Cyclone Narelle disrupts Australia’s LNG and gas production amid global energy shortages
Consensus Summary
Cyclone Narelle caused widespread disruptions to Australia’s liquefied natural gas (LNG) and gas production facilities in Western Australia’s Pilbara region, exacerbating global energy supply concerns. Major plants operated by Chevron (Gorgon and Wheatstone), Woodside (Karratha), and Santos (Varanus Island) were knocked offline due to extreme winds, with evacuations of offshore workers and remote operations implemented. The outages affected nearly two-thirds of WA’s domestic gas supply, while the cyclone passed near Coral Bay on Friday. 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 exports. Both sources agree on the scale of the outages and the broader context of energy insecurity, though ABC provides more technical details on wind speeds and ministerial statements, while NEWSCOMAU emphasizes pre-existing upgrades and domestic supply assurances. Analysts warn of potential long-term impacts on regional industries and energy reserves, with WA’s government working to maintain domestic supply consistency amid the crisis.

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 the cyclone hit
- The Wheatstone offshore platform was operated remotely by staff in Perth since Tuesday after evacuations
- The UAE supplies 30% of China’s LNG imports and 53% of India’s LNG imports
- Four major gas facilities (Chevron’s Gorgon, Wheatstone, Woodside’s Karratha, and Santos’ Varanus Island) account for almost two-thirds of WA’s domestic 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 responsible for processing gas from the company’s 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 any damage, later acknowledging evacuations of offshore workforces
- A state government spokesperson confirmed Woodside, Santos, and Chevron had successfully demobilized offshore workforces amid Cyclone Narelle
- Jeanette Roberts (independent gas analyst) referenced the 2008 Varanus Island explosion (Apache Energy) that shut down ~33% of WA’s domestic gas supply for two months, impacting BHP, Rio, Burrup Fertilisers, and 150 small businesses
- RATCH Australia (operating Kemerton power station) said it was not anticipating material disruptions but monitoring the situation carefully
Contradictions
Conflicting information between sources:
- NEWSCOMAU states Santos’ Darwin LNG plant was already offline for upgrades before the cyclone, while ABC does not mention this pre-existing outage
- ABC reports Cyclone Narelle intensified to category four strength on Thursday, but NEWSCOMAU does not specify the cyclone’s peak intensity
- NEWSCOMAU claims no reports of damage to date, while ABC highlights specific wind gusts (159 km/h on Barrow Island, 180 km/h on Varanus Island) and production interruptions
- ABC states WA Energy Minister Amber-Jade Sanderson initially claimed at a press conference she was unaware of any damage, but NEWSCOMAU only reports her statement that operators are well prepared and there is no disruption to domestic gas supply
- NEWSCOMAU mentions the UAE supplies 30% of China’s LNG imports and 53% of India’s, while ABC does not provide these specific percentages
