High-Accuracy Inspection for Pipeline Integrity and Corrosion Control
At PT Saka Nusa Persada, we provide professional Close Interval Potential Survey (CIPS) and Direct Current Voltage Gradient (DCVG) services designed to ensure your cathodic protection system operates at optimal performance.
Combining advanced technology with certified field specialists, we help oil & gas operators detect early signs of corrosion, minimize pipeline failure risks, and maintain long-term asset reliability.
Why CIPS & DCVG Are Essential
Underground pipelines are constantly exposed to soil conditions that promote corrosion. CIPS and DCVG surveys are critical components of any Pipeline Integrity Management Program, allowing operators to:
- Detect coating defects or damages
- Evaluate cathodic protection (CP) effectiveness
- Identify corrosion-prone zones and anomalies
- Support coating rehabilitation and repair decisions
- Prevent system failures and costly shutdowns
Routine CIPS & DCVG inspections help ensure that your pipeline operates safely, efficiently, and in compliance with NACE, ISO, and ASME standards.
CIPS – Close Interval Potential Survey
The CIPS method measures the potential difference between the pipeline and the surrounding soil along the pipeline route.
Benefits of CIPS
- Real-time monitoring of cathodic protection performance
- Identification of under-protected and over-protected zones
- Accurate mapping of potential gradients to locate active corrosion areas
- Actionable data to support integrity assessments
Why Choose PT Saka Nusa Persada for CIPS
- Ultra-high precision measurements at close intervals (1–2 meters)
- Internationally calibrated instruments and advanced data loggers
- Experienced technicians in both onshore and remote environments
- Comprehensive technical reporting with corrective recommendations
DCVG – Direct Current Voltage Gradient
The DCVG technique locates and quantifies coating defects on buried pipelines by measuring voltage gradients on the soil surface.
DCVG Advantages
- Accurately locate coating holidays and disbondments
- Assess the severity (magnitude) of each coating defect
- Reduce rehabilitation cost through precise repair targeting
- Evaluate coating performance relative to cathodic protection systems
Our DCVG Service Advantages
- Precise location and severity classification of coating damage
- Integrated analysis with CIPS data for complete integrity assessment
- Digital GIS mapping for long-term integrity records
- Field reports ready for SKK Migas or corporate compliance submission
