UNE-EN ISO 19901-2:2026

This document contains provisions for seismic design and assessment of offshore structures.Recommendations for the effects of seismic events on floating structures are introduced.Design and assessment of earthquake-induced ground motions are specifically addressed. Other geologicallyinduced hazards such as liquefaction, slope instability, faults, tsunamis, mud volcanoes and shock waves arebriefly covered.Provisions for site-specific probabilistic seismic hazard analysis are provided for offshore structures in highseismic areas and for offshore structures with high consequence levels.NOTE Guidance and background information relating to the requirements is included in Annex A.
