A shutdown is not a normal manpower requirement running at a different speed. The dates do not move, the peak is short and steep, the whole region competes for the same trades in the same weeks, and every worker has to clear site induction and permit requirements before the window opens rather than during it.
Gulf Orbit supplies the trades a turnaround actually consumes — scaffolders and helpers for access, welders and pipe fitters for the mechanical scope, riggers and crane operators for lifting, mechanical fitters for equipment work, and the supervision to hold it together — planned against your shutdown programme rather than against a monthly headcount.
What shutdown and turnaround manpower covers for projects in Saudi Arabia.
Crews are sized to the ramp-up, the peak and the demobilization rather than held flat across the period.
Scaffolders, welders, pipe fitters, riggers, mechanical fitters, crane operators, insulators and supervision from one register.
Worker documentation is submitted for approval ahead of the shutdown, so induction does not eat into the window itself.
Headcount changes during the window go through one Gulf Orbit contact, against the curve agreed in the RFQ.
Direct answer
Gulf Orbit supplies shutdown and turnaround manpower across Saudi Arabia — scaffolders, welders, pipe fitters, riggers, mechanical fitters, insulators and supervision — mobilized against fixed outage windows for refineries, petrochemical plants and industrial facilities. Gulf Orbit has supplied turnaround and outage crews in Jubail Industrial City, Ras Tanura and Yanbu, and crews mobilize within 48–72 hours of the purchase order, subject to worker documents and site approvals.

On a construction project a late crew costs float. In a turnaround it costs production, and the date the plant comes back is usually fixed before the scope is final. That changes what matters: not the headline rate, but whether workers are documented, inducted and at the gate on day one, with the right cards for the site.
A turnaround is a set of work packages: access, static equipment, piping and valves, rotating equipment, lifting, electrical and instrumentation, and reinstatement. Each has its own crew and its own peak. Scaffolders come first for access; fitters, welders, riggers, crane operators and E&I technicians peak inside the window; scaffolders leave last after box-up. The trades by package are set out in manpower for a refinery turnaround.
Shutdown manpower is never flat. There is a ramp-up while access goes in, a peak while the mechanical scope runs, and a taper as systems are reinstated. A requirement that gives those phases and their dates can be crewed to the curve. One average number is over-resourced at both ends and short in the middle.
Turnaround demand in the Eastern Province concentrates in the same seasons, and welders, scaffolders and riggers are the trades that run out first. A requirement raised two months out competes in a different market from one raised two weeks out. Send the window dates as soon as they are fixed, even before the scope is final. The shutdown manpower planning checklist lists what to decide first.
Worker documentation is submitted for your approval ahead of the window, so induction and gate passes do not consume days of the outage. TUV-carded workers are available for trades that require a TUV card, such as scaffolders, riggers and crane operators; Aramco-certified and non-Aramco workers are both available. Welders are qualified by WPQ to your procedure. Every worker completes Gulf Orbit's safety induction before mobilization; site-specific training is confirmed per site.

Turnaround managers often choose between supplied manpower working under their own planning team and a subcontractor delivering whole work packages. Many outages use both. The table shows the difference.
| Question | Manpower supply | Work-package subcontract |
|---|---|---|
| Who plans the work packages | Your planning team | The subcontractor, against your scope |
| Who supervises the crews | Your supervisors, with supplied foremen if requested | The subcontractor |
| How it is priced | Per worker for the period, by trade and shift | Per package or unit rate |
| Fits when | You have the planning and supervision and need trades | You want a package delivered and handed back |
Send the plant and city, window start and finish dates, the trades and headcount per phase, the shift pattern including nights, card and induction requirements, any qualification tests, and whether accommodation and transport are provided; they are quoted on request. Partial information sent early beats complete information sent late. Send the RFQ.
Gulf Orbit has supplied turnaround and outage crews in Jubail Industrial City, Ras Tanura and Yanbu. Crews for other plants anywhere in Saudi Arabia are quoted against the same RFQ.
TUV-carded workers are available for trades that require a TUV card, such as scaffolders, riggers and crane operators. Aramco-certified and non-Aramco workers are both available. Card copies are sent with CVs for your approval before mobilization.
As soon as you have the window, even if the scope is not final. Availability inside a fixed window is the constraint, and welders, scaffolders and riggers run out first.
Yes. Scaffolders, welders, pipe fitters, riggers, mechanical fitters, crane operators, E&I technicians and supervision come from one register, so a mixed crew is proposed against your scope.
Yes, and it is worth planning for. Worker documentation is submitted for your approval ahead of mobilization so induction and gate passes do not take days of the outage.
State the shift pattern in the RFQ, including night shifts and rotations, because it changes crew size and the accommodation and transport plan.
Send the expected curve with the RFQ so the ramp-up and taper are planned. Changes during the window go through one Gulf Orbit contact and are confirmed against availability.
