Filling out routine reports and tracking spare-part lists will get easier because software can draft and update those records for you, so you'll spend less time on paperwork. What stays are the hands-on diagnostics and repairs of mechanical systems, plus the real-time decisions you make when something goes wrong at sea. Your day-to-day will still revolve around opening up engines, checking sensors, and guiding the team through fixes while keeping the vessel safe and legal under maritime rules.
Tasks at risk of automation

How to become a mechanic-captain
Becoming a ship's engineer officer is a regulated maritime career — there's no shortcut. You must train through an approved cadetship, gain sea time, and earn the relevant Certificate of Competency from the Maritime and Coastguard Agency (MCA) along with the required STCW certificates. Seniority is reached only by progressing up through the engineering ranks at sea.
1. Engineering officer cadetship
The standard entry is an approved marine engineering cadetship, sponsored by a shipping company and run through a nautical college. It combines college study with sea-going phases and leads to your first Certificate of Competency.
2. Higher maritime education
A foundation degree or degree in marine engineering through a maritime college deepens your technical grounding and supports progression toward senior engineer and command-level roles on board.
3. Certification and sea time
After training you must build sea service and progressively gain higher MCA Certificates of Competency and STCW certificates. Only with accumulated sea time and higher certification does a senior engineer post open up.
There's only one real path: an approved cadetship or maritime college, then sea time and the progressive MCA Certificates of Competency. All STCW certificates are mandatory. A senior position comes only after years of experience at sea.
