TSC Subsea

TSC Subsea provides subsea non-destructive testing (NDT) inspection services for offshore assets, using patented and proprietary inspection technologies combined with remote robotic systems. Its core work assesses the integrity of subsea infrastructure such as pipelines, flexible and rigid risers, offshore structures, vessels, and FPSOs, with deployment by remotely operated vehicles (ROVs), divers, and diverless robotic scanners and crawlers. The company specialises in advanced subsea robotic inspection, combining multiple NDT methods with custom robotic delivery systems to obtain reliable data from difficult or hazardous environments. TSC Subsea serves markets including oil and gas, offshore wind, maritime and shipping, and flow assurance. Its applications cover flexible risers, subsea pipelines, subsea structures, vessels, FPSOs, grouting, splash zone work, flooded member detection, unpiggable pipelines, and underwater hull inspection. It performs integrity assessments and inspection campaigns that support engineering decisions, life extension, and operational planning. Its work covers a wide range of water depths, from the splash zone down to ultra-deepwater, and it draws on experience with offshore assets already in service rather than only with new construction. The inspection scope includes validation of in-line inspection surveys, measurement of corrosion and erosion, detection and sizing of weld defects and surface-breaking cracks, corrosion-under-insulation assessment, pipeline geometry measurement such as ovality and dents, corrosion mapping, wall-thickness measurement on elbows and extrados areas, hydrate detection, grout integrity evaluation, flooded annulus identification in flexible risers, and FPSO hull surveys. Advanced NDT methods in use include ACFM, ART, PEC, SPA, and ToFD, integrated with robotic platforms such as ARTEMIS, ORCA, MagCrawler, NodeScanner, vCompact, Triton, LinearScanner, vCaliper, ART Guide, vPush, LineScanner, ExtradosScanner, and DexScanner. A distinctive feature of the business is its ability to combine these techniques into remotely deployed, often diverless solutions that reduce cost, environmental impact, and risk to personnel while improving inspection speed and data quality, so an operator can establish the condition of a riser, a pipeline, or a hull without putting divers in the water.
