Hydrophone applications

Noise level monitoring

Hydrophone
KONGSBERG's hydrophone.

Renewables and oil & gas installations make underwater noise. Examples are construction noise from piling during installation of wind farms or noise from operation of airgun arrays during seismic operations. Such operations can generate noise at levels that may harm fish and marine mammals like whales and seals. KONGSBERG has developed hydrophone for monitoring of background noise prior to development and noise level during construction and operation.

Underwater Sound detection / monitoring.

Subsea gas leakage can be passively detected by the use of hydrophone arrays on the seabed.

Such leakages can be natural seepage of CO2 or Methane from the seabed. The hydrophones may also be used when looking for leakage from subsea gas reservoirs, production units and pipelines.

Marine mammals like whales can be detected by hydrophones picking up the sound of vocalization from mammals.

This is used both for marine science and also useful as a tool for detection of mammals prior to the start of an offshore application such as Seismic or similar operations where the operator must be able to identify that mammals are not present within the specific area.

The KONGSBERG RUNES hydrophone buoy is used in applications for noise level monitoring in offshore renewable as well as other underwater sound recordings. KONGSBERG has a skilled team specialised for underwater sound and noise monitoring that offers services related to the use of hydrophone solutions.

KONGSBERG's technical experts select a hydrophone with the right characteristics for the specific application. This would be a KONGSBERG or third party hydrophone, depending on the requirements
