Impact against offshore pipelines
(Master thesis, 2011)In 2007 a pipe at the Kvitebjørn oil field was impacted by an anchor and dragged out of its position. After the accident it was decided safe to run production, but later a leakage was found and the production was shut down. ... -
Impact against offshore pipelines
(Master thesis, 2010)In this thesis impact loads against offshore pipelines are studied. Impact loads are often associated with accidents, such as an anchor hooking. A pipeline subjected to an anchor hooking may experience severe deformations ... -
Impact Against Offshore Pipelines: Experiments and Numerical Simulations
(Master thesis, 2012)In the present thesis impact against offshore pipelines was studied. Incipient fracture in the pipes after impact was of special interest. The present work was a continuation of previous theses on the subject, and part of ... -
Impact against X65 offshore pipelines
(Doctoral thesis at NTNU;2014:362, Doctoral thesis, 2014)This thesis presents both experimental and numerical investigations into some of the plethora of parameters influencing pipeline impact behaviour and the potential fracture arising thereof. The seamless pipes studied are ... -
Impact against X65 steel pipes - An experimental investigation
(Journal article; Peer reviewed, 2013)Offshore pipelines subjected to accidental loads, such as impacts from trawl gear or anchors, may experience large global displacements from its initial position and large local strains. The axial forces set up during ... -
Impact analysis for a potential circular economy strategy for the plastic sector in Estonia
(Research report, 2023)This report presents the work of SINTEF’s collaboration with the Republic of Estonia Environment Agency through the project Enhanced Capacity on Circular Economy, funded by the Iceland, Lichtenstein, Norway Grants. This ... -
Impact analysis of flexible riser
(Master thesis, 2014)Research shows 35% of damage to flexible pipes occurs within the first year. A minimum of these failures are from poor design or manufacturing problems, since factories conduct Factory Acceptance Tests (FAT). Additionally, ... -
Impact assessment and adaptability of a building within a SPEN in a changing Climate: Robustness of BEP systems in terms of future climate , a study on impact of climate change using future climate model
(Master thesis, 2022)Klimaendringer er en åpenbar utfordring som sannsynligvis vil oppstå og være særegen i årene som kommer. Derfor, mens du planlegger for bærekraftige nabolag og fokuserer på vekst av bærekraft i byggesektoren, er det også ... -
Impact assessment of a wind turbine blade root during an offshore mating process
(Journal article; Peer reviewed, 2019)Single-blade installation is a popular method for installing blades on bottom-fixed offshore wind turbines. A jack-up crane vessel is often employed, and individual blades with their roots equipped with mechanical joints ... -
Impact assessment of Norwegian hydropower on freshwater fish species - an LCA approach
(Master thesis, 2016)Accounting for the total environmental impacts associated with energy technologies are becoming increasingly important due to large scale development of renewable resources. In order to assess the trade-offs between large ... -
Impact behavior of high-strength steel at low temperatures
(Chapter, 2018)A wide range of material and ballistic tests were conducted to explore the behavior of a high-strength steel at low temperatures. Our test program included quasi-static and dynamic uniaxial and notched tension tests, Charpy ... -
Impact behaviour of foam-based protective structures
(Master thesis, 2017)Foams are three dimensional cellular materials, with cell walls made up of a solid or liquid material and cells containing a gas or liquid. The solid material can be anything from a metal to a ceramic. Metallic and polymeric ... -
Impact Behaviour of Steel at Low Temperatures
(Master thesis, 2017)This thesis represents a continuation of the work carried out by Susanne Thomesen during her master's thesis in 2016. The primary objectives in this thesis were to determine the ballistic properties of the high strength ... -
Impact Behaviour of Steel at Low Temperatures
(Master thesis, 2016)The main objective of this thesis was to determine the impact behaviour of the high strength steel Strenx-960-Plus at room and low temperatures, and to investigate if the deformation and failure mode changed from ductile ... -
Impact behaviour of stiffened aluminium plates
(Master thesis, 2015)In this master thesis, impact loading against stiffened aluminium plates of the aluminium alloy AA6082-T6 was studied. The main objective was to study the behaviour of extruded aluminium profiles welded together when exposed ... -
Impact Behaviour of Stiffened Aluminium Plates
(Master thesis, 2016)In this master thesis stiffened aluminium plates of the aluminium alloy AA6082 subjected to impact loading was studied. The main objective was to study the behaviour of welded and stiffened aluminium plates exposed to ... -
Impact behaviour of stiffened steel plates
(Master thesis, 2015)The impact behavior of stiffened steel plates subjected to impact loading from concentrated loads was studied experimentally and numerically. Both dynamic and quasi-static tests of stiffened steel plates with geometry ... -
Impact from flexible operations on High Head Francis turbines
(Master thesis, 2018)Today the European energy grid contains more renewable energy sources than ever before, yet there is little to no research on how the increased amount affects the cost structure of the remaining energy sources of the grid. ... -
Impact Loading on Parts made of Injection-moulded PP
(Master thesis, 2015)This project is set as a part of the ongoing development of the constitutive model the SIMLab Polymer Model (SPM) developed at SIMLab, NTNU. The goal with this thesis is to explore the capabilities of this model using two ... -
Impact Loads on Circular Cylinders
(Master thesis, 2013)In the past, testing of water impact problems such as breaking waves impacting on risers, lowering of subsea structures through the splash zone and free fall lifeboat performance has been carried out either by model tests ...
