Decent LNG tanks seems to have a boil off of about 0.05% of max volume per day. So after some 3 years (1000 days), your tank would be half empty. But I'd wager the rates are a lot higher in ships, since they have some weight and space restrictions you don't get on land.

Use some to power the engines, put the rest through a recondenser? There's probably a financial optimum there somewhere.

Yes but they can get quite close to that. And voyages don't last that long.

That's a fair point. Imagine the cost just having a whole ass ship shitting there, doing literally nothing.

That would be wasting money, ships are expensive to charter.

Whoever operates them have every interest to have them moving about.
