Vayenga Maersk, currently at anchor off Rotterdam, and on continuous, scheduled shuttle between Rotterdam and St. Petersburg, has been refused entry to the Port of Rotterdam due to Russian cargo on board.
I am keen to see what Maersk's stance will be as more ports (hopefully) prohibit Russian ships to enter.
Meanwhile, what do (especially container) ships do with their embargoed cargoes?
In due course, I presume, a holding port for said cargoes will have to be found.

As the situation in Ukraine continues, A.P. Moller - Maersk is keeping a close eye on developments and assessing the best options for our customers and their cargo. Giving you the best ability to manage your supply chain is of the utmost importance to us and we are working to give you everything you need to run your global logistics in these circumstances.
To prevent congestion in key ports, we are moving cargo to and from Ukraine to ports with less yard density that still possess the required reefer plugs to retain perishable commodities, and earlier this week we announced a series of relief packages. We can already see some customers making use of these packages, and we strongly encourage all customers with cargo destined to or originating from Ukraine to discuss these possibilities with us in the interest of keeping operations as smooth as possible. Among the options are free Change of Destination (COD) services and no cancellation fees on bookings to and from Ukraine
