ARC FLASH · SAUDI ARABIA

Arc Flash Studies for Saudi Industrial Facilities

In Saudi Arabia the first question is not how to calculate incident energy. It is whose rulebook governs the asset. A facility inside an Aramco plant is held to SAES-P standards, a giga-project may run its own grid and specification, and everything else sits under SBC 401. The study has to be built for whichever applies.

What Governs an Arc Flash Study in Saudi Arabia

Scope, documentation and permit requirements change with the asset owner, not just with the voltage.

What We Deliver

SBC 401 as the national baseline

The Saudi Building Code electrical requirements, SBC 401-CR, set the national installation code and take IEC 60364 as their basis. For facilities outside Aramco and the giga-projects, this is the standard the installation is assessed against.

WHAT GOES WRONG

Where Saudi Arc Flash Studies Fail

Most failures are scoping failures. The calculation is sound but the study was built for the wrong rulebook, or it cannot be used because the permit and access position was never established.

  • Study scoped to SBC 401 when the asset is governed by Aramco SAES-P.
  • Giga-project sites assessed against the national code rather than the project's own specification.
  • HCIS-driven electrical room constraints ignored when setting working distances.
  • Protection settings taken from design documents rather than verified on site.
  • Permit to work and HSE pre-mobilisation not planned, so field data collection stalls.
  • Labels not revisited after a retrofit changed available fault current.

THE OUTCOMES

What the Report Contains

The report names the governing standard explicitly, because a study that does not say whether it was built to SBC 401 or to SAES-P cannot be relied on by the next reviewer, whether that is an asset owner or an insurance underwriter.

How We Run a Saudi Arc Flash Study

01

Establish the governing standard

Confirm whether the asset falls under SBC 401, Aramco SAES-P, or a giga-project specification, and scope the study to that before any site work.

02

Clear permits and access

Arrange permit to work and HSE pre-mobilisation where the site requires it, and confirm any HCIS constraints affecting electrical room access.

03

Site data collection

Verify the single line diagram, record equipment ratings and conformity, and capture protection settings as found rather than as designed.

04

Model and calculate

Short-circuit study, protection coordination, then incident energy to IEEE 1584 including boundary and working distance per location.

05

Label and report

Labelling plus a report that names the governing standard and records the data behind every result.

Frequently Asked Questions

It depends on the asset. SBC 401-CR, the Saudi Building Code electrical requirements, is the national installation code and takes IEC 60364 as its basis. Inside Aramco facilities the SAES-P series governs instead. Giga-projects such as NEOM and the Red Sea development operate quasi-independent grids with their own specifications under PIF or Royal Commission supervision.
There is no blanket national mandate. In practice they are increasingly required in petrochemical retrofits, driven by insurance underwriters rather than by the building code, and by asset owner standards inside Aramco facilities. The commercial requirement is usually what sets the scope and the deadline.
The High Commission for Industrial Security issues security clearance for critical and energy facilities, and its requirements drive electrical room layout and switchgear specification. Those constraints determine physical access and working distances, both of which are direct inputs to incident energy results and to the PPE conclusions drawn from them.
Equipment imported into Saudi Arabia must carry SASO conformity for the protected categories. For an arc flash study this matters because the protective devices in the model have to be the devices actually installed. We verify equipment and settings on site rather than relying on the design schedule.
