A methodology for identification of suitable drilling waste handling systems in the Arctic region
(Journal article; Peer reviewed; Tidsskriftartikkel, 2016)
As the demands to reduce the environmental impact of oil and gas operations increase in the Arctic region, the need to identify suitable waste handling systems become more essential. The aim of this paper is to propose a methodology for identifying suitable drilling waste handling system, by considering the distinctive operating condition of the Arctic region. The proposed methodology can help the ...
Bioremediation Treatment of Hydrocarbon-Contaminated Arctic Soils: Influencing Parameters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
An expert-based approach to production performance analysis of oil and gas facilities considering time-independent Arctic operating conditions
(Journal article; Tidsskriftartikkel, 2016-03)
The availability and throughput of offshore oil and gas plants operating in the Arctic are
adversely influenced by the harsh environmental conditions. One of the major challenges in
quantifying such effects is lack of adequate life data. The data collected in normal-climate
regions cannot effectively reflect the negative effects of harsh Arctic operating conditions on
the reliability, availability, ...
Dynamic spare parts transportation model for Arctic production facility
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-14)
Timely delivery of the required spare parts plays an important role in meeting the
availability target and reducing the downtime of production facilities. Spare parts logistics is
affected in complex ways while operating in the Arctic, since the area is sparsely populated and
has insufficient infrastructure. It is also greatly affected by the distinctive operational
environment of the region, ...
Trends in seismic data acquisition in areas with surface ice
(Peer reviewed; Bok; Chapter, 2019)
The Arctic has great significance in relation to the exploration and exploitation of its huge petroleum resources. Seismic surveys are the key part of petroleum exploration. Reflected sound waves are used to produce a 3D subsurface geological model, which helps to take a decision on drilling location for potential hydrocarbon resources. Seismic surveys are very complex operations, and growing energy ...
Road Transportation Challenges in the Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
Despite all efforts to mitigate global warming, its rate and magnitude are still rising where transportation is considered to be an important contributor. In the Arctic regions however, unstable weather conditions, strong seasonal variations, and long harsh winters result in additional challenges to transportation in different ways such as those related to environment, human health, safety, and ...
Observed and unobserved heterogeneity in failure data analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-08)
In reality, failure data are often collected under diffract operational conditions (covariates), leading to heterogeneity among the data. Heterogeneity can be classified as observed and unobserved heterogeneity. Un-observed heterogeneity is the effect of unknown, unrecorded, or missing covariates. In most reliability studies, the effect of unobserved covariates is neglected. This may lead to inaccurate ...
On RAM performance of production facilities operating under the Barents Sea harsh environmental conditions
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-05-19)
Oil and gas (O&G) industry is expanding its activities into Arctic offshore, where is characterised with severe operating conditions and less-developed infrastructure. Such conditions affect the reliability, availability, and maintainability (RAM) of offshore O&G plants, operations, and activities through different scenarios. Plant RAM analysis provides key information for decision-making on, for ...
Resilience of a transportation network: Importance of vulnerable nodes
(Conference object; Konferansebidrag, 2022)
Transportation Infrastructure is one of key critical infrastructures which are crucial for a wellfunctioning modern society. This study proposes a resilience-oriented framework for analyzing and ultimately mitigating risk and improving resilience for land transportation networks with a focus on vulnerable nodes. The framework uses network theory and considers the concept of independent pathways, ...
Sea-spray measurement tools and technique employed in marine icing field expeditions: A critical literature review and assessment using CFD simulations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-24)
Sea-spray icing resulting from sea spray droplets accreting on exposed surfaces poses a significant safety concern
for vessels and marine structures operating in cold climate regions. One of the key parameters determining the
amount of ice accretion is the quantity of incoming sea spray, which eventually comes in contact with the
structure in the presence of brine film freezing temperature. Hence, ...
