A berthing licence is the correct term.
With apologies for going well into "matter of opinion" and "off topic" territories....
Before Premier and I seem to recall my first years with premier, I had a "berthing contract". While I'm aware it doesn't need to be, the term "licence" to me is associated with a government (local or central) agency granting permission to perform an otherwise-proscribed activity (Driving licence, firearms licence, dog licence, TV licence). Although there's bound to be someone who can, I can't really think of obvious examples where private companies call an agreement to provide services for money a "licence". Season ticket, pass, contract, agreement....not "licence".
YMMV but it seems absurdly grandiose.
