This marine engineer job description template is designed to reflect Australian workplace standards and maritime industry practices at the time of publication. Confirm the applicable modern award for your business and ensure compliance with all relevant employment and maritime safety laws. It does not constitute legal, HR, or professional advice and should not be relied on as a substitute for advice specific to your business, workforce, or circumstances.

About the marine engineer role

A marine engineer officer operates and maintains a vessel’s main and auxiliary engines, machinery and power systems, keeps engine-room watch, and carries out planned maintenance and fault repair to keep the ship running safely at sea. The role combines hands-on mechanical work and diagnostics with system monitoring, safety compliance and supervision of engine-room ratings.

In Australia, marine engineers on offshore vessels are typically covered as engineer officers under the Maritime Offshore Oil and Gas Award 2020 (MA000086). This award uses eight vessel schedules and aggregate annual salaries, so the classification and pay depend on the vessel type and the engineer’s certificate of competency.

This template provides a foundation for creating clear, compliant job descriptions that attract qualified engineer officers while setting appropriate expectations for the role. Once crewed, manage your swing rosters efficiently with rostering software.

Key responsibilities

Core duties included in this job description template

Engine operation

Operating and controlling the vessel's main and auxiliary engines and machinery, including propulsion, generators, pumps and steering gear, throughout the voyage.

System monitoring

Monitoring propulsion and power systems, fuel and cooling systems, alarms and control panels, and adjusting settings to maintain safe and efficient operation.

Planned maintenance

Carrying out scheduled planned maintenance on engines, machinery and equipment, and recording work in the vessel's maintenance system.

Fault diagnosis and repair

Diagnosing mechanical, electrical and hydraulic faults, carrying out repairs at sea, and escalating major defects to the chief engineer promptly.

Fuel and lube management

Managing fuel, lubricating oil and consumables, monitoring bunkers, and following procedures for bunkering, transfers and record keeping.

Watchkeeping and supervision

Standing engine-room watch, following safety and MARPOL environmental requirements, and supervising and directing engine-room ratings during operations.

Skills and attributes

What to look for in candidates

Mechanical aptitude

Strong hands-on skills in operating, maintaining and repairing marine engines, machinery and associated systems.

Fault diagnosis

Ability to systematically troubleshoot mechanical, electrical and hydraulic faults and carry out effective repairs at sea.

Safety awareness

Consistent compliance with marine safety, STCW and MARPOL requirements, and alertness to hazards in the engine room.

Team leadership

Confidence supervising and directing engine-room ratings and coordinating with deck and bridge crew.

Watchkeeping discipline

Reliability to stand engine-room watch, respond to alarms promptly and work safely during long swings at sea.

Physical fitness

Capacity for physically demanding work in confined, hot and noisy engine spaces, meeting offshore medical and fitness standards.

Qualifications and requirements

The qualifications for marine engineer positions are certificate-based and depend on the vessel type and the level of engine-room responsibility. Some are mandatory, while others are preferred or desirable.

  • AMSA Certificate of Competency (Required)

    A current AMSA Certificate of Competency (Marine Engineer) appropriate to the vessel and role

  • STCW certification (Required)

    Valid STCW basic safety training and any additional STCW certificates required for the vessel

  • Working rights (Required)

    Eligibility to work in Australia

  • Offshore medical (Required)

    A current seafarer or offshore medical certificate meeting fitness-for-duty standards

  • Offshore vessel experience

    Previous engine-room experience on offshore or supply vessels is advantageous but not always essential

  • Additional safety tickets

    Offshore survival, sea survival or firefighting tickets are desirable depending on the vessel and operation

Working conditions

Set clear expectations for candidates about the work environment

  • Swing rosters with extended periods living and working on board offshore
  • Physically demanding work in confined, hot and noisy engine spaces
  • Engine-room watchkeeping, including nights and weekends at sea
  • Compliance with marine safety, STCW and MARPOL requirements
  • Use of personal protective equipment and offshore safety procedures
  • Time away from home for the duration of each offshore swing

Award coverage

Understanding the Maritime Offshore Oil and Gas Award

Maritime offshore oil and gas award 2020

Marine engineers working on offshore vessels are covered as engineer officers by the Maritime Offshore Oil and Gas Award 2020 (MA000086). This modern award sets minimum pay, allowances and conditions for crew on vessels servicing offshore oil and gas operations.

Unlike hourly-rated awards, MA000086 uses eight vessel schedules and aggregate annual salaries, with overtime rolled into the salary rather than paid separately. Because of this structure, refer to the Maritime Offshore Oil and Gas Award guide for current figures rather than quoting hourly rates. Note that the rig and production workforce is instead covered by the separate Hydrocarbons Industry (Upstream) Award (MA000062).

Certificates, swings and salary structure

Marine engineer roles require a current AMSA Certificate of Competency (Marine Engineer) and valid STCW tickets appropriate to the vessel, so classification is tied to certification and vessel type. Offshore crews typically work swing rosters — set periods on board followed by set periods off — rather than standard weekly hours.

Because aggregate annual salaries under MA000086 already incorporate overtime and many penalties, confirm the vessel schedule that applies and check whether an enterprise agreement applies in place of the award. Use award interpretation software to keep pay and rostering aligned with the correct instrument.

Frequently asked questions

  • A marine engineer officer operates and maintains a vessel’s main and auxiliary engines, machinery and power systems, keeps engine-room watch, and carries out planned maintenance and fault repair to keep the ship running safely at sea. On offshore vessels they also manage fuel and lubricating oil, follow marine safety and MARPOL requirements, and supervise engine-room ratings. It is a hands-on, certificate-based role combining mechanical work with system monitoring and safety compliance.

  • Marine engineers working on offshore vessels are typically covered as engineer officers by the Maritime Offshore Oil and Gas Award 2020 (MA000086), which sets pay, allowances and conditions for offshore crew. The rig and production workforce is instead covered by the separate Hydrocarbons Industry (Upstream) Award (MA000062). Some businesses may be covered by an enterprise agreement, so always confirm which instrument applies.

  • Unlike hourly-rated awards, the Maritime Offshore Oil and Gas Award (MA000086) uses eight vessel schedules and aggregate annual salaries, with overtime rolled into the salary rather than paid separately. Because of this structure, refer to our Maritime Offshore Oil and Gas Award guide for current figures rather than quoting an hourly rate, and confirm the vessel schedule that applies to your operation.

  • It’s not legally required, but indicating the salary structure can attract more applicants and set clear expectations. Because offshore engineers are paid aggregate annual salaries, you can reference the applicable vessel schedule or use phrases like ‘aggregate salary as per award’ or ‘competitive offshore package based on certificate and experience.’ See our Maritime Offshore Award guide for guidance.
