INFO
The above-mentioned inspection intervals refer to a
100% use of the SBE on each day of a
week
(24 / 7)

according to the type and extent of use and may
need to be adjusted. All inspection categories are in
accordance with the latest API RP 8B.
Ensure that maintenance work is
accomplished only by sufficiently
qualified and trained personnel.

Inspection Following Critical Loads
Perform an inspection IMMEDIATELY following any critical
or unexpected loads. Critical loads could be:
- Loads resulting from shock when the drill pipe wedges.
- Pulling wedged drill strings.
- Holding heavy drill pipes / drill strings.
- Jarring.
- Operation at very low ambient temperatures
(< - 20°C to - 4°F).

Inspection Following Removal
Generally the SBE should be inspected immediately before
it is taken out of service temporarily or stored. Moreover it
should be inspected before putting back into service.
- It is necessary to disassemble the SBE in an
appropriately equipped workshop to check for excessive
wear, deformation, cracks and other damage.
- Perform repair work only in compliance with the
manufacturer's recommendations. These are available
from Forum B + V Oil Tools.
- If the field inspection indicates that further inspection
work is required, remove the SBE
and have it inspected
in an appropriately equipped workshop.
6.3
Inspections
Forum B + V Oil Tools recommends to perform inspections
in compliance with API RP 8B at specified intervals and in
inspection categories. Otherwise the frequency of required
inspections depends on the conditions of use of the SBE
Before inspection, remove all foreign material such as dirt,
paint, lubricants, oil, abrasion, etc. from the affected parts.
Use suitable methods such as stripping off paint, steam
cleaning or sand blasting.
After an inspection the scope and results of the tests
performed has to be documented.
Periodic inspections and inspections following critical
assignments should be accomplished at the operating
location by the operators under the supervision of a
supervisor.
In the event of cracks, excessive wear, etc. contact
Forum B + V Oil Tools or an authorized service company.
