Home Inspection & Instrumentation



All our inspectors have more than 5 years of field experience and are certified in various inspection methods, such as:

Our NDT inspection covers the following:

  •  Magnetic Particle Inspection
  • Liquid penetrant testing
  • Ultrasonic testing
  • Visual inspection
  • Training Syllabus covering Drill Stem Inspection in accordance with DS-1 and API RP 7G-2


For drill pipe inspection Black Lake uses New Tech Systems electromagnetic inspection units (EMI) with wall loss monitor. These units are capable of inspecting OD drill pipe ranging from 2 3/8″ up to 5 1/2″. In addition to tubular body inspection, thread inspection is carried out both visually and dimensionally for API and premium connections.


Bottom Hole Assembly (“BHA”) inspection consists of inspection of drill collars, heavy weight drill pipe, cross over subs, stabilisers, reamers and bit subs. The inspection of Bottom Hole Assemblies includes wet, fluorescent, magnetic particle inspection of threads and upset areas, and visual inspection of threads for mechanical damage and over torque. BHA inspections will conform to API RP 7G-2, T.H.Hill DS-1, or any other standards nominated by the customer.


We also offer the Magnetic Particle Inspection (MPI) of drilling rig mast, sub base, pipe elevators, slips, tongs, sheaves, welded areas of high-pressure lines and other hoisting and drilling equipment. Most of the above items are inspected, utilising A.C. Yoke magnetic flow technique.


Eddy current flaw detection is an NDT technique that can provide important time and cost savings as the rig structure does not require sandblasting prior to inspection.

The eddy current tool can be applied for various purposes, such as:

  • Crack detection
  • Material thickness measurement
  • Coating thickness measurement
  • Conductivity measurement for heat damage detection

Black Lake is a member of Lifting Equipment Engineers Association (LEEA UK). Our LEEA certified inspectors are cross-trained at ASNT Level II in all the inspection methods mentioned earlier.


The Black Lake Soft Tracking System analyses data about every piece of equipment on a client’s location that requires inspection and automatically provides recommendation for re-inspection dates. A customer receives an alert with suggested inspection dates and schedules the service date with Black Lake representatives. Black Lake team will monitor the client’s assets inspection expiry dates to ensure all the equipment on site remains inspected as per quality standards.


Instrumentation is a specialised oilfield service section for systems used on inland and offshore drilling and servicing rigs. We offer a tightly integrated package of services including installation, commissioning, on-site trouble shooting, remote support and both in-house and mobile calibration.
