DANWEC will enable wave energy developers located at Hanstholm to share resources, in order to encrease the rate of development of their devices while reducing costs. Hanstholm is located on the north west coast of Denmark; the location of the buoy is shown in figur 1. The website that this document describes will allow developers to access the processed data from the buoy located near Hanstholm, data from the weather station at Hanstholm harbour and the water level in the harbour. As wave energy devices are dependent on the sea condition, the wave parameters are necessary for characterizing the device, in order to determine its performance in situ and at other locations and scales

Kofoed                    June 2012          © Aalborg University         Aalborg University Department of Civil Engineering Wave Energy Research Group       Scientific Publications at the Department of Civil Engineering  Technical Reports are published for timely dissemination of research results and scientific work carried out at the Department of Civil Engineering (DCE) at Aalborg University. This medium allows publication of more detailed explanations and results than typically allowed in scientific journals.  Technical Memoranda are produced to enable the preliminary dissemination of scientific work by the personnel of the DCE where such release is deemed to be appropriate. Documents of this kind may be incomplete or temporary versions of papers—or part of continuing work. This should be kept in mind when references are given to publications of this kind.  Contract Reports are produced to report scientific work carried out under contract. Publications of this kind contain confidential matter and are reserved for the sponsors and the DCE. Therefore, Contract Reports are generally not available for public circulation.  Lecture Notes contain material produced by the lecturers at the DCE for educational purposes. This may be scientific notes, lecture books, example problems or manuals for laboratory work, or computer programs developed at the DCE.  Theses are monograms or collections of papers published to report the scientific work carried out at the DCE to obtain a degree as either PhD or Doctor of Technology. The thesis is publicly available after the defence of the degree.  Latest News is published to enable rapid communication of information about scientific work carried out at the DCE. This includes the status of research projects, developments in the laboratories, information about collaborative work and recent research results.
