Residual stress estimation in defect assessment procedures at weld toe and away locations on girth welds: Review of key parameters
(Peer reviewed; Journal article, 2020)The distribution of residual stresses in welded joints plays an important role within the fracture evaluation guidelines recommended in structural integrity assessment codes such as BS7910, API 579 RP-1/ASME FFS-1 and R6. ... -
Resonant Motions of Dynamic Offshore Structures in Large Waves
(Peer reviewed; Journal article, 2021-10)In marine engineering, the dynamics of fixed offshore structures (for oil and gas production or for wind turbines) are normally found by modelling of the motion by a classical mass-spring damped system. On slender offshore ... -
Response analysis of an offshore fish farm under combined waves and current.
(Master thesis, 2022)Global increasing demand for aquatic foods, limitations of sheltered water locations, and ecological concerns have led a movement towards expanding marine finfish aquaculture to exposed waters in the open ocean. Despite ... -
Response of primary and secondary systems under dynamic excitation
(Masteroppgave/UIS-TN-IKM/2010;, Master thesis, 2010)Engineers have gained much knowledge on how a primary system behaves under harmonic excitation and earthquakes, but they do not know as much about how a secondary system affects the behavior. In seismic areas, buildings ... -
Response sensitivity of a semisubmersible floating offshore wind turbine to different wind spectral models
(Peer reviewed; Journal article, 2020)Previous research on the OC3 spar floating offshore wind turbine (FOWT) has shown the sensitivity of the yaw and side-side modes' load and motion responses to different atmospheric conditions. Using the same baseline turbine ... -
Reuse of offshore steels for buildings: Lateral torsional buckling capacity of corroded beams
(Master thesis, 2023)The building industry is responsible for a lot of today’s CO2 emissions. The emissions from the building industry can be reduced by reusing steel from offshore structures. However, there are several challenges related to ... -
Reuse of structural steel components from decommissioned offshore structures
(Master thesis, 2023)This thesis presents the theoretical foundation for reusing steel from decommissioned offshore structures in onshore construction projects as a green alternative to new production steel. This would open up a new source of ... -

(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)Oppgåva omhandlar tiltrekking av skruer i forspente forbindelsar, og hadde som mål å oppdatere og revidere dei eksisterande prosedyrane for skruetiltrekking ved Bergen Group Rosenberg. Etter utsegn frå Rosenberg har ... -
Review and Optimization of Current Fatigue Analysis Models
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-13)The offshore oil and gas industry have been exposed to major challenges over the last decade, particularly demanding cost cuts and more effective technical solutions. Predictive systems and remaining life assessments for ... -
Review and recommendations of technical and organizational project execution: the case of the MEG project
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-16)With the growth in technology, projects and organizations today, many companies are struggling with the project execution process. The project execution process have to be both cost- and time-effective for companies to ... -
Review and synthesis of a walking machine (Robot) leg mechanism
(Peer reviewed; Journal article, 2019-08)A walking machine (robot) is a type of locomotion that operates by means of legs and/or wheels on rough terrain or flat surface. The performance of legged machines is greater than wheeled or tracked walking machines on an ... -
Review of environmental impact assessment methods and environmental assessment of high fly ash content concrete
(Master thesis, 2023)The construction industry is one of the main sources of pollution in the world with concrete and cement production accounting for at least 8% of the global greenhouse gas emissions. The recent increase in demand for ... -
A review of fatigue damage detection and measurement techniques
(Peer reviewed; Journal article, 2021-09)A vast amount of research has been carried out towards the goal of quantifying changes related to the fatigue damaging process in materials throughout the fatigue life. However, no recommended practice has been developed ... -
Review on fatigue life assessment methods for welded joints in orthotropic steel decks of long-span bridges
(Peer reviewed; Journal article, 2021)Orthotropic Steel Decks have been used in long-span bridges for several decades because of their high capacity to weight ratio. However, many fatigue related issues have been reported. This paper provides an overview of ... -
