What the GasLog Strikes Mean for LNG Operators and Their Underwriters

For five months the Hormuz crisis has been a tanker story. Crude carriers hit, product tankers rerouted, VLCCs priced out of transits they had made routinely for decades. LNG featured in the coverage mostly as a supply statistic, a fifth of global flows sitting behind a closed strait.

That changed over the last week of July. Two vessels from the same fleet were struck in two different seas in four days, one of them left without propulsion in the middle of the Strait of Hormuz with a full cargo aboard. LNG is no longer a bystander in this conflict, and the coverage implications are meaningfully different from those facing the crude fleet.

What Happened

On July 29 the GasLog Salem caught fire at Egypt's Damietta port after a drone struck the adjacent US-owned FSRU Energos Winter. Both fires were extinguished and neither vessel sank. That incident was itself notable as the first drone strike on Egyptian port infrastructure in this conflict, and it moved the campaign well outside the Gulf.

Three days later came the more serious event. The GasLog Shanghai, a Bermuda-flagged 155,000 cbm LNG carrier built in 2013 and on bareboat charter to GasLog, was struck at 23:30 UTC on July 31 approximately 11 nautical miles northeast of Lima, Oman, while outbound through the strait. The projectile hit the portside engine room and caused a fire, which the crew extinguished. The fire and resulting explosion produced a blackout, and the vessel lost propulsion entirely. UKMTO confirmed no casualties and no environmental damage, and did not attribute responsibility.

The vessel had loaded Qatari cargo around July 27, called at ports in Qatar and Kuwait, and was transiting the southern corridor when it was hit. Its AIS was switched off at the time of the strike, which is contrary to standard practice and tells you something about how operators are now approaching that passage.

A separate UKMTO alert the same night reported a Liberian-flagged tanker 21 nautical miles northeast of Khasab observing a large splash and explosion in close proximity. No damage, no injuries, voyage continued.

The pattern matters more than any single incident. The GasLog Shanghai is the second Qatari LNG carrier struck on the US-coordinated southern route since the ceasefire framework collapsed in early July. On July 7 the Qatari LNG tanker Al Rekayyat was hit near the strait, prompting Qatar, the world's second largest LNG exporter, to suspend shipments through the corridor for roughly three weeks. Traffic had only recently resumed under special arrangements when the Shanghai was struck.

Iran does not recognize the southern corridor in Omani waters where the US provides guided transits, and has repeatedly threatened vessels using it. The day before the strike, Iran's Persian Gulf Strait Authority stated that normal transit remains unfeasible while U.S. military operations continue, and that navigation permits would only be reconsidered once conditions stabilize.

Why LNG Is a Different Risk

The insurance consequences of an LNG casualty diverge from a crude casualty in four respects, and each one compounds the others.

Hull values run roughly double. A conventional 174,000 cbm newbuild currently prices between $200 million and $220 million, with Korean yards commanding $215 million to $220 million and Chinese yards $200 million to $210 million. Five year old carriers hold at approximately $165 million to $180 million, ten year old ships at $140 million to $155 million. A VLCC by comparison sits at $100 million to $150 million. Since war risk additional premium is charged as a percentage of insured value, the same rate produces roughly twice the premium on an LNG carrier.

The cargo can be worth as much as the ship. This is the point most often missed outside the LNG trade. As David Smith, head of the marine arm at broker McGill, put it, a new LNG vessel might be worth $200 million to $250 million and the cargo could be worth the same again. On a crude voyage the cargo is typically a fraction of hull value. On an LNG voyage, insuring the cargo can approach doubling the total insurance cost for the transit. Charterers and traders carrying that cargo exposure are facing premium arithmetic that has no equivalent on the tanker side.

There is no alternative route. Saudi Arabia's East-West Pipeline to Yanbu and the UAE's Abu Dhabi Crude Oil Pipeline carry a fraction of Gulf export volumes, and neither addresses Qatari LNG, which has no overland export option whatsoever. A crude cargo can go around the Cape at a cost. A Qatari LNG cargo either transits Hormuz or it does not move.

Loss of propulsion is a more serious condition. A disabled tanker adrift is a salvage and pollution problem. A disabled LNG carrier is that plus a cargo that continues to boil off and requires power to manage. Modern carriers hold boil-off to 0.08 to 0.10 percent per day against 0.15 percent on older ships, but a blackout removes the reliquefaction and gas handling capability that keeps the system in equilibrium. The GasLog Shanghai lost propulsion with a full cargo in a strait where salvage assistance carries its own war risk exposure. Nothing about that situation resolves quickly.

What This Costs

The pricing structure is worth restating because it determines who absorbs the increase.

Hull war risk operates on an annual baseline policy, typically priced in the hundreds of thousands of dollars, covering perils including war, revolution, terrorism, strikes, riots, and civil commotion. Underwriters then retain the right, though not the obligation, to charge an additional premium for each transit through a designated high risk area. Those APs can be set as underwriters see fit, and are sometimes waived entirely for favored clients, particularly those placing hull business with the same firm.

Before hostilities, Persian Gulf transit APs ran around 0.2 to 0.25 percent of insured value. For a $150 million LNG carrier that is roughly $300,000 to $375,000 per transit. Material, but absorbable.

Current pricing has no consensus, and the spread itself is the story. Robert Peters of Ambrey noted the market has not settled on an agreed range, with figures running from one to five percent. Smith at McGill put it at anywhere between three and a half and ten percent, moving almost hourly. Lloyd's List reporting found safer propositions getting away with one percent or less while high risk vessels were quoted 7.5 percent and heading toward ten percent or more within a day, with U.S. nexus tankers attracting the nickname missile magnets and the steepest quotes.

Run that against LNG values. At one percent, a $200 million carrier pays $2 million per transit. At five percent, $10 million. At ten percent, $20 million. Add cargo cover at comparable value and the figure can double again. For historical context, the typical rate during the 1980s tanker war, when Iraq attacked 283 vessels and Iran 168 over eight years, was around five percent.

The cancellation structure is equally consequential. War risk underwriters can cancel with seven days notice under Lloyd's wordings and 48 hours under some U.S. wordings. Major clubs including Gard, Skuld, and NorthStandard issued formal cancellation notices for the Persian Gulf on March 1, and cargo insurers issued 48 hour and seven day notices of their own. Cover that exists today is not cover you can count on for a voyage fixed next month.

The Practical Position for LNG Operators

Several things follow from the last week that are worth acting on rather than monitoring.

Check your agreed value. Hull policies are written on an agreed value basis, and LNG values have moved. If your fleet was last valued when secondhand tonnage sat at different levels, a total loss settlement may not reflect replacement cost. This is the least glamorous item on the list and the one most likely to matter if the worst happens.

Understand who pays the AP. Additional premium for a listed area transit is a cost that charter parties allocate, and standard wordings vary considerably in how they do it. At $2 million to $20 million per transit, an ambiguous clause is not a drafting nicety. Whether owners or charterers bear the AP, and whether there is a cap, needs to be explicit before the fixture.

Confirm your cargo position separately. Owners who assume the charterer's cargo cover responds are relying on an arrangement they have not verified. With cargo values approaching hull values, this is not a gap to discover after a casualty.

Review the AIS question deliberately. The GasLog Shanghai had its AIS off, which is contrary to standard maritime regulations. Operators are making that choice as a security measure, and it is understandable. It also creates exposure. Switching off AIS can affect flag state compliance, may bear on the P&I position depending on club rules, and complicates the evidential picture after an incident. Whatever your policy, make it a documented policy with a recorded rationale rather than a master's discretion.

Engage your club on loss of propulsion scenarios. A disabled LNG carrier with cargo aboard raises questions about salvage engagement, crew evacuation, cargo management, and pollution liability that differ from the tanker equivalent. Have that conversation before you need the answers.

The Structural Problem

There is a systemic dimension here that operators should factor into longer term planning.

The reason the market cannot price this well is that Hormuz has no bypass. Red Sea disruption pushed vessels around the Cape at a cost that could be calculated. Hormuz offers no equivalent, and for Qatari LNG specifically there is no overland option at all. That converts a regional security problem into a supply problem with no engineering solution, and it means the risk premium is unlikely to disappear when the shooting stops. Analysts expect an energy infrastructure risk premium to persist long after fighting ends.

Underwriters are pricing an exposure they cannot diversify away from, on assets worth twice a tanker, carrying cargo worth as much again, on a route with no alternative. The spread between one percent and ten percent is not market inefficiency. It is an honest reflection of a risk nobody has a good model for.

Two GasLog vessels in four days is the market's clearest signal yet that LNG is inside the target envelope rather than adjacent to it. Operators who have been treating the Gulf war risk conversation as a tanker conversation should stop.
