Seismic Expertise for Offshore Energy
Advanced Seismic and Geotechnical Assessment for Offshore Infrastructure
Independent engineering expertise supporting the design, evaluation and life extension of offshore oil and gas facilities and subsea infrastructure.
Specialist Offshore Engineering Capabilities
AD Consulting provides specialised seismic and geotechnical engineering expertise for offshore energy infrastructure. Our capabilities cover the assessment of earthquake ground motions, seabed response and permanent ground deformation, supporting the design, evaluation and continued safe operation of offshore facilities.
Offshore Probabilistic Seismic Hazard Assessment
Site-specific Probabilistic Seismic Hazard Assessments (PSHA) for offshore platforms and subsea infrastructure. ADC evaluates regional and local seismicity, seismotectonic characteristics, earthquake source models and appropriate ground-motion models to establish reliable seismic design parameters for offshore engineering applications.
Seabed Site Response Analysis
Evaluation of seismic wave propagation through seabed soil profiles, accounting for local geological and geotechnical conditions. ADC assesses the influence of soil layering and dynamic soil properties on earthquake-induced ground motions and develops site-specific seismic input parameters for offshore structural and geotechnical engineering.
Soil Liquefaction Assessment
Assessment of the susceptibility of seabed soils to earthquake-induced liquefaction and associated ground deformation. ADC evaluates relevant soil characteristics and seismic loading conditions to identify potential effects on offshore foundations, pipelines and subsea installations.

Fault Displacement Hazard Assessment (FDHA)
Assessment of earthquake-induced fault displacement and permanent seabed deformation affecting offshore infrastructure. ADC evaluates the potential for surface fault rupture, displacement magnitude and spatial distribution, considering the characteristics of active faults and their relationship to offshore facilities, foundations and subsea pipelines. These assessments provide essential input for the evaluation of fault-related ground deformation hazards and engineering design.
Seismic Support for Offshore Asset Life Extension
Specialist seismic engineering support for the continued safe operation and life extension of existing offshore installations. ADC provides focused assessments of seismic hazard and relevant seabed-related geohazards, helping operators evaluate the implications of updated technical requirements and the condition of ageing offshore assets.
Our expertise supports the reassessment of existing facilities, identification of seismic vulnerabilities and development of appropriate engineering recommendations for extended operational service.
