What will the seismic vessels look like?

The typical vessel we will be using will be less than 100m in length. For comparison, the Steam Packet Company’s Ben My Chree passenger ferry is approximately 125m long. An example of a Seismic boat is shown belowREAD MORE

How are seismic surveys carried out?

In the case of the Crogga field, the seismic work will be conducted by a boat which will criss-cross the licence area over a number of weeks, sending and receiving sound waves to and from the seabed and below. When conducting the seismic over the license area, the vessels will be towing an array of hydrophones to collect the signal from an acoustic source on board the boat. The acoustic source will send sound waves through the water and underlying rocks with the reflected sound waves being picked up by the hydrophones to provide a 3D image of the geologyREAD MORE

What are seismic surveys?

Seismic surveys are used by a number of industries to produce detailed images of local geology. They use sound waves to build up a picture of underground rock formations, both onshore and offshore. By analysing the time it takes for the sound waves to reflect back to the surface, geophysicists are able to collect valuable information about rock types, gases, fluids and rock formationsREAD MORE
