Real-time detection of damage to pipelines caused by excavators

In order to protect pipelines from damage (e.g. during construction activities), they are regularly inspected on foot, from a vehicle or helicopter. Practical experience has shown, however, that these methods do not ensure continuous and comprehensive monitoring. PipeMon+® closes this gap, allowing appropriate measures to be taken immediately when a pipeline is suddenly damaged.

Concept

  • OGE has developed a pipeline monitoring method based on the principle of cathodic protection (CP)
  • When a cathodically protected pipeline is damaged by construction equipment (excavator, drill, rotary cultivator, etc.), the protective current distribution on the pipeline changes
  • Using appropriate sensors and special analysis methods, these events can be detected in real time

Approach

  • Sensors are installed approx. every 20 kilometres along the pipeline (network-independent power supply via marker posts with solar panels)
  • Sensors continuously measure current and potential (10 times per second)
  • If there is contact between an excavator and the pipeline, the operating personnel are alerted
  • A pipeline operations team member may be scheduled to site to check the reported excavator contact

Areas of Application

  • Temporarily during construction work and when new loop line is constructed
  • Permanent for selected networks (e.g. areas with very high protection requirements)

Benefits

  • Protection of man and the environment
  • Protection of asset and security of supply
  • Compensation by party that has caused the damage
  • Low investment costs due to use of existing infrastructure
  • Additional information on the condition and effectiveness of the cathodic protection (CP) system of the monitored pipeline
  • Extended CP monitoring intervals

Effective corrosion protection: Keep your pipes rust-free.

Corrosion protection is extremely important for natural gas pipelines to ensure the commercial viability and longevity of the system. Make use of the corrosion protection services from the German leader in this field of competence.

Are your gas installations and above-ground piping leak-free? GasCam® will tell you. 

Installations carrying gas are checked regularly for tightness. These checks previously involved probe measurements – which was labour and cost-intensive. We have developed a better process: remote gas detection based on infrared radio spectrometry.

The faster way to find pipeline leaks. And it works like a CHARM®. 

Detecting leaks in gas pipelines previously required walking along the pipeline with hand-held gas detection devices. This laborious process is now a thing of the past, since OGE now has CHARM®. CHARM® is a laser-based system integrated into a helicopter that flies along the pipeline while the system scans the pipeline corridor and identifies even the tiniest gas leaks.
