Australian refiner Viva Energy's refinery output for July-September fell on the year due to maintenance at the 120,000 b/d Geelong facility, while its Geelong refining margin (GRM) rose on the quarter and the year.
A 10-week turnaround at Geelong beginning in August impacted the refinery's volumes, with major maintenance to the residual catalytic cracking unit which is now complete and the unit restarted in mid-October, Viva said on 27 October.
Refinery output will fully return by mid-November when the ultra-low sulphur gasoline unit starts operations, ahead of previous guidance of December 2025. The total cost of upgrades is expected to be A$280mn ($183mn), net of the A$150mn granted by Canberra towards the works.
New federal fuel standards for gasoline will come into effect from mid-December.
GRM increased in the quarter after recovery from an unplanned outage at Geelong in the first half of the year, which resulted in minor turnaround activity and higher energy costs.
Group sales volumes rose slightly on the year boosted by commercial and industrial fuel and specialty sales, which grew 2.4pc on higher jet fuel sales, offset by retail fuel sales which were down by 2.4pc.
Commercial and industrial sales over October-December will be impacted by softer bunker demand, due to a weaker-than-usual cruise season in Australia, Viva said.
