A sanctioned vessel that was previously reported to have transported weapons destined for Russian mercenaries has been traversing ports on the west coast of Africa since March, exhibiting what experts told Bellingcat  was an unusual set of movements and behaviours.

Patria (IMO: 9159921) has been sanctioned by the US, Ukraine and Canada.

Radio France International (RFI) reported last year that it was one of two ships to deliver weapons to Conakry in Guinea that were intended for the Kremlin-controlled Africa Corps and their operations in Mali.

Satellite imagery and Automated Identification System (AIS) data from Lloyd’s List Intelligence shows Patria has shuttled between the Port of Douala in Cameroon and the Port of Owendo in Libreville, Gabon four times since March. 

It is not clear what Patria has delivered or picked up at these ports. Nor is it clear why it has spent so long going back and forth between them. But experts Bellingcat spoke to said the unusual patterns of behaviour raised numerous questions.

Charlie Brown, a former US Naval Officer and Senior Advisor at United Against Nuclear Iran said the combination of Patria’s repeated regional port calls, extended periods at anchor, and an apparent absence of a normal point-to-point trading cycle warranted scrutiny, especially as the ship is under sanction and is previously reported to have shipped arms. 

Tracking the Patria

Patria is a cargo vessel that has a distinct shape and features. Its bridge is located on the bow and it has a bright red deck that contrasts with its blue hull and two yellow cranes. 

At the end of the deck, the ship has a built-in ramp for vehicles (the Patria is a so-called roll on/roll off, or RoRo, vessel that is designed to transport wheeled vehicles). Its chimney is located next to the ramp.

This, in combination with the length of the ship (101 m), allowed Bellingcat to pick the vessel out in satellite imagery. AIS data helped us further track its long journey which began in the Sea of Japan, in Russia’s far-east, in January.

For the most part, we were able to match Patria’s AIS position with corresponding satellite imagery. We found no evidence of obvious spoofing incidents (where a ship intentionally broadcasts misleading AIS data) by the vessel during its months-long voyage, however, there were some instances where satellite images were not available and thus spoofing by the vessel cannot be completely ruled out.

Examining the Patria’s Draught

We reviewed the draught of the ship at each port visit and found that the ship’s draught always dropped after a stay at the Port of Douala, suggesting it was unloading there.

A ship’s “draught” is the distance from the bottom of the hull (the keel) to the waterline. When loaded, a ship is heavier and sits lower in the water (e.g. a draught of six metres) than when it is unloaded (e.g. a draught of four metres).

In the period from March to July, the Patria made five port calls to Douala and each time the draught decreased. Conversely, it called four times at the Port of Owendo in Libreville, each time the draught increased, meaning the ship became heavier, suggesting it was loading.

The draught is self-reported by ships but usually when it arrives at ports this kind of data is checked – reporting accurate draught is also a safety issue for ships arriving and departing at ports. 

Bellingcat asked the ship’s owners, managers and both ports if items were being transferred from Libreville to Douala but did not receive a response at time of publication.

Brown, the former US Naval Officer and now a Senior Advisor at United Against Nuclear Iran, said Patria’s movements were unusual.

“A sanctioned vessel linked to a prior military logistics shipment spending nearly six months operating between a small cluster of West African ports, Douala, and Owendo, without returning to a clear commercial trading pattern warrants scrutiny,” Brown told us.  

“While innocent explanations such as mechanical issues, commercial disputes, lack of cargo, chartering delays, or prolonged maintenance are possible, the combination of repeated regional port calls, extended periods at anchor, and an apparent absence of a normal point-to-point trading cycle is atypical for a merchant vessel.” 

He added that the current period of more than 30 days at the Lagos Anchorage, in particular, is noteworthy. 

David Soud, Head of Research and Analysis at I.R Consilium also told Bellingcat that Patria’s prolonged Lagos Anchorage could have innocent explanations such as its need for ongoing repairs, or that its operators were out of money, but added that there could also be more calculated reasons and it was laying low for a while.

Bellingcat analysed AIS data from Lagos Anchorage and found that while there has been high congestion, no other RoRo or container vessel waited longer than 10 days to enter the port in the period that Patria has been at Lagos Anchorage. At time of writing, Patria has been in anchorage for more than 30 days.

Regarding the Patria’s apparent deliveries of cargo between Libreville in Gabon, and Douala in Cameroon, Soud told Bellingcat:

“Given the vessel’s history of transporting military equipment to African seaports for overland delivery to Russian and allied forces in the Sahel, it’s not out of the question that some form of supplies for Russian or other forces could be picked up in Gabon, whose government has developed a closer relationship with Moscow, to be discharged in Douala, which is the main entry point for goods going to Central African Republic.”

Bellingcat asked the Nigerian Ports Authority why Patria had been in anchorage for so long, whether it had applied to dock and whether the port was aware of its sanctioned status but did not receive a response at time of publication.

The ports of Douala in Cameroon and Owendo in Libreville, Gabon did not respond to Bellingcat’s requests for comment about the Patria’s visits and the cargo it was carrying.

Bellingcat also contacted the two companies connected to the vessel – Hanro Shipping and Sakhalin Shipping Company which are listed as the vessel’s owner and manager respectively in sanctions documents. We also contacted the company connected to JS Gratitude. We did not receive a response at time of publication.
