For example, Figure 1-26 represents one of many steam-turbine latching and
startup instructions that was developed for both purposes, that is, reference
information and field-posted instructions. The vendor should be contractually
obligated to prepare these and similar illustrated instructions.
Figure 1-27 belongs in the surveillance data category. This tabulation pro-
vides key input for vibration spectrum analysis techniques that are an indis-
pensable troubleshooting tool for modern process plants. Again, the data should
be provided by the equipment vendor before plant startup. Efforts to acquire
this information after the equipment vendor has received full payment for
machinery and services are usually quite costly and frustrating.
2. Equipment specification sheets, such as API data sheets and supplementary data
used at time of purchase.
3. Cross-section drawings showing the equipment assembly. These drawings must
be dimensionally accurate. Dimensional outline drawings should also be included.
4. Bill of materials or complete parts list identifying components and materials of
construction.
