AUS-EC3-L1.1

What the certificate actually lets you do

This lesson sets out exactly what the Engineer Class 3 Near Coastal certificate authorises: chief-engineer command up to 3000 kW across the full Australian EEZ, unlimited outboard entitlements, why engineering scope is measured in kilowatts rather than tonnes, and an unresolved AMSA conflict over the 80-metre length limit.

AUS-EC3-L1.2

The prerequisite, and the three routes in

This lesson sets out the mandatory prerequisite for the Engineer Class 3 near coastal and compares the three qualifying pathways: Engineer Watchkeeper, workshop skill equivalent, and MED 1 near coastal, including how holding a task book and a recognised trade certificate affects the sea-service requirements for each route.

AUS-EC3-L1.3

The task book, and why it halves your sea service

An AMSA task book is a structured record of competencies performed on board, signed off by a qualified person as you demonstrate them. It is not a diary and it is not a sea service letter. It is evidence that you can actually do the work, and the regulator pays for it in the only currency that matters to a seafarer: time.

AUS-EC3-L1.4

The two doors it opens

The EC3 near coastal opens two distinct pathways into the international STCW engineering hierarchy: a shortened route to Engineer Watchkeeper requiring 26 weeks of sea service, and a lesser-known route straight to Engineer Class 2 that demands the watchkeeper course but not the certificate.

AUS-EC3-L1.5

The Diploma, the oral, the medical and the renewal

This lesson sets out the four components needed to obtain and renew the Engineer Class 3 certificate: the Diploma qualification, the AMSA oral examination, a first aid certificate, and an AMSA form 1850 medical, including validity periods and the 120-day sea service renewal requirement.

AUS-EC3-M2-A Running the engine room, and running it alone Practice in examiner →

AUS-EC3-L2.1

Taking over and handing over the watch

An engine room watch is a continuous state of knowledge, not a shift. When you take it over you are inheriting everything the previous engineer knew, plus everything they meant to tell you and forgot. Your job at handover is to close that gap before you accept the watch, because the moment you accept it, it is yours.

AUS-EC3-L2.2

Unattended machinery spaces

This lesson covers the checks required before leaving an engine room unattended, the sensory discipline expected during rounds, and what genuine on-call readiness means for the duty engineer.

AUS-EC3-L2.3

The sole engineer

Working as the only engineer aboard removes the safety net of a team, and this lesson covers how to rebuild that redundancy through discipline, documentation, and training deck crew to act when you cannot.

5 lessons

AUS-EC3-M3-A Diesels, electrics and auxiliaries at 3000 kW Practice in examiner →

AUS-EC3-L3.1

The marine diesel — the cycle, and what actually breaks

This lesson explains how the four-stroke compression-ignition cycle works, how to read black, blue and white exhaust smoke as fault indicators, and why most diesel failures originate in the fuel, cooling, lubrication and air systems rather than the engine itself.

AUS-EC3-L3.2

Fuel oil and lubricating oil systems

This lesson traces the path of fuel from storage tank to injector and lube oil from sump to bearings, explaining how water and microbial contamination threaten both systems and what routine checks — draining, sampling, filter monitoring and oil analysis — keep them serviceable.

AUS-EC3-L3.3

Cooling water and seawater systems

This lesson covers how indirect cooling systems separate fresh water and seawater circuits, the ordered sequence of seawater-side components, the failure modes ranked by likelihood, and the correct step-by-step response when jacket temperature rises.

AUS-EC3-L3.4

Electrical generation, distribution and blackout recovery

This lesson covers how onboard electrical systems are arranged, how switchboard discrimination and paralleling work, and how to execute a structured blackout recovery sequence from initial notification through to restoring propulsion.

AUS-EC3-L3.5

Steering gear, bilge, ballast and the oily water separator

This lesson covers the four auxiliary systems most tested by surveyors and casualties: steering gear configuration and emergency operation, bilge system components and alarm requirements, ballast valve line-up and free-surface risk, and the oily water separator's legal and record-keeping obligations.

AUS-EC3-M4 · Chief on a Near-Coastal Ticket

3 lessons

AUS-EC3-M4-A Responsibility, compliance, casualty Practice in examiner →

AUS-EC3-L4.1

The chief engineer, and the relationship with the master

As chief engineer you own the machinery. Not the maintenance of it — the state of it. Whether it runs, whether it is safe, whether it will still be running at the end of the voyage, whether it complies, whether the people working on it are competent to do so. You do not get to say that nobody told you.

AUS-EC3-L4.2

Surveys, the certificate of operation, and the SMS

This lesson explains how the certificate of survey and certificate of operation define what an Australian domestic commercial vessel may do, how both must be satisfied alongside the crew ticket, what the chief engineer must prepare for survey, and how the SMS functions as a live operational and evidentiary record.

AUS-EC3-L4.3

Casualty below — fire, flooding, blackout, loss of propulsion

This lesson covers the four major engine room casualties — fire, flooding, blackout and loss of propulsion — setting out the priority actions for each and explaining why notifying the bridge is the critical first step before any engineering response begins.
