A parametric study on the final blade installation process for monopile wind turbines under rough environmental conditions
(Journal article; Peer reviewed, 2018)Single blade installation is a method for installing wind turbine blades. If a jack-up vessel is used during an o shore installation, the wind turbine blade is mainly subjected to wind loads and experiences resonant motions, ... -
Assessment of performance enhancement of a semi-submersible vertical axis wind turbine with an optimized Darrieus rotor
(Journal article; Peer reviewed, 2018)Increasing efforts are currently being devoted to develop floating vertical axis wind turbines (VAWTs), due to their potential to reduce the cost-of-energy. Optimization of rotors is favorable to increase the power capture ... -
Comparative analysis of numerically simulated and experimentally measured motions and sectional forces and moments in a floating wind turbine hull structure subjected to combined wind and wave loads
(Journal article; Peer reviewed, 2018)Multi-body time-domain finite element models, which implement a recently developed numerical approach for determining forces and moments in floaters, are developed to simulate rigid-body motions and sectional forces and ... -
Design of steel bridge girders against ship forecastle collisions
(Journal article; Peer reviewed, 2019)A key aspect in the design of mega bridge structures across navigable waterways is to ensure bridge safety with respect to accidental ship collisions. Special attention has been paid to providing sufficient impact resistance ... -
Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge
(Peer reviewed; Journal article, 2022)Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ... -
Extreme responses and associated uncertainties for a long end-anchored floating bridge
(Peer reviewed; Journal article, 2020)Very-long floating bridges represent an innovative marine structure for crossing wide and deep fjords. During the design of a floating bridge, extreme structural responses at a specified probability of exceedance are ... -
Impact assessment of a wind turbine blade root during an offshore mating process
(Journal article; Peer reviewed, 2019)Single-blade installation is a popular method for installing blades on bottom-fixed offshore wind turbines. A jack-up crane vessel is often employed, and individual blades with their roots equipped with mechanical joints ... -
Numerical and analytical studies of ship deckhouse impact with steel and RC bridge girders
(Peer reviewed; Journal article, 2021)Bridges crossing navigable waterways are under the threat of accidental collisions from passing ships. However, previous research focus was mainly placed on ship collision with bridge substructures while ship-bridge ... -
Prediction of long-term extreme load effects due to wave and wind actions for cable-supported bridges with floating pylons
(Journal article; Peer reviewed, 2018)The characteristic values of the extreme environmental load effects should correspond to a specified annual probability of exceedance. These load effects can be calculated using short-term or long-term methods. The full ... -
Prediction of long-term extreme load effects due to wind for cable-supported bridges using time-domain simulations
(Journal article, 2017)Many long-span bridges that are slender and susceptible to wind-induced vibrations are currently under construction all over the world. As nonlinear structural behavior and nonlinear displacement-dependent wind loads become ... -
Wave load effect analysis of a floating bridge in a fjord considering inhomogeneous wave conditions
(Journal article; Peer reviewed, 2018)When designing a floating bridge crossing a deep and wide fjord, a homogeneous wave field is usually assumed for simplicity. However, waves in fjords are commonly inhomogeneous, and hence the mentioned design practice ...
