Benefit from our unique, leading-edge seismic data processing and 3D interpretation workflow imagisTM.
Hydrographic and geophysical surveys are routinely carried out prior to completion of the initial geological ground model for prospective offshore wind farm sites. Both datasets have the potential to contribute valuable information to your understanding of the site. The accuracy and reliability of the hydrographic and geophysical surveys undertaken are critical so that turbine foundations can be located and designed in the most appropriate and cost-effective way.
A high standard of hydrographic data is common, and the expected outputs well defined. However, the quality of geophysical surveys varies greatly, with no agreed industry standard for the type and quality of reporting or data deliverables. Surveys for large offshore wind farm projects can produce Terabytes of high-quality seismic data, but if these data are not properly managed, processed, interpreted, and reported these data are essentially useless to you.
Proper specification of a geophysical survey can make the difference between you receiving blurry low-resolution seismic sections and having a digital database of georeferenced key interface elevation surfaces ready for inclusion in your modelling and visualisation software. Failure to ensure that surveys are properly specified at the outset has led and will lead wind farm developers to spend substantial amounts of additional money on resolving issues that could easily have been avoided.
Depending on your needs and the maturity of your project, we can provide services at any level from legacy data audits to full specifications, tender evaluation, Client Representative support (onshore), geophysical data processing, analysis, and interpretation, and 3D geological Ground Model development.
Our staff have been involved in near-surface geophysical consultancy for over 25 years and we are regarded as the leading independent environmental and engineering geophysical consultancy in the UK and have an international reputation. RIL staff publish regularly in international, peer-reviewed journals. By having a thorough understanding of the range of inter-disciplinary techniques used in ground investigation, we are well placed to advise on how geophysical surveys can complement traditional investigation methods so that you can obtain the best outcomes from your surveys.
We also offer a CPD-accredited, one-day, corporate facilitated workshop, titled ‘High-resolution Marine Geophysical Investigation for Offshore Structures’. This unique course is essential for anyone working on offshore wind farm developments in a project management, technical engineering, or geotechnical capacity. For more information, see the marine geophysical workshop webpage.
Reynolds International Ltd (RIL) staff have been providing project management and operational support services for high-resolution, over-water site investigation projects for over 25 years. We have developed substantial expertise in this area so you can be confident that we have the skills and resources necessary for your project.
Marine Geophysical Workshop
RIL have developed a one-day corporate workshop titled ‘High-resolution Marine Geophysical Investigations for Offshore Structures’. This unique course is essential for anyone working on offshore wind farm developments in a project management, […]
Many offshore wind farm developers have already completed geophysical and hydrographic surveys in the early stages of project development or acquired a project from others. The specifications for these surveys may not have been as […]
Specification and Tender Evaluation
It is important that surveys are properly specified so that they yield the information you want, not just what a geophysical contractor wants to give you. Through strict specifications you can ensure that your surveys yield the best data quality and […]
Client Representative Support and Report Evaluation
A key element for Clients is having a suitably qualified and experienced ‘Client Representative’ on board the survey vessel making sure that the best quality hydrographic and geophysical data are collected as per the specification. […]
Processing, Interpretation and 3D Geological Ground Model Production
Offshore wind farm geophysical surveying has only recently begun to catch up with geophysical processing and interpretation standards […]
