CIPS & DCVG Survey Services for Underground Pipelines

CIPS & DCVG Survey Services for Underground Pipelines

Introduction

Underground pipelines are vulnerable to corrosion, coating degradation, and cathodic protection system failure. To ensure long-term integrity, safety, and compliance with international standards such as NACE SP0502, two advanced indirect inspection techniques are commonly applied: CIPS (Close Interval Potential Survey) and DCVG (Direct Current Voltage Gradient).

At KHMERNDT CO., LTD, we offer comprehensive CIPS and DCVG inspection services for buried pipelines and tanks. These methods help detect coating defects, assess cathodic protection performance, and locate areas of corrosion without excavation.

What is CIPS (Close Interval Potential Survey)?

CIPS is a detailed potential measurement technique that:

• Evaluates the effectiveness of the cathodic protection (CP) system

• Measures pipe-to-soil potentials at close intervals (1-2 meters apart)

• Helps determine if the pipeline is adequately protected from corrosion

• Complies with NACE SP0169 and other CP criteria

✅ Application: Oil & gas pipelines, water pipelines, buried tanks

What is DCVG (Direct Current Voltage Gradient)?

DCVG is used to locate and quantify coating defects by:

• Measuring voltage gradients in the soil over pipeline routes

• Identifying holidays, pinholes, and damaged coating areas

• Estimating defect size and severity for repair prioritization

✅ DCVG Benefits: Pinpoint defect location without excavation; reduce downtime and repair costs

Our Complete Service Includes

• Route survey and alignment mapping

• CIPS & DCVG survey by experienced engineers

• GPS data integration and defect reporting

• Coating condition analysis

• Final report with graphs, tables, and GIS mapping

🧪 All testing adheres to NACE, ISO, and client-specific standards.

Why Choose KHMERNDT?

• ✅ NACE-trained and certified technicians

• ✅ Advanced, calibrated field equipment

• ✅ Integrated reporting with GPS & GIS

• ✅ Fast turnaround and bilingual reports

CIPS គឺជាអ្វី?

CIPS គឺជាវិធីសាស្រ្តវាស់ potential ដែលមានភាពជិតស្និទ្ធ (ច្រើនធ្វើជារៀងរាល់ 1–2 ម៉ែត្រ) ដើម្បី៖

• វាស់កម្រិតបំពង់ទៅដី (pipe-to-soil potential)

• វាយតម្លៃប្រសិទ្ធភាពនៃប្រព័ន្ធការពារប្រឆាំងច្រេះ (Cathodic Protection)

• បញ្ជាក់ថាបំពង់មានការការពារពេញលេញទេឬអត់

• អនុវត្តតាមស្ដង់ដារ NACE SP0169

✅ អាចអនុវត្តបានសម្រាប់បំពង់ប្រេង បំពង់ទឹក និងធុងក្រោមដី

DCVG គឺជាអ្វី?

DCVG គឺជាវិធីសាស្ត្រប្រើសម្រាប់៖

• កំណត់ទីតាំងនិងទំហំកម្រិតសំណើមកើតឡើងលើ coating

• រកឃើញស្នាមបែក coating, holidays និង pinholes

• ធ្វើការវាយតម្លៃលើសភាពកម្លាំងអគ្គិសនីក្នុងដី

✅ អាចរកជុំវិញ defect ដោយមិនចាំបាច់ជីកដី, ប្រើប្រាស់សម្រាប់ការជួសជុលត្រឹមត្រូវ

HELIDECK INSPECTION

Helideck safety is critical to offshore and onshore operations in the oil & gas, marine, and energy sectors. Ensuring that a helideck complies with international safety standards is essential to protect personnel and assets. One of the most widely recognized standards is CAP 437, issued by the UK Civil Aviation Authority (CAA), which defines requirements for helideck design, construction, maintenance, and performance — including surface friction.
