ABS Service Supplier Compliance for Inspection Service Providers
Service providers seeking ABS recognition in one of three families: regulatory and statutory services aligned with IACS UR Z17; services required by ABS Rules and Guides, which explicitly include nondestructive test, nondestructive inspection and nondestructive evaluation. Personnel are qualified under employer-based certification, so a contracted Level III can sign the written practice and administer examinations for the firm.
Service providers seeking ABS recognition in one of three families: regulatory and statutory services aligned with IACS UR Z17; services required by ABS Rules and Guides, which explicitly include nondestructive test, nondestructive inspection and nondestructive evaluation; and miscellaneous programmes such as testing laboratories, inspection and maintenance services and asset layup. It binds the company and the named service scope, not individual technicians. 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.

Who does ABS Service Supplier apply to?
Service providers seeking ABS recognition in one of three families: regulatory and statutory services aligned with IACS UR Z17; services required by ABS Rules and Guides, which explicitly include nondestructive test, nondestructive inspection and nondestructive evaluation; and miscellaneous programmes such as testing laboratories, inspection and maintenance services and asset layup. It binds the company and the named service scope, not individual technicians.
Can an outsourced Level III sign for ABS Service Supplier compliance?
Yes. ABS Service Supplier accepts employer-based certification, which places the obligation on the employer and allows a contracted Level III to write and sign the written practice, approve procedures and administer examinations. The Level III must be qualified in each method they sign for, and the employer still owns the records.
What documents does a ABS Service Supplier audit ask for?
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. Auditors open records before they open manuals, because a manual describes intent while records show practice. The most common failure is a documented system that does not match what the technicians actually do.
How often is ABS Service Supplier renewed?
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. Firms that diarise renewal from the certificate date rather than from the last audit avoid the lapse that forces a full reapplication.
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. These recur because they are records problems rather than capability problems — the work is being done correctly and the evidence is not being kept.
Which NDT methods does ABS Service Supplier cover?
UT (hull gauging and ultrasonic thickness measurement), UT (weld examination), RT, MT, PT, VT, Remote inspection techniques (drones, ROVs, robotic crawlers). Each method in scope needs its own approved procedure and personnel qualified in that specific method; a Level III qualified in ultrasonics cannot sign for radiography.
Personnel certification under ABS Service Supplier
Employer-based certification is accepted; ABS verifies certificates rather than issuing them, and personnel qualification verification is a formal step of the approval. ABS's own nondestructive inspection guidance sets the authority split an auditor tests against: procedures and techniques are to be established and approved by personnel certified to NDT Level 3 in the applicable method; inspection may be performed by certified Level 1, 2 or 3 personnel; interpretation and evaluation of results must be performed by Level 2 or 3. It references ISO 9712 and recognized international or national certifying programs as the qualification basis. An outsourced Level III can therefore write and sign the firm's NDT procedures and techniques.

- 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
