The Acoustic Leak Monitor (ALM) is an application of Acoustic Leak Detector ALD® technology for the monitoring of subsea installations for leaks of any fluid (gas, oil, hydraulic oil, etc.).
The system has been designed to promptly detect leaks arising in the area surrounding the installation point. ALM is composed by a Subsea Unit (SSU) and a Top Side Unit (TPU) connected by a RS485/Ethernet link.

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.
