A standard draft of "Fitness-For-Service assessment "for oil storage tanks was completed by TSM Committee in HPI, sponsored by JOGMEC, in 2007 March. This paper presents the outline of the standard which was completed to keep safe operation against long term material deterioration and⁄or disaster such as corrosion and earthquake. The object components of FFS assessment are shell plate, annular plate, and bottom plate of oil storage tanks. As to failure mode, general metal loss, local metal loss, pitting corrosion, and crack-like flaw are taken into consideration. The assessment procedure is classified into three levels, from "level one" to "level three", in order to promote tank users, such as operators and maintenance engineers in oil stock piling terminals, to use this standard by themselves. This standard is prepared to put emphasis on "level one" procedure in which simple calculation formulas are adopted.
