My brother lives on a 100-year old, 130-foot long, 150-ton (metric, empty) barge. After years of moving from one place to another, he finally managed to obtain a permanent mooring (i.e. the mooring place is permanent, not his stay there).
However, that mooring came with nothing at all, so we had to:
1) fabricate mooring bitts, install them in 5'-deep holes filled with concrete
2) fabricate outriggers to keep the ship away from the embankment, where the water is too shallow. Each one weighs half a metric ton without the (carefully calculated) floats made with foam recovered from a scrapped dock
3) source (from a ship breaker 150 miles away) and adapt a 27-foot gangway.
And this is the end result:
