There may be different definitions, but according to the usual one, the French term “bâtiment” is an immovable asset. The English term “vessel”, depending on the definition provided by different departments on the Internet, is translated as “vaisseau” in French. Compared to “bâtiment”, a vessel is probably a moveable asset, but perhaps I am mistaken. Perhaps the definition is different.
