From our early investigations, many cargo ships already maintain sufficient moveable ballast (ie: water tanks) in order to handle dock operations, that they can also handle the roll moment from the sails. Maintenance is on our mind too. The possibility with a containerized solution is as easy as "ship it back to the manufacturer by putting a shipping label on it" for maintenance, and we can make sure to have spares dockside for our customers while their main device is being serviced.
