Underwater
acoustic systems
We provide a wide range of underwater acoustic systems, for i.e. ultra low noise hydrophones, which are suitable both for oceanographic research and environmental monitoring.
Subsea leak
detection
Our mission is to provide the most effective leak detection systems and the most efficient leak detection service for the Oil & Gas offshore industry.
Custom systems
& services
We design and manufacture acoustic systems according to our customer needs: from a simple underwater hydrophone to multi channels arrays, complete of telemetry and processing units.
Geophysical
Surveys
We design innovative solutions to study the seafloor, the coast and inland waters with geophysical and morphology surveys.
Co.l.Mar Italia hydrophone technology
Colmar Italia: Experts in Hydrophones, Projectors, and Underwater Acoustics
For over forty years, Colmar Italia has specialized in underwater acoustics, offering advanced solutions in the design and production of hydrophones, underwater projectors, and acoustic transducers. Our acoustic systems are widely used in both civil applications—such as oceanographic research, environmental monitoring, and geophysical surveys—and military applications, including active sonar systems, passive acoustic sensors, and underwater antennas.
Colmar is also at the forefront of subsea leak detection for offshore oil and gas pipelines through our patented ALDⓇ technology, certified according to DNV standards. Our services are trusted by major oil companies worldwide.
Our headquarters houses Italy’s largest indoor acoustic testing pool (11m x 14m x 8m), purpose-built for hydrophone calibration, acoustic measurements, and underwater equipment testing.
