Assessing environmental impact of discharge to sea from producing subsea installation with DREAM following life cycle thinking: a preliminary study for the environmental footprint
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)The purpose of this study was to quantify the environmental footprint of discharge to sea from a producing subsea installation and its semi-submersible host platform in the North Sea. Portion of environmental burden that ... -
Assessment of oil contaminated sediment toxicity using in vitro bioassay based on fish cell lines.
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-14)A series of oil-contaminated sediment samples (drill cuttings) have been analyzed for their toxicity using in vitro bioassay based on fish cell lines. Drill cuttings are pieces of rock that come out of a well, (a deep hole ... -
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 ... -
