Tied up with lots of lines. As someone said we used spacers, called 'camels' to stand the boat off from the pier or from other vessels tied between us and the pier. The ships divers monitor the barnacles situation. It has to be REALLY bad before they will haul a boat out of the water unscheduled to do anything about it. It is a HUGE evolution with a tremendous amount of setup to pull a nuke boat out of the the water. Normally it is handled when the boat is in a shipyard for pre-scheduled work.

I CO will only come into port without a tug if the weather is VERY calm and he is VERY confident of the shoreside line handlers. Again, as someone stated, you only have the screw and this little retractable electric motor that we call (no I am not kidding) "The Outboard" It can be used to manuever the stern around a bit but you are VERY limited in what you can do. It takes a VERY good skipper to get underway or pull in without any tugs.
That being said, I have done each ONCE and I think the OOD about had a stroke each time. Once was pulling into Lisbon Portugal and from what was said the weather was absolutely PERFECT. The wind and the current actually pushed us up to the pier gently. Even under these conditions the stress wa evident.
Leaving port was a totally different matter. In some BADDDDDD weather we LOST the after camel while outboard another submarine at about 11pm on a Friday. It was not a good situation and it created an abrupt unscheduled underway were we had not choice but to leave without a tug.
