Statistical Modeling and Applications of Joint Distributions for Significant Wave Height, Spectral Peak Period, and Peak Direction of Propagation: A Case Study in the Norwegian Sea
(Peer reviewed; Journal article, 2023)The estimation of long-term extreme response is a crucial task in the design of marine structures. The target extreme responses are typically defined by annual exceedance probabilities of 10-2 and 10-4. Various approaches ... -
Metocean conditions at two Norwegian sites for development of offshore wind farms
(Peer reviewed; Journal article, 2024)This paper examines metocean data from NORA3, a state-of-the-art wind and wave hindcast dataset for Northern Europe. Two offshore Norwegian areas, Utsira Nord (UN) and Sørlige Nordsjø II (SN2), are investigated. Both areas ... -
An approach for optimization of controllable drilling parameters for motorized bottom hole assembly in a specific formation
(Peer reviewed; Journal article, 2023)This study focuses on optimizing drilling parameters when using Positive Displacement Motors (PDMs). In drilling operations involving mud motors, weight-on-bit (WOB) alterations lead to variations in the system's parasitic ... -
The challenges experts face during creeping crises: the curse of complacency
(Peer reviewed; Journal article, 2024)The policy literature has generally conceptualised crises as urgent public threats with clearly demarcated ‘focusing events’. Consequently, most studies have identified the main challenges faced by expert agencies involved ... -
New tests for trend in time censored recurrent event data
(Peer reviewed; Journal article, 2024)We consider testing for trend in recurrent event data. More precisely, for such data we consider testing of the null hypothesis of data coming from a renewal process. The new tests are essentially obtained by considering ... -
Challenges associated with mercury occurrence on the Norwegian Continental Shelf
(Master thesis, 2023)The thesis includes a review of the heavy metal mercury, with focus on its origin, effect on the environment, and its role in the petroleum industry. Mercury emissions from the petroleum industry in Norway is looked into ... -
Pulsar timing array stochastic background from light Kaluza-Klein resonances
(Peer reviewed; Journal article, 2023-11)We investigate the potential of the warped extradimension framework as an explanation for the recently observed stochastic gravitational background at nHz frequencies in pulsar timing arrays (PTA). Our analysis reveals ... -
Transitioning towards renewable energy and sustainable storage solutions at remote communities in the Arctic, Case study of Flatey, Iceland
(Peer reviewed; Journal article, 2023)The need for transitioning towards renwable energy and sustainable storage solutions is particularly challenging for remote communities in the Arctic, located far away from the electricity grid. This paper explores the ... -
