Non-Destructive Testing (NDT) involves detecting and assessing flaws in materials without causing damage. Vertech has proven experience in NDT inspection planning, advising clients on NDT services, and providing recommendations and solutions to ensure compliance to international and Australian standards.

Vertech Group are certified to ISO 17205 as an NDT inspection body by the National Association of Testing Authorities Accreditation Number is 18112. Our NDT inspection personnel are highly qualified, skilled and experienced in the application of a wide range of inspection and testing methods.

Our comprehensive range of conventional and advanced NDT services ensures our clients receive first class deliverables.

Conventional NDT Services

Safety, reliability, environmental requirements, and regulations all mean that companies across multiple sectors have a responsibility to maintain the integrity of their equipment. Vertech have a proven track record across the Asia Pacific region in the delivery of a wide array of conventional Non-Destructive Testing (NDT) methods from planning campaigns, advising clients on NDT methods, and providing recommendation & solutions to ensure code compliance to both international and Australian Standards.

Underpinned by specialist access and robotics, Vertech not only provides a base inspection service but can also manage the end-to-end solution from high mobility specialist access using rope access, engineered decking and netting systems through to deployment via ROV,UAV, or crawler deployed systems.

Specialised NDT Services

Sonomatic, our advanced inspection arm, is a leading provider of advanced NDT services to clients in a range of industries. Sonomatic brought innovation to the market by introducing Time of Flight Diffraction (TOFD) in the 1980s and has continued to bring world-leading technology to our clients. The team are unique among inspection service providers in that they develop their own inspection systems and scanners to meet specific requirements for inspection performance, deployment and in-field reliability.

Vertech has proven experience in a range of highly specialised advanced NDT services. All our NDT technicians are highly trained and have years of experience.

Vertech were engaged to complete a 100% structural inspection survey of an LNG loading jetty using specialist access systems. The inspection campaign included initial GVI screening of the structural members followed by CVI/NDT inspection. The data collected was used to construct a targeted Advanced NDT inspection scope which Vertech executed utilising Phased Array (wheel probe), LYFT (PEC) & TOFD corrosion mapping.


Vertech provided teams of multi-disciplined AICIP in service inspectors and NDT technicians to complete baseline inspections across 394 corrosion loops across the asset. Trailing the inspectors, we provided multi-disciplined rope access teams completing “find and fix” remediation to insulation also providing touch up coatings and STOPAQ application which reduced reportable items up to 50%.


Between 2015 and 2020 Vertech implemented its full range of conventional and advanced NDT services, In service inspection (ISI) and robotics services across three FPSO’s to conducted over 30,000 accredited inspections spanning pressure equipment ISI, vessel Hulls, cranes, lifting gear and other structures as part of our major services agreement with our customer.


In 2015 Vertech commenced baseline inspections of the Ichthys Venturer FPSO and the world’s largest semi-submersible, the Ichthys Explorer in South Korea. Continuing into operations in Australia Vertech now provides the full suite of specialist access, In service inspection (ISI), NDT, ROV and UAV services across the offshore assets and the Inpex LNG facility.


Vertech were engaged by Santos to provide a wide range of inspection services during the key Train 1 shutdown in 2019. Vertech successfully completed inspection of over 70 vessels and exchangers, using a combination of conventional NDT, in-service inspection (ISI), RDVI and advanced NDT inspection techniques.


In 2020 Vertech & Sonomatic screened 172 jetty piles with LYFT Pulsed Eddy (PEC) current The purpose was to determine the extent of external corrosion from the pile stock head to the water level (approximately 6m per pile). Vertech proposed and utilised the LYFT array probe (PECA) allowing the piles to be screened around the full circumference in only 4 scan strips, while still achieving a high level of data resolution. The inspection was completed on time, within budget and safely.
