據天然氣加工&液化天然氣2020年9月3日休斯敦報道，雪佛龍公司3日在休斯敦宣布，由于需要更多時間來修復其丙烷熱交換器的焊接，雪佛龍公司將把其位于西澳大利亞州的高更液化天然氣（LNG）廠的2號液化生產線的重新啟動推遲到10月份。

澳大利亞第二大LNG廠的2號液化生產線自5月份以來一直處于關閉狀態，進行例行維護。由于這個生產裝置的丙烷熱水壺出現裂縫，維護時間不得不延長。雪佛龍公司原本希望在9月初完成修復工作。

雪佛龍公司3日在一份聲明中表示：“在今年7月的例行維護中發現了熱交換器的焊接質量問題，雪佛龍公司預計熱交換器的維修工作將在9月份完成，并在10月重啟2號液化生產線的液化生產。”

雪佛龍公司表示，該公司將繼續履行合同義務，在長時間停工期間向西澳大利亞州國內市場提供天然氣和LNG。

澳大利亞制造業工人工會7月份曾表示，在2號液化生產線上8到11個熱水壺上發現了長達1米、深30毫米的裂縫，雪佛龍公司呼吁立即關閉整個LNG廠進行安全檢查。

西澳大利亞州工業監管機構8月份同意，允許雪佛龍公司關閉高更LNG廠的其余兩條液化生產線，以便分階段進行檢查和維修——1號液化生產線將于10月關閉，3號液化生產線將于明年1月關閉。

Chevron delays restart of Gorgon LNG unit

Chevron Corp anounced it will delay till October the restart of the Train 2 unit at its Gorgon LNGplant in Western Australia, as more time is needed to repair welds on its propane heat exchangers.

Train 2 at Australia’s second-largest LNG plant has been shut since May for maintenance, which was extended after cracks were found in the production unit’s propane kettles. The company had hoped to complete the repairs by early September.

“Chevron expects the repairs to the heat exchangers, where weld quality issues were discovered during scheduled maintenance in July 2020, to be complete and to restart production at Train 2 next month,” the company said in a statement on Thursday.

The company said it would continue to meet its contractual obligations to provide gas to the Western Australian domestic market and LNG through the prolonged shutdown.

Cracks up to one meter long and 30 millimeters deep were found on between eight and 11 kettles on Train 2, the Australian Manufacturing Workers Union said in July, calling for an immediate shutdown of the whole plant for safety inspections.

Western Australia’s industrial regulator agreed last month to allow Chevron to shut the remaining two Gorgon trains for inspection and repairs in stages — with Train 1 to be shut in October and Train 3 in January.
