Repair methods for damaged pipeline beyond diving depth
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)Mechanical damage of a subsea pipeline is found as one of the most severe concern in management of pipeline integrity. The need to reach and bring the hydrocarbons from the fields located in deep and ultra-deep waters, ... -
Requirements Elicitation for Barrier Monitoring System
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-07-10)The activities undertaken by operator companies in the Norwegian Continental Shelf pose a very high risk to human life and the environment. Leading causes of accidents are poor maintenance, inadequate risk assessment and ... -
Research of the influence of marine residual fuel composition on sedimentation due to incompatibility
(Peer reviewed; Journal article, 2021)The article shows studies of the problem of active sediment formation during mixing of residual fuels, caused by the manifestation of incompatibility. To preserve the quality and reduce sediment formation during transshipment, ... -
Research Risk Factors in Monitoring Well Drilling—A Case Study Using Machine Learning Methods
(Peer reviewed; Journal article, 2021)This article takes an approach to creating a machine learning model for the oil and gas industry. This task is dedicated to the most up-to-date issues of machine learning and artificial intelligence. One of the goals of ... -
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 ... -
