There are three distinct concepts:

• A ship is launched. At this point the ship is named and the hull enters the water, however the ship is not yet complete, a great deal of work remains.
• A ship is commissioned. This usually applies to Naval vessels. Prior to this the hull is fitted out and sea trials are carried out. When the ship is commissioned it is designated ready for service and the crew formally join the ship.
• The ship sets off on its first voyage, the maiden voyage
