At EPI, we deliver a comprehensive suite of geotechnical site investigation services supporting the full lifecycle of offshore energy projects across the renewables, oil and gas, and submarine cable sectors. Our in-house team of geotechnical specialists manage every phase of the project, from early-stage planning and design to acquisition oversight and final reporting, ensuring technical excellence and alignment with client objectives.
We develop detailed scopes of work, project execution plans, and technical specifications, all grounded in industry best practices. Our services include preparing and evaluating invitations to tender, assessing survey contractors, conducting vessel suitability audits, and supervising mobilisations to ensure operational readiness and safety.
During acquisition, EPI provides expert oversight and quality assurance across all geotechnical operations. This includes managing sampling campaigns using piston corers, cone penetration testing systems (CPT and CPTu), vibrocorers, box corers, grab samplers and other in-situ tools. We provide experienced and trusted offshore client representatives, these specialists monitor acquisition parameters in real time using industry-leading software platforms, ensuring data integrity and compliance with regulatory and client standards.
Beyond field operations, we maintain continuous communication and reporting throughout the project lifecycle. Using our proprietary EPIQC™ system, we manage daily, weekly, and monthly reporting, facilitate coordination meetings, and provide technical advisory support. We also oversee data interpretation, final report preparation and Geotechnical Interpretive Reports (GIR), ensuring deliverables are comprehensive, accurate, and aligned with the defined quality assurance framework, maintaining compliance with DNV, ISO and IMCA standards.
