: The standard moves away from the older Strength Level Earthquake (SLE) and Ductility Level Earthquake (DLE) terminology, adopting a two-tier approach:
: API 2EQ replaces the older API 2A-WSD seismic maps with ISO 19901-2 site seismic zones and specific maps in Figure B.2 of the document.
Limited previews or older versions are sometimes found on platforms like ResearchGate for educational reference. Accuris Standards Store Core Technical Changes
API RP 2EQ (Seismic Design Procedures and Criteria for Offshore Structures) is the primary industry standard for managing earthquake-induced risks for offshore platforms. The current version remains the 1st Edition (2014) , which was officially reconfirmed in January 2021 to ensure its continued technical relevance. Key Components of the Latest Version The standard functions as a modified adoption of ISO 19901-2
This update introduced minor technical corrections and refined specific seismic risk parameters to better align with evolving metocean data.
: The guidelines apply to fixed steel and concrete structures, with additional considerations for floating or partially buoyant platforms.
