Historically, seismic design parameters for fixed platforms were governed exclusively by sections within (Working Stress Design). However, the global shift toward harmonizing regional engineering practices led the API to extract and update these seismic provisions.
The standard adopts ISO 19901-2 site seismic zones and specific maps for offshore North America, Africa, and South America, replacing the older maps found in earlier API 2A editions. Why This Matters for 2026 Projects

The standard focuses on reducing risks to personnel, the environment, and assets during seismic events. Key features include: American Petroleum Institute | API Applicability
: It replaces the traditional API seismic maps with the ISO 19901-2 site seismic zones , specifically applying those in Figure B.2 for the U.S. region . Why This Matters for 2026 Projects View global

🔹 – Updated ground motion prediction equations (GMPEs) reflecting recent subduction zone earthquakes. 🔹 Soil-structure interaction – More rigorous liquefaction and cyclic softening criteria. 🔹 Performance-based design – Clearer acceptance criteria for ductility and inelastic response. 🔹 Demand & capacity factors – Revised to match the 22nd edition of API RP 2SIM. region
Ensuring petroleum and natural gas platforms can withstand significant seismic activity without catastrophic failure.
Because API RP 2EQ is a copyrighted technical document, it is usually managed through official distributors like the API Publications Store, IHS Markit, or Techstreet.
Understanding API RP 2EQ: Standards for Seismic Design of Offshore Structures
Applying the performance-based metrics found in the API RP 2EQ guidelines ensures that your offshore assets meet the stringent criteria demanded by global regulatory bodies, safeguarding both human life and marine ecosystems.
