There may be another spot / third-party LNG cargo developing at NFE's Altamira FLNG facility.

The latest official vessel schedule published by ASIPONA Altamira, updated on August 19, lists the LNG tanker AMUR RIVER for an operation on August 21 at 08:00.

What makes this interesting:

• AMUR RIVER is a 149,700 m³ LNG carrier.
• MarineTraffic shows the vessel arrived at the Altamira anchorage on August 19 at 10:46 and is currently at anchor offshore.
• Its reported draft is only 9.2 m, which appears consistent with the vessel arriving in ballast/light condition rather than carrying a full LNG cargo.
• The official ASIPONA schedule lists the operation as “ABARLOAMIENTO” — an alongside/mooring operation — with an estimated duration of 24 hours.
• The agent is Logística y Suministro Tritón, S.A. de C.V.

That last point is particularly interesting.

In ASIPONA’s official July 15 vessel-programming minutes, the same Tritón agency reported that:

PALU LNG would proceed to the NFE complex, berth alongside the NFE PENGUIN, and export 80,000 m³ of LNG.

Immediately afterward, ENERGY ENDURANCE was scheduled to do the same thing and export another 150,000 m³ of LNG.

So there is already a very recent precedent:

Tritón + LNG carrier + offshore alongside operation → NFE PENGUIN LNG export.

Now AMUR RIVER has arrived offshore Altamira and is being handled by the same agency for another “abarloamiento” operation.

There is another important clue.

According to Dynagas LNG Partners’ SEC filings, AMUR RIVER is under a long-term charter to SEFE Marketing & Trading Singapore, with the charter running into 2028.

That makes this look less like NFE simply repositioning LNG internally to Puerto Rico and more like a possible third-party sale to SEFE, or another short-term/spot cargo arranged through SEFE.

If AMUR RIVER loads close to its full capacity, the cargo could be roughly 145,000–150,000 m³ of LNG.

My interpretation

This is not confirmed yet as an NFE cargo.

The August 19 ASIPONA schedule does not explicitly state “NFE PENGUIN,” nor does it provide an LNG loading volume the way the July minutes did.

But the combination of:

1. a nearly empty LNG tanker arriving at Altamira,
2. an offshore “abarloamiento” operation,
3. the same shipping agent that handled the July NFE exports, and
4. AMUR RIVER being controlled commercially by SEFE

makes another NFE Altamira third-party LNG sale a fairly strong possibility.

The next confirmation points should be:

• whether AMUR RIVER actually moves alongside the NFE offshore complex,
• whether its draft rises materially after the operation,
• the next ASIPONA programming minutes,
• and its AIS destination after departure.

If its draft jumps from ~9.2 m toward loaded levels and it departs Altamira, that would be a strong indication that another full NFE cargo has been lifted.

This would also be notable because July already showed 230,000 m³ of explicitly documented NFE LNG exports through PALU LNG and ENERGY ENDURANCE.

If AMUR RIVER is another ~150,000 m³ cargo, Altamira's Q3 external sales activity may be materially stronger than it initially appeared.

This is vessel-tracking analysis and inference, not confirmation of a commercial transaction.

I went through the available Altamira port records, U.S. customs data and vessel movements, and July looks much stronger than it initially appeared.

There appear to be three separate Altamira LNG movements tied to Q3 2026.

1. ENERGOS PRINCESS — ~90,000 m³ to Puerto Rico

U.S. customs data shows:

• Vessel: ENERGOS PRINCESS
• Bill of Lading: ENHEFLNG53
• Origin / Place of Receipt: ALTAMIRA, MEXICO
• Arrival: July 22, 2026
• Destination: San Juan, Puerto Rico
• Cargo: 38,584.772 metric tons
• Volume: 566,928.87 LNG barrels
• Equivalent LNG volume: roughly 90,000 m³

This is an actual customs-recorded cargo, not an estimate.

NFE's own restructuring materials say Puerto Rico gas pricing is:

• Island-wide GSA: 115% Henry Hub + $7.95/MMBtu
• San Juan 5&6: 115% Henry Hub + $6.50/MMBtu

July Henry Hub averaged approximately $2.89/MMBtu.

That implies a Puerto Rico selling price of roughly:

$9.82-$11.27/MMBtu

90,000 m³ LNG is approximately 1.94 million MMBtu, implying roughly:

$19M-$22M of downstream revenue

depending on which Puerto Rico pricing bucket the gas ultimately falls under.

2. PALU LNG — 80,000 m³ from Altamira

This one is particularly interesting because we have an official Mexican port authority document.

ASIPONA Altamira's July 15 vessel-programming meeting states that PALU LNG was scheduled to arrive at the NFE complex and berth alongside NFE PENGUIN for:

“exportación de 80,000 m3 de gas natural licuado”

So:

• Vessel: PALU LNG
• Altamira operation: mid-July
• LNG loaded from NFE Penguin: 80,000 m³
• Approximate energy content: 1.72 million MMBtu

PALU subsequently called at Freeport before moving toward Europe, so I am counting only the 80,000 m³ specifically identified by Altamira authorities as NFE LNG, not the vessel's eventual full cargo.

July European TTF averaged approximately $18.07/MMBtu.

Using TTF simply as a market benchmark:

1.72M MMBtu × ~$18.07 = ~$31M

So the Altamira portion of the PALU cargo could represent roughly $30M-$31M of LNG value.

3. ENERGY ENDURANCE — 150,000 m³

The same official Altamira document states that ENERGY ENDURANCE would berth alongside NFE PENGUIN after PALU LNG finished operations and load:

150,000 m³ of LNG for export

AIS history confirms ENERGY ENDURANCE was at Altamira roughly July 17-20, and it subsequently crossed the Atlantic into the Mediterranean/Suez route toward Egypt.

• Vessel: ENERGY ENDURANCE
• Altamira: approximately July 17-20
• NFE LNG scheduled for export: 150,000 m³
• Approximate energy content: 3.23 million MMBtu
• Subsequent route: Egypt / Suez

This is the biggest of the three July movements.

July TTF averaged $18.07/MMBtu, while Egypt has recently been paying premiums over TTF-linked LNG prices.

Using roughly $18-$19/MMBtu as a reasonable benchmark gives:

3.23M MMBtu × $18-$19 = ~$58M-$61M

Again, the actual contract price is not publicly known.

Total July Altamira LNG identified

ENERGOS PRINCESS: ~90,000 m³

PALU LNG: 80,000 m³

ENERGY ENDURANCE: 150,000 m³

Total: approximately 320,000 m³ LNG

That is approximately:

6.9 million MMBtu / 6.9 TBtu

Using the observable Puerto Rico contract prices and July international LNG benchmarks, I estimate the revenue represented by these LNG volumes at roughly:

$105M-$115M

This is NOT a reported NFE revenue number. It is a rough valuation of the LNG movements based on publicly available quantities and market/contract pricing.

Why this matters for NFE Q3

NFE's March 2026 restructuring materials projected CoreCo Q3 2026 results of approximately:

• Gas revenue: $179M
• Power revenue: $33M
• Capacity revenue: $17M
• Other revenue: $68M
• Total revenue: $298M
• Adjusted EBITDA: $58M

The ~$105M-$115M represented by these three LNG movements alone would therefore be equivalent to roughly:

~60% of NFE's projected Q3 gas revenue

and

~35%-40% of projected total CoreCo Q3 revenue.

Obviously these cargoes were probably already contemplated to some degree in management's forecast, so they should NOT simply be added on top of the $298M forecast.

What matters is that we now have public evidence that a meaningful portion of the expected Q3 gas activity actually occurred.

There is also a potentially important margin story.

NFE's March materials targeted an Altamira FLNG production cost adder of around $2.46/MMBtu excluding 115% Henry Hub.

With July HH at ~$2.89, that implies a theoretical run-rate LNG production cost around:

115% × $2.89 + $2.46 ≈ $5.78/MMBtu

Even assuming actual Q3 costs are somewhat higher — around ~$6/MMBtu — LNG sold into an $18-$19/MMBtu international market potentially carries a very large commodity spread.

Very roughly, these three cargoes could generate $60M+ of cargo-level gross margin before shipping, vessel charter costs, terminal costs, SG&A and other expenses.

That is NOT the same thing as EBITDA, but for a company currently going through a liquidity-sensitive restructuring, this level of Altamira utilization is meaningful.

And the biggest takeaway for me is this:

Altamira isn't just producing LNG for Puerto Rico anymore.

In July we appear to have:

1. A Puerto Rico cargo
2. A partial international cargo via PALU LNG
3. A large 150,000 m³ international cargo apparently headed toward Egypt

If this export cadence continues through August and September, Q3 Altamira results could look substantially better than Q1, when NFE reported only $43.9M of LNG cargo-sale revenue.
