Independent engineering advisory and review across the pressure-equipment, welding and process-safety lifecycle. Document-review services run on a high-throughput review system built for speed and accuracy together: large document sets turn around on short cycles and keep schedules moving; critical and major findings are adversarially verified before they reach you, each stating the code edition it assumes; and every finding carries its source citation — accuracy you can check at the source, not take on trust. Programme build-out and site work (process safety, facility assessments) are delivered as engineer-led advisory under the same evidence discipline.
What we do
Mechanical integrity & pressure equipment
API 510/570 inspection advisory, API 580 risk-based inspection programme support, PER/SANS 347 compliance review, inspection-plan and RBI verification checks.
Welding & materials QA/QC
WPS/PQR and welder-qualification review, fabrication surveillance, ISO 3834 readiness scans, materials and weldability assessments.
Independent NDT report review
UT/PAUT/TOFD, MT, PT and RT report packs checked against acceptance criteria, personnel certification, calibration and coverage claims.
Process safety & risk engineering
PSM/mechanical-integrity programme build-out, HAZOP/What-If/FMECA study support and readiness reviews, MHI 2022 compliance preparation (MIPP, safety reports, licence packs).
Facility & site safety assessments
structured walkdown inspections of buildings and operating facilities against a defined checklist, delivered as a findings report with the completed checklist as the evidence pack; multi-site corporate programmes supported.
Deterministic procedure assurance
step-by-step procedure/ITP follow-and-cross-check audits producing a source-linked deviation register: deviations caught before energy flows, not explained after.
Regulatory & code compliance
PED/CE conformity support, OHS Act / PER reviews, ASME/ISO/EN code compliance checks.
QMS & vendor assurance
ISO 3834 / ISO 9001-style audits, ITP development and review, supplier surveillance.
Failure investigation & RCA
weld, material and equipment failures with a defensible evidence trail.
Engineering document review at scale
drawing/GD&T checks and bulk document QA built for large review scopes.
How engagements run
Fixed-scope review packages (defined deliverable, lump-sum quote), day-rate advisory on- or off-site, or a monthly integrity-desk retainer. Every deliverable ships with its evidence pack — findings traced to their cited clause and source document, with the edition assumed stated.
Scope boundary, stated plainly: this is independent advisory, readiness and review work. Statutory AIA inspections and certification sign-offs remain with accredited inspection authorities — we scope, coordinate and package the evidence; the statutory instrument always belongs to the accreditation holder.
