Qatar exported close to a fifth of global LNG supply through the Strait of Hormuz in the 2025 baseline. It has no LNG pipeline and no terminal that avoids the strait. Two of fourteen liquefaction trains were damaged on 18 March 2026, with repairs estimated at up to five years.
Overview
Every other exposure in this module has a partial remedy — a pipeline, a longer voyage, a different coast. Qatari LNG has none. Gas reaches distant markets as a liquid in a ship, and the alternative to a ship is a pipeline that was never built, so the whole of Qatar's export capability is one complex at Ras Laffan and one waterway. The Energy Information Administration recorded Qatar as exporting close to a fifth of global LNG supplies through the strait in 2025. On 2 March 2026 the complex was struck and QatarEnergy suspended LNG production; on 18 March a further attack damaged two of fourteen liquefaction trains, around 17% of export capacity, with QatarEnergy estimating repairs at up to five years. The binding constraint on Qatari exports through the war has nonetheless been transit rather than liquefaction: cargoes that can be made cannot always be moved.
Why it matters
Qatar is the state in this system with the most to lose from a closed strait, the host of United States Central Command's forward headquarters, and the party Tehran will still talk to. Its exposure is not a consequence of its politics — it is a consequence of physics, and it cannot be negotiated away or built around on any timescale that matters.
What depends on it
Total. There is no Qatari LNG route to market that avoids the Strait of Hormuz, and no capacity elsewhere replaces the volumes on the same timescale. Downstream, the dependence runs to Asian markets above all — around a quarter of Qatari LNG exports were destined for China in 2025 — with European buyers exposed through price rather than through direct supply.
What disruption does
Liquefaction capacity removed here is not replaced elsewhere on the same timescale, so the adjustment appears as widened price spreads between the American, European and Asian gas markets rather than as a physical shortage in any one of them. The transmission path is authored as an impact chain.
Nodes
Each node is a map marker this module already publishes, with its role in the system, in the order this record authors them. Not a route: no geometry, no distances, and no direction of travel is implied.
The world's largest natural gas field, lying offshore across the maritime boundary between Qatar and Iran. Qatar calls its side the North Field or North Dome; Iran calls its side South Pars. A broad, deliberately imprecise marker for a single geological structure.
In this systemThe offshore field, shared geologically with Iran. A shared reservoir and NOT a shared enterprise — see the record's own note below.
Why it mattersIt is a shared reservoir and NOT a shared enterprise. The two states have developed their sides separately — Qatar with international partners, Iran alone and, on reported evidence, in production decline. Vigil records the geology and authors no bilateral arrangement, because none was found: a shared field is not cooperation, and treating it as such would invent a relationship the evidence does not support.
What to watchWhether either side's development posture changes, and whether any joint arrangement is ever announced.

Qatar's liquefied natural gas export complex, and the point through which close to a fifth of global LNG supply left the country in the 2025 baseline. Two of fourteen liquefaction trains were damaged on 18 March 2026.
In this systemLiquefaction and loading. Two of fourteen trains damaged 18 March 2026; repairs estimated at up to five years.
Why it mattersThere is no alternative to it. Qatar has no LNG pipeline or terminal that avoids the Strait of Hormuz, so this complex and that waterway together constitute the whole of the country's export capability. QatarEnergy estimated repairs to the damaged trains at up to five years.
What to watchWhether the damaged trains return to service, and on what timescale.
PortConfidence: HighAs of 2026-09Show on the map →
The waterway connecting the Gulf to the Gulf of Oman and the open ocean, comprising Iranian and Omani territorial waters. Around 20 million barrels a day of crude oil and petroleum products moved through it in the 2025 baseline, with close to a fifth of world LNG exports.
In this systemThe only route to market.
Why it mattersEvery Gulf Arab producer except Oman must pass this water to reach a customer, and so must Iran. It is the single point on which the region's export economy, and a material share of the world's, converges. The alternatives to it carry between a sixth and a quarter of what it normally moves, and for LNG they carry nothing.
What to watchWhether commercial transit resumes at scale, and on what insurance terms — the strait's usable state has been set by commercial risk rather than by physical blockade.

Alternatives and redundancy
None. No LNG pipeline, no alternative liquefaction site outside the strait and no overland route exists, and none can be built on a timescale relevant to this conflict. This is the only system in the module for which the honest answer to "what is the alternative" is nothing at all, and the module states it plainly rather than describing a theoretical option.
Ras Laffan struck; QatarEnergy suspended LNG production. Mesaieed's power-plant water tank was struck the same day, halting downstream petrochemical output. Iran's defence ministry reported the attacks while Iranian officials publicly denied targeting Gulf energy facilities.
A further attack damaged two of fourteen liquefaction trains, representing around 17% of Qatari export capacity. QatarEnergy estimated repairs at up to five years as of 19 March. A separate event from 2 March, and recorded separately.
Transit rather than liquefaction became the binding constraint on exports, with cargoes unable to move reliably through the strait.
Economic implications
A multi-year capacity loss in a market with few short-notice substitutes changes the structure of global gas trade rather than producing a temporary disturbance in it.

Transmission chains through this system
What remains unknown
- Export volumes during the war are reported rather than published by the operator, and the 2026 forecast of roughly half pre-conflict volumes is a trade-press figure.
- The five-year repair estimate is QatarEnergy's own and has not been independently assessed.
Readings the evidence also supports
- Reduced Qatari exports are consistent with the liquefaction damage and equally with the transit constraint, and the two operated at once. The record separates them rather than attributing the shortfall to either.
Listed because the record's own assessment is not the only one its sources permit — not as a hedge on the assessment above.
