Works and services offered by NTC NefteGazDiagnostika LLC per equipment types:

Pipelines and piping

Coating condition inspection:

• Searching and locating pipeline axis in the field including underwater inspection
• Identifying potentially hazardous segments and damaged coating areas, areas of pipeline wall metal removed by earth currents
• Inspecting pipeline cathodic protection systems
• Identifying the pipeline coating remaining life

Parent metal and welds inspection:

• Acoustic emission inspection and pipeline metal defects isolation (weld cracks, yielding areas, metal thickness reduction, corrosion, holes)
• Magnetic memory method inspection
• Metal defects identification: visual inspection, UT, MPI, DPI, IT, radiographic and other non-destructive inspection methods

Inline inspection:

• Pipeline cleaning
• Pipeline gauging
• Geometry inspection using an electronic geometry pig (EGP)
• Pipeline MFL inspection using 3rd generation high resolution pigs (CDP)
• AFD inspection to identify longitudinal defects with high resolution 2nd generation inspection pigs
• GYRO-inspection to identify the pipeline axis and detected defects coordinates (XYZ)

Restoring pipeline normal operation:

• Repairing all types of defects including penetration defects identified following inspections using UKMT composite sleeves (permanent repair method) including offshore pipelines

Industrial safety expert review:

• Expert review of the technical documentation and the pipeline itself compliance to standards and technical documentation requirements
• Remaining life calculation, strength and other calculations
• Issuing opinions regarding future operation possibilities and timelines

Surveying and mapping:

• Topographical surveying and mapping of the pipeline right-of-way with GPS references of the pipeline kilometer points
