Mooring System Diagnosis and Structural Reliability Control for Position Moored Vessels
(Journal article; Peer reviewed, 2014)Early diagnosis and fault-tolerant control are essential for safe operation of floating platforms where mooring systems maintain vessel position and must withstand environmental loads. This paper considers two critical ... -
Mooring Systems For Floating Wind Turbine Farms In Deep Water
(Master thesis, 2020)Verdas energibehov aukar stadig, samtidig som global oppvarming og stigande temperaturar truar klima og miljø. Fornybare energikjelder må derfor utviklast. Havvind er ein veksande teknologi som kan bidra til å løyse denne ... -
Motion analysis of Semi-Submersible
(Master thesis, 2012)In this thesis the response variables (RAOs) of a semi submersible unit are inspected. Both operational and survival condition as well as a shallow draft are inspected. The survival condition is inspected with respect to ... -
Motion Compensation System for a Free Floating Surface Effect Ship
(Chapter, 2014)This paper deals with vertical motion compensation, or motion damping, on a freefloating Surface Effect Ship (SES) at zero speed. The Motion Compensation System (MCS) works by varying the air cushion pressure of a Surface ... -
motion control during offshore lift operations
(Master thesis, 2017)Offshore lifting is present in many offshore operations. Offshore lifting operations is very sensitive to environmental loads which reduces the weather window for the entire operation. The weather criteria for offshore ... -
Motion control problem in a multi-torus floating solar island concept, using tension cables - A 2D approach
(Master thesis, 2022)Flytende soløyer dukker opp som markeder og forskningsfelt, og noen akademiske og kommersialiserte flytende soløy-konsepter eksisterer eller er i drift. Ett akademisk konsept som er i en fase av forskning og utvikling er ... -
Motion Control Systems for ROVs - Underwater Path-Following for a Videoray Pro 4 ROV
(Master thesis, 2016)Remotely operated vehicles (ROVs) are used for an increasing amount of underwater applications, ranging from being hobby-related to having military and scientific interests. ROVs may incorporate automatic control strategies, ... -
Motion Feasibility Framework for Remotely Operated Vehicles Based on Dynamic Positioning Capability
(Peer reviewed; Journal article, 2021)Knowing whether a remotely operated vehicle (ROV) is able to operate at certain foreknown environmental conditions is a question relevant to different actors during the vehicle’s life cycle: during design stages, buying ... -
Motion of floating wind turbines
(Master thesis, 2010)Motion of floating wind turbines has been studied. A literature study on different concepts and what tools are available for simulating them is presented. Marintek’s simulation software SIMO is used for time simulations. ... -
The Motion of Slender, Cylindrical Bodies - An Experimental and Theoretical Investigation
(Master thesis, 2018)An accidentally dropped object in the sea can result in critical damage on pipelines, platform base structures and underwater installations. This has to be accounted for during offshore operations and installations. Earlier ... -
Motion response analysis of a Sevan FWT moonpool foundation
(Master thesis, 2022)Arbeidet som presenteres i denne rapporten er en masteroppgave for masterstudiet Marin Teknikk ved NTNU - Norges Teknisk-Naturvitenskapelige Universitet. Denne oppgaven er en numerisk og eksperimentell analyse hvor bevegelse ... -
Motion response prediction of marine vessels based on hydrodynamic models updated through on-site measurements.
(Chapter, 2022)Decision support systems in offshore vessels utilize wave parameters in combination with physics-based vessel models to predict the vessel behavior prior to the initiation and execution of a marine operation. These predictions ... -
Motion sensing on vessels operating in sea ice: A local monitoring system for transit and stationkeeping operations under the influence of sea ice
(Doctoral theses at NTNU;2019: 138, Doctoral thesis, 2019)The diminishing sea ice in the Arctic and Antarctic could lead to a higher number of ship operations in these areas, such as cargo transit, resource exploration, fishing, and tourism. However, despite the sea ice reduction, ... -
Moving element analysis of high-speed train-slab track system considering discrete rail pads
(Peer reviewed; Journal article, 2021)This paper presents a study of the dynamic behavior of a coupled train-slab track system considering discrete rail pads. The slab track is modeled as a three-layer Timoshenko beam. The study is carried out using the moving ... -
A multi-camera system for the integrated documentation of Underwater Cultural Heritage of high structural complexity; The case study of M/S Helma wreck
(Peer reviewed; Journal article, 2021)High structural complexity is quite common in underwater archaeological sites and perhaps on top of the list when it comes to challenges regarding 3D reconstruction. Advances in underwater robotics and optical sensors are ... -
