-strengthening rules for ships
(Journal article; Peer reviewed, 2021)Arctic shipping fleet expansion is anticipated in the future. However, future refinements in the understanding of ice loads on larger ships are needed to achieve a better structural design with reduced steel weight. Published ... -
Maneuvering and direction stability in restricted waters
(Master thesis, 2023)Denne avhandlinga kastar lys over den siste utviklinga innan manøvrerbarheit og retningstabilitet i avgrensa farvatn. Nyleg vart dette emnet kjent for offentlegheita då tankskipet Ever Given grunnstøtte diagonalt i ... -
Maneuvering and Seakeeping of a Single Ship and of Two Ships in Interaction
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:55, Doctoral thesis, 2008)The main objective of this thesis has been to study the maneuvering and seakeeping of two interacting ships. A systematic approach is adopted. First, the maneuvering behaviour of a single ship in regular waves was considered. ... -
Maneuvering of two Interacting Ships in Calm Water
(Chapter, 2010)The maneuvering of two interacting ships in calm water at Froude numbers less than ~0.2 and in water of infinite horizontal extent is studied based on an extended version of the maneuvering model for two ships by Skejic ... -
Maneuvering of two interacting ships in waves
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:361, Doctoral thesis, 2012)This thesis describes the development of a module based maneuvering prediction system for one ship or two interacting ships in calm water or waves. The work is a continuation and generalization of the previous work of ... -
Maneuvering with safety guarantees using control barrier functions
(Journal article; Peer reviewed, 2021)Control barrier functions (CBFs) ensure safety of controlled dynamical systems, by restricting the control inputs to render desired sets forward invariant. In this paper we propose a dynamic guidance scheme for autonomous ... -
Mapping accident reporting procedures in the maritime transportation sector
(Master thesis, 2010)This paper examines the accident reporting procedures in the maritime transportation sector. A parallel study, corresponding to this study, revealed a vast amount of underreporting by several western flag states. This is ... -
Mapping the Historical Shipwreck Figaro in the High Arctic Using Underwater Sensor-Carrying Robots
(Peer reviewed; Journal article, 2020)In 2007, a possible wreck site was discovered in Trygghamna, Isfjorden, Svalbard by the Norwegian Hydrographic Service. Using (1) a REMUS 100 autonomous underwater vehicle (AUV) equipped with a sidescan sonar (SSS) and (2) ... -
Marine Autonomous Exploration using a Lidar
(Master thesis, 2016)This thesis reviews the complete design of a control system on a marine surface vessel, capable of autonomous exploration in small-scale marine environments. This involves the development of strategies for map exploration, ... -
Marine Autonomous Exploration Using a Lidar and SLAM
(Chapter; Peer reviewed, 2017)This paper presents the implementation of a 2D-lidar to a model-scale surface vessel, and the design of a control system that makes the vessel able to perform autonomous exploration of a small-scale marine environment by ... -
Marine Crane Dynamics Lab - Modelling and experimental validation
(Master thesis, 2017)In this thesis, simulation models for a knuckleboom crane and its winch system have been developed. The simulation models have been used to design model based control laws for positioning the orientation of the crane joints ... -
