Will AI replace Marine Engineers and Naval Architects?
Work in Marine Engineers and Naval Architects sits in the in-between: AI reaches some of it (~42% in theory) but is only measured doing about 4% today — part human, part machine.

How your 27 core tasks split
Top = what GPT-4 judged AI could speed up. Bottom = how much AI was actually used for these tasks (Anthropic's March 2026 report, usage from Aug & Nov 2025). The gap is the real story.
Back in 2023, GPT-4 judged AI could, in theory, assist with a moderate share of this job's tasks (~42%). By late 2025, real-world AI use had reached about 4% of its task activity (still rare). The gap between that 2023 forecast and today is the real story.
Where this job sits among 738 jobs
Each dot is one of 738 U.S. jobs. Right = AI can do more of it. Up = AI is actually used more.
The signals here line up
Theoretical reach (~42%), real-world use (~4%) and the task-level picture mostly agree — so this read is more reliable than for jobs where the signals contradict each other. Even so, AI-risk estimates shift by model (a 2026 study saw the "high-risk" share swing 2.7%–51.5%), so treat these as directional, not destiny.

- Prepare, or direct the preparation of, product or system layouts and detailed drawings and schematics.
- Investigate and observe tests on machinery and equipment for compliance with standards.
- Coordinate activities with regulatory bodies to ensure repairs and alterations are at minimum cost and consistent with safety.
- Maintain contact with, and formulate reports for, contractors and clients to ensure completion of work at minimum cost.
- Conduct analytical, environmental, operational, or performance studies to develop designs for products, such as marine engines, equipment, and structures.
- Determine conditions under which tests are to be conducted, as well as sequences and phases of test operations.
- Review work requests and compare them with previous work completed on ships to ensure that costs are economically sound.
- Analyze data to determine feasibility of product proposals.
- Supervise other engineers and crew members and train them for routine and emergency duties.
- Check, test, and maintain automatic controls and alarm systems.
- Evaluate operation of marine equipment during acceptance testing and shakedown cruises.
- Conduct environmental, operational, or performance tests on marine machinery and equipment.
- Design and oversee testing, installation, and repair of marine apparatus and equipment.
- Procure materials needed to repair marine equipment and machinery.
- Maintain and coordinate repair of marine machinery and equipment for installation on vessels.
How we measured this — and how fresh it is
AI's theoretical reach data: 2023
From GPTs-are-GPTs (Eloundou et al.), where GPT-4 rated how much of each task an AI tool could meaningfully speed up. This is the most recent open, commercially-usable occupation-level potential dataset — it dates to 2023. Newer multi-model re-runs exist but swing wildly (one 2026 study saw "high-risk" jobs range 2.7%–51.5% by model) and aren't openly licensed, so we show the stable 2023 baseline and pair it with newer real-world data.
