Will the seismic activity have an impact on the environment?

Crogga is committed to minimising the impact of operations on the environment. Seismic surveys have been shown to only have short term, minor and temporary impact. A detailed Environmental Impact Assessment (EIA) has been carried out by international consultants which confirms this to be the case. The EIA will also enable us to time the survey for minimal impact on fisheries and fish stocks.

Natural gas developments are highly regulated and monitored but we plan to go beyond this. The Crogga survey will exceed (JNCC) Joint Nature Conservation Committee guidelines for seismic surveys. We will have Passive Acoustic Monitoring (PAM) and Marine Mammal observers onboard. In addition, the Crogga survey will use a lower power sound source than the majority of the previous surveys carried out in the Irish Sea.

We have also taken steps to ensure that the Crogga survey vessels will be fueled with low sulphur marine diesel reducing the atmospheric impact of the survey operations.
