Dam-Break Waves’ Hydrodynamics on Composite Bathymetry
(Peer reviewed; Journal article, 2022)Among others, dam-break waves are a common representation for tsunami waves near- or on-shore as well as for large storm waves riding on top of storm surge water levels at coasts. These extreme hydrodynamic events are a ... -
Damage and Failure in an X65 Steel Pipeline Caused by Trawl Gear Impact
(Chapter, 2013)Offshore pipelines subjected to accidental impact loads from trawl gear or anchors may experience large global deformations and large local strains, creating a complex stress and strain history. In this study experiments ... -
Damage assessment for GRP submerged buoyancy
(Master thesis, 2016)Submerged buoyancy is used for many different subsea applications, especially with reliving connections between the seabed and surface installations. As CSUB specialises in composites structures for subsea installations, ... -
Damage Assessment of Sevan 1000 FPSO Subjected to Impacts from Shuttle Tankers
(Master thesis, 2018)Floating, production, storage and offloading (FPSO) units are the only viable option for oil and gas production in deep waters. Shuttle tankers are normally employed for cargo transfer because they are the most practical ... -
Damage Assessment of Sevan FPSO Subjected to Impacts From Shuttle Tankers
(Master thesis, 2014)Platform-ship collisions are fortunately rare events, but as the development of the offshore and oil industry and the gradually frequently used offloading operation, accidents become more and more frequent. The consequences ... -
Damage Detection Applied to a Full-Scale Steel Bridge Using Temporal Momens
(Peer reviewed; Journal article, 2020)The most common damages in existing highway and railway steel bridges are related to fatigue and are, as reported in the literature, found in the structural system of the bridge deck. This paper proposes a methodology for ... -
Damage detection in structures using subspace identification
(Master thesis, 2021)Alle konstruksjoner blir utsatt for skader, og konsekvensene kan være fatale. Hvis en skade blir oppdaget før konstruksjonen når brudd kan nødvendige tiltak iverksettes for å forhindre kollaps og øke sikkerheten for ... -

Damage identification of a jacket support structure for offshore wind turbines
(Chapter, 2020)Offshore jacket structures are regarded as a suitable type of support structure for offshore wind turbines in immediate water depths. Because of the welded tubular members used and environmental conditions, offshore jackets ... -
Damage Identification of an Offshore Wind Turbine Jacket Support Structure
(Master thesis, 2014)Due to the variable and stochastic offshore environment, offshore wind turbines are prone to fatigue. Fatigue damage usually occurs as cracks and is an important indicator of the structure's condition and the remaining ... -
Damage Identification of Structures with Accelerometers Under Idealized Conditions
(Master thesis, 2020)Dagens vei og jernbanenett består av et stort antall bruer som enten nærmer seg eller har overskredet levetiden som ble lagt til grunn for dimensjonering av disse konstruksjonene. Det er ikke økonomisk å erstatte disse ... -

Damage interaction analysis of ship collisions
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:208, Doctoral thesis, 2013)During its lifetime, a ship may encounter accidents, such as collision and grounding, for which damage consequences in the forms of loss of human life, pollution of the environment, and economic losses may be substantial. ... -
Damped steady-state resonant sloshing in a circular base container
(Journal article; Peer reviewed, 2018)To describe the damped resonant sloshing in a circular base container, the nonlinear modal equations by Faltinsen et al (2016 J. Fluid Mech. 804 608–45) are equipped with linear damping terms associated with the logarithmic ... -
Dampening of wood batch combustion heat release using a phase change material heat storage: Material selection and heat storage property optimization
(Journal article; Peer reviewed, 2016)The use of wood stoves for space heating in energy effective residential buildings can be problematic due to the batch combustion giving a highly transient heat production and the limited regulation of the combustion ... -
Dampgenerering i en solfanger
(Master thesis, 2013)Av praktiske og kulturelle årsaker har ikke tradisjonelle solkokere blitt implementert i landlige områder i afrikanske land. I områder med dårlig eller ikke-eksisterende strømnett blir mye tid brukt på å finne biodrivstoff ... -
Damping and Stiffness Characteristics of Shallow Offshore Foundations
(Master thesis, 2020)Målet med denne oppgaven er å etablere et enkelt rammeverk for å estimere fundamentnivåets demping og stivhet for grunne fundamenter i forskjellige jordtyper og med varierende fundamentgeometrier, uten å måtte utføre ... -
Damping in Timber Structures
(Doctoral Theses at NTNU, 1503-8181; 2012:263, Doctoral thesis, 2012)Key point to development of environmentally friendly timber structures, appropriate to urban ways of living, is the development of high-rise timber buildings. Comfort properties are nowadays one of the main limitations to ... -
Damping Measurements on a Multi-Blade Cascade with Multiple Degrees of Freedom: A Francis-99 Test Case
(Journal article; Peer reviewed, 2019)Due to thinner blades and higher demands for flexibility, the high-head Francis runners designed today face considerable challenges that severely affect the runners' expected lifetime. For many high-head Francis runners, ... -
Dampmotstand til klebefelt i kombinerte undertak og vindsperrer
(Master thesis, 2022)Strengere krav til tetthet og energibruk, samt økt fokus på bærekraft, har ført til at teip og klebede løsninger er hyppig brukt i moderne bygninger. Tetthet mot luft og fukt bidrar til beskyttelse av konstruksjonen slik ...
