QuietSea Passive Acoustic Monitoring System set for GOM
Sercel's QuietSea™ Passive Acoustic Monitoring (PAM) system, which is seamlessly integrated into seismic streamers to detect the presence of marine mammals during seismic operations, has been authorised by the US Bureau of Safety and Environmental Enforcement (BSEE), for seismic survey operations in the US waters of the Gulf of Mexico.
BSEE recognises that the ability to use geophysical survey streamers for PAM is an effective future development of PAM systems.
In late 2016, QuietSea was deployed commercially for the first time, for nearly three months of continuous use, on a proprietary 3D seismic survey conducted offshore Morocco.
Sercel’s QuietSea marine mammal monitoring system was specifically designed to provide clear and accurate mammal detection and localisation information to PAM operators having to make rapid and well-informed decisions during seismic surveys.
An operator onboard CGG's Geo Caspian vessel used QuietSea during the night or at times of poor visibility. It also provided automatic mammal detection during the day, which complemented the regular visual sightings by the marine mammal observer.
Pascal Rouiller, Sercel CEO, said: “These two important milestones confirm the industry’s recognition of QuietSea as an effective marine mammal monitoring system for environmentally responsible marine seismic acquisition. Its accuracy and reliability, combined with its ease of deployment and user-friendliness, make it the ideal mitigation tool for optimising marine mammal detection while eliminating any potential related safety risks.”
