Seismic strengthening of existing plant facilities have been performed by means of a procedure of the seismic design code of high-pressure gas facilities in Japan. Main purpose of these seismic design codes is to ensure public safety at seismic events. From the viewpoints of seismic risk of corporate management, "Social responsibility of product supply" and "Maintaining the function of facilities and minimizing of damage cost" are also important for seismic assessment. In this paper, authors proposed an assessment method considering those items to select appropriate countermeasures for seismic strengthening, and this method is based on fault tree analysis at allowable damage levels. And a calculation result of a typical example is presented.
