On-Bottom Stability of Large Diameter Submarine Pipelines

海上石油和天然气开采每年为澳大利亚经济贡献约170亿美元。随着开采活动的增加，在澳大利亚水域安装的管道长度呈指数增长。在澳大利亚西北大陆架（NWS），一条大直径管道的典型成本约为450万美元/公里。底部稳定措施约占总成本的30%。预计该项目的成果将为目前正在开发的新项目（如Pluto， Browse， Sunrise和Greater Gorgon）节省大量成本，并将提供科学证据，支持现有干线的寿命延长审查。

Offshore oil and gas extraction contributes approximately $17 billion annually to Australian economy. As the extraction activities increase, the length of pipelines being installed in Australian waters increases exponentially. The typical cost of a large diameter pipeline on the North West Shelf (NWS) of Australia is approximately $4.5 million/km. On-bottom stabilisation measures account for approximately 30% of the total cost. It is expected that the outcomes of this project will enable significant cost savings for the new projects currently being developed such as Pluto, Browse, Sunrise and Greater Gorgon, and will provide the scientific evidence that will underpin the life extension reviews of existing trunklines.
