WHAT IS SPECTRUM XLI?

XLI, a complete system to collect multiple sources of data in a SINGLE run for the inspection of buried pipelines.

Simultaneously, the system can collect: GPS/GIS, depth of cover, gas leak detection, cathodic protection survey (CP CIPS/CIS), direct current voltage gradient (DCVG), alternating current voltage gradient (ACVG), alternating current-current attenuation (ACCA/CAT) and soil corrosivity measurements.

XLI CONTINUOUSLY RECORDS – AUTO / MANUAL

THE XLI ADVANTAGE

In a Single Pass, XLI simultaneously and continuously records

Sub-meter DGPS at 1 time per second (1 htz)

ACCA / CAT, DoC at 7 times per second (7 htz)

CIPS, DCVG and ACVG at 35 times per second (35 htz)

Encrypted data is Traceable and Auditable as raw logs also supplied to pipeline owner

Surveyor’s movement is continuously recorded providing Authenticity of data collected

Surveyor concerns in Field are automatically highlighted in XLI Office providing Transparency

Auto-Integration of multiple surveys as being performed at same time

Surveyor provided with Real time information and can take immediate action

while surveying (as raw logs visible to Surveyor on XLI Field PDA)

Finally, true survey data with corrected erroneous readings (if required) provided to pipeline owner. Any Corrections made are Traceable to Pipeline Owner.

“Time is money and to eliminate the human error, the XLI system was built to record simultaneously multiple survey data directly for accuracy and reliability”

Spectrum XLIA complete system for above-ground pipeline inspections

What is Spectrum XLI?Spectrum XLI is a complete system for proactive above ground inspection of buried pipelines. Unlike conventional above ground inspection tools – which often collect only a single data source in each pass – the XLI system collects multiple sources of data in a single pass.

Simultaneously, the system can collect: GPS/GIS, depth of cover, depth of water, gas leak detection, cathodic protection survey (CP CIPS/CIS), direct current voltage gradient (DCVG), alternating current voltage gradient (ACVG), alternating current-current attenuation (ACCA), and soil corrosivity measurements.

It can be used for the following inspections: External Corrosion Direct Assessment (ECDA), Internal Corrosion Direct Assessment (ICDA), Stress Corrosion Cracking Direct Assessment (SCCDA), Cathodic Protection (CP) and Close Internal Surveys (CIS).

How does it work?Inspections are completed by field teams that walk the pipeline ROW recording the desired pipeline data with the Spectrum XLI equipment. All measurements are logged into secured encrypted raw logs, which ensures that data cannot be adulterated. The complete raw data log can be audited upon the pipeline owner’s request.

Post analysis and reporting of inspection results is completed by NACE certified CP and Corrosion Specialists, ensuring that reliable pipeline integrity recommendations are made. All project deliverables are completed and delivered quickly after the inspection, unlike traditional, single-technology platforms, which provide deliverables at different times in different vendor formats.

When to use the technology?Spectrum XLI should be used to identify potential areas of corrosion on buried pipelines before they occur. Because the system can collect multiple sources of data in a single pass, it should be used to reduce risk and create cost efficiencies within an above-ground inspection program that requires multiple surveys.

In single inspection above-ground surveys, Spectrum XLI offers more reliability than traditional single-inspection systems, since all measurements are logged in a secure encrypted raw log and can be audited by a third party.

Why use Spectrum XLI?Spectrum XLI is the only indirect inspection technology that can be customized to meet client’s inspection needs by completing a combination surveys in a single pass. This reduces the risk and cost of collecting above-ground pipeline data by reducing the number of passes needed to collect that data.

The system also collects quality, auditable data that can be verified by the pipeline operator. This data eliminates guess work, and allows the pipeline owner to make defensible pipeline integrity and repair decisions.
