Gardline CGG completes BRAHSS field work

Gardline CGG Pte Ltd has completed field work activities for the last phase of the BRAHSS (Behavioural Response of Australian Humpback whales to Seismic Surveys) project.

Gardline CGG was contracted by the OGP (International Association of Oil & Gas Producers) on behalf of the Joint Industry Programme.

Gardline CGG deployed the multi-role seismic vessel MV Duke as a source vessel offshore Peregian Beach in Queensland (Australia) for the project.

BRAHSS is a five year study that aims to test how humpback whales respond to seismic air guns (2010 – 2014). During the study to date, small numbers of humpback whales migrating along both the east and west Australian coasts have been exposed to various size seismic sources.

The company says the 2014 field work season was successfully completed without any incidents or technical downtime. A total of 18 experiments (10 active and 8 controls) were carried out over the duration of the project. In addition, multibeam work was undertaken to help characterise the physical characteristics of the sea floor to aid in the propagation model of the area. The optional extension of 7 days was not exercised due to the highly effective work undertaken by the BRAHSS team and the crew onboard MV Duke, Gardline CGG says.

“The BRAHSS team would like to thank the crew of the MV Duke for the excellent work they did with us this season. They were very enthusiastic about the work, and their professionalism, high standards of operational competence and safety, and willingness to be flexible ensured that the project went smoothly in every way,” said Dr Michael Noad, BRAHSS Trial Director.
