Numerical Investigation of Flow Field Characteristics Around a Monopile Foundation with Collar Protection

open access: yesJournal of Marine Science and Engineering
Collar structures are widely used to protect monopile foundations from scour, but their geometric obstruction hinders direct observation of the surrounding flow in physical experiments.

Accessing offshore wind turbines for maintenance : calculating access probabilities, expected delays and the associated costs using a probabilistic approach [PDF]

open access: yes, 2012
There are ambitious plans in place for the expansion of offshore wind-power capacity in the EU and elsewhere. However, the cost of energy from offshore wind is much higher than that from land-based generation and anything between 15% and 30% of this cost

Analysis of reactive power strategies in HVDC-connected wind power plant clusters [PDF]

open access: yes, 2017
© 2017 John Wiley & Sons, Ltd. Offshore wind power plants (WPPs) built near each other but far from shore usually connect to the main grid by a common high-voltage DC (HVDC) transmission system.

Flow and wakes in large wind farms in complex terrain and offshore [PDF]

open access: yes, 2008
Power losses due to wind turbine wakes are of the order of 10 and 20% of total power output in large wind farms. The focus of this research carried out within the EC funded UPWIND project is wind speed and turbulence modelling for large wind farms ...

Impact of DFIG based offshore wind farms connected through VSC-HVDC link on power system stability [PDF]

open access: yes, 2015
With the increased levels of offshore wind power penetration into power systems, the impact of offshore wind power on stability of power systems require more investigation. In this paper, the effects of a large scale doubly fed induction generator (DFIG)
