RTS / overhaul
Bull gear installation & alignment
Gear train inspection, runout and alignment work within the defined overhaul scope.
RTS / Inspection & overhaul
Inspect with purpose.
Restore with precision.
CAT IV drilling equipment inspection and major overhaul support for offshore and onshore assets, from scope definition through controlled reassembly and handover.
A defined inspection programme
Open the equipment.
Understand its condition.
RTS plans inspection and overhaul around equipment type, service history, manufacturer requirements and the applicable inspection standard. Disassembly provides access to the components and load paths that cannot be assessed adequately in normal operation.
- Equipment identification and technical record review
- Strip-down, cleaning and inspection access
- Visual, dimensional and specified non-destructive examination
- Wear assessment and documented repair recommendations
- Replacement, reassembly and agreed verification tests
Scope before mobilisation
CAT IV is a programme.
Not a blanket equipment label.
The inspection category, disassembly extent, NDT method, acceptance criteria and final deliverables are agreed for each asset.
| Equipment group | Typical engineering scope | Basis for the work |
|---|---|---|
| Top drives & hoisting equipment | Load-path components, bearings, shafts, gearing and associated mechanical assemblies. | Applicable hoisting-equipment requirements, manufacturer instructions and the approved inspection plan. |
| Drawworks & mud pumps | Drums, drive trains, power ends, bearings, gears and related lubrication systems. | Manufacturer criteria and the applicable equipment inspection/overhaul requirements. |
| Pipe handling equipment | Hydraracker X-Y, PRS, iron roughnecks, fingerboards and related mechanisms. | Equipment-specific mechanical, hydraulic and functional acceptance criteria. |
| Cranes, jacking & pressure equipment | Condition assessment, repair, test support and specialist inspection coordination. | Asset-specific requirements and competent third-party involvement where required. |
API RP 8B concerns hoisting equipment; it is not applied indiscriminately to every drilling machine. Inspection and recertification requirements are established for the actual asset and contracted scope.
Overhaul workstreams
Mechanical detail.
Documented decisions.
RTS / overhaul
Mud pump assembly & measurement
Bearing and assembly measurements support reassembly decisions.
Project deliverables
A handover your maintenance team can use.
Inspection record
Equipment identification, inspection scope, findings, photographs and measurement records.
Repair disposition
Replacement recommendations, repair decisions, parts identification and agreed deviations.
Verification record
Assembly checks, functional testing and other agreed acceptance records.
Close-out package
Final scope, outstanding recommendations and applicable third-party reports.
Can RTS perform work on site?
Yes. On-site and workshop execution are selected according to access, tooling, equipment condition, lifting requirements and the inspection scope.
Does every overhaul require the same tests?
No. Test methods, loads, pressures and acceptance criteria are established for the equipment and approved work package.
Can RTS help prepare the spare parts budget?
Yes. We can develop a budgetary CAT IV parts list, then refine it after inspection and technical review.
