The world's largest ship sails to nowhere

[timelets]

In partnership with the Port of Rotterdam, the ship will be taken to Maasvlakte 2, an extension of the port, where a special pit has been drained to house the vessel.

After its completion, it will sail to the South Stream project in the Black Sea to lay pipelines there.

How is it possible when Russia is under sanctions and the South Stream is effectively frozen?
