Geodynamic and Structural
ISAMGEO offers geodynamic and Structural Health Monitoring (SHM) solutions for the detection of pre-failure conditions of critical infrastructure in seismic areas.
Characterization and modeling of the structure are used to design of a tailored monitoring system.
Monitoring includes ambient noise analysis to differentiate between background noise and relevant signals site-specific.
For each system, customized alerting and operational responses are proposed and implemented to meet client needs and project-specific requirements.
Application areas: bridges, refineries, offshore platforms, pipelines, dams, metro lines, windfarms and mines
Ambient Noise Analysis uses background noise to identify various frequencies and vibrations without requiring external excitation, for continuous monitoring in sensitive or hard-to-access locations.
Operational Modal Analysis (OMA) using a Frequency Domain Decomposition (FDD) algorithm identifies the dynamic properties of structures under actual operating conditions. It relies only on ambient vibrations and is applicable to large structures in any industrial context.
Finite element modeling (FEM) simulates the dynamics of a structure by incorporating its design and expected material properties. This approach enables engineers to predict how the structure responds under changing loading conditions.
Push-over analysis is applied to identify which structural elements are most vulnerable during a severe earthquake.
For complex structures like offshore platforms and wind farms, ISAMGEO offers integrated meteo-marine monitoring solutions to track structural aging caused by combined weather conditions and seismic activity.
For remote locations with limited connectivity, ISAMGEO provides iridium-based solutions to ensure reliable data transmission between field and monitoring location.
