DNV certified gas manifold — verified design and documented testing for the deck
A DNV certified gas manifold is distinguished by its documentation: verified design, traceable materials, witnessed tests and a certificate that follows the unit through its working life. REAL GAZ provides manifolds supported by that kind of record.
This matters when a rig or vessel must demonstrate to class, charterer or authority that its gas system is fit for service.

Typical supporting documents include DNV-ST-E271, EN 10204 3.1 material certificates, PED 2014/68/EU conformity and ISO 9606 welder qualifications.
A certificate is only useful if it is linked to the equipment it describes. Each manifold therefore carries a stamped nameplate with a unique serial number, which appears on the test certificate, the material certificates and the as-built drawing. If a component such as a regulator or relief valve is later replaced, the replacement is entered in the history file, along with the date and the technician. Periodic re-inspection, usually annual, checks for corrosion, loose supports, leaking joints and gauge accuracy, and relief valves are tested or exchanged at defined intervals. Because the records are kept together, an audit becomes a matter of opening a single folder rather than searching for scattered papers, a point that class surveyors and insurers regularly appreciate.
