Fugro has mobilized and conducted a traditional geotechnical site investigation. Such work is currently ongoing for the Oriel offshore wind farm, located off the coast of County Louth, Ireland. This imaginative project lays the groundwork for Ireland’s renewable energy ambitions. It has utilized the power of the wind to deliver renewable energy to an estimated 300,000 residences.
Now the Oriel offshore wind farm will only span 24 kilometers squared. As such, it is slated to host 25 of the wind turbines, which are expected to produce a cumulative capacity of 375 megawatts (MW). Fugro has already begun the unique collection of critical data to support the investigation. This invaluable information will help guide the design and installation of the delicate oceanic wind farm foundations.
Fugro Danaos carries out a large variety of survey types. Their work involves high-resolution cone penetration testing and wireline geophysics in water depths up to 33 m. The Fugro Voyager is deployed with advanced equipment, such as the SEADEVIL coring system, to obtain crucial soil samples from the offshore environment.
Fugro performs lab analysis at its Wallingford facility. Above all, their aim is to make sure the data they collect moves the project—and the artist’s vision—forward. Specific technical challenges posed by the Irish Sea location require early access to high-quality geo-data. This information is essential for determining best practices for designing and installing foundations to support cast pipes.
Remmelt de Jong, another main driver behind the collaborative project, explained just how important the data collection process is.
“Partnering with Fugro on this geotechnical survey campaign represents an important milestone, enabling us to progress our detailed project design and bringing us closer to realizing the Oriel project and contributing to Ireland’s offshore wind ambitions.”
The Oriel offshore wind farm is being advanced in partnership by JERA Nex and ESB. Overall, this initiative represents a significant step forward in expanding the use of renewable energy resources in Ireland and responding to demands for greater environmental sustainability. This large-scale geotechnical survey has now been successfully wrapped up! Today, stakeholders are committed to taking further steps to seize the tremendous opportunities that come with developing offshore wind energy potential in the region.
“Early access to high-quality geo-data is critical for projects of this scale. By understanding the site’s ground profile, Oriel Windfarm can make informed decisions that support the long-term performance of offshore wind assets.”
The Oriel offshore wind farm is being developed collaboratively by JERA Nex and ESB. The initiative reflects a commitment to advancing renewable energy resources in Ireland while addressing environmental sustainability concerns. With the successful completion of this geotechnical survey, stakeholders expect to make significant progress toward realizing the potential of offshore wind energy in the region.
