據(jù)世界天然氣網站7月28日消息 雪佛龍公司在發(fā)現(xiàn)丙烷換熱器內存在“焊接質量問題”后，正打算于9月將澳大利亞Gorgon液化天然氣工廠的第二條生產線重新上線。

作為計劃維護的一部分，這家美國能源公司5月23日關閉了位于西澳大利亞州巴羅島的大型液化天然氣設施的第二個生產裝置。

目標是在7月11日完成維護工作并重啟機組。

雪佛龍的一位發(fā)言人在周二的電子郵件評論中表示，公司已經完成了所有的工作，但生產線仍處于離線狀態(tài)。

發(fā)言人說：“一旦維修完成，我們預計9月初左右將安全開始2號液化天然氣生產線的重啟。”

與此同時，Gorgon 1號和3號生產線仍在繼續(xù)生產液化天然氣。

Chevron to restart 2nd Gorgon LNG train in September

Chevron is looking to place back online the second train at its Gorgon LNG plant in Australia in September after it found “weld quality issues” within the propane heat exchangers.

The US energy firm shut down the second production unit at its giant 15.6 mtpa LNG facility on Barrow Island in Western Australia on May 23 as part of planned maintenance.

It aimed to complete the maintenance works and restart the unit on July 11.

A Chevron spokesperson said in emailed comments on Tuesday that the company completed all the work but the train is still offline.

“A routine inspection of the Gorgon LNG Train 2 propane heat exchangers identified weld quality issues,” he said, adding that the unit has in total eighth exchangers.

“Repairs are underway and we have the necessary personnel with skills and knowledge to conduct the work onsite,” the spokesperson said.

Chevron is working with the regulator, the Department of Mines, Industry Regulation and Safety, in planning and implementing this work.

“Once repairs are complete, we expect to safely commence LNG Train 2 restart activities around early September,” the spokesperson said.

In the meantime, Gorgon trains one and three are continuing to produce LNG.

The spokesperson added that Chevron continues to deliver LNG and domestic gas under its contractual commitments with customers.
