Wave Influenced Wind and the Effect on Offshore Wind Turbine Performance
(Journal article; Peer reviewed, 2014)In this paper the effect of wave influenced wind on offshore wind turbines is studied numerically. The wave is seen as a dynamical roughness that influences the wind flow and hence the wind turbine performance. An actuator ... -
Weather sensitivity of maritime activities on Chinese Shelf
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013-10-03)The objective of the thesis is to discuss the weather sensitivity of maritime activities, inter alia, with respect to the aspects of passage planning, load plan-making, and ship maneuvering. As maritime activities represent ... -
Welding procedure qualification record (WPQR) for welds fabricated at proximity
(Peer reviewed; Journal article, 2022)Maintaining the minimum allowable distance between proximity welds has always been considered a subject of debate among design engineers, welding engineers/inspectors and fabricators/engineering contractors. The scattered ... -
Will Europe achieve its Offshore Floating Wind energetic targets for 2050?
(Master thesis, 2023)The objective of this master's thesis is to investigate the feasibility of assembling and installing the expected capacity of offshore wind farms. The focus of the study will be solely on the installation of Offshore ... -
Wind and Vibration Measurements on the Lysefjord Bridge
(Master thesis, 2022)The Lysefjord Bridge is a suspension bridge located in the western part of Norway. Since 2013 it has been used as a full-scale wind engineering laboratory and is fitted with sonic anemometers, tri-axial accelerometers, ... -
Wind coherence measurement by a single pulsed Doppler wind lidar
(Journal article; Peer reviewed, 2016)A single pulsed Doppler wind lidar, deployed at the FINO1 platform in the North Sea, has been used to monitor the lateral and vertical coherence of the along-wind component. To maximize the sampling frequency of the ... -
Wind Fatigue Analysis - Evaluation of Different Methods and Software Alternatives
(Master thesis, 2022)Wind induced fatigue damage affects most slender structures such as flare booms and bridges in offshore environment. Due to the irregular and dynamic nature of wind, wind loading might cause structures to vibrate near the ... -

Wind Flow Simulation over Fish Farm Feed Barge
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06-15)There are approximate over 1000 fish farms in Norway, where half are connected to the grid and the rest are driven by diesel generators. Fish farms use large air compressors to feed the fish, which creates high power ... -
Wind Profile Usage in Wind Farm Installation Campaign Simulations
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-15)Simulation tools are used in the wind industry to analyse and understand installation campaigns for strategic planning purposes. These tools use vertical wind profiles to estimate wind speeds at various heights. Where these ... -
Wind resource analyses at Westermost Rough Wind Farm
(Master thesis, 2023)A transition towards renewable energy sources is a pressing concern for society and government officials, and the offshore wind industry is more relevant than ever. The industry has the potential to meet Europe’s energy ... -
Wind tunnel CFD simulation by using OpenFOAM
