Australian gas pipeline operator Jemena is to repair damage to its 145 TJ/d (3.9mn m³/d) Queensland Gas Pipeline (QCP) connecting Wallumbilla in Queensland state to industrial users near Gladstone after a fire-related disruption.
Queensland Fire and Emergency Services responded on 5 March to an incident between the Rolleston compressor station and Oombabeer, 190km west of Gladstone, Jemena said, with the company's crews now working to prepare the affected section of the QGP for repairs.
Jemena organised on 6 March to supply additional gas from Australian independent Santos' 7.8mn t/yr Gladstone LNG (GLNG) gas pipeline to reach affected customers, which has restored some gas flows to the 627km pipeline.
The Australian Energy Market Operator is issuing directions to large industrial users to curb gas use, Jemena said, although no residential customers were affected.
Australian chemicals and explosives firm Orica confirmed its Yarwun plant was affected by the disruption. It was working with Jemena to reduce cyanide production at the site until the incident is resolved, a Orica spokesman said. Yarwun's ammonium nitrate production is continuing as normal and Orica does not expect any supply disruption to customers currently, the spokesman said on 7 March. Yarwun has capacity to produce 530,000 t/yr of ammonium nitrate and 95,000 t/yr sodium cyanide for the resource sector, exporting more than 50pc of this output. Yarwun can also produce around 420,000 t/yr of nitric acid.
Rio Tinto has three aluminium facilities in the Gladstone area — the Boyne smelter and the Yarwun and Queensland alumina refineries — possibly also affected by the disruption.
Flows to the Queensland liquefaction plants including GLNG, the 9mn t/yr Australia Pacific LNG and 8.5mn t/yr Queensland Curtis LNG projects were 4,049TJ on 29 February, marginally higher than 4,013TJ a week earlier.
Further gas could be released to the domestic market, as GLNG has a short maintenance planned for 11-13 March following a similar downtime during 26-28 February that took the equivalent of half a train of the two-train project off line.
