Consulting Engineering

Whilst we are happy to provide straightforward Inspection Services, we are often confronted with situations where our customers are faced with challenges in executing their inspection work program. Such situations usually require a fundamental understanding of engineering design, so that load conditions and likely failure modes can be fully assessed before the optimum inspection approach can be devised. To support this need, we employ a range of engineers, metallurgists and physicists; many of whom are qualified to BSc, MSc and PhD levels.

Calibration & Repairs

We recommend that calibration of our equipment is checked annually. We offer a calibration service at designated locations around the world, so that we can accommodate our customers’ needs and minimise their equipment downtime.

Each instrument is stripped down and fully inspected for any tell-tale signs of potential damage or excessive wear and tear. Critical system tolerance settings are checked and software configuration files are adjusted as necessary. Suspect components are repaired or replaced.

When our technicians are confident that everything is in order, equipment is carefully reassembled and fully tested on metallic components with known defects, so that we can be sure everything is in working order and issue a new certificate of conformity.

Training & Competence


Our in-house training scheme is conducted in accordance with the American Society for Non-destructive Testing recommended practice SNT-TC-1A. Unlike other recognised schemes, we can provide training in our own offices or at our customers’ sites, thereby minimising cost, disruption and lost travel time for employees.

SNT-TC-1A is an employer-based scheme, requiring the employer to have a Company Written Practice that is administered by a Level 3 qualified practitioner. We run SNT-TC-1A courses in ACFM® for Levels 1 and 2, which are administered by our own Level 2 or 3 qualified personnel, who are also certified to PCN or CSWIP.

Our standard courses cover the inspection of welds, which takes five days per level. In addition to SNT-TC-1A certified courses, we occasionally create and deliver bespoke courses in special NDT applications. One example is our thread inspection course, which covers the inspection of threaded connections used in the drilling industry.

Some industries require independent certification, such as CSWIP and PCN, which are individual schemes that comply with EN473. TSC has supported the development of these independent schemes and courses are available in the USA, South East Asia and the UK. These are delivered by independent training providers such as The Welding Institute and Lavender International.

Competence Assessment

During the past 20 years, a substantial number of people have passed Levels 1 and 2 examinations in the use of ACFM® NDT methods. However, a number of customers have expressed concern that, whilst folks may have passed the examinations, they may not have recent operating experience of using the equipment and may therefore not be competent in its use.

We therefore offer a one-day program for qualified operators who are taken through a familiarisation program to refresh their knowledge on ACFM®. We then run a set of strict tests to ensure that the operator is fully aware of what to expect on the job. These tests are conducted in simulated real life environments, on full-size structural joints and components with known defects, where the operator has to communicate remotely with our diver using the same technology as used offshore.

The test program has been developed by our own Level 3 qualified engineers who also have several years’ experience of executing NDT programs in challenging conditions.
