Machine learning forecasts of Scandinavian numerical weather prediction wind model residuals with control theory for wind energy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-22)The quality of wind data from the numerical weather prediction significantly influences the accuracy of wind power forecasting systems for wind parks. Therefore, an in-depth investigation of these wind data themselves is essential to improve wind power generation efficiency and maintain grid reliability. This paper proposes a novel framework based on machine learning for concurrently analyzing and ... -

Marine Icing and Anti/De-icing Systems
(Conference object; Konferansebidrag, 2015-12-10)Shipping operations are on the rise in the Arctic region. Due to these increased activities, maritime transport operations are encountering significant challenges with respect to the safety and reliability. These shipping operations are comprised of commercial vessels such as oil tankers, container ships, fishing vessels, tourism cruises, research and offshore exploration vessels and icebreakers In ... -
Marine icing observed on KV Nordkapp during a cold air outbreak with a developing polar low in the Barents sea.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06)Marine icing is a phenomenon that may occur for temperatures below subfreezing where sea spray either is lofted from the sea surface or being generated by waves interacting with a ship or a structure. On a voyage from Tromsø to the waters east of Bjørnøya late February 1987, the Norwegian Coast Guard vessel KV Nordkapp experienced heavy icing due to a polar low that raged over these waters during ... -
Marine Operations in Arctic conditions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023)Marine operations require careful early planning and thereafter detailed planning prior to project execution. The time from initiating an operation to finalization of the activity is typically several days. The activity can only be conducted during limited weather conditions. The planning prior to the offshore operations does, therefore, require accurate weather forecasting. The weather conditions ... -

Maritime safety and the ISM code: a study of investigated casualties and incidents
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-08-27)Abstract In 1993, the International Maritime Organization adopted the International Safety Management (ISM) Code which requires all shipping companies operating certain types of vessels to establish safety management systems. Nevertheless, two decades later, maritime safety remains a concern. This article studies 94 maritime cases investigated by the Maritime Accident Investigation Branch in the ... -
Maritime Security and Threat Assessments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12)Maritime security is still a challenge in international trade. In this case‐study we analyze how the Norwegian Shipowners’ Mutual War Risks Insurance Association (DNK) provides Norwegian maritime companies with regional assessments of threat‐levels. Through a survey and a series of interviews, we study factors that affect the communication and perception of threats, in addition to how maritime ... -

Measuring the Sea Spray Flux using High-Speed Camera
(Conference object; Konferansebidrag, 2015-12-10)The sea spray contains water droplets that are produced due to sea waves that collide with the marine structures as well as the breaking of waves due to the strong winds. Similarly, fog and precipitation at sea level may contribute to the phenomenon of sea spray containing water droplets of minuscule sizes. Wind characteristics (speed and direction) also has a direct influence on the speed of water ... -
A Methodological Framework for the Resilience Analysis of Road Transport Networks Exposed to Freezing Rain
(Conference object; Konferansebidrag, 2022)Road transport network is one of the major critical infrastructures to be maintained resilient, since its disruption would not only have direct economic consequences, but it could also lead to domino effects on other critical infrastructures. This study proposes a methodological framework for the analysis of the resilience of road transport networks exposed to natural hazards, in particular to ... -
A methodology for collecting donning times of thermal protective immersion suits intended to be worn by passengers on vessels operating in cold environments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021)Adequate thermal protection for passengers travelling on-board vessels in cold climate regions, such as that provided by thermal protective immersion suits (TPIS), enhances passenger survivability in emergency situations, in particular those requiring the abandonment of the vessel. As emergency abandonment is a time critical process, it is essential to consider the time required to correctly don the ... -
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 ... -
A mixture frailty model for maintainability analysis of mechanical components: a case study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-07)Knowing the maintainability of a component or a system means that repair resource allocations, such as spare part procurement and maintenance training, can be planned and optimized more effectively. Repair data are often collected from multiple and distributed units in different operational conditions, which can introduce heterogeneity into the data. Part of such heterogeneity can be explained and ... -
Modelling the transport of oil after a proposed oil spill accident in Barents Sea and its environmental impact on Alke species
(Konferansebidrag; Conference object, 2017)Accidental oil spills can have significant effect on the coastal and marine environment. As the oil extraction and exploration activities increase in the Barents Sea, it is of increasingly importance to investigate the potential oil spill incidents associated with these activities. In this study, the transport and fate of oil after a proposed oil spill incident in Barents Sea was modelled by oil ... -
Modern Army for Modern Times or Private Paramilitary? Polish Territorial Defense Force as a Benchmark Case in Conflict Evolution
(Journal article; Tidsskriftartikkel, 2023)The new Polish military branch, the Territorial Defense Force (TDF), has been described both as a defensive tool against Russian hybrid warfare and as a private paramilitary force of the incumbent Law and Justice Party. This paper examines the strategic, political, and military purposes of the Territorial Defense Force using two theoretical models. One is designed for analyzing units intended to ... -
