Sensing element is a coaxially extruded silicone jacket element containing Carbon Black. Swells quickly by absorbing liquid hydrocarbons (crude oil or petroleum products).

Outer layer is watertight electrical insulator, permeable for liquid HC.

Inner layer is electrically conductive in normal status.

Internal Leak Detection System Characteristics

REAL LIFE FEED-BACK:

“Between 2002 and July 2012, remote sensors

detected only 5 percent of the nation's pipeline

spills.”

-- according to data (relating to 1,763 oil pipeline spills) from

the Pipeline and Hazardous Materials Safety Administration

(PHMSA)

Drawbacks : Must “catch” the leak event at the very beginning

A small leak progressively increasing (e.g. due to corrosion) will very likely not

be detected

Poor leak location - depending on positioning with respect to

pressure sensors In most cases, the precision is over 1km

False alarms

Reliability for multiphase products ?

Drawbacks :

Subject to false alarms – e.g. vibrations induced by engines, animals, …

Small leaks not detected

Calibration required Maintenance costs

Sensitivity is function of the distance (progressively decreasing)

In maintenance mode or power off or yet temporarily broken (for any reasons),

the system will fail to detect leaks after system integrity is restored

Spread-out of leaks cannot be detected

Focus on External Leak Eetection Technologies:OPTIC FIBRES : Optical Time Domain Reflectometry (ODTR)

Compared to other technologies, TTK sense cable stands out as a true « ZERO TOLERANCE » technology.
