TSC Subsea secures multi-year ultra-deepwater weld inspection contract in Brazil
22/07/2025
TSC Subsea has announced that it has secured another multi-year contract in Brazil with a leading operator for subsea phased array inspection of circumferential welds on rigid subsea pipelines. The scope includes both flowline and riser sections at depths reaching 3000 m (10,000 ft). The contract, running from 2025 to 2027, will ensure the delivery of continuous subsea inspection services throughout the term.
Phased array ultrasonic testing (PAUT) is widely recognised for its effectiveness in topside weld inspection and its accuracy in detecting and sizing cracks and defects. TSC Subsea has now adapted this proven technique for ultra-deepwater environments, helping ensure the integrity of these critical subsea assets.
Combined with the company’s advanced robotic systems, purpose built for ultra-deepwater operations, it delivers a highly reliable non-destructive testing (NDT) solution for weld integrity assessments.
“Having demonstrated the strength of our advanced NDT solution, proven to be the most reliable and efficient, this contract stands as a strong vote of confidence in our team, our technology and our capability to perform in the most challenging subsea environments,” said David Melo, Sales Manager at TSC Subsea. “We are proud to support our client with consistent, repeatable weld inspection services that meet the highest industry standards.”

The rigorous qualification process involved multiple factory acceptance tests (FATs) and approval stages, including technology and scanner trials in a pressure chamber to simulate ultra-deepwater conditions, as well as 10- and 12-inch test samples, each with multiple hidden defects, which were covered by DNVGL-RP-F102 pipeline field joint coating.
TSC Subsea has made significant investments in Brazil over the years, building a strong presence in the region with a focus on developing the best local talent. That commitment is now paying off, with local expertise and infrastructure playing a key role in securing and delivering this contract.
This award further validates how TSC Subsea’s remotely deployed robotic solutions enable accurate and dependable subsea asset integrity assessments. With world-class non-destructive testing technologies, advanced robotic scanners and a highly experienced team of NDT specialists, TSC Subsea is leading the way in subsea inspection innovations, paving the way for safer and more sustainable operations across the industry.
