ABS Service Supplier Audit Preparation for Inspection Companies
A ABS Service Supplier audit runs in 5 stages, beginning with submit the online request form to abs for the named service types. American Bureau of Shipping (ABS); certification issued exclusively by ABS tests the system by sampling finished work backwards to the records behind it, so preparation means reconciling records to jobs rather than rewriting manuals.
ABS recognizes service suppliers so that its surveyors can accept their results. It is a company-level certification: ABS performs a technical documentation review, a facility and quality system assessment, verification of personnel qualifications, and a performance evaluation through practical demonstration, then issues a Recognition Certificate and lists the firm in the ABS Global Service Supplier Database with its scope, certificate validity and assigned ABS port office. The commercially distinctive point is that ABS recognizes NDT/NDI/NDE as an ABS Rule-required service in its own right — a separate entry point from hull gauging for an inspection company doing weld examination on ABS-classed newbuilds and repairs. What separates firms that clear an audit from firms that collect findings is not the quality of the documentation but whether it describes what actually happens. The finding recorded most often is: NDT procedures in use were never approved and signed by a Level 3 certified in that method

| Stage | What happens | What it tests |
|---|---|---|
| Stage 1 | Submit the online request form to ABS for the named service types | Where the paperwork is tested against itself |
| Stage 2 | Documentation review by ABS of the quality system, procedures and personnel records | Where the paperwork is tested against practice |
| Stage 3 | Facility audit, including assessment of the quality system and verification of personnel qualifications | Where the paperwork is tested against practice |
| Stage 4 | Practical demonstration of the specific service, witnessed by ABS | Where the paperwork is tested against practice |
| Stage 5 | Satisfactory performance and reporting confirmed, then issue of the Recognition Certificate and listing in the ABS Global Service Supplier Database | Where the paperwork is tested against practice |
| Renewal | ABS's published service supplier material states the Recognition Certificate is valid for five years. Certain service types are marked as subject to annual audits — ABS CyberSafety services, integrated software quality management, pressure vessel manufacturers and smart functions. Where the service falls in the Regulatory and Statutory (IACS UR Z17) family, the underlying Unified Requirement caps renewal for thickness measurement firms at three years, so hull gauging approvals run on a shorter clock than the general five-year figure. | Diarised from the certificate date, not the last audit |
How long does ABS Service Supplier audit preparation take?
Document work — the written practice, procedures and quality manual — takes weeks. What cannot be compressed is documented experience and records history: on-the-job hours accrue in real time, and calibration and certification history cannot be back-filled. Firms that start when the audit is scheduled rather than announced clear it without findings.
What does American Bureau of Shipping (ABS); certification issued exclusively by ABS look at first?
Records, not manuals. A manual states intent; records show practice. The usual opening move is to take a completed job and trace it back to the technician's certification, the instrument's calibration, the approved procedure and the report — and see whether all four reconcile.
What are the most common ABS Service Supplier findings?
NDT procedures in use were never approved and signed by a Level 3 certified in that method, Interpretation and evaluation of indications performed or signed off by Level 1 personnel, Personnel certificates present but not traceable to a written practice or a recognized certifying program, Scope creep — services performed that are outside the service types written on the Recognition Certificate. Almost all of them are evidence problems rather than capability problems: the work was done correctly and the proof was not kept, or was kept somewhere the firm could not retrieve during the audit.
Can a consultant attend the ABS Service Supplier audit?
Yes, and it changes the outcome. Someone who has sat through the same audit at other firms answers in the auditor's own terms, produces the right record without a search, and stops a clarification turning into a finding. The firm still owns every answer — the consultant does not speak for it.
What happens after a ABS Service Supplier finding?
A corrective action with a deadline, and evidence of closure at the next audit. Repeat findings are treated far more seriously than first ones, because they show the corrective-action system itself is not working.
Does ABS Service Supplier require a pre-audit or gap assessment?
Not as a requirement, but the arithmetic favours it: a gap assessment finds the same evidence problems the auditor would, without the finding attached, and while there is still time to fix them. Firms entering their first ABS Service Supplier audit blind typically collect findings that a sampling exercise would have caught.
What the auditor asks to see
- Completed ABS Service Supplier online request form identifying every service type sought
- Quality manual and documented work procedures covering each service type applied for
- Personnel list with certificates, training records and documented experience for every operator and supervisor
- NDT procedures and techniques signed by a Level 3 in the applicable method, for the NDT/NDI/NDE service type
- Equipment list with maintenance, calibration and verification records
- Report formats and check lists used to record the results of the service
- Evidence of approval, recognition or accreditation held from other bodies
- Records of customer complaints and of corrective actions taken
- Information on other activities that could present a conflict of interest
Findings to close before the audit
- NDT procedures in use were never approved and signed by a Level 3 certified in that method
- Interpretation and evaluation of indications performed or signed off by Level 1 personnel
- Personnel certificates present but not traceable to a written practice or a recognized certifying program
- Scope creep — services performed that are outside the service types written on the Recognition Certificate
- Practical demonstration deferred, so the certificate scope was never fully activated for one of the applied-for services
- Equipment calibration records incomplete, or no assessment of prior results when equipment was found out of tolerance
- Subsidiary or branch office operating under the head office certificate without having been assessed
- Conflict-of-interest information not disclosed where the firm also performs repair work on assets it inspects
