Description

Project scope

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

Key deliverables

• 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
