DNVGL-CP-0376: Type Approval for Robotic Inspection Systems
Standard for robotic and automated inspection systems used in pipeline and structure inspection. DNVGL-CP-0376 ensures quality and reliability of automated NDT systems.
DNV GL maintains DNVGL-CP-0376 as a published consensus standard used across the NDT industry.
DNVGL-CP-0376 becomes enforceable when invoked by a contract, regulatory citation, or another standard that references it as the controlling document.
DNVGL-CP-0376 is invoked when the scope of work matches its title — type approval for robotic inspection systems — and when the contract or regulatory regime cites it as the controlling document. On petroleum and petrochemical equipment, DNVGL-CP-0376 usually feeds into a written mechanical-integrity program: inspection intervals, examination methods, and acceptance criteria are all traced back to a clause number in the document.
Methods covered
Industries
- Oil & Gas
- Pipeline
- Subsea
- Personnel qualification: examinations under DNVGL-CP-0376 must be performed by inspectors qualified and certified to a recognised scheme (typically ASNT SNT-TC-1A, CP-189, or ISO 9712 depending on jurisdiction), with documented training hours, vision tests, and a controlling written practice.
- Written procedure: every examination requires a written, controlled procedure that names the method, equipment, calibration steps, scanning pattern, and acceptance criteria — and is qualified before first use.
- Acceptance criteria: indications are evaluated against the standard's tabulated limits (length, depth, alignment, frequency); any indication exceeding the criteria is recorded, dispositioned, and either repaired or evaluated for fitness-for-service.
- Documentation: examination reports must include enough information for a third party to reproduce the inspection — equipment serial numbers, calibration records, inspector ID, sketches of indications, and the controlling procedure revision.
DNVGL-CP-0376 is maintained on its publishing organisation's revision cycle. The version cited in any contract or written inspection program should be tracked so that revisions can be reviewed against the existing inspection plan and any clause changes worked into the next procedure update.
A typical refinery turnaround applies DNVGL-CP-0376 to the inspection scope for high-temperature piping and pressure vessels: corrosion-monitoring locations are read with UT thickness gauges, girth welds on repaired sections are radiographed or PAUT-scanned, and any indication outside the standard's acceptance table is dispositioned through API 579 fitness-for-service before the unit restarts.
What does DNVGL-CP-0376 cover?
DNVGL-CP-0376 (Type Approval for Robotic Inspection Systems) is published by DNV GL. Standard for robotic and automated inspection systems used in pipeline and structure inspection.
Is DNVGL-CP-0376 mandatory or voluntary?
DNVGL-CP-0376 is a consensus standard. It becomes mandatory when invoked by a contract, by another code that cites it (for example ASME Section V calling out an ASTM practice), or by a regulator that has adopted it into law in a specific jurisdiction.
Who is qualified to perform inspections under DNVGL-CP-0376?
Inspections under DNVGL-CP-0376 must be performed by personnel qualified and certified to a recognised NDT certification scheme — most commonly ASNT SNT-TC-1A or CP-189 in the United States, ISO 9712 in much of the rest of the world, and NAS 410 for aerospace work. The written practice that controls qualification must be in place before any examination is started.
Which other standards are commonly cited alongside DNVGL-CP-0376?
DNVGL-CP-0376 is most often cited together with the parent code that brings it into the contract — typically ASME Section V or VIII for U.S. pressure equipment, AWS D1.1 for structural welding, API 510/570/653 for in-service petroleum equipment, or the matching EN/ISO standard for European and international work.
