Offshore is not a problem, they build a factory on the coast and put it on a boat.
On shore is a problem - there is a lot of the world where people live that isn't close to a sea. Iowa has more than 6000 despite being hundreds of miles from the nearest sea. (most aren't even close to the Mississippi river)
