What types of non-destructive testing (NDT) and tubular inspection methods are utilized?
OGTC deploys advanced inspection techniques tailored for drilling assets, including electromagnetic inspection of drill strings, magnetic particle inspection, liquid penetrant testing, ultrasonic inspection, and hardness testing. These methods ensure drill pipes, BHA tools, casing, and tubing meet rigorous industry standards.
Are your inspection and testing services compliant with international oil and field standards?
Yes. OGTC’s operations and technical teams adhere strictly to recognized global standards and maintain affiliations with major bodies such as the American Society for Nondestructive Testing (ASNT) and the International Association of Drilling Contractors (IADC) to guarantee maximum safety and quality assurance.
Rig & Tubular Inspection
What types of rigs and rig equipment do you inspect?
We inspect drilling rigs and associated equipment, including masts, substructures, lifting equipment, handling tools, and other critical components. The inspection scope is agreed according to the equipment, client requirements, and applicable standards.
What tubular and OCTG inspection services do you offer?
We inspect drill pipe, heavy-weight drill pipe, drill collars, bottom-hole assembly components, casing, and tubing. Services may include visual inspection, dimensional checks, wall-thickness measurement, drift testing, and non-destructive testing, depending on the agreed scope.
What is non-destructive testing (NDT)?
NDT examines materials and components for defects without damaging them. Depending on the material and inspection requirements, OGTC provides methods such as magnetic particle inspection, dye penetrant testing, ultrasonic testing, and electromagnetic inspection.
Do you inspect and test pressure and temperature equipment?
Yes. OGTC provides inspection, testing, and calibration services for pressure and temperature equipment. The required service depends on the equipment’s function, condition, operating range, and applicable requirements.
Calibration
Which instruments and equipment can OGTC calibrate?
We provide calibration services for pressure instruments, temperature instruments, and other measuring equipment, as well as medical equipment within our supported scope. Please share the equipment type, make, model, and measuring range so we can confirm the appropriate service.
Why is instrument calibration necessary?
Calibration checks an instrument’s readings against a suitable reference to determine measurement accuracy. It supports reliable operation, quality control, and compliance with applicable requirements.
What is the typical turnaround time for calibration services?
Turnaround times depend on the specific type, quantity, and complexity of the instruments, as well as whether any adjustments or repairs are required upon testing. Once OGTC receives equipment details or items at its facility, an estimated completion schedule is provided to ensure minimal downtime for client operations.
Do you provide calibration certificates and traceability records?
Yes. Every calibrated instrument is accompanied by a comprehensive calibration certificate detailing the measurement results, uncertainty, and environmental conditions during the test. OGTC maintains traceability to national and international measurement standards to meet strict quality assurance and audit requirements.
Surveys & Audits
What is a DROPS survey?
A Dropped Object Prevention Scheme (DROPS) survey identifies items that could fall from height and cause injury or equipment damage. It examines equipment securing arrangements, secondary retention, and potential dropped-object hazards, with findings and recommended corrective actions recorded in a report.
What do your electrical surveys cover?
Electrical surveys assess the condition and safety of electrical installations and equipment. Depending on the agreed scope, they may include visual checks of wiring, connections, enclosures, earthing arrangements, and equipment suitability for the operating environment.
What do your mechanical surveys cover?
Mechanical surveys assess equipment condition and identify visible defects, wear, damage, and maintenance concerns. The survey scope is tailored to the machinery, facility, and operational requirements.
What types of audits does OGTC offer?
OGTC conducts technical and equipment-related audits against agreed requirements. These audits help identify gaps in equipment condition, inspection records, maintenance practices, and operational compliance.
Standards & Reporting
Which standards do you follow?
OGTC performs services against applicable standards, manufacturer requirements, and client specifications agreed for each job. These may include relevant API, DS-1, ASME, EN, and ISO requirements, depending on the equipment and service.
Will we receive a report or calibration certificate?
Yes. Documentation is issued according to the completed service and agreed scope. This may include inspection reports, test results, calibration certificates, survey findings, and recommendations for corrective action.
How often should equipment be inspected or calibrated?
Intervals depend on the equipment type, usage, operating conditions, manufacturer guidance, applicable requirements, and previous results. OGTC can help clients establish suitable inspection and calibration schedules.
On-Site & Commercial
Can inspections and calibration be performed at our site?
On-site services can be arranged where the equipment, service scope, and site conditions allow. Some activities may require a controlled workshop or laboratory environment. We confirm these arrangements before the work begins.
Can OGTC support urgent jobs or shutdown activities?
Urgent inspections and shutdown support can be arranged subject to personnel, equipment availability, and site access. Please provide the scope and required completion date so we can confirm mobilization.
How can we request a quotation?
Share the service required, equipment list, quantities, specifications, location, and preferred schedule. For calibration, include the instrument make, model, measuring range, and required accuracy where available. OGTC will review the details and provide a quotation.
