Our services included QC supervision of in-situ geotechnical testing and soil sampling. QC supervision was to be conducted "in-field", as per normal RPS activities but the COVID-19 pandemic and associated travel and health concerns made this impossible. Working quickly to keep to the project schedule, RPS in collaboration with our experienced offshore QC specialists designed and implemented a remote QC procedure to address the technical, HSE and communications limitations that were anticipated. Multiple technology and communication platforms were employed to keep the project moving forward.
On completion, RVO's scope of work was fully met, and the data needed to enable a detailed assessment of soil conditions for this wind farm development was acquired, on time.
On March 25th, 2020 at Eemshaven, Netherlands, RVO mobilised Fugro’s geotechnical drilling vessel MV Normand Flower for Lot 1 Phase 2 of the borehole campaign.
The objective of the site investigation was to enhance understanding of the wind farm zone geological features and ground conditions. This was achieved by acquiring appropriate geotechnical data which may be used to progress the design and installation requirements for the offshore wind farm, including, but not limited to foundations and cables.
The site investigation program comprised:
On March 23rd 2020, just two days before planned mobilisation, COVID-19 UK travel restrictions were implemented where HSE became a concern and limited the number of personnel travelling to and joining the vessel. The on-vessel QC role, therefore, needed to be delivered remotely from a secure facility onshore.
With only a few days to modify the project planning, RPS developed a remote QC procedure to address the monitoring, technical, HSE and communications limitations that were anticipated. Our experience in managing similar projects highlighted some critical activities as:
During the project, RPS QC reps needed closer access to monitor the PCPT tests in real-time and using Remote View, which displays the data from the operator screen, were able to verify the tests and data.
By designing a novel and innovative solution to deliver geotechnical and HSE QC services remotely, RPS was able to meet RVO's technical requirements within the required timeframe.
The vessel arrived back in Eemshaven on June 17th, 2020 after delivering a total of 58 boreholes. Sufficient data was acquired to enable a detailed assessment of soil conditions for the progression of the Netherlands Government tendering process and conceptual foundation engineering.
