BJ Process and Pipeline Services (BJ PPS) has successfully completed a commissioning contract for Technip Oceania Pty Ltd. BJ PPS supplies nitrogen-helium leak detection services on process piping and vessels associated with the Otway Gas Processing Plant and the remotely-operated platform located offshore Victoria in southern Australia.
Technip Oceania is developing the Otway project on the Thylacine and Geographe gas fields to supply up to 10% of southeastern Australia's demand for natural gas.
The primary elements of the Otway project are the onshore central processing plant at Port Campbell, 200km southwest of Melbourne, and a remotely-operated offshore platform. The gas plant and platform are connected by a network of onshore and offshore flowlines that will have approximately 220 million scfd capacity when operational.
Using nitrogen converters that deliver high flow and high pressures for fast, effective leak testing, BJ PPS performed nitrogen-helium leak testing on all of the process facility's pipework and vessels to ensure Technip Oceania a safe, leak-free start-up when they began producing live gas.
Technical expertise and equipment to carry out the Technip Oceania operation was provided by BJ PPS from its base in Perth, Western Australia.
"We are extremely pleased to have had the opportunity to contribute to the safe operation of the Otway Gas Processing Plant," said Lindsay Link, general manager of BJ PPS. "Critical leak detection services were successfully completed, which means that Technip Oceania can rest assured that no hydrocarbon emissions will be released into the atmosphere upon start-up," he added.
As a result of its expertise and positive performance, BJ PPS has also been retained to provide pipeline maintenance and support services on a call-out basis, as required.
Over the life of the Otway Gas Project, the Thylacine and Geographe fields are expected to produce 950 billion cubic feet of raw gas (or 885 petajoules of natural gas), 12.2 million barrels of condensate and 1.7 million tones of liquid petroleum gas.
