This part of ISO 19901 contains specific requirements for seismic design procedures and criteria which have to be considered for the installation of fixed steel or concrete offshore structures. Furthermore, the effects of seismic events on floating structures are briefly treated in this standard. For high seismic and/or high exposure level structures, a site-specific seismic hazard assessment is required. For such cases the procedures and requirements for a site-specific proabilistic seismic hazard analysis are addressed.
