API codes, and the way in which they are written, are an acquired taste. As with all tastes that develop over time, some people eventually acquire it, some pretend to (because it sounds good) and others do not, but just put up with it. API codes are written from the viewpoint of the US refinery industry, so if you are not in the US refinery industry you may find some of the concepts and terminology different. In particular, the system of personnel responsibilities (what the inspector has responsibility for) bears little resemblance to the way that things work in many tank operator companies in the UK and Europe.

This chapter is about learning to become familiar with the layout and contents of API 653. It forms a vital preliminary stage that will ultimately help you understand not only the content of API 653 but also its cross-references to the other relevant API and ASME codes.

API 653 is divided into 13 sections (sections 1 to 13) and nine annexes followed by a large group of figures and 12 tables. Even when taken together, these are not sufficient to specify fully a methodology for the inspection, repair and alteration and reconstruction of storage tanks. To accomplish this, other information and guidance has to be drawn from the other codes included in the API 653 body of knowledge (BOK). Figure 2.1 shows how all these codes work together.
