3.15 REPAIR AND SERVICE MANUAL
Chapter 3 GROUND WATER FACILITIES
Inspection establishes a definite procedure for recognising changes in appearance, sound and feel.
Inspections have two types:
a. Continuing- A continuous monitoring of the operation of the equipment.
b. Periodic- A regular check of certain features
Inspection involves more than looking at the equipment and checking a few gauges or indicators.
The driller must have a lot of knowledge and understanding about his rig and equipment before he
can carry out any worthwhile inspection. The driller must:
- know the correct condition of the equipment and correct gauge readings,
- understand how the equipment works and to know where to look for critical wear or other
deficiencies,
- understand stresses in the components to assess how safe they are,
- know the safe way to handle all tools and equipment and,
- keep the rig clean and tidy so that inspections can be made easily and effectively
Some features require daily attention, others are service frequently. As well as following the service
schedule for the rig as set out in the manual, a driller will make daily check on:
- Rig stability
- Rig position
- Mast vertically
- Condition of mast, wire ropes and hoses
- Condition of hole collar
- Fluid level in the hole
- Stock of fuel, lubricants an drilling materials
- Availability of fishing and servicing tools to suit equipment currently in use or likely to be used.
A driller’s programme of ‘continual inspection’ of the equipment will include checks and observation
of gauges, dials, indicators.
