Basic Information
The term shadow fleet has been coined to describe the network of vessels used by Russia - and to a lesser extent Iran - to smuggle their oil and natural gas exports onto the world market in contravention of the various sanctions, embargoes and other controls to which they are subject at the time of writing (Jan, 2026). Whilst it is a neologism, there is plenty of scope for this term to be used in other, similar contexts in other times and places.
The shadow fleet is not a formal part of the merchant-marine of the nation to which it belongs, with the individual tankers being owned by shell companies which are in turn owned and operated at arms length. Registration is typically under a flag of convenience, under the flag of some nation known for its lax enforcement, and the ships themselves acquired, crewed and maintained as cheaply as possible. Some ships may even maintain several identities to hamper attempts at enforcement. Navigation transponders appear to be particularly prone to failure and it is not unknown for one to disappear from global tracking for days or weeks on end.
These vessels then sail from embargoed ports and either rendezvous at sea with ships carrying part cargo of legitimate product - which can the be adulterated with the illegitimate stuff - or sail directly to a port where their cargo can be accepted as-is.
Ironically, some of these measures actually make it easier to enforce against these tankers - turning off you navigation beacon in international waters makes you legally a navigation hazard and open to being boarded by any interested party (typically a national warship or coast guard vessel), being caught changing identities effectively makes you an unflagged vessel - and again, the rightful prey of any interested state, whilst within national waters (which can be hard to avoid in some places), lax standards of crewing and maintenance can lead to competence, safety or environmental infractions which can lead to seizure. Also many "flag of convenience" states are loathe to provoke major powers and can often be encouraged to agree to a boarding.

Game and Story Use
- Easily recycled in all sorts of environments.
- For example, there was a certain amount of shadow work around the end of the Atlantic slave trade, where false flagging and clandestine transfers of "cargo" became common as nations which still had exemptions and/or protection from anti-slaving patrols were used as cover and/or middlemen by those that did not. For example, once the Portuguese were limited to trading only in slaves taken in their own African colonies, a perhaps unsurprising number of unfortunates acquired elsewhere suddenly had their point of origin reinvented.
- In an "independent trader" sort of campaign PCs could easily end up involved in a similar sort of business to a Shadow Fleet - including acting as a third vessel to increase the anonymity of a clandestine handover.
- Worth mining for ideas about how any other kind of clandestine operative could maintain a cover in a modern surveillance-ridden society - or the kinds of measures their employers might need to take to get them paid.
- While switching between flags of convenience, it's entirely possible that a ship in a shadow fleet might decide to add a Jolly Roger to the mix, especially if they're running guns as well as fuel.
- One assumes that cutting out from transponder and GPS tracking involves some of the more archaic navigation methods such as dead reckoning or using the stars. A shadow fleet's crew may turn out to be quite useful if something like Kessler syndrome makes orbit inaccessible.
- Civilian PCs may find themselves in trouble if they stumble across a clandestine rendezvous - probably on the high seas, but possibly off the shores of some remote island…
- Presumably a shadow fleet can move people as well - which might also be useful in connection with certain PMCs with the same provenience.
