Diploma in Marine Engineering Class 3 and Class 4 Level 6
Why Study Marine Engineering at NMIT?
1. Internationally relevant maritime training
The programme contributes to training requirements associated with the internationally recognised STCW Officer in Charge of an Engineering Watch Class 3 certification.
This can support a career working aboard merchant vessels internationally, subject to meeting all Maritime New Zealand certification, sea-time, medical, eyesight and examination requirements.
2. Strong practical focus
Marine engineering is not simply classroom-based engineering.
Students develop knowledge and practical capability relating to:
- Main engines
- Auxiliary machinery
- Electrical systems
- Electronics
- Control systems
- Ship construction
- Engine-room watchkeeping
- Workshop skills
- High-voltage systems
- Safety and emergency procedures.
3. Marine simulators and specialist facilities
NMIT's International Maritime Institute has specialist facilities including Kongsberg Marine Engineering and Navigation simulators.
This gives students an opportunity to develop skills in a controlled training environment before applying them in real maritime operations.
4. Blended learning
NMIT specifically describes the programme as offering a blended delivery model, combining online and in-person learning.
Some components can be completed online, which can reduce the amount of time students need to be away from employment.
5. Merchant navy career pathway
The programme prepares students for marine engineering work on vessels of varying sizes and propulsion power.
NMIT states that the qualification provides marine engineers for the international and domestic maritime industries.
6. Fishing-industry pathway
The Class 4 component can provide a pathway toward working as a Chief Engineer on fishing vessels with maximum propulsion power of 3,000 kW, subject to the relevant MNZ requirements.
7. Further progression
NMIT states that the diploma provides a pathway into Level 7 programmes leading towards Marine Engineer Class 2 and Class 1 (MEC2 and MEC1) qualifications.
Disciplines / Specialisations
The programme effectively covers two major maritime engineering pathways:
Marine Engineer Class 3 – MEC3
This is associated with the internationally recognised:
STCW Officer in Charge of an Engineering Watch
and is intended for engineering officers working on merchant vessels.
Marine Engineer Class 4 – MEC4
This is associated with the domestic/fishing industry pathway and can lead towards Chief Engineer duties on vessels with maximum propulsion power of 3,000 kW, subject to MNZ requirements.
Career Outcomes
Graduates can pursue careers in the maritime industry, including roles such as:
- Marine Engineer
- Engineer Officer of the Watch
- Marine Engineering Officer
- Ship Engineer
- Engine-Room Engineer
- Marine Engineering Technician
- Fishing-vessel Chief Engineer, where the relevant Class 4 requirements are met.
Merchant Navy Career
The Class 3 pathway can prepare students for work as an engineering officer on merchant ships.
Potential vessel types can include:
- Cargo ships
- Container vessels
- Tankers
- Passenger vessels
- Other merchant vessels.
Visa Requirements
For an international student paying the NMIT international tuition fee, the usual visa route is the
Fee Paying Student Visa
Immigration New Zealand states that this visa is for students paying international tuition fees themselves or through:
- Family support
- Loans
- Scholarships
- Other accepted funding arrangements.
Main requirements include:
- Offer of Place from NMIT
- Evidence of tuition funding
- Evidence of living expenses
- Acceptable medical/travel insurance
- Good health
- Good character
- Genuine intention to study
- Evidence that the student can leave New Zealand at the end of their stay.
Practical Training and Visa Work Rights
This programme has an unusual situation because it involves maritime practical/sea-service requirements.
Immigration New Zealand states that where practical work experience is a required part of the course, students can provide evidence from the education provider and the required practical experience can be treated differently from ordinary employment hours.
Students should therefore obtain written confirmation from NMIT regarding:
- Required sea service
- Whether a particular placement is compulsory
- Documentation required for the visa
- Whether the activity qualifies as required practical work experience.
