Local and global responses of a floating bridge under ship-girder collisions
(Journal article; Peer reviewed, 2018)The Norwegian Public Roads Administration is running a project “Ferry Free Coastal Route E39” to replace existing ferry crossings by bridges across eight fjords in western Norway. Since most of the fjords are wide and deep, ... -
Local Structural Analysis of a Semi-Submersible Exposed to Ice Loads
(Master thesis, 2015)The subject of deep sea drilling in the Arctic is now more relevant than ever. The environment in Arctic offshore areas can be extremely harsh and the structures operating there will have to be designed accordingly. In ... -
Localisation of Submarine Power Cables by Magnetometers on REMUS 100 AUV
(Master thesis, 2017)Power cables that are exposed to the marine environment are prone to damage, especially if they are located close to, or above, the seabed. Underwater surveys are carried out to ensure that cables are buried and inspect ... -
Localized corrosion damage prediction of steel plates in marine applications using quadrilateral inverse-shell elements based on iFEM
(Chapter, 2022)This research effort focuses on a damage detection strategy for identifying pitting corrosion locations in corroded marine structures using numerical approaches. To this end, a four-node quadrilateral inverse shell element ... -
Logistic management of production chemicals: A simulation Study
(Master thesis, 2011)This paper evaluates the logistics for production chemicals used on the offshore installations of the coast of Norway. Statoil provided the following problem description: There are an increasing number of fields on the ... -
Logistikkløsning for offshore oppdrettsanlegg
(Master thesis, 2012)Denne rapporten viser noen logistikkløsninger for offshore oppdrettsanlegg, og sammenligne de med dagens praksis. Bakgrunnen for oppgaven er de siste 20 årenes kontinuerlige stigning i volum av oppdrettslaks, en utvikling ... -
Long Term Analysis of Semi Submersible Offset
(Master thesis, 2016)The objective of this master's thesis is to perform a long term analysis of a non-linear response problem using the Peak Over Threshold (POT) method. Offset of a semi submersible was selected as suitable response problem ... -
Long Term Scheduling of Major Renewals: Systematic Approach and Financial Applications
(Master thesis, 2014)Much of the oil and gas installations in the North Sea originate from the booming 80s and 90s, and operators are facing considerable challenges in the managementof their ageing assets. Harsh environments combined with ... -
Long-term Analysis of Gear Loads in Fixed Offshore Wind Turbines Considering Ultimate Operational Loadings
(Journal article; Peer reviewed, 2013)The long-term extreme value analysis of gear transmitted load due to the main shaft torque is presented. Two methods, the multibody simulations (MBS) and a simplified method, are demonstrated for the gear transmitted load ... -
Long-term extreme response analysis of a long-span pontoon bridge
(Journal article; Peer reviewed, 2018)For the assessment of extreme load effects needed in design of marine structures, a full long-term analysis is recognized as the most accurate approach. However, due to the very large number of structural response analyses ... -
Long-Term Extreme Response Analysis of Marine Structures Using Inverse Reliability Methods
(Doctoral theses at NTNU;2017:298, Doctoral thesis, 2017)For the assessment of extreme responses needed in design of marine structures, a full long-term analysis is recognized as the most accurate approach. However, due to the very large number of structural response analyses ... -
Long-term extreme response analysis of marine structures using inverse SORM
(Chapter; Peer reviewed, 2017)In this paper the first order reliability method (FORM) found in connection with structural reliability analysis is first used in an inverse manner to efficiently obtain an approximate solution of the full long-term extreme ... -
Long-term extreme response and reliability of a vessel rolling in random beam seas
(Journal article; Peer reviewed, 2018)In this paper, the long-term extreme response of a vessel rolling in random beam seas and the associated reliability evaluation are addressed. The long-term response analysis is based on the upcrossing rates of the roll ... -
Long-Term Fatigue Damage Sensitivity to Wave Directionality in Extra Large Monopile Foundations
(Journal article, 2017)The fatigue damage sensitivity to wave directionality on large-diameter monopile foundations for use in the offshore wind turbine industry is investigated. A frequency domain approach with the Dirlik method is used for a ... -
Long-term joint distribution of environmental conditions in a Norwegian fjord for design of floating bridges
(Journal article; Peer reviewed, 2019)A floating bridge is an attractive solution for crossing wide and deep fjords. To design a reliable and cost-effective floating bridge, it is very important to accurately evaluate the long-term environmental conditions at ... -
Long-term Response Analysis of Wind Turbines with an Emphasis on Fault and Shutdown Conditions
(Doctoral thesis at NTNU;2014:266, Doctoral thesis, 2014)Wind turbines are exposed to a variety of load conditions during their 20-year service life. After installation, every turbine experiences operational, shutdown, and parked conditions, and any of these conditions might ... -
Long-term stochastic extreme response analysis of floating bridges
(Journal article; Peer reviewed, 2017)For the assessment of extreme responses needed in design of marine structures, a full long-term analysis is recognized as the most accurate approach. However, due to the very large number of structural response analyses ... -
Long-Term Wave Power Statistics for Individual Waves
(Master thesis, 2012)Long-term statistics for wave power describes the waves that will occur over years and their energy. This can be found by putting together short-term statistics for individual waves and statistics from sea states. All the ... -
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 ... -
