Scope

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 geologically induced hazards such as liquefaction, slope instability, faults, tsunamis, mud volcanoes and shock waves are briefly covered.

Provisions for site-specific probabilistic seismic hazard analysis are provided for offshore structures in high seismic areas and for offshore structures with high consequence levels.

NOTE Guidance and background information relating to the requirements is included in Annex A.
