This means the updated standard places a heavier emphasis on:
: Represents a severe, rare seismic event. The structural objective shifts from damage prevention to collapse prevention . The platform must demonstrate sufficient structural ductility to absorb extreme energy loads without experiencing structural failure. 2. Site-Specific Hazard Analysis api rp 2eq pdf updated
: The structure is checked at the Accidental Limit State (ALS) to ensure reserve strength and energy dissipation (ductility) to prevent catastrophic failure . Seismic Reserve Capacity ( Crcap C sub r ) : The updated procedure uses a factor ( Crcap C sub r This means the updated standard places a heavier

API RP 2EQ provides guidelines on creating digital twins of offshore assets. This includes modeling the deck mass, the stiffness of the jacket, and the complex damping effects provided by the surrounding water and the foundation piles. Performance Requirements The standard defines two primary levels of performance:
