Shadow, look-ahead'' models keys to pipeline-transient control

TLDR: A real-time dynamic two-phase model of the pipeline system and relevant portions of shore facilities is being installed for Woodside Offshore Petroleum Pty. Ltd.'s North West Shelf gas project.

Abstract: A real-time dynamic two-phase model of the pipeline system and relevant portions of shore facilities is being installed for Woodside Offshore Petroleum Pty. Ltd.'s North West Shelf gas project. The trunkline management system (TMS) which utilizes dynamic pipeline and plant process simulation is scheduled to start up near the end of the first quarter of 1994 at Woodside Offshore's plant at Karratha, Western Australia. The TMS is a real-time dynamic two-phase model of the pipeline system and relevant portions of the onshore facilities. Its budget was approximately $4 million (Australian). This concluding of two articles describes the models incorporated in the system. Part 1 described the operating conditions that prompted the systems's installation.
