CRYOGENIC PIPELINES TO REPLACE TRESTLE FOR LIQUEFIED GAS TRANSFER TERMINALS

Abstract

This project aims to develop geotechnical design tools, software, and publish design guidelines, for engineers to lay and keep cryogenic pipelines stable on the seabed. Transferring liquefied natural gas between floating tankers and onshore plants conventionally relies on a pipeline on a trestle system. As an alternative, novel subsea cryogenic pipelines are being considered. By ensuring the stability of subsea cryogenic pipelines laid directly on the seabed, this project will provide significant benefits to Australia’s liquefied natural gas trade by unlocking substantial cost savings, and making this key export industry more competitive.
