Turnaround & Shutdown Support
Multi-unit exchanger scopes executed inside turnaround windows — planned, mobilised and delivered by one accountable contractor.
Why This
Matters
The wrong specification here doesn't show up on day one — it shows up as downtime, contamination or wasted energy later.
Asset protection
Turnarounds are when hidden exchanger damage is found — without workshop backup and materials on standby, discoveries become extensions, and every extension day is scoped, costed and defended after the fact.
Process integrity
Rushed reassembly causes the leaks that force early shutdowns; disciplined bolting and testing protect the next run length far more than schedule compression during the final days of a turnaround.
Operational efficiency
Every day of turnaround overrun costs more than the entire exchanger scope — planning and parallel execution are the insurance against a single bottleneck package delaying unit restart.

Turnaround exchanger scope succeeds or fails before the plant comes down. Our model front-loads planning and holds workshop capacity in reserve for discoveries.
- 1
Pre-TA survey: scope walkdown, historical data review, and per-unit work packs months ahead.
- 2
Materials staged: gaskets, tubes, fasteners and spares procured and kitted per exchanger.
- 3
Execution: parallel crews pull, clean, test and repair to the work packs with daily progress reporting.
- 4
Discovery management: Mussafah workshop capacity on standby absorbs emergent repairs without extending the window.
- 5
Reinstatement: controlled bolting, testing and documented handover unit by unit.
Configurations
We Offer
Every variant Dolphin builds — each engineered for a specific duty, not a catalogue default.
Full Exchanger Scope
- Best For
- Operators who want one accountable exchanger contractor.
- Advantage
- Single interface from planning to handover — no vendor coordination burden.
Specialist Support
- Best For
- TAs with an incumbent mechanical contractor.
- Advantage
- We deliver the specialist portion: cleaning, tube testing, retubing, code repair.
Emergency Reinforcement
- Best For
- TAs already in trouble.
- Advantage
- Crews and workshop capacity mobilised mid-window to recover schedule.
How to
Choose
| Criterion | Guidance |
|---|---|
| Scope definition | Per-unit work packs built from inspection history — not discovered at bundle pull. |
| Window duration | Crew size and shift pattern engineered backwards from the critical path. |
| Discovery risk | High-uncertainty units get pre-priced repair options and standby materials. |
| Site requirements | ADNOC-inducted, HSE-certified crews with site-specific permits arranged ahead of mobilisation. |

Why Dolphin for
Turnaround & Shutdown Support
Window discipline
A 34-exchanger scope delivered on schedule inside a 28-day window is our reference standard, not our exception.
Workshop as insurance
Emergent damage moves to Mussafah and back inside the window — capability no crew-only contractor can offer.
Operator compliance built in
Inductions, certifications and HSE systems aligned with ADNOC and major operator requirements.
Frequently Asked Questions
Ideally 4–6 months out: scope surveys, work packs and material procurement all happen before the window opens.
Crews scale to campaigns beyond 100 units, with parallel workfronts and workshop overflow at Mussafah.
Pre-priced repair options, standby materials and workshop capacity absorb discoveries — the answer is execution, not a change-order negotiation.
