Biological response in organisms collected near the discharge point of the wastewater treatment plant of Stavanger
(Studentoppgave/UIS-TN-IKBM/2021;, Master thesis, 2021-06-01)The effluent from the IVAR SNJ wastewater treatment plant is discharged into the marine recipient Håsteinsfjord in the North Sea, 1.6 kilometers from the coast of the Stavanger peninsula. The treated discharged wastewater ... -
Carbon footprint assessment of the Vega subsea field – a preliminary study for the environmental footprint
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)Subsea tie-in fields on the Norwegian continental shelf (NCS) appear to have extremely low greenhouse gas intensity based on available environmental data, as emissions related to offshore oil and gas processing is reported ... -
Current wastewater treatment methods and emerging technologies with a focus on removal of pharmaceuticals.
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06)The global consumption of pharmaceuticals is increasing, and in recent years there has been a growing concern surrounding the release of pharmaceuticals to the environment. Wastewater treatment plants (WWTP) have been ... -
Development of new Corrosion Inhibitors
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)Pipelines are an essential part of the oil ang gas industry as they are the main means of transportation. As the offshore technology advances, subsea pipelines are being operated in more demanding environments. In field ... -
Faunal and Microbial Sediment Community Disturbances Caused by Organic and Inorganic Contamination
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06)There are ongoing developments to enable treatment of oil based drill cuttings with subsequent deposition offshore rather than the current practice to transport and treat such material on land. A sample from a step in the ... -
