Definition Inspection

What is meant by inspection in this case is a way or method of doing inspection work equipment technical condition that the working tool can be operated efficiently and safely (do no harm).

Stages Inspection

The inspection work should be carried out starting from planning (Design) until the time of surgery to maintain. Construction design must be checked carefully.

In the manufacturing process of construction, Inspector can give guidance positive in order to produce construction that meet technical requirements, During construction of the operation, inspectors conduct a review of the results of the technical condition and operating conditions of construction and examines the data record to be used as a source of information at a future time (Next) ,

Data record (history file) will be very helpful for the preparation of the next maintenance program.

Inspection planning

Before inspection activities carried out, inspectors should be able to analyze or examine whether all the requirements of the code / regulations are included in the inspection plan and test (Inspection Test Plan / ITP) made by the manufacturer (for pressure vessel new) or owner ( for pressure vessel attached) and signed by all parties concerned. Any changes that have been agreed to be concluded and signed together, and then documented in the project implementation. In performing their duties, inspectors should refer to all regulation, code or procedures applicable.
