API RP 8B:2002 pdf download.Recommended Practice for Procedures for Inspections, Maintenance, Repair and Remanufacture of Hoisting Equipment.
4.1.2.1 User owner and manufacturer joint procedure development
The user/owner and manufacturer should jointly develop and update inspection, maintenance, repair and remanufacture procedures consistent with equipment application, loading, work environment, usage, and operational conditions.
These factors may change as a result of new technology, product improvements or fundamental changes in service conditions.
4.1.2.2 Userlowner procedure development
If the manufacturer of the equipment no longer exists or is unable for any reason to provide suitable recommendations, the user/owner shall develop inspection, maintenance, repair and remanufacture procedures consistent with widely-accepted industry practices.
4.1.2.3 Parts and tooling
NDT, maintenance, and dismantling equipment shall be properly selected and adapted to the parts to be inspected and maintained.
4.2 Personnel qualification
4.2.1 NDT personnel qualification levels
4.2.1.1 Qualification
Inspectors shall be aware of the type of equipment to be evaluated and the NDT methods to apply. The users/owners shall verify that the NDT inspector has the following information:
— assembly drawings and drawings identifying critical areas;
— rejection cntena.
In addition, the users/owners may provide the history of grinding or remanufacture, if available.
In the absence of critical area drawings, all areas of primary-load-carrying components shall be considered critical. These data shall be used by the inspector to adapt the inspection procedure.
4.2.1.2 Certification
The NDT inspector shall be certified according to ISO 9712 or by other recognized NDT certification programmes
or standards.
4.2.2 Welding personnel qualification levels
Welders shall be qualified to a recognized standard.
If any manufacturing defects are discovered, they should be reported to the manufacturer or supplier.
5.3.2 Inspection categories
5.3.2.1 General
The objective of these inspections is to detect service defects and possible hidden manufacturing defects.
Inspection results shall be reported on equipment files and drawings.
5.3.2.2 Category I
This category involves observing the equipment during operation for indications of inadequate performance.
When in use, equipment shall be visually inspected on a daily basis for cracks, loose fits or connections, elongation of parts, and other signs of wear, corrosion or overloading. Any equipment found to show cracks, excessive wear, etc., shall be removed from service for further examination.
The equipment shall be visually inspected by a person knowledgeable in that equipment and its function.
5.3.2.3 Category II
This is Category I inspection plus further inspection for corrosion, deformation, loose or missing components,
deterioration, proper lubrication, visible external cracks, and adjustment.
5.3.2.4 Category III
This is Category II inspection plus further inspection, which should include NDT of critical areas and may involve some disassembly to access specific components and to identify wear that exceeds the manufacturer’s allowable tolerances.
5.3.2.5 Category IV
This is Category Ill inspection plus further inspection for which the equipment is disassembled to the extent necessary to conduct NDT of all primary-load-carrying components as defined by manufacturer.
Equipment shall be:
— disassembled in a suitably-equipped facility to the extent necessary to permit full inspection of all primary-load-carrying components and other components that are critical to the equipment;
— inspected for excessive wear, cracks, flaws and deformations.
Corrections shall be made in accordance with the manufacturer’s recommendations.
Prior to Category Ill and Category IV inspections, all foreign material such as dirt, paint, grease, oil, scale, etc. shall be removed from the concerned parts by a suitable method (e.g. paint-stripping, steam-cleaning, grit-blasting).
5.3.3 Frequency
5.3.3.1 Periodic inspection
The user/owner of the equipment should develop schedules of inspection based on experience, the manufacturer’s recommendations, and one or more of the following factors:
environment;
– load cycles;
regulatory requirements;
-operating time;
-testing;
repairs;
remanufacture.
As an altemative, the user/owner may use Table 1 guidelines. Long-term planning shall be adjusted in order not to interfere unnecessarily with the running operations.
5.3.3.2 ;
Non-periodic inspection
A complete, on-job, shut-down inspection equivalent to the periodical Category I or Category IV (for the concerned equipment) should be made before (if anticipated) and after critical jobs (e.g., running heavy casing strings, jarring, pulling on stuck pipes and/or operating at extreme low temperatures).
