The assignment covers the statutory geological supervision of offshore geotechnical site investigation campaigns for offshore wind farms and their connection infrastructure. Campaigns include borehole sampling, down-the-hole and seabed CPTU, seismic CPTU, downhole geophysics (PS logging) and wireline or piggy-back coring, acquiring the ground data that will drive foundation design. The works are executed under a Geological Work Design (GWD) approved by the national authorities; the GWD and national geological regulations take precedence in any dispute, and conformance of the works with the GWD must be formally accepted and signed by a certified geologist holding the appropriate licence category.
Role overview Provide the certified geological authority onboard during offshore geotechnical campaigns: formally accept and sign the conformance of the works with the approved GWD, sign statutory protocols, and support the offshore supervision team on all geological matters, ensuring the works remain compliant with national geological regulations at all times.
Reporting line: to the Project Supervision Manager, with daily reporting to the client's Project and Technical Managers; works alongside the client's offshore geotechnical representatives, the geotechnical contractor's crew and the client's marine management.
Key responsibilities Statutory conformance and sign-off
Accept and sign the conformance of geotechnical works with the approved Geological Work Design, within the scope authorised by the held licence category
Sign protocols on the liquidation of boreholes by cementation, prepared with the offshore supervision team
Advise the supervision team where the GWD or national geological regulations take precedence in operational disputes
Geological oversight of fieldworks
Monitor drilling, sampling and in-situ testing (CPTU, PS logging, coring) for compliance with the GWD, alongside the client's geotechnical representative
Review soil and rock description and the geological content of daily logs and onboard deliverables
Witness tests and sampling operations where formal geological acceptance is required
Preparation and mobilisation
Review project documentation prior to mobilisation: desktop studies, scope of work, technical requirements, the approved GWD, execution plans and HSE documentation
Complete the client's offshore safety induction and attend kick-off meetings, vessel mobilisation and demobilisation at port
Reporting and HSE
Contribute to daily reporting, check-sheets and timesheets, and to the post-campaign supervision report
Report observations, non-conformances and HSE events to the client's project management without delay
Ensure thorough handovers at crew changes, coordinated around port calls
GWD conformance of the geotechnical works formally accepted and signed throughout the campaign
Borehole cementation protocols signed in accordance with statutory requirements
Geological review of daily logs and onboard deliverables completed and documented
Daily reporting contributions and timesheets submitted throughout each campaign
Contribution to the post-campaign supervision report delivered within 10 working days of demobilisation
Required Qualification Requirements Education and licence Must-have:
Qualifications in the profession of geologist for performing, supervising and managing geological works, issued under the Polish Geological and Mining Law of 9 June 2011, in category VI, VII or IX (depending on the seat), or equivalent valid qualifications, including recognition decisions for EU citizens
Licence details (category, number and date of acquisition) available for verification
Experience Must-have:
Relevant experience in offshore or marine geotechnical site investigations (drilling, sampling, in-situ testing)
Practical experience of works governed by an approved Geological Work Design
Nice-to-have:
Offshore wind site investigation campaigns, ideally in the Baltic Sea
Experience as offshore client representative for geotechnical campaigns (the two roles may be combined)
Certifications
Valid offshore survival and offshore medical certificates suitable for Baltic offshore work
Technical skills
Soil and rock description to recognised standards and national practice
Working knowledge of offshore drilling, sampling and CPTU operations
Confident user of the Microsoft Office suite for protocols, logs and reporting
Independent professional judgement: prepared to withhold sign-off until the works conform
Rigorous protocol, documentation and reporting discipline
Comfortable with 12-hour shifts, crew changes and port-call logistics over repeat campaigns
Fluent professional English; Polish is a strong advantage for national geological documentation
