Solution
Minimize overhaul downtime and keep your rigs productive
A structured approach that shortens overhaul windows, prevents repeat inspections, and protects revenue without compromising rig integrity.
Download the whitepaperThis solution supports operators planning Category IV (≈10-year) rig overhauls, asset teams facing long outage windows or documentation re-work, and multi-rig fleets that need predictable schedules with less idle time across the portfolio. You receive a clear plan with firm dates, right-first-time documentation, and shorter downtime through disciplined critical-path compression.
Where this solution delivers best
Category IV (Cat IV) rig overhauls with long outage windows
Fleets exposed to cascading delays across multiple rigs
Operations struggling with late scope freeze, long-lead spare shortages, or documentation re-work
Programmes requiring predictable schedules and reduced idle days
How the solution works
Before execution, the outage window is stabilised by freezing scope early with OEMs, validating the BOM and long-lead items, and confirming the full outage calendar. This prevents late surprises and enables precise planning across all stages.
1. Align and freeze scope early
From D-90 to D-30, scope is locked with OEMs, the BOM is validated, long-lead requirements are confirmed, and high-risk tasks are sequenced early. Daily stand-ups and look-ahead planning ensure owners and OEMs stay aligned.
2. Build a complete, indexed workpack
From D-45 to D-15, a single workpack is created containing inspection sheets, drawings and ITPs. Evidence requirements such as photos, serials and torque logs are defined upfront. A QC checklist ensures documentation is sign-off ready and avoids repeat inspections.
3. Stage spares and stabilise supply chain
From D-30 to D-7, spares are pre-staged at the point of use and tagged by task and sequence. Vendor arrival windows are confirmed to prevent congestion. BOM risks are mitigated using approved alternates or pre-cleared substitutions.
4. Execute with critical-path discipline
From D-0 to D+X, independent tasks are parallelised while the critical path is protected. Daily recovery planning adjusts downstream sequences immediately when slippage appears. Document QC is performed on the spot, and no task closes without evidence.
5. Close out and feed learning forward
During the final week, all evidence is collated into a complete handover dossier. Lessons learned are captured within 48 hours and fed directly into the next rig’s plan to prevent repeat issues across the fleet.

What our partners gain
Performance improves through shorter overhaul windows, higher documentation accuracy and more predictable schedules across the fleet.
Shorter outage windows. Critical-path discipline compresses schedule duration and prevents cascading delays across rigs.
Right-first-time documentation. Front-loaded QC and evidence checklists eliminate repeat inspections caused by incomplete documentation.
Stronger supply chain readiness. Long-lead exposure is reduced through early BOM validation, alternates approval, and precise vendor scheduling.
Predictable schedules and reduced risk. Daily look-ahead planning, staged spares, and structured governance improve programme predictability and reduce schedule risk for multi-rig fleets.
A structured governance model led by the Abraj PMO keeps owners, OEMs and vendors aligned and maintains control across every stage of the overhaul window.
Frequently asked
Do we trade speed for quality?
No. The method removes waiting and re-work, not scope. Structural integrity and compliance remain non-negotiable.
What if two rigs need Cat IV at the same time?
Programme planning staggers outages, shares the supply chain, and prevents stacked idle time. Across programmes, Cat IV idle days were materially reduced with no documentation-driven repeat inspections. Full detail is available in the whitepaper.
