Qatar Running Short of LNG Tanker Storage as Hormuz Transits Stay Constrained

# What happened Qatar has been using available LNG tankers as short-term storage to keep its liquefaction trains running at reduced rates. That approach worked earlier in the summer after an increase in loadings in June, but the pool of empty vessels is now nearly exhausted.

A July diplomatic setback — the collapse of a US–Iran memorandum of understanding — has limited the ability to move empty LNG carriers through the Strait of Hormuz. As a result, many tankers that accepted cargoes remain at anchor inside the Gulf instead of leaving to free up storage capacity.

# The current snapshot

Available tanker storage is now very tight: approximately 10% of tanker storage capacity remains available. That scarcity increases the risk that Qatar will have to cut operations at its liquefaction plants again if storage and transit options do not improve.

# Why tanker storage matters Qatar is the world's largest liquefied natural gas exporter by volume. LNG facilities operate most efficiently when output is steady and plants can run close to nameplate capacity. When export routes are disrupted or outbound shipping is constrained, producers use tankers as floating storage to absorb temporary mismatches between production and export.

Floating storage is a stopgap. It requires empty or ballasted vessels to be able to leave and re-enter shipping lanes. If the number of available tankers falls and regional transit restrictions remain in place, floating storage cannot be rotated and will soon fill up.

# The role of the Strait of Hormuz Gulf exports. The collapse of a US–Iran MoU in July reduced the practical ability of Qatar-linked LNG vessels to transit the strait. With transit through Hormuz constrained, vessels that loaded in the Gulf have limited safe or commercially viable routes to leave and discharge cargoes, increasing the number of ships remaining idle in the region.

# Immediate risks for Qatar

• Storage shortage: With only about 10% tanker storage left, Qatar's operational flexibility is limited.
• Potential production cuts: If available storage continues to shrink, Qatar may have to step down plant output to avoid producing cargoes it cannot store or export.
• Concentrated intra-Gulf deliveries: A significant share of recent loadings has been intra-Gulf (for example, supplies to Kuwait), which helps absorb some volumes but does not remove the underlying export constraint.

# Near-term outlook

# What to watch next

• Kpler and other vessel-tracking updates for LNG carriers departing the Gulf.
• Any diplomatic developments between the US and Iran that might restore practical transit routes.
• QatarEnergy statements or operational notices about plant output adjustments.
• Regional moves to create or deploy alternative storage or routing arrangements.
