Any party within the chain can revoke the role of the next party within the chain.
NB! The rest of the chain then becomes superfluous because you have broken off the chain, you are then the only party within the chain who can reactivate the chain.
Go to the 
-button on the container for which you want to revoke the nomination and click on ‘Nominate inland operator’.
You can then click on the ‘Withdraw carrier’ button at the top right.
The chain has been broken and the nomination has been withdrawn. You can now freely nominate another carrier.
