Integrity Management on TAPS
Leak Detection

Alyeska has a network of monitoring systems that rely on two basic elements for detecting leaks on the pipeline: on-line leak detection and visual observation. The TAPS on-line leak detection systems provide early notification of potential pipeline leaks. They are composed of three independent systems: deviation alarms for pressure and flow rate; line volume balance; and transient volume balance. To minimize environmental damage, each network capitalizes on unique leak characteristics to detect leaks as early as technologically possible. Visual observation includes regular air and ground field surveillance along the pipeline route. If a major leak should occur, valves along the pipeline limit the amount of oil that could leak from any section of the line.
