The objective of the survey is to better understand the geological characteristics of the wind farm areas by collecting and analyzing geophysical data and developing a ground model to determine the design and installation requirements for the project.
The survey will map all seabed features, including both natural objects like boulders and artificial elements such as wrecks, debris, existing cables, pipelines, and unexploded ordnance (UXO).
The seismic data will be utilized to identify potential shallow geohazards that could impact the placement of wind turbines in the survey area, and to describe the key horizons of the geological formation of the sites.
The collected geophysical data will be used to develop a preliminary ground model, which shall be provided together with the recommendations for the geotechnical program to the separately procured geotechnical survey contractor, who will use it to conduct the geotechnical sampling and testing program.
The results of the geotechnical program, combined with the geophysical data, are said to be used to create an Integrated Ground Model, which will serve as the basis for the design of offshore foundations, structures, and cable burial.
The ELWIND project aims to develop offshore wind sites in Latvian and Estonian territories and establish the fourth electricity interconnection between the two countries.
According to the project’s website, Estonia and Latvia collectively consume about 16 TWh of electricity annually, with ELWIND expected to supply approximately 3 TWh per year.
