AUS-EC1-M1 · The Ceiling

4 lessons

AUS-EC1-M1-A The top engineering ticket, and the four ways to reach it Practice in examiner →

AUS-EC1-L1.1

What it lets you do

This lesson sets out what an AMSA Engineer Class 1 certificate authorises, how its entitlement is bounded by propulsion type and kilowatts rather than gross tonnage, what Class 2 already permits, and why Australian yacht engineers hold a merchant ticket by default.

AUS-EC1-L1.2

Engineer Class 2 is a hard prerequisite

This lesson explains why Engineer Class 2 is an inescapable prerequisite for Engineer Class 1 under MO72, and traces the full certification ladder from Certificate of Safety Training through Engineer Watchkeeper and Class 2, including the two routes into Class 2 and the CoST rules that govern qualifying sea service.

AUS-EC1-L1.3

The four sea service routes

MO72 Schedule 2 gives Engineer Class 1 a single prerequisite certificate and **one of four** sea service options. Every route counts service performed **in charge of an engine room watch**.

AUS-EC1-L1.4

The superyacht problem

This lesson sets out why superyacht sea service towards an MO72 engineer certificate carries no guaranteed answer from AMSA, covering the power, propulsion, role and supervision tests, AMSA's discretion to discount service, and why written confirmation from the company must be secured from day one.

AUS-EC1-M2 · The Chief Engineer

3 lessons

AUS-EC1-M2-A Carrying the department Practice in examiner →

AUS-EC1-L2.1

The chief engineer's authority and the master

This lesson defines the boundary between the chief engineer's authority over machinery and the master's command of the vessel, covering decision-making responsibilities, the duty to give honest technical advice, standing orders, engine room logging, and the management of the engineering team.

AUS-EC1-L2.2

The ISM Code and the chief

This lesson explains what the ISM Code's safety management system demands of a chief engineer, covering planned maintenance, critical equipment, non-conformity reporting, and emergency preparedness, as well as the role of the DPA and the correct procedure for escalating a defect nobody wants to hear about.

AUS-EC1-L2.3

Budgets, dry dock and the long view

This lesson covers how a chief engineer owns and justifies the engineering budget, distinguishes operating from capital expenditure, manages spares and lead times, and builds a dry-dock specification that carries the department through the full class cycle.

AUS-EC1-M3 · Engineering at Depth

4 lessons

AUS-EC1-M3-A The competences that separate a chief from a watchkeeper Practice in examiner →

AUS-EC1-L3.1

Thermodynamics, efficiency and fuel consumption

This lesson covers the thermodynamics of marine diesel heat balance, how specific fuel oil consumption is measured and correctly interpreted, and the practical factors — hull fouling, trim, speed, generator loading and waste heat recovery — that determine where fuel costs actually arise.

AUS-EC1-L3.2

High-voltage systems and electrical safety

High voltage in the marine world conventionally means anything above 1000 V AC. Large yachts with diesel-electric or hybrid propulsion increasingly run HV distribution - 3.3 kV, 6.6 kV and above - and the day a yacht engineer first meets an HV switchboard is the day the habits of a low-voltage career become dangerous.

AUS-EC1-L3.3

Automation, control and alarm management

This lesson covers the principles and failure modes of PID control loops, the practical discipline of alarm flood and inhibition management, and the testing obligations for blackout-recovery automation aboard vessels with periodically unattended machinery spaces.

AUS-EC1-L3.4

Vibration, condition monitoring and predictive maintenance

This lesson compares run-to-failure, calendar-based, and condition-based maintenance strategies, then covers vibration spectrum signatures, oil analysis, thermography, ultrasound, and performance monitoring as practical tools for assessing machinery health before failure occurs.

AUS-EC1-M4 · When It Goes Wrong

3 lessons

AUS-EC1-M4-A Casualty, survey and the examination Practice in examiner →

AUS-EC1-L4.1

Major machinery casualty

There is one principle underneath all of it. **People, then ship, then plant.** An engineer who risks a life to save an engine has failed at the only part of the job that cannot be repaired.

AUS-EC1-L4.2

Surveys, class and the port state inspection

Two regimes sit on top of your machinery and they are not the same thing. **Class** is the classification society's own regime: it certifies that hull, machinery and systems are built and maintained to the society's rules.

AUS-EC1-L4.3

The AMSA oral examination

The oral is the last gate. Everything else - the Class 2, the sea service, the approved course, the short courses, the medical - is documentary. The oral is the only part where a human being decides whether you can be left alone with the plant and the department.
