Influence of yaw-roll coupling on the behavior of a FPSO: An experimental and numerical investigation
(Journal article; Peer reviewed, 2015)An inconvenience in the experimental set-up of a FPSO in regular waves highlighted occurrence of parametric-roll events promoted by yaw-roll coupling and motivated a combined physical and numerical analysis on the relevance ... -
Influences of upstream extensions on flow around a curved cylinder
(Journal article; Peer reviewed, 2018)In simulations of flow around a concave curved cylinder, i.e. free-stream aligned with the plane of curvature and directed towards the inner face of the curvature, one cannot avoid interactions between the cylinder and the ... -
Information and Decision-making for Major Accident Prevention – A concept of information-based strategies for accident prevention
(Doctoral theses at NTNU;2022:379, Doctoral thesis, 2022)With wide application of sensors and digitalization for accident prevention and safety management of sociotechnical systems, distributed decision-makers rely on information supplied for their decision-making more than ever. ... -
Information-driven robotic sampling in the coastal ocean
(Journal article; Peer reviewed, 2018)Efficient sampling of coastal ocean processes, especially mechanisms such as upwelling and internal waves and their influence on primary production, is critical for understanding our changing oceans. Coupling robotic ... -
Inherent safety assessment: current state of the art and why is still not effectively adopted by industry
(Chapter, 2020)Inherent safety is a proactive approach to risk reduction. The industry should adopt it in the early stages of design as it is the most prominent approach to risk reduction, as described by experts. Researchers have worked ... -
Inhomogeneous wave load effects on a long, straight and side-anchored floating pontoon bridge
(Peer reviewed; Journal article, 2020)In this paper, we present a numerical study on the hydroelastic response of a 4.6 km long fjord crossing floating bridge subjected to wave loads. The bridge is straight in design and supported by 35 pontoons along its full ... -
Initial Design and Analysis of a Floating Bridge Concept
(Master thesis, 2017)The Norwegian government has an ambitious goal of connecting the Western coast of Norway with a ferry free road stretching from Kristiansand in the south to Trondheim in the north. This road has eight fjords which has to ... -
Initial Design of a Double Curved Floating Bridge and Global Hydrodynamic Responses Under Environmental Conditions
(Chapter, 2017)In this paper, a floating bridge concept is proposed. This bridge concept comprises a two oppositely curves in plan, which enables the cancellation of the axial forces at the bridge as one arch will be under compression ... -
Initial response mechanism and local contact stiffness analysis of the floating two-stage buffer collision-prevention system under ship colliding
(Peer reviewed; Journal article, 2021)A floating two-stage buffer collision-prevention system (FTBCPS) has been proposed to reduce the impact loads on the bridge pier in this paper. The anti-collision process can be mainly divided into two stages. First, reduce ... -
Innovating the Innovation System Thinking: a Systemism Model
(Journal article; Peer reviewed, 2023)The complexity of an innovation system, how it works and how to achieve high performance, represents a significant management challenge. As in any complex system, in an innovation system it is mandatory to operate with a ... -
Innovativ Metode for Installasjons Operasjoner på Dypt Vann
(Master thesis, 2019)Dette prosjektets hovedmaål var å undersøke to nye metoder for å installere subsea utstyr på dypt vann. Hovedfokuset har vært på metoden kalt ”Launch and Forget”. Tester har blitt gjennomført for å undersøke måter å forbedre ... -
