Visual Testing in Villahermosa
Code-required direct or remote visual examination of as-fabricated and in-service surfaces.
ASEA audits Pemex contractor NDT records against NOM-027 and NRF-028 on the same scope — a calibration cert that doesn't map to the specific NRF requirement is a documentary finding before the inspection even starts.
How Visual Testing works
Direct or aided observation (borescope, drone, camera) of surfaces against acceptance criteria for weld profile, surface condition, dimensional compliance and alignment. Required as a pre-step by virtually every other NDT method.
VT in Villahermosa
Visual Testing in Villahermosa is most often pulled into scope when pemex upstream and gas processing or offshore services (bay of campeche) operators need ASEA (Agencia de Seguridad, Energía y Ambiente)-grade evidence that an asset is fit for continued service.

PEMEX Exploración y Producción, PEMEX Logística, and the wider latam operator pool route VT scope through pre-qualified providers — losing a Level II credential here costs real money on outage windows.
PEMEX southern region HQ; Cantarell + Ku-Maloob-Zaap operations. That industrial substrate is what places Villahermosa, Mexico on the short list for VT programme contracts: casing string integrity cadence, NOM-093-STPS (welding + NDT) oversight, and the offshore-field footprint at Cantarell Field (offshore) all push the VT day-rate above generic regional benchmarks.

NOM-093-STPS (welding + NDT) sets the documentary depth VT reports must reach in Villahermosa, Mexico — and PEMEX P.2.0411.01 (NDT specs) layers a second audit trail on top. The method-level reference is BPVC Sec V Art. 9; industry-side, API 5DP is the standard that owners cite in the bid pack. Procedures must demonstrate currency on both before the crew is cleared at gates like PEMEX Exploración y Producción.
