Application of Morison equation in irregular wave trains with high frequency waves
(American Society of Mechanical Engineers (ASME), 2018)
Conference report
Restricted access - publisher's policyMost numerical models for the analysis of offshore wind platforms are based on one of two different approaches, depending on how waves forces are applied to the structure: 1) the potential flow theory, and 2) the Morison ... -
Application of over-current relay in offshore wind power plant grid with VSC-HVDC connection
(2011)
Conference report
Restricted access - publisher's policyThis paper presents the setting and coordination of over-current relays in an offshore wind power plant (WPP) grid connected only to the power electronic converters with limited fault current capability. The limited fault ... -
Autonomous inertia-sharing control of multi-terminal VSC-HVDC grids

Damage detection and diagnosis for offshore wind foundations
(2020)
Conference report
Restricted access - publisher's policyStructural health monitoring for wind turbines (WT) in remote locations, as offshore, is crucial (Presencia and Shafiee, 2018). Offshore wind farms are increasingly realized in water depths beyond 30 meters, where lattice ... -
Damage diagnosis for offshore wind turbine foundations based on the fractal dimension
(2020-10-05)
Article
Open AccessCost-competitiveness of offshore wind depends heavily in its capacity to switch preventive maintenance to condition-based maintenance. That is, to monitor the actual condition of the wind turbine (WT) to decide when and ... -
Decommissioning of offshore wind turbines
(Universitat Politècnica de Catalunya, 2019-02-19)
Bachelor thesis
Open AccessDecommissioning is a key process in the offshore wind industry because all substructures, bottom fixed or floating, have to be removed and completely dismantled at the end of their service life. There is still no experience ... -
Design optimization for a truncated catenary mooring system for scale model tests
(2014)
Conference report
Restricted access - publisher's policyOne of the main aspects when testing floating offshore platforms is the scaled mooring system, particularly with the increased depths where such platforms are intended. When the existing testing facilities do not have ... -
