Pipeline Shore Crossing Approach in the Arctic Conditions
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)The energy demand will increase the development of new offshore areas including the Arctic region. The construction of new infrastructure will be required in the region, in particular, subsea pipelines. Considering the ... -
Pipeline shore crossing approaches in Arctic conditions
(Peer reviewed; Journal article, 2019)The development of the Arctic region will entail the construction of new infrastructure, in particular, subsea pipelines. Considering the lack of actual field practice, ecosystem vulnerability and lack of common Arctic ... -
Pipelines for development at deep water fields
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)Oil and gas fields are today being developed at water depths characterized as ultra-deep waters, in this report limited to 3500 meters. Pipelines, which are major components of these developments, will experience challenges ... -
Piping and structural interaction
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Structural and piping stress analyses are generally conducted separately in most of the situations. A pipe stress analysis is performed based on loads caused by pressure, temperature variations, weight of the pipe (with ... -

(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)In this master thesis the author carries out the research of the process piping integrity problems on ageing offshore installations located on the NCS in the context of M&M project activity. The author describes briefly ... -
Planning of a marine operation with focus on discussing limiting wave conditions
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-12)The planning of a specific marine operation done by Ocean Installer is carried out in this thesis with regards to weather conditions on the Norwegian Continental Shelf. This is done by looking into the wave statistics from ... -
Plugging and Abandoning Subsea Wells Using Light Well Intervention Vessels
(Master thesis, 2016-06-15)There are thousands of subsea wells in the world. The subsea industry is growing, more and more subsea wells are being developed. When the wells are no longer used, usually because they become unproductive, they need to ... -
Polar Ship Design and Operations: Past, Present, and Future
(Chapter, 2022)From an early emphasis on geographic exploration and exploitation of the resources in the polar offshore area (by hunting for walrus ivory teeth, seals, and whales), the focus is currently shifting toward the sustainable ... -
Polyurethane sealing discs on cleaning pigs-characterization and dynamic behaviour
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Pipeline pigging enhances flow rate and corrosion control. Pigging is made possible by the sealing element of the pig, of which polyurethane is the chief material used. Polyurethane raw materials are; polyols, isocyanates, ... -
Positioning of gas detectors at offshore installations
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)The safety level at offshore installations is considerably influenced by in which degree undesired gas releases are detected. The primary functions of a gas detection system are to detect the presence of gas and inform ... -
