At Chevron, we believe innovation is Australia’s most valuable resource. We are committed to developing leading edge technology and investing in research and development to enhance our environmental stewardship.
In our continual pursuit for environmental excellence, we work closely with the Perth Global Technology Centre and leading universities and research institutions to utilise technology to help protect the environment. Such examples include:
Unmanned Aerial Vehicles
We are using unmanned aerial vehicle (UAV) technology for our survey activities, as they reduce the need for people to access beaches and landscapes for undertaking environmental survey data.
Use of Unmanned Aerial Vehicles has helped us protect sensitive areas, yet still gain valuable and necessary high quality environmental survey data.
As part of our Wheatstone Project survey work, four UAVs were deployed to capture images of turtle tracks and nests on Ashburton Delta beach, Ashburton Island, Muiron Island and Peak Island. Results showed that the images captured provide sufficient information to determine turtle species and track details. Through this trial we have shown that UAVs can be used to gather the necessary information without exposing survey personnel, marine fauna and the environment itself to the health and safety risks involved with undertaking field surveys.
We are now examining where this technology might be applied to other types of environmental surveys.
Environmental Acoustic Recognition Sensors
We seek technical solutions to enhance existing quarantine management strategies and improve quarantine efficacy, particularly in surveillance and detection capability.
To help detect Asian House Geckos (AHG) activity on Gorgon Project cargo and vessels destined for Barrow Island, a unique acoustic device has been developed by Chevron in conjunction with researchers from Edith Cowan University’s School of Engineering.
Environmental Acoustic Recognition Sensor (EARS) can detect an AHG's call from up to 20 metres away.
The Environmental Acoustic Recognition Sensor (EARS) can detect a gecko’s call from up to 20 metres away. If the sound file confirms the presence of AHG, an alert is sent to the quarantine team that details time and location to aid in detection.
EARS has been implemented across fabrication yards in South East Asia and supply bases in Australia with immediate results. Coupled with quarantine’s existing surveillance and species control strategies EARS provides Barrow Island Quarantine with a 24 hour presence and has facilitated a more targeted approach to AHG detection.
Remote Operated Vehicles
Remote operated vehicles (ROVs) were used to complete a range of underwater surveys and studies for the Wheatstone Project. Capable of surveying a large area in a variety of sea conditions, ROVs reduce the need for using divers, presenting a number of safety advantages.
ROVs are capable of surveying a large area in a variety of sea conditions.
The ROVs provide quality digital still images and video footage to enable post-survey analysis. Their precise GPS system permits mapping of sensitive features within a survey area, increasing the accuracy of results.
