Cyclone Narelle disrupts Australia’s LNG and gas production amid global energy shortages
Consensus Summary
Cyclone Narelle has disrupted major liquefied natural gas (LNG) and gas production facilities in Western Australia’s Pilbara region, exacerbating global energy supply concerns. Chevron’s Gorgon and Wheatstone plants, along with Woodside’s Karratha Gas Plant and Santos’ Varanus Island facility, were knocked offline due to extreme winds (peaking at 180 km/h), with combined outages affecting roughly two-thirds of WA’s domestic gas supply. The cyclone forced evacuations of offshore workers, who have since operated facilities remotely, and officials confirm no disruption to domestic gas despite international LNG shortages. Concurrently, geopolitical tensions in the Middle East—including Iran’s closure of the Strait of Hormuz and missile strikes on Qatar’s Ras Laffan facility—have further strained global LNG flows, with the UAE’s Das Island plant also experiencing production disruptions. While WA’s energy minister insists operators are well prepared for cyclones, analysts warn of potential long-term impacts on regional industries and global markets, citing historical incidents like the 2008 Varanus Island explosion that caused prolonged supply shortages. The combined effects of natural disasters and geopolitical instability underscore growing vulnerabilities in the energy sector.

Key details reported by multiple sources:
- Cyclone Narelle caused outages at Chevron’s Gorgon and Wheatstone LNG plants in Western Australia’s Pilbara region, with Wheatstone going offline around midday Thursday and Gorgon experiencing a partial outage around 3pm Thursday
- Chevron evacuated offshore workers from Wheatstone (225km offshore) and Barrow Island (50km offshore) facilities by Tuesday and Thursday respectively, operating remotely after evacuations
- Santos’ LNG plant on Varanus Island (75km offshore) was knocked offline by Cyclone Narelle, with winds reaching 180 km/h early Thursday evening
- Woodside’s Karratha Gas Plant suffered a production interruption, contributing to the shutdown of nearly two-thirds of WA’s domestic gas supply over the past three months (per Australian Energy Market Operator)
- WA Energy Minister Amber-Jade Sanderson stated that LNG operators are well prepared for cyclones and there is no disruption to domestic gas supply, with no reports of damage to date
- The cyclone has passed Chevron’s major gas fields as it heads south, near Coral Bay midday Friday, 1000km north of Perth
- Qatar’s LNG exports were halted due to Iran’s closure of the Strait of Hormuz, with QatarEnergy’s Ras Laffan facility struck by Iranian missiles last week (accounting for ~17% of Qatar’s LNG output)
- The UAE’s Das Island LNG export facility (world’s second-largest exporter) had production partially resume on Tuesday after a missile attack, with no alternative route out of the Persian Gulf except the Strait of Hormuz
Points of Difference
Details reported by only one source:
- Chevron’s Wheatstone and Gorgon plants were knocked offline Thursday, with Barrow Island facility experiencing a partial outage a few hours after Wheatstone
- Santos’ LNG plant in Darwin was already offline for upgrades before Cyclone Narelle hit
- The Wheatstone offshore platform was operated remotely by staff in Perth since Tuesday after evacuations
- WA Energy Minister Amber-Jade Sanderson emphasized that LNG operators are ‘well accustomed to dealing with cyclones’ and ‘operate in a cyclone region’
- Four major gas facilities (Chevron’s Gorgon, Wheatstone, Woodside’s Karratha, and Santos’ Varanus Island) account for ~two-thirds of WA’s gas supply over the past three months
- Ex-Tropical Cyclone Narelle intensified to category four strength on Thursday, with gale-force winds peaking at 159 km/h on Barrow Island and 180 km/h on Varanus Island
- Woodside’s Karratha Gas Plant is linked to the North West Shelf project, with production expected to resume after mobilizing offshore workforces
- WA Energy Minister Amber-Jade Sanderson initially stated at a press conference she was unaware of damage, but later acknowledged evacuations of offshore workforces
- Independent gas analyst Jeanette Roberts referenced the 2008 Varanus Island explosion (Apache Energy) that shut down ~1/3 of WA’s domestic gas supply for two months, impacting industries like BHP and Burrup Fertilisers
- RATCH Australia (Kemerton power station) monitored the situation but did not anticipate material disruptions to gas-fired power in WA’s southwest
Contradictions
Conflicting information between sources:
- NEWSCOMAU states Santos’ Darwin LNG plant was offline for upgrades before the cyclone, but ABC does not mention this
- ABC reports Cyclone Narelle intensified to category four strength on Thursday, while NEWSCOMAU does not specify the cyclone’s intensity
- NEWSCOMAU claims no reports of damage to date, but ABC highlights physical damage (e.g., 180 km/h winds on Varanus Island) and production interruptions
- ABC states WA Energy Minister Amber-Jade Sanderson initially claimed she was unaware of damage at a press conference, but NEWSCOMAU only quotes her emphasizing preparedness without mentioning this contradiction
- NEWSCOMAU reports the UAE’s Das Island production partially resumed on Tuesday after a missile attack, but ABC does not specify the exact timing of the partial resumption
