Twelve specialised vessels are beginning the main phase of geotechnical surveys of the
Completion of the tests is scheduled for later this year. The results will provide a basis for the development of a detailed plan of locations of the foundations for the turbines and offshore substations and their connection to the onshore transmission infrastructure.
'We want to start construction of the offshore wind farm as early as in 2023. It is a pioneering venture that will not only transform the Polish power system, but will also allow us to gain new capabilities in the area of large-scale zero-emission projects. Geotechnical surveying is an extremely complex process, involving dozens of high-level professionals and high-tech equipment. Once it is completed, we will be able to develop a detailed technical design that will be optimal for the project's schedule and economics,' said
On the basis of the data collected during the drilling and sounding, and its subsequent analysis, designers will prepare documents such as the final plan showing location of the wind turbines, their support structures, and the farm site and power export cables route. The farm seabed tests are being performed for
Construction of an offshore wind farm is a complex project, which requires multi-step control of the preparation processes and verification of the design assumptions. One of the key tools to avoid risks is the project certification procedure. The Company entrusted this task to an experienced Norwegian company, DNV, which is involved in this type of services in about 80% of all offshore wind farm projects worldwide. Under the contract signed with
The geotechnical tests on the farm site and along the cable connection route have been preceded by the start of UXO detection surveys, performed to search for any unexploded ordnance at sea. During the preliminary geophysical surveys carried out in 2019 for the purposes of an environmental report, dozens of objects that may pose a threat in the offshore construction phase were detected on the farm site. They included fragments of shipwrecks, rock formations, and remnants from World War II, such as a torpedo and probably a sea mine. A more extensive UXO survey will make it possible to verify the data already acquired and possibly identify other elements that may pose a risk on the offshore construction site.
