Abstract
ELSAM is planning an offshore 150 MW wind power plant at Horns Rev, which is to be in operation by the end of 2003. The project is part of the Danish governmental environment and energy objective and is to act as a role model for future power plants at sea. The go-ahead for the project was obtained in the summer of 1999. This report is written at the request of ELSAMPROJEKT, according to the proposal: 'Tilbud pae VVM undersoegelse af hydrografi for havvindmoellepark ved Horns Rev'. Establishing a wind power plant at Horns Rev 15 km offshore Blaevands Huk has a potential impact on local hydrography and thus potentially on local and regional coastal morphology. In order to assess these topics, investigations of the impact of the foundations on currents and waves have been carried out locally in the area where the wind power plant is to be erected area as well as in the nearby region. Furthermore, in connection with establishing the single foundations, sediment spill may influence the water quality in sensitive areas and spill simulations have thus been carried out. This investigation is to be part of an overall EIA of the setting up of the wind power plant at Horns Rev, describing the consequences of establishing and running the power plant. In order to meet the requirements of the statute concerning impact on the environment, the following aspects will be addressed in this document: 1) hydrography. 2) coastal morphology. 3) sediment transport.
