Autonomous navigation and unattended engine rooms are in use, but minimum manning rules block cuts. Reductions start once the IMO autonomous-ship code binds.

AI impact · ShrinkingSeafarer / Deckhand (Ship Ratings): what AI changes and what stays
Life on deck means hauling and securing heavy mooring lines while a ship rolls in rough water, chipping rust and repainting steel by hand between ports, and standing lookout watches alone through the night regardless of the weather.
What's already automated on modern ships?
Many ships already navigate with heavy computer assistance and can run engine rooms with no one physically stationed inside them around the clock, technology that's been adopted for years. What hasn't changed is the minimum number of crew a ship is required to carry, a rule that exists specifically so there are always enough hands on deck to handle an emergency.
Why do minimum-crew rules matter here?
International shipping rules currently require a set minimum number of people aboard regardless of how automated the navigation or engine room becomes, which means a shipping company can't legally cut deckhands just because the technology allows it. This site expects real reductions to wait until international rules for highly automated ships are actually put in place and enforced.
How does someone start a career at sea?
Entry-level deckhand roles typically don't require a degree; many people start through maritime academies or by working up from basic seaman certifications and time at sea. As automation changes bridge and engine-room work, building skill in the systems that monitor and support those automated tools is becoming as valuable as traditional deck skills like line handling and lookout watches.
