CARQUEFOU, France – Sercel has received approval from the UK Department for Business, Energy & Industrial Strategy and the Joint Nature Conservation Committee to deploy its QuietSea passive acoustic monitoring (PAM) system.

The equipment will be featured in a CGG seismic survey off the Shetland Islands.

QuietSea’s sensors are designed to integrate fully with seismic acquisition or navigation systems and are incorporated with the hydrophones in the Sentinel streamer.

By eliminating the need for deployment of separate PAM antennas at sea, Sercel claims, the system can cut the risk of accidents during deployment, retrieval, and operation.

Previously, the company extended the system’s frequency bandwidth to 180 kHz, allowing detection of porpoise click trains.
