Choice of fuel system for the offshore support fleet
(Journal article; Peer reviewed, 2019)The stringent requirements of the IMO's emission regulations call for alternative fuels and new ways of powering ships. However, the IMO predicts that technology which could reduce ship emission to zero, will either not ... -
The classification and reutilisation of recycled asphalt pavement binder: Norwegian case study
(Peer reviewed; Journal article, 2022)With increased demand of asphalt pavement and limited binder and aggregate supply, the reutilisation of Recycled Asphalt Pavement (RAP) has gained more attention in pavement engineering from the environmental, sustainable, ... -
Coastal Erosion Due to Decreased Ice Coverage, Associated Increased Wave Action, and Permafrost Melting
(Chapter, 2018-11)It is broadly recognized that the Arctic area has become highly popular for hosting new activities and new infrastructure. This is due to the combination of the need of exploring new areas to satisfy the ever increased ... -
Combining Computational Fluid Dynamics and Gradient Boosting Regressor for Predicting Force Distribution on Horizontal Axis Wind Turbin
(Journal article, 2021)The blades of the horizontal axis wind turbine (HAWT) are generally subjected to significant forces resulting from the flow field around the blade. These forces are the main contributor of the flow-induced vibrations that ... -
Compaction and Fluid—Rock Interaction in Chalk Insight from Modelling and Data at Pore-, Core-, and Field-Scale
(Peer reviewed; Journal article, 2020)Water weakening is a phenomenon that is observed in high porosity chalk formations. The rock interacts with ions in injected water and additional deformation occurs. This important effect needs to be taken into account ... -
Comparative analysis of artificial neural network model and analysis of variance for predicting defect formation in plastic injection moulding processes
(Peer reviewed; Journal article, 2023)This study investigates the impact of plastic injection moulding process parameters on overflow defect formation. Experiments were conducted using a Taguchi L27 orthogonal array design. Multilayer Perceptron (MLP) artificial ... -
Comparative dynamic analysis of two-rotor wind turbine on spar-type, semi-submersible, and tension-leg floating platforms
(Peer reviewed; Journal article, 2022)Multi-rotor floating offshore wind turbines have been recently proposed as an innovative technology to further reduce the cost of offshore wind energy. Even though examples of commercial prototypes are present, the literature ... -
Comparative study of circular and square gravity-based fish cages with different dimensions under pure current conditions
(Peer reviewed; Journal article, 2021-12)Two typical gravity-based fish cages with circular and square shapes are modeled in the present study to compare their cage deformations, cultivation volumes and drag forces under different pure current conditions. Two hy ... -
Comparative study of five commonly used gravity type fish cages under pure current conditions
(Peer reviewed; Journal article, 2022-04)Gravity type fish cages have been commonly used in marine aquaculture for years. However, only limited research efforts have been made to assess the influences of different design parameters on the structural responses of ... -
Comparative study of indirect tensile test and uniaxial compression test on asphalt mixtures: Dynamic modulus and stress-strain state
(Peer reviewed; Journal article, 2022)Dynamic modulus is an essential parameter for the performance characterisation of asphalt materials for performance prediction and pavement design. The Indirect Tensile (IDT) test and the Uniaxial Compression (UC) test are ... -
Comparative study on loosening of anti-loosening bolt and standard bolt system
(Peer reviewed; Journal article, 2022)In general, bolted connections are exposed to vibrations or repeated over-loads that could lead to self-loosening due to loss of preload. Pre-tensioned bolts in ring flanges are critical parts in Offshore Floating Wind ... -
Comparing different CFD wind turbine modelling approaches with wind tunnel measurements
(Peer reviewed; Journal article, 2014)The performance of a model wind turbine is simulated with three different CFD methods: actuator disk, actuator line and a fully resolved rotor. The simulations are compared with each other and with measurements from a wind ... -
Comparison of unidirectional and bidirectional airfoils in a tidal stream turbine
(Peer reviewed; Journal article, 2022)Tidal stream turbines offer an attractive method for stable renewable energy generation. Due to the periodicity of the tidal stream, a tidal stream turbine can be designed to operate in a bidirectional manner, thereby ... -
A comparison study of power performance and extreme load effects of large 10-MW offshore wind turbines
(Peer reviewed; Journal article, 2023)The utilisation of offshore wind turbines has rapidly increased in the last decade, which has resulted in a steady increase in wind turbine sizes. The global average offshore wind turbine size has increased from 1.5 MW to ... -
A compensation scheme applied on wind turbine blade pitch control for the reduction of non-torque main shaft loads
(Peer reviewed; Journal article, 2021)It has been well established that non-torque main shaft loads influence the internal drive train loads. This paper proposes a scheme that compensates for non-torque loads in the blade pitch controller. The compensation ... -
