Rock, sediment and fishermen—insights on community engagement from the Ichthys LNG Project dredging program

Abstract

The Ichthys LNG Project is one of the most complex oil and gas developments ever attempted. One challenge of the construction phase was undertaking a major dredging program to create a safe shipping channel and berthing area for LNG carriers through Darwin Harbour to the onshore processing facilities at Bladin Point. Dredging was also undertaken to create a trench in Darwin Harbour for the gas export pipeline. The dredging program took about 16 months to remove more than 16 Mm3 of rock and sediment, with a six month break during the first dry season due to environmental uncertainties. Ongoing discussions with key stakeholders and the community prior to the start of dredging affirmed the social, cultural and economic values placed on Darwin Harbour by local residents. Plans were developed to provide key stakeholders and the wider community with transparent information on the project’s dredging, environmental monitoring and research findings. The key focus of the campaign was marine safety and an integrated and tailored approach was used to deliver this message. Valuable insights and lessons were gained from other major dredging programs undertaken in Australia and used in planning. The Ichthys LNG Project dredging program included a combination of initiatives that, when implemented together, led to environmentally and socially responsible outcomes.
