Subsea NDT for Oil and Gas

Subsea pipeline inspections require the highest level of accuracy to produce high-quality, dependable inspection data. The pipeline’s integrity depends on it. TSC Subsea ARTEMIS and the vCompact™, incorporating TSC Subsea’s industry-leading Acoustic Resonance Technology (ART) or Subsea Pulsed Eddy Current Testing Array (SPECTA™), offer unique solutions for inspecting subsea pipelines, unpiggable pipes, flowlines, risers, and jumpers.

With the capability to conduct wall thickness measurement inspections even through paint, thick attenuative coatings, and soft marine growth while maintaining exceptional accuracy and eliminating the need for radioactive sources, TSC Subsea is the preferred NDT inspection service provider for many major operators.

Examining subsea structures, including assessing their structural welds, is paramount in maintaining the integrity of oil and gas production activities. The complex nature of subsea structures means inspecting these assets can be challenging, expensive, and even dangerous, especially with traditional diver-assisted inspections.

With a wealth of experience, TSC Subsea has effectively executed numerous inspections utilising various NDT technologies on critical welds within subsea structures using a variety of our subsea robotic solutions, including the MagCrawler™ and NodeScanner™.

Being a DNV-approved service supplier for Alternating Current Field Measurement (ACFM®) for Offshore Projects and Offshore Units/Components demonstrates our competence and expertise.

Regular inspections of the FPSO hull and bilge welds are crucial to identify cracks and defects resulting from dynamic loading.
TSC Subsea’s advanced Alternating Current Field Measurement (ACFM®) electromagnetic inspection technology combined with the MagCrawler™ can support underwater inspections instead of drydock (UWILD) inspection campaigns by safely detecting and sizing subsea surface-breaking cracks in critical welds such as bilge keels while the vessel remains in service.
