Okay, I give up...
Two tugs, one bunker, Rotterdam.  New to the game, probably I'm an idiot.
But...
The bunker is moored to the pier...how do I cast off its lines?  I have tried from both tugs using the mooring feature.  I never get the option of "releasing" the bunker's lines from the pier making everything else quite useless.
thanks...
