Data In Depth

In regular use in over 49 countries by the world’s petroleum and gas industries, the C-SCAN™ system evaluates the coating condition of buried transmission pipelines.

C-SCAN gives unrivalled measurements of depth of cover, coating quality and GPS position without physical contact with the pipeline. The non-contact measurement allows surveying over concrete, roads and water with equal accuracy

Pipeline Survey System

Detector

The C-SCAN detector uses a detailed display to give real-time data on the survey progress. Data includes distance to pipeline (Horizontal), Overhead location, Depth, Current and GPS position

GPS & Mapping

The C-SCAN 2010 System has a fully integrated GPS capability. The accurate position of every survey location can be recorded and displayed and will appear in the survey report. An external GPS unit may be attached.

Report Generation

Using the free program, DCAPP (PC only), all survey details can be downloaded and a report produced. DCAPP has tools such as distance filtering and upper and lower automatic defect analysis.

Coating Conductance

Using Dynalog’s proprietary algorithms, an estimation of the pipeline coating conductance can be calculated. Calculation relies on entering coating and soil characteristics.

About us

Dynalog Electronics

Since 1983, UK based company Dynalog Electronics has designed, developed and manufactured pipeline survey instrumentation. In regular use in over 49 countries by the world’s petroleum and gas industries, the C-SCAN system evaluates the coating condition of buried transmission pipelines. Using a patented antennae array, C-SCAN gives unrivalled measurements of depth of cover, coating quality and GPS position without physical contact with the pipeline. The non-contact measurement allows surveying over concrete, roads and water with equal accuracy.

The C-SCAN Current Attenuation methodology has been recognised by NACE as an approved method of coating evaluation for transmission pipelines under NACE RP0502 and NACE TM0102. With the included DCAPP program, detailed reports can be generated including pipeline position maps and coating conductance values. Dynalog has a continuing development program and regularly provides free software and firmware updates to all its products ensuring that the user benefits from improvements in operation.

What users say about C-SCAN

Chapman Engineering

White paper

'C-Scan scan can look at over 500 feet of coating in one shot and cover over 2 miles of pipe in one survey, Now that is efficient.'

Alireza Bahadori

Cathodic Corrosion Protection Systems: A Guide for Oil and Gas Industries

‘The C-Scan located the defects found by the Pearson survey and also located defects the Pearson survey did not find.’

Element Integrity Group Inc.

C-Scan is quality assurance that goes beyond visual inspection!

After burial was complete on this same project, C-Scan uncovered over 50 more anomalies. These anomalies were the result of mechanical damage during install/backfill and of poor coating application at the butt welds Read White Paper

Kemper Corrosion

...survey 20 miles per day

Kemper Corrosion has been using the C-Scan Pipeline Survey System for the past ten years. We have surveyed pipelines from North Dakota to Louisiana, New York to California. Many hundreds of miles of hydrocarbon and non-hydrocarbon pipeline, as well as a number of in-plant piping surveys have been completed successfully. Line diameters from 1”” to 48”, exhibiting a comprehensive cross section of coating applications, have been surveyed and, over time, all the functions available in the System have been employed. More recently a coating/depth of burial survey on approximately 300 miles of pipe resulted in the Client being very pleased with how well and how quickly the results were submitted. We have experienced rates of survey above 20 miles per day on well coated pipelines, and consistently above 10 miles per day on pre commissioned pipelines. We are pleased to report that, following the rapid identification of coating faults on new and rehabbed pipe, followed by check survey after the completion of repairs, the use of the C-Scan System has been written into the coating maintenance protocols of a major oil producing client in West Texas.
