Offshore Wind

Site investigations

Based on factors such as the choice of turbine and site conditions, Ramboll will carry out all the necessary analyses to select the foundation type best suited for your offshore wind farm project.

Assessment of met-ocean data

We assess wave and current input data for the structural design. Furthermore, we investigate correlations between waves and wind, which is an important parameter in connection with the design for fatigue. The assessment of wave and current data is also to be used in the numerical modelling of the morphological processes such as erosion and scour.

Geophysical investigations

We specify and perform geophysical investigations and underwater video recordings. These investigations provide input to the archaeological investigations, the environmental impact assessment (EIA) and to the base of the structural design.

Geotechnical investigations

In order to adapt the geotechnical investigations to the specific sites, we specify the investigations in laboratories to suit the individual sites before the investigations are carried out. Furthermore, we carry out and interpret the geotechnical investigations in order to provide a base for the structural design of foundations, turbines and the laying of cables.

Ramboll has been involved in more than 60% of all offshore wind farms

Wind studies

The wind resource, the wind measurements and macro/micro siting of the turbines are assessed. The gathered information is used in relevant software and the project is established. When the energy output has been estimated, the turbine layout can be optimised among other things with regard to requirements from the local authorities.

EIS and EIA

We establish baselines for flora and fauna and estimate the impact on the environment from the wind project leading to environmental impact statements (EIS) or environmental impact assessment (EIA). Visual impact and as well as impact from noise and flicker are examples of issues that are assessed in the EIS. The EIS forms part of the basis on which the local authorities will decide, whether the wind project is to be approved or not.

Navigational risk analyses

For offshore wind farms, we estimate the navigational risk for passing vessels during the construction and during the operational lifetime of the wind farm. The risk analysis provides input to the environmental impact statement, the financial risk analysis and to the base of the structural design.
