Entry & progression
Entry: the sea service is the credential; everything here is the application. Progression: most of it carries upward to every grade above DDE. One item on this list ends the conversation for most yacht crew. It is the first one.
Citizenship — read this before anything else
WARNING — US citizenship is mandatory. There is no engineer exception. 46 CFR 11.201(d): *"No officer endorsement may be issued to any person who is not a citizen of the United States."* The only carve-out anywhere in that section is for the OUPV on non-US-documented vessels — a deck ticket. A non-US citizen cannot obtain any USCG engineer officer endorsement, at any grade, by any route. Most yacht crew are not US citizens. This is the wall before all the other walls, and it is worth knowing on day one rather than after two years of sea time.
Firefighting — and yes, Advanced
11.201(h)(2)(iv): every national officer endorsement for engineers requires Basic AND Advanced Firefighting (STCW VI/1 and VI/3, Tables A-VI/1-2 and A-VI/3), completed within the past five years or supported by evidence of maintained competence. That includes DDE under 1,000 HP — the 18-year-old, smallest-boat, inland-only tier. Meanwhile a deck licence below 500 GT on oceans needs only basic firefighting (11.201(h)(3)).
Read that comparison honestly: the engineering entry bar is materially higher than the deck one. The Coast Guard has decided that the person who is alone with the machinery when it burns needs the advanced course. They are right.
Revalidation is not automatic. 11.302(d) and 11.303(d) say the Coast Guard "will only accept evidence of approved assessments conducted ashore" for the physical elements — donning an immersion suit, righting an inverted liferaft, jumping from a height, SCBA in smoke-filled spaces, live fire with fog, foam and dry chemical, firefighting with dangerous goods, and organising and training fire parties. Sea time revalidates the rest. It does not revalidate those. You go back ashore every five years.
First aid and CPR
11.201(i) requires them for every original officer endorsement. The exceptions written into 11.429, 11.456 and 11.467 are deck-only. Engineers get none.
The rest of the file
- TWIC, a medical certificate and a drug test (46 CFR 16.220) — Part 10 baseline for everyone.
- Physical validity: 12 months (11.201(f)(2)).
- Recency (11.201(c)(1)): "at least 3 months of required service… within the 3 years immediately preceding the date of application." Three years off the water and the file goes stale, however much service is behind it.
- Approval to test is valid 1 year (11.201(j)(2)). Do not collect an approval letter you have no time to use.
The examination
DDE requires one — 11.903(a)(34) — and the exam codes at 11.950 Table 1 confirm all three tiers are separately examined. There is one interesting door: 11.201(j)(1)(i) allows an orally assisted examination to be requested for any engineer endorsement limited to vessels of less than 200 GRT. The price is real: the endorsement is then limited to the route and vessel type on which the majority of the service was obtained. A narrower ticket, for an easier exam. Think hard before you take that trade.
Deck credit
11.504: deck service counts toward DDE (and toward CE-Limited and AE-Limited) for up to 25 percent or 6 months, whichever is less. The deckhand years are not wasted, but they are capped. Note that the cap is different at every rung — 3 months toward Third Assistant Engineer, 3 months toward OICEW. One number will not cover them all.
CAUTION — Pull the current NMC checklist The National Maritime Center publishes an application checklist for each endorsement, and the detail on it moves. The CFR is the controlling authority and is what this course cites; the checklist is what the evaluator works from. Get the current one for your tier before you post the file.
