OilcrewsInc offers a unique and complete package of inspection, maintenance, hookups and repair
disciplines satisfying most if not all major Oil & Gas company and rig contractors' requirements.
Our inspection services include comprehensive reporting tailored to the clients needs. Our priorities in
the inspection discipline are safety first and we believe in quality report writing. We understand that
the client is not always present for the inspection on site and realise the importance of explicit report
writing - this involves recommendations for repair. Any structural recommendations will have to be executed
by a structural engineer however.
Tubular NDT Lifting & Inspection services
Inspection of oil well tubulars and rods, including but not limited to drill pipe, drill collars, well casing,
production tubing, sucker rods & risers.
Inspections carried out
Vessels, cargo & fuel oil tank inspections, plating, piping, flanges, lugs, umbilicals, derrick inspection and
drop surveys. Machinery mountings.
Crane & Lifting Inspection Services

Reporting will be to your specifications.
Methods of NDT
Inspection of materials, components, and assemblies is often required in order to determine if
they comply with design specifications or are defective. Of utmost concern for newly manufactured
or constructed items is their ability to withstand the mechanical stresses and chemical attack to
which they are expected to be exposed. For items that are already in service, the question is whether
or not the item will continue to function satisfactorily in its service environment until the next
NDT by virtue of its ability to detect flaws, measure dimensions, and assess material characteristics,
has become a primary tool in addressing the predictions of component performance and remaining service
life. The selection of an appropriate NDT method for a specific application is based upon the physical
characteristics of the material and the discontinuities of most interest, including the probable location,
orientation, size, and morphology. The assumption is that if an item is free from unacceptable flawed
conditions, it should meet performance expectations, that is, carry the load, withstand the vibration,
or maintain dimensional integrity
The NDT approach to materials testing is non-destructive in that each inspected item is expected to be
placed in service. This is in stark contrast to the destructive methods of materials evaluation where
sacrificial specimens are required. In destructive testing, specially prepared specimens are stressed
in a manner that simulates the stresses to which the item may be subjected and at levels exceeding the
design limits. The destructive approach results in specimens fracture, distortion, or some other form
of degradation, and thus is applied on only a sampled basis.
NDT is most commonly used where component failure may have catastrophic consequences, such as in aircraft,
electric power plants and petrochemical plants, as well as gas lines and offshore installations. The
periodic inspection of components in these fields determines if they are suitable for continued service.
The advantages of NDT for in service applications include safety evaluation with a minimum of system
down time, early detection of potentially dangerous and costly unscheduled service interruption and the
ability to monitor degradation processes from which realistic and cost effective re-inspection schedules
can be developed.
