Experimental Update of the Overtopping Model Used for the Wave Dragon Wave Energy Converter
Parmeggiani, Stefano; Kofoed, Jens Peter; Friis-Madsen, Erik - In: Energies 6 (2013) 4, pp. 1961-1992
An overtopping model specifically suited for Wave Dragon is needed in order to improve the reliability of its … performance estimates. The model shall be comprehensive of all relevant physical processes that affect overtopping and flexible to … formulation suited for 2D draft-limited, low-crested structures, in order to include the effects on the overtopping flow of the …

A methodology for production and cost assessment of a farm of wave energy converters
Beels, Charlotte; Troch, Peter; Kofoed, Jens Peter; … - In: Renewable Energy 36 (2011) 12, pp. 3402-3416
To generate a substantial amount of power, Wave Energy Converters (WECs) are arranged in several rows or in a ‘farm’. Both the power production and cost of a farm are lay-out dependent.

Experimental Study Related to the Mooring Design for the 1.5 MW Wave Dragon WEC Demonstrator at DanWEC
Parmeggiani, Stefano; Kofoed, Jens Peter; Friis-Madsen, Erik - In: Energies 6 (2013) 4, pp. 1863-1886
The paper presents the results of an experimental study identifying the response of a 1.5 MW Wave Dragon to extreme conditions typical of the DanWEC test center. The best strategies allowing for a reduction in the extreme mooring tension have also been investigated, showing that this is possible...

Computer simulation and field measurement of dynamic pavement loading
Sun, Lu - In: Mathematics and Computers in Simulation (MATCOM) 56 (2001) 3, pp. 297-313
Two methods, i.e. computer simulation and field measurement, are used in this paper to investigate dynamic pavement loading (DPL) generated by vehicle–pavement interaction. A profilometer is used for measuring road surface roughness. Based on the power spectral density of the measured surface...
