Sercel Underwater Acoustics (ex Orca Instrumentation) develops and markets underwater data transmission systems and marine instrumentation for oceanographic engineering, scientific community, military and oil & gas applications.
The company's products include underwater acoustic communication & positioning systems, passive acoustic monitoring & marine mammal detection systems, ocean bottom seismometers, mooring monitoring beacons, acoustic transducers & hydrophones.
You will find below a description of the products designed by Sercel Underwater Acoustics:
MATS 3G ACOUSTIC MODEM
MATS 3G is an underwater acoustic modem that offers a single solution for all underwater communication needs. Its state-of-the-art DSP (Digital Signal Processing) technology ensures long-range and reliable communication.
MATS 3G is ideal for AUV (Autonomous Underwater Vehicle) communication. As well as being compact and light, it has a high data-rate link, which can be used to transfer images from a subsea camera or side-scan sonar data to a master vessel at the surface. When deployed in an offshore drilling platform environment, it provides an error-free underwater communication solution to command subsea valve operations.
MATS 3G’s use can range from oceanographic applications to real-time monitoring by networked stations across vast instrumented fields.

QUIETSEA PASSIVE MONITORING
QuietSea’s passive acoustic monitoring (PAM) system is designed to detect the presence of marine mammals during offshore operations.
QuietSea provides high marine mammal detection capabilities in a wide frequency listening range that covers a large variety of vocalizing cetacean species. QuietSea is particularly adapted to civil engineering projects where marine construction activities are likely to produce underwater noise and vibration levels capable of causing injury and disturbance to marine mammals. QuietSea provides appropriate monitoring and mitigation measures of marine life and allows to protect mammals during marine operations. For environmentally responsible operations, QuietSea complies with the increasingly widespread marine mammals monitoring regulations worldwide.

GEOTAG UNDERWATER POSITIONING
GeoTag is an acoustic positioning system that has been designed to work with any ocean bottom or transition zone seismic equipment down to 500 meters deep. GeoTag is the smallest acoustic transponder on the market, allowing flexible and cost effective operations due to its ability to be stored on a reel and deployed by mechanical squirter.
GeoTag can be deployed for shallow and deep surveys. Up to 10,000 transponders can be used per system.
GeoTag benefits from Sercel’s expertise in advanced acoustic technologies to provide a reliable state-of-the-art turnkey solution for your acoustic positioning needs.

MicrOBS is an autonomous deep 4C ocean bottom seismometer that dives as far as 6000m down to the sea floor by itself. Integrating a combination of 3-C low distortion geophones plus a hydrophone, it records P-S waves up to 24 days.
At any time, by sending a specific signal from the vessel, MicrObs releases its anchor to get up to the surface. Sending a radio signal and activating a flashlight, it is retrieved easily to download its data.
Designed for deep-water refraction seismic surveys, MicrOBS provides excellent refractor arrivals from crustal discontinuities. With 4C multi-component recording, MicrOBS can allow accurate characterization of P & S velocities in deep crustal layers.
MicrOBS is also used to record and monitor earthquakes and natural seismicity to determine epicentre and associated mechanisms in active tectonic areas.

BASM/BABS MOORING MONITORING
Designed to retrieve a buoy in case of mooring line break, BABS warns owners of line breakage by transmitting a signal to ARGOS satellites while BASM alerts of underwater equipment that may surface by transmitting through the same ARGOS satellite system.
