The innovative use of bespoke technology and the implementation of the world’s first real time program to measure sediment on mangroves from dredging, resulted in WorleyParsons and our customer Port Hedland Port Authority (PHPA) being awarded the prestigious Golden Gecko for Environmental Excellence in the awards 20th anniversary year.
The Golden Gecko awards are hosted annually by the Department of Mines and Petroleum and promote outstanding environmental achievement, one of the highest environmental accolades achievable by the resources development sector.
Our submission was based around the innovative approach developed by the Marine Environment team for conformance monitoring in South West Creek. PHPA were particularly concerned about the effect of dredging and disposal of dredge on the mangroves that are dominant in the region. In response to these concerns, WorleyParsons implemented the world’s first real-time program to measure dredging related sedimentation on mangroves using the sedimentation scanner, enabling the team to proactively manage impacts as they occurred.
The sedimentation scanners, deployed in thirteen locations in the mangroves throughout South West Creek, enabled sediment results to be measured against trigger levels on a daily basis via a remote scanning device that sent results directly to our office. The sedimentation can be calculated to the minute if required but daily calculation provided a proactive way to manage dredging related impacts. This innovation dramatically reduced HSE risk, exposure and environmental impact on sensitive ecosystems.
