If the _______________ of a vessel are changed, the inspection intervals shall be established for the new service conditions.

Service Conditions

2

If both the ownership and the location of a vessel are changed, the vessel shell be __________ and __________ inspected before it is reused.

Internally and Externally

3

When a RBI interval for the internal or on-stream inspections exceeds the 10-year limit, the RBI assessment shall be reviewed and approved by the engineer and inspector at intervals not to exceed __________ or more often if warranted by process, equipment or consequence changes.

10 Years

4

Unless justified by an RBI assessment, each above ground vessel shall be given a visual external inspection at an interval that does not exceed the lesser of __________ years or the required internal/on-stream inspection.

Five

5

Unless justified by a RBI assessment, a vessel with more than 4 years remaining life shall be inspected _______________.

Lesser of Half Life or 10 Years

6

Unless justified by a RBI assessment, a vessel with 4 years or less remaining life shall be inspected _______________.

Lesser of Half Life or 2 Years

7

For pressure vessels that are in _______________, the interval is based on the number of years of actual service.

Training Program

11

Pressure-relieving devices shall be tested and inspected at intervals that are frequent enough to verify that the valves _______________ in the particulat service conditions.

Perform Reliably

12

Unless documented experience and/or a RBI assessment indicates that a longer interval is acceptable, test and inspection intervals for pressure-relieving devices in typical process services should not exceed:
a. __________ years for typical process services
b. __________ years for clean (nonfouling) and noncorrosive services.

a. Five Years
b. Ten Years
