Service overview

Independent structural integrity inspection in Oman.

Structural steel degrades quietly — corrosion under coatings, loosened connections, fatigue at welds. GCS surveys the structure, applies NDT at critical welds and connections, and reports integrity with prioritised remediation so failures are caught before they happen.

Frequently asked

Questions our clients ask most often.

What structures do you inspect?+

Pipe racks, equipment supports, access platforms and stairs, storage tank structures, jetty and marine steelwork, building steel frames and crane runways — anywhere structural integrity affects safety or operations.

How do you find corrosion hidden under coatings?+

We combine visual survey of coating breakdown with UT thickness readings and, where needed, coating removal at sample points and NDT, to quantify section loss and corrosion-under-insulation risk.

What certification do you issue?+

A formal report with photographs, defect lists and recommendations, plus a Certificate of Conformity citing the specific clause references. Hard-copy and electronic certificates are available, and records are retained for audit.

How quickly can GCS mobilise a structural integrity inspection in Oman?+

For routine work in Muscat, Sohar or Duqm, mobilisation is typically within 2 working days. Emergency and post-incident jobs can be mobilised same-day, with reports issued within 5 working days.
