Maritime pressure doesn’t necessarily stop trade flows, it makes them longer, slower and more expensive. ⏱️⛽💰

One queue alone stretched for more than 30 nautical miles (≈50 km), while waiting times around Ust-Luga/Laukaansuu reached nearly 5 days. 🛑 Pressure on Russia's Black Sea logistics is reportedly shifting part of the cargo flow north, adding pressure on Baltic terminals.

🚨🚨🚨 A maritime bottleneck is building off 🇷🇺 Russia's Baltic ports. As of 30 September, around 150 vessels were reported waiting in the Gulf of Finland for Russian ports: 65 tankers and 85 cargo vessels.

That's an interesting contrast with recent European boardings of Russia-linked shadow fleet tankers, where authorities have publicly documented the grounds for intervention, including suspected false-flag operations and verification of a vessel's nationality under Article 110 of UNCLOS. 👀

A few hours later, VÄSTERBOTTEN was allowed to continue its voyage. So far, 🇪🇪 Estonian authorities say they have received no official explanation for the detention or the outcome of the inspection.

🚨🚨🚨 Russia's detention of 🇨🇾 VÄSTERBOTTEN (IMO 9436226) didn't last long. The cargo ship was stopped and inspected by 🇷🇺 Russian border guards while transiting Russian waters on its way to Sillamäe, along a route used under an arrangement between Russia, Estonia and Finland.

The move highlights a broader maritime trend: the gradual emergence of a Russian LNG shadow fleet, following the model already seen on a much larger scale with oil tankers. By targeting the carriers themselves, London is going after a key logistical bottleneck in Russia's LNG export chain. ⚠️

🚨🇬🇧 The UK has sanctioned five more LNG carriers linked to Russia's energy trade. The five LNG carriers designated today are 🇷🇺 CHAIVO (IMO 9331048), PORTOVYY (IMO 9246621), ALEKSEY KOSYGIN (IMO 9904546), KONSTANTIN POSIET (IMO 9904704) and PYOTR STOLYPIN (IMO 9904675).

5/5 By 23 September, SARMAT had left the area and was observed north of Skagen heading NW. The alert was lifted. But a Russian tug spending days manoeuvring with seabed-capable equipment around critical Danish subsea infrastructure is not something to dismiss as routine.

4/5 There was another interesting detail. SARMAT reportedly continued the same sailing pattern throughout the weekend. When a local ferry asked it to move away from its planned route, the response was: "not possible, in operation." Asked what operation: "towing."

3/5 The activity was unusual enough for Læsø municipality to activate its crisis preparedness. Emergency power readiness was checked, while local authorities explicitly logged a potential risk of sabotage of subsea cables. That does not mean sabotage was occurring.

2/5 SARMAT was towing a jack-up barge fitted with three legs and an excavator, equipment designed for offshore work and capable of operating directly on or around the seabed. That makes the location and repeated movements particularly noteworthy.

🚨🇷🇺🚢🇩🇰👀 1/5 A Russian tug spent five days operating near critical Danish subsea cables. Between 18-23 September, 🇷🇺 SARMAT (IMO: 8027133) repeatedly operated between Læsø and mainland Denmark, close to the routes of the island's power and data cables.

In mid-September, YURIY ARSHENEVSKIY sailed with 🇷🇺 ANASTASIIA (IMO 9349291), escorted by the Russian Navy landing ship 🇷🇺 ALEKSANDR SHABALIN, to 🇱🇾 Tobruk, where Russian military and logistics vehicles were unloaded.

Its next move will be worth watching. A northbound transit through the Bosphorus into the Black Sea remains a possibility, although its destination is still unclear.

🚨🇷🇺 YURIY ARSHENEVSKIY (IMO 8406705) could possibly be heading for the Black Sea. Since 25 September, the Russian cargo ship appears to have remained off 🇹🇷 Tuzla, after transiting the Dardanelles.

Its track off Ireland also shows repeated AIS gaps, interrupted by brief transmissions, a pattern observed on other sanctioned tankers transiting the area. Another Russia–India oil shuttle appears to be resetting for its next cycle. 🔁

🚨 Sanctioned tanker 🇸🇱 MIRES (9299771) is currently heading north off Ireland Sanctioned for transporting 🇷🇺 oil, MIRES left Russia in early Aug at 15m draught, reached 🇮🇳 Mumbai and departed at 9m. It is now returning north at the same draught, consistent with a ballast voyage back toward the Baltic.

Flag states are pushing sanctioned tonnage out. Meanwhile, 107 ships joined the 🇷🇺 Russian registry between Jan 2025 and June 2026, 87% already sanctioned. The shadow fleet isn’t disappearing, it's running out of flags. 👀
