System integrity and holistic risk understanding
(Master thesis, 2013)The objective of an offshore topside process facility is to maximise production of the clean and marketable products: oil, natural gas and condensates. Safe and reliable operation is an absolute requirement to remain ... -
Improving Reliability Centered Maintenance Methodology for oil and gas application
(Master thesis, 2013)Traditional RCM approach concerns important functions of the system, and thoroughly obtained/selected PM action can certainly improve reliability of the system, but this approach cannot address and deal with all the aspects ... -
Analyse av mulige løsninger for stigerør og overflatefartøy for undervannsborerigg
(Master thesis, 2013)AbstractThis study gives an overview of the challenges that comes when petroleum activities is moving further north into an arctic environment. The arctic has new challenges, as cold hard weather, snow and ice. The marine ... -
Continuous-Curvature Path Generation using Fermat's Spiral
(Journal article; Peer reviewed, 2013)This paper proposes a novel methodology, based on Fermat's spiral (FS), for constructing curvature-continuous parametric paths in a plane. FS has a zero curvature at its origin, a property that allows it to be connected ... -
Dynamic Analysis and Design of Mooring Lines
(Master thesis, 2013)This master thesis presents a comparison study, where the main focus has been to assess if simplified methods can be used for analysing mooring lines for a turret moored FPSO in shallow waters. The MIMOSA program applies ... -
Load and response analysis of wind turbines under atmospheric icing and controller system faults with emphasis on spar type floating wind turbine
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:192, Doctoral thesis, 2013)Deep water offshore wind is a vast, reliable and economical energy source. Floating offshore wind turbines are potential systems to capture this energy which need to be analysed and designed in order to achieve economic ... -
Study on backscattering from fish school near pump intake
(Master thesis, 2013)In this master project, acoustic method was applied for estimating the gradually changed fish density during the crowding near the pump intake in salmon plant. The purpose was to detect if the sensitivity of the echo sounder ... -
Hydrodynamic Modeling of Tension Leg Platform Wind Turbines
(Chapter, 2013)In order to compute the system response of tension leg platform wind turbines (TLPWTs), it is important to accurately capture the hydrodynamic loading not only at the wave frequency, but also in the low (difference) and ... -
Comparative Study On Dynamic Responses of a Semi-submersible Wind Turbine Using a Simplified Aerodynamic Model and a BEM Model
(Master thesis, 2013)Due to the high potential of offshore wind energy, a lot of research work is being done around the world on offshore wind turbines. Currently mainly two types of model are used in Marine Technology Department of NTNU to ... -
Global Analysis of a Floating Bridge
(Master thesis, 2013)There is an ongoing political debate in Norway concerning how to improve the communication between communities on the western coastline. A proposed solution is to build floating bridges over some of the crossings that today ... -
THE DEVELOPMENT OF A MARITIME FREIGHT MODELING FRAMEWORK WITH AN APPLICATION IN LNG SHIPPING
(Master thesis, 2013)The dynamic, expansive, and integrated nature of global maritime freight transportation systems motivates the need for modeling tools that can effectively evaluate a highly diverse assortment of maritime freight systems ... -
Vortex Induced Vibrations Of Slender Marine Structures: Inverse Analysis
(Master thesis, 2013)With the development of the offshore engineering and the increasing of water depth, VIV (vortex induced vibrations) becomes a big challenge of the design of slender marine structures. In engineering field, we use some ... -
Looking with both eyes. Comments to Håkon Glørstad "Where are the Missing Boats? The Pioneer Settlement of Norway as Long-Term History"
(Journal article; Peer reviewed, 2013)Glørstad introduces his paper with a joke that ridicules searching for your keys in the illuminated areas only. After reading the paper one may wonder if he missed the point of his own joke. Anyway, it seems just as unwise ... -
Dynamic fault-detection in shipboard electric load sharing.
(Master thesis, 2013)The main contribution of this thesis is an investigation of dierent fault detection systems that canbe used for marine diesel electric power plants.The motivation of this thesis is to develop fault detection systems that ... -
A novel methodology for robust dynamic positioning of marine vessels: theory and experiments
(Journal article, 2013)The paper describes a novel robust adaptive controller for Dynamic Positioning (DP) of marine vessels. The proposed Robust Multiple Model Adaptive Dynamic Positioning (RMMADP) structure consists of a bank of robust controllers ... -
Response Analysis of Jacket Structure During Loadout Phase
(Master thesis, 2013)The purpose with this report is to verify that the Edvard Grieg jacket structure has sufficient strength to withstand the loads imposed during the load out operation at Kværner Verdal.The structural analysis has been ... -
Fatigue Crack Rrowth Simulation Using xEtended Finite Element Method
(Master thesis, 2013)Fatigue crack growth analysis of offshore structure is concerned by the industry because it?s economical and practical to increasing the usage life of the strucutre by extend it?s fatigue life. S-N approachs are the most ... -
Shipbuilding Cost Estimation: Parametric Approach
(Master thesis, 2013)A continuously increasing global competition in the ship building industry leads to decreasing margins and an increased cost pressure for Norwegian shipbuilders. The Norwegian ship designers and shipbuilders are known ... -
Structural resistance of polar ships to ice loading: Discussion of the IACS Polar rules considering different structural and methodological aspects
(Master thesis, 2013)Generally, the design of ships and offshore structures intended for operation in ice infested waters has been based upon elastic methods of plasticity. However, through development of knowledge regarding the true behaviour ... -
