ALD® Acoustic Leak Detector System Technology
ALD® acoustic leak detector is a patented technology of CO.L.MAR., which has benefited from the development of submarine inspection techniques and from the constant updating of equipment, in order to always work with cutting-edge tools and instruments. The ALD® service, including equipment and operators is supplied to promptly detect existing subsea leaks or, during pressure test of subsea installations, to guarantee an immediate inspection in case of pressure loss. ALD is an essential tool for pipeline integrity inspection and generally for IRM (inspection repair maintenance) activities.
Effectiveness: Not affected by current, turbidity, visibility, ambient noise
Sensitivity: Detected leaks as small as 0,04 lt/min
Reliability: 100% of success after 21 years on the field
Experience: 21 years operations, over 90 offshore projects and over 50 subsea leaks
Qualification: DNV-GL qualified technology
Rapidity: Fast worldwide mobilization
No need to stop production
ALD has detected leaks on buried pipelines, flanges, risers, umbilical, valves, gas leak, oil leak, water leak
The system is mainly composed by an underwater acoustic sensor, a POD (underwater electronic unit), a transmission line, a receiving unit and a PC based processing and display software. The sensor and the transmission line are different depending on the inspection techniques while the other components are common to all applications: while the sensor is driven along the pipeline or positioned close to a flange or connection, the receiver puts the operator in condition of identifying an eventual leak signal.
