Two decades of benchmark EMAT technology performance. Now taken further.
Based on electromagnetic acoustic transducer (EMAT) technology, RoCD EMAT-C has been the benchmark service for reliable crack detection in gas pipelines for more than 20 years. Operators around the world rely on its proven performance and acknowledge its significant contribution to safe and efficient pipeline operation.
Building on a proven track record in the field, strengthened through continuous development, RoCD EMAT-C Ultra represents the next evolution in EMAT pipeline inspection, introducing a step change in how crack-related threats can be identified, characterized, and managed.
A step change in crack detection and characterization
RoCD EMAT-C Ultra fundamentally enhances the way inspection data is acquired and interpreted.
With
- Doubled sensor coverage, and
- Clockwise and counterclockwise scanning,
each crack indication in the pipe body and long-seam is captured from two independent directions.
This generates a new level of available information from two directions at any given location in the pipeline, creating a new level of data density and data quality for an outstanding identification and characterization of crack-related threats in gas pipelines.

The dual-direction inspection concept generates substantially richer datasets. This data foundation enables a new analytics concept, directly supporting:
- Improved Probability of Detection (POD)
- Improved Probability of Measurement Independence (POMI)
As a result, operators gain:
- More accurate threat prioritization
- Clearer distinction between critical and non-critical crack indications
This supports confident, defensible integrity decisions.
The enhanced data quality and analytics capability of RoCD EMAT-C Ultra translate directly into faster reporting.
This reduces the time from inspection to action, enabling operators to
- Focus on preventing failures
- Minimize unnecessary excavations
- Optimize maintenance and repair planning.
The result is improved operational efficiency without compromising safety.
Designed to integrate seamlessly into existing operational workflows, this evolved EMAT technology ensures operators benefit from substantial performance enhancements while maintaining familiar inspection processes, interfaces, and integrity management practices.
No disruption. No reinvention of proven workflows.
ROSEN’s EMAT-C Ultra inspection service is engineered specifically for the operational conditions of gas pipelines.
