TSC Subsea, a UK-based provider of remotely deployed subsea inspections, has successfully secured a multi-year contract in Brazil. The agreement involves subsea phased array (SPA) inspection of circumferential welds on rigid subsea pipelines, including both flowline and riser sections, at depths of up to 3,000 meters. The contract, which will run from 2025 to 2027, calls for continuous weld inspection services using phased array ultrasonics (PAUT) specifically adapted for ultra-deepwater conditions.
The PAUT technology, which is well-regarded for its crack detection and defect sizing capabilities in topside applications, has now been integrated with TSC Subsea’s deepwater robotic systems to support non-destructive testing (NDT) of critical subsea assets. This advanced inspection solution aims to enhance the safety and reliability of subsea infrastructure at extreme depths.
“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’re proud to support our client with consistent, repeatable weld inspection services that meet the highest industry standards.”
The qualification process for the contract included multiple factory acceptance tests (FATs), scanner trials in pressure chambers, and inspections of 10 and 12-inch coated test samples featuring embedded defects. According to TSC Subsea, this rigorous qualification process ensures the effectiveness and dependability of their subsea inspection services.
“This award further validates how our remotely deployed robotic solutions enable accurate and dependable subsea asset integrity assessments,” the company stated in a social media post. “With world-class NDT 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.”
In a separate achievement, TSC Subsea secured another multi-year contract in July 2024 with an undisclosed operator to deliver subsea inspection services for insulated flexible pipes in Brazil’s pre-salt region.
The company’s continued success in securing significant subsea contracts underscores its leadership in the field of subsea inspections, offering cutting-edge technology and expertise to ensure the integrity of subsea infrastructure in the most challenging environments.
