How Loads Interact? A Numerical Investigation of Aluminum Stiffened Panels Under Bi-Axial and Lateral Loads
(Chapter, 2023)Due to low weight, aluminum alloys are commonly used to build ferries, working boats and high-speed ships. The hull of such vessels can be designed as catamaran and trimaran for favorable hydrodynamical behavior and ... -
How safe were vessels during research cruises in Arctic in 2007-2019? Linking the Ice Watch Data and the Polar Operational Limits Assessment Risk Index System
(Chapter, 2021)The present work analyzes cruise data from the Ice Watch database and applies the IMO's Polar Operational Limit Assessment Risk Indexing System (POLARIS) with ice observations. The results of this study showed that on ... -
How vortex dynamics affects the structural load in step cylinder flow
(Journal article; Peer reviewed, 2023)The vortex dynamics and the structural load in a step cylinder (consisting of a small, d, and a large, D, cylinder) flow are investigated numerically at Reynolds number (ReD) 150 for diameter ratios D/d=2.0,2.4 and 2.8. ... -
Hull Dimensions of a Semi-Submersible Rig: A Parametric Optimization Approach
(Master thesis, 2013)Semi-submersible rigs are utilized to perform drilling, production and intervention operations in the oil and gas industry. The design of the rigs is a complex task which today is highly dependent on manual iteration and ... -
Hull Monitoring and Assessment of Hatch Corners and Hatch Opening Distortion
(Master thesis, 2015)Torsion is highly important for large container carriers. In order to maximize the container capacity, a large deck area is essential, which often leads to a big bow are. To simplify loading and ooading, each cargo hold ... -
Human and Organizational Factors in Vessel-Platform Collision Risk on the Norwegian Continental Shelf
(Master thesis, 2015)The accident potential of a vessel colliding with an offshore platform is significant, concerning both human lives, the environment and financial loss. To quantify and model the risk of collisions in an accurate manner has ... -
Human Factors Evaluation in Ship Design: A Case Study on Offshore Supply Vessels in the Norwegian Sea, Part I: Theoretical Background and Technical Constructs
(Journal article, 2016)Surveys were conducted in the Norwegian Sea to evaluate the existing human factors standards and their implementations on two different offshore supply vessels designs. The results are reported in two parts. This paper ... -
Human Factors in Ship Design and Operation: A Preliminary Survey of the Theoretical Construct
(Journal article, 2016)This technical note presents an analysis of the underlying factors of human factors in ship design based on questionnaires distributed on two offshore supply vessels operating in the Norwegian Sea. The concept of human ... -
Human Factors in Ship Design and Operation: Experiential Learning
(Doctoral thesis at NTNU;2016:11, Doctoral thesis, 2016)Human error and other human related factors have long been identified as the main cause of accidents at sea. Inadequate design has been suggested as a significant reason triggering human actions. In this research, human ... -
Human Factors on Offshore Supply Vessels in the Norwegian Sea - An Explanatory Survey
(Journal article, 2016)A survey of human factors on two state-of-the-art offshore supply vessels (OSVs) operating in the Norwegian Sea was performed by means of questionnaires. The purpose of the study was to examine whether human factors had ... -
Human Reliability Analysis of a safety operator on an autonomous passenger ferry
(Master thesis, 2023)Når selskapet Zeabuz forsøker å utvikle sin egen autonome passasjerferge, oppsto problemet med den menneskelige påliteligheten med hensyn til systemet. Den største bekymringen for denne masteroppgaven er å finne ut om den ... -
Human Reliability Analysis of Operator in Autonomous Shuttle Ferry
(Master thesis, 2021)Autonome fartøyer er et fremtredende konsept som tar sikte på å redusere kravet til menneskelig inngripen. I Trondheim er dette konseptet for tiden under testing. En autonom skyttelferge er under konstruksjon for å gjøre ... -
Human Reliability and the Impact of Control Function Allocation in the Design of Dynamic Positioning Systems
(Journal article; Peer reviewed, 2019)The design and function allocation of control in complex technological systems have mainly been technology-driven, resulting in increased automation. A human or user perspective is rarely taken in the technological ... -
Human Technical Factors in FPSO-Shuttle Tanker interactions and their influence on the Collision Risk during Operations in the North Sea
(Master thesis, 2014)Following a series of collisions and near-misses, involving shuttle tanker and FPSO performing tandem offloading operations in the North Sea, extensive effort was put to address the issue in the early 2000 s. The aim of ... -
Human-autonomy collaboration in supervisory risk control of autonomous ships
(Journal article; Peer reviewed, 2024)This paper presents a method for developing and testing a risk-based control system, as a first step towards including the human supervisor explicitly in the design of the system. The result is a control system with improved ... -
Human-system concurrent task analysis for maritime autonomous surface ship operation and safety
