APPEA: Environment Award 2009
INPEX won the Australian Petroleum Production & Exploration Association (APPEA) Environment Award for the second time for developing an innovative solution to significantly reduce the environmental impact on sensitive mangrove communities during the 2009 onshore geotechnical investigation at Blaydin Point, Darwin.
The investigation was part of the front-end engineering and design (FEED) phase for the Ichthys LNG Project and the results are helping the engineering team design the most appropriate infrastructure for the onshore plant.
Some of the challenges included:
regular tidal inundation
working in soft substrates eg. sand and mud
presence of potential acid sulphate soils
sensitivity of the mangrove environment
potential threats from crocodiles, and
presence of biting insects.
For clearing, INPEX used a modified swamp excavator with a purpose-built disc-cutting attachment, which allowed mangroves to be cut near ground level, leaving rootstack intact to encourage rapid regeneration. For drilling, a number of options were considered and it was determined that the amphibious vehicle ("marsh buggy") on which a drilling rig could be mounted would be used.
Director of Project Coordination Eric Koning accepted the award on behalf of INPEX from the Federal Resources Minister Martin Ferguson.
APPEA: Environment Award 2007
INPEX was one of two companies judged worthy of the top environmental honour offered by the Australian Petroleum Production & Exploration Association (APPEA) for 2007.
At the award ceremony at the organisation’s annual conference in April 2008, Mark McCallum, APPEA’s Director, Industry Operations, congratulated INPEX on its "truly innovative and dedicated approach to ensuring as small an environmental footprint as possible" during its geotechnical and environmental drilling operations on the Maret Islands.
INPEX also engaged the services of local traditional owners to work with the drilling team throughout the entire program.
In summary, the selected solution achieved the following:
- No disturbance to any areas of heritage significance
- Minimal vegetation disturbance of only six-tenths of a hectare, or less than 0.1% of the total combined surface of the Islands. This compares very favourably with a traditional onshore drilling operation which would have impacted on more than 2% of the combined surface of the islands.
- Facilitated the future reuse of boreholes, removing the need for further borehole drilling on the islands.
In addition to the APPEA award, INPEX was short-listed for the Golden Gecko Award (administered by Western Australia’s Department of Minerals & Petroleum) for its geotechnical and environmental drilling operations on the Maret Islands.
The Golden Gecko Award is possibly the highest environmental accolade achievable in Western Australia’s resources industry. Being selected for the short list acknowledges INPEX’s commitment to best-practice environmental management.
