3D Geophysical Ultra High Resolution Survey (UHRS) Report

This link gives access to report that is part of a Pilot of a 3D UHRS Data set acquired at the Ten noorden van de Waddeneilanden (TNW).RVO has commissioned a 3D Ultra High Resolution Seismic (UHRS) survey over a subsection of the Ten noorden van de Waddeneilanden (TNW) survey area in order to investigate the potential for benefit of this kind of information to the ground model for an offshore wind development at the site. The report gives more details on operation events and parameters for the survey performed, together with a Preliminary Assessment of Potential Geohazards that have been observed in the 3D UHRS data. At the moment of publishing this report no structured interpretation has been done on the data set yet.

The 3D UHRS data can be obtained by requesting the data via the orderform in this same widget. A HDD will be received containing the 3D UHRS data set together with the data/results for the standard geophysical data set the Ten noorden van de Waddeneilanden (TNW) area.

The 3D UHRS data section covers structure at a range of scale, from small scale features associated with the Holocene sand cover and shallow channels, to deeper structures at a range of scales associated with the sequence of glaciations that have influenced the site. The data have been acquired using instrumentation designed to return vertical resolution of 1 m or better, at a trace spacing of 1 m at the maximum required depth of interest of 60 m.

RVO encourages all users of this Pilot of the 3D UHRS Data to share their view of the acquired data and their experiences with the application of this data. For RVO it is of utmost importance to understand the end-users needs and concerns in order to be able to address them in the upcoming WFZ pre-developments. Your feedback will enable RVO to set the right priorities in the soil investigations and the evaluations and reporting of the results.

 

This means that RVO is interested in receiving feedback from potential licensees on the value of these data, in particular:

  • Will this kind of data improve confidence in costing cable infrastructure?
  • Will this kind of data improve confidence in costing foundation infrastructure?
  • Will this kind of data provide a reduction in time-to-first-energy-generation?
  • In order to provide benefit, would this kind of data be required site-wide?
  • If site-wide acquisition was cost-prohibitive, would a lattice arrangement work, within which a layout could be planned?
  • Could developers use these data to reduce the volume of intrusive site investigation work?
  • Could these data be used post-award in design, and if so, how would they need to be qualified?
  • Is the vertical and lateral resolution specified appropriate, could a lower resolution dataset still provide value?
  • What kind of analysis and reporting product is required to support 3D UHRS data, and what, if added, would represent real added value?
