CASING AND TUBING
Our multiple inspection techniques provide valuable inspection data where casing or tubing integrity is critical to a wellbore.
Casing is the major structural component of a well. Proper inspections are critical to ensure safe drilling and production programs, and optimization of your casing or tubing strings.
New or used Casing and Tubing inspection services includes:
EMI inspection, API full length drift, visual thread, UT weld inspection, hardness testing, bucking, I.D./O.D. cleaning, thread gauging and dimensional measurements.
The type of Riser System employed in the Oil & Gas operations offers specific and often critical challenges.
We provide comprehensive services throughout the life cycle of the riser.

SPECIALITY INSPECTION SERVICES
NON-DESTRUCTIVE TESTING (NDT)
Inspections are critical points in the lifecycle of an asset and are needed to ensure they remain safe and do not become the cause of an avoidable expense.
A scheduled shutdown period to perform intrusive inspections can cause a major disruption to operations.
Well planned and executed NDT delivers valuable data about the condition of the asset and avoids unnecessary stoppages, without compromising safety.
We ensure our inspectors are trained and qualified to the highest local or international standards.
NDT inspection can be performed offshore, in subsea, difficult to access or “at height” locations.
Whatever the location the inspector will be using the most practical and appropriate inspection techniques, to an inspection scheme tailored to the specific area and equipment.
New techniques are continuously being evaluated to establish their value and usefulness to our clients.

LIFTING EQUIPMENT INSPECTION AND MANAGEMENT SYSTEM
The safety and reliability of a lifting appliance or lifting gear cannot be ensured unless it has received regular inspections.
Regular inspections are particularly important because they provide a useful means of detecting potential hazards which could contribute to accidents.
Regular inspections can also forewarn the owner of necessary preventive maintenance or repair, the lack of which can lead to serious deterioration of the lifting appliance and expensive replacement or repair charges.
An inspection means a visual and physical checking usually supplemented by a functional check to examine the states of individual items of a lifting appliance or lifting gear.
The purpose of an inspection is to find out whether there is any item having abnormal wear and tear, malfunction, oil leakage, overheating, corrosion, unusual noise, dislocation, visual cracks, misalignment, overloading, abnormal slackening or elongation, and excessive vibration, etc. and if necessary to arrange for subsequent remedial actions such as repair and replacement of the defective parts, or to stop the lifting appliance or lifting gear from further use if a critical condition exists.
A thorough examination should cover those components of lifting appliances and lifting gear which are subjected to certain degree of exposure to wear, deterioration, malfunctioning or misalignment. Lifting appliances and lifting gear should be carefully examined to identify any deficiencies that may constitute a hazard.
To ensure that the lifting appliance or lifting gear is safe to be used, a thorough examination not limited to the following should be conducted:
- Visual examination;
- Dimensional examination;
- Functional or operational test;
- Open-up examination;
- Electrical test and examination;
- Non-destructive test.
At TECSEP we follow the most stringent standards and procedures (DNV, EN and API) for the Inspection of Lifting Equipment and also recommendations and regulations (LOLER, LEEA) to provide the best in quality services to the Angolan Oil Industry. Our lifting equipment Management systems ensure that every single item used in lifting in our client base is captured and managed via our system for Inspection, certification and maintenance to guarantee the safety of these at any time.
