Geotechnical & Geophysical (G&G) Manager

Key Responsibilities

• Lead desktop feasibility studies to identify geohazards and ground conditions (UXO, boulders, shallow gas, faults) and inform early design and risk strategies.
• Define and execute the G&G campaign strategy, including phased geophysical, UXO, and geotechnical investigations aligned with permitting, certification, and design schedules.
• Establish commercial and risk-allocation strategies for ground risk between developer and contractors, including ALARP demonstration.
• Own the planning, scheduling, and delivery of geophysical and geotechnical survey campaigns, ensuring alignment with seasonality, permitting, and overall project milestones.
• Lead procurement and contract management for survey contractors and consultants, including scope definition, bid evaluation, negotiations, VO management, payments, and claims.
• Set and enforce data standards, QA/QC, and HSE requirements, reviewing RAMS and ERPs and managing client representatives and survey managers offshore.
• Manage data interpretation and geotechnical engineering studies, including laboratory testing strategies, GIRs, Geotechnical Design Basis, and advanced analyses (e.g. IGM, PSHA, SSRA, seabed mobility).
• Coordinate seamless data integration and handover across survey contractors, engineering consultants, and design packages (foundations, cables, T&I).
• Provide technical leadership during construction, managing geotechnical risks, UXO clearance strategies, as-built ground records, and supporting dispute or claims resolution.
• Lead technical engagement with certification bodies, ensuring geotechnical deliverables meet project, regulatory, and certification requirements.

Experience & Skills

• Master’s or PhD in Civil/Geotechnical Engineering, Engineering Geology, Geophysics, or a related quantitative discipline.
• Minimum 10 years of offshore marine geotechnics/geophysics experience, with hands-on involvement from pre-FEED through construction, including site investigations, laboratory testing, and reporting.
• Deep practical knowledge of offshore installation and foundation concepts, including pile drivability, leg penetration and damping, cable trenching, burial, and protection methodologies.
• Extensive experience in survey procurement and execution, deliverables QA/QC, and translating geotechnical and geophysical data into foundation and cable design inputs.
• Proven ability to manage geotechnical ground models, assess soil conditions, and evaluate installation and construction risks.
• Strong working knowledge of geotechnical software tools (e.g. PLAXIS 3D, GRLWEAP or similar) and programming capabilities (MATLAB and/or Python preferred).
• Demonstrated project management and leadership capability, including coordination of consultants, subcontractors, and multi-stakeholder interfaces (formal certification advantageous).
• Solid commercial and contractual acumen, bridging technical requirements with business needs and engaging effectively with geoscience suppliers and contractors.
• Strong commitment to HSE and environmental best practices, with a working knowledge of relevant regulations, safety standards, and quality systems.
• Excellent communication, reporting, and interpersonal skills, able to work independently or within multidisciplinary teams, fluent in written and spoken English, and driven by continuous improvement.
