USCG-ENG-LTD-M1 · The Two Limited Grades
5 lessons
USCG-ENG-LTD-M1-A 1,600 GRT, oceans included, and the formula that sets your horsepower
Practice in examiner ↗USCG-ENG-LTD-L1.1The two Limited grades, and the name that does not exist46 CFR 11.501(a) lists thirteen national engineer grades. It is a closed list. Two of them are the Limited grades, and between them they cover the working life of most engineers who will never set foot on a tanker: Assistant Engineer-Limited, and Chief Engineer-Limited.USCG-ENG-LTD-L1.2Assistant Engineer-Limited — 46 CFR 11.522This is the entry point to the Limited ladder, and for a great many engineers it is the first officer endorsement they will ever hold. It is also the grade that turns a rating into an officer.USCG-ENG-LTD-L1.3Chief Engineer-Limited — 46 CFR 11.518This is the grade that runs the department. It is also the grade that opens the door to the unlimited ladder, which is why it matters far more than its modest tonnage ceiling suggests.USCG-ENG-LTD-L1.4The horsepower limitation — 46 CFR 11.503(b)Tonnage caps the Limited grades at 1,600 GRT. Horsepower is a second, entirely separate fence, and it is drawn around you personally, by a calculation performed on the ships you actually served on.USCG-ENG-LTD-L1.5The supporting requirements — citizenship, firefighting, modes and creditsThis lesson sets out the supporting requirements every engineer applicant must satisfy: US citizenship with no exceptions, mandatory Basic and Advanced Firefighting at all grades, recency and medical standards, the one-third propulsion-mode rule, how to add a mode later, and the deck-service credit limits for Limited grades.
USCG-ENG-LTD-M2 · Running a Watch, and Then a Department
3 lessons
USCG-ENG-LTD-M2-A Assistant to chief
Practice in examiner ↗USCG-ENG-LTD-L2.1The engineering watch — taking over, handing over, and what you are watchingA watch is a period of undivided responsibility for a running plant. Everything that happens in the machinery space while your name is against the watch is yours — including the things that started before you took over.USCG-ENG-LTD-L2.2Planned maintenance, and the maintenance that becomes a casualtyEvery machinery casualty at sea has a history. Almost none of them are surprises. They are deferrals that ran out of road.USCG-ENG-LTD-L2.3Leading the engine room teamThe step from good engineer to head of department is not a step up in technical skill. It is a change of job. You stop being the person who fixes things and become the person who is accountable for whether things get fixed.
USCG-ENG-LTD-M3 · The Plant at 1,600 Tons
3 lessons
USCG-ENG-LTD-M3-A Bigger machinery, more of it
Practice in examiner ↗USCG-ENG-LTD-L3.1Main propulsion — the diesel at scale, and condition monitoringA vessel just under 1,600 GRT is not a big ship, but it is a real one. The mains are medium-speed or high-speed diesels of serious output, they are worked hard, and a failure at sea is not an inconvenience. It is a casualty.USCG-ENG-LTD-L3.2The electrical plant — switchboards, blackout and recoveryHere is the irony. The electrical plant is excluded from the calculation that sets your ticket, and it is the system most likely to put you in the dark — and the one most likely to get you hurt.USCG-ENG-LTD-L3.3Auxiliaries — boilers, oily water separators, sewage, refrigeration and HVACThe auxiliaries are where a small engineering department loses most of its hours. They are also where the most serious legal exposure sits.
USCG-ENG-LTD-M4 · Chief on a Limited Ticket
3 lessons
USCG-ENG-LTD-M4-A Responsibility, compliance, and the crossover
Practice in examiner ↗USCG-ENG-LTD-L4.1The chief engineer's responsibility, and the relationship with the masterThe credential gives you authority over the machinery and accountability for it. It does not give you command. The master commands the vessel. You run the plant, you advise the master on what the plant can and cannot do, and you tell the master the truth.USCG-ENG-LTD-L4.2Surveys, inspection and the Certificate of InspectionInspection is not an event that happens to you. It is a continuous state that is occasionally checked. The chief engineer who starts preparing for a survey a fortnight before it has already lost.USCG-ENG-LTD-L4.3The crossover — how the Limited ladder becomes the unlimited oneThe Limited grades look like a side branch. They are not. They are a **doorway into the unlimited ladder**, and the door at the top of them opens much further up than almost anybody realises.
