    Program Courses

    This year's courses are still under development. Showing 2017's courses for reference.

    Students apply electrical and electronic principals to tasks such as electrical system diagnostics, servicing batteries, working with lighting circuits and guauges, and maintaining harnesses and accessories.


    • SECU1194G

    Students acquire knowlege of hydraulic principals and build on those basics to troubleshoot, service and repair hydrailic systems. This course enables the student to apply the principles of pressure, volume, and fluid direction while acquuiring hands-on experience with reservoirs, coolers, strainers and hydraulic accumulators.


    • SECU1194G

    The purpose of this course is to refresh skills in mathematics developed through secondary programs in areas deemed essential for the successful completion of the program. Although the topics covered in this course are common to any math program, every effort is made to illustrate their usage in the trades’ professions.

    Students focus on the marine aspect of diesel power, with special attention to skill development regarding belt and chain operating systems, marine transmissions and marine clutches.


    • SECU1205
    • SECU1194G

    Students demonstrate the ability to identify marine system components and parts including bearings, seals, lubricants, cooling systems, and fuel systems. Students are introduced to these engine operating systems and air induction and exhaust systems from a troubleshooting and repair perspective. They acquire knowledge regarding engine principles, cooling systems, air filtration and exhaust systems, and diesel fuel systems to carry out engine and engine support system servicing tasks.


    • SECU1205
    • SECU1194G

    Students are introduced to the skills required for marine engine removal, disassembly, rebuilding and installation using small engines as a starting point.


    • SECU1194G
    • SECU1205
    • MMMN1011

    Students use their knowledge of engine operating systems and air induction and exhaust systems to tear down and reassemble diesel engines from a troubleshooting and repair perspective. They use knowledge regarding engine principles, cooling systems, air filtration and exhaust systems, and diesel fuel systems to carry out tear down and re-assembly tasks.


    • MMMN1022
    • SECU1194G

    In this course, students exhibit skill in applying the proper methods for disconnecting, removing, installing and re-connecting engines. They test the engines and evaluate the success of their endeavors in the shop.


    • MMMN1011
    • MMMN1023
    • SECU1194G

    This course provides an introduction to the meaning of community service.  Students learn how community service can enhance a student’s educational experience, personal growth, employability, and civic responsibility. Students participate in one day of volunteering to enhance their understanding of civic responsibility and to help the New Brunswick Community College realize its vision of transforming lives and communities. 

    In this course, students focus on applying communication skills in reading, writing, speaking, document use, and critical thinking to make occupation-specific communication effective and efficient while developing computer-related skills necessary to be successful in college and on the job.

    In this course, students focus on acquiring job search skills to gain a work-term placement as well as employment while also, developing interpersonal communication skills needed to grow their career.

    This course is designed to provide students with the skills to sketch and read blueprints to extract information. Students learn to interpret information from blueprints and use proper instruments and techniques to produce drawings.

    This is a 1-day environmental awareness training course based on Environment Canada's "Code of Practice for Reducing CFC/HCFC/HFC Emissions in Refrigeration and Air Conditioning Systems". It is suitable for residential, commercial, industrial, domestic, automotive and mobile applications. Specific topics covered are: CFCs and the ozone layer, isolation valving, recommended components, leak detection methods, system charging procedures, special maintenance provisions, and refrigerant recovery, reuse, recycle and reclamation equipment.


    • SECU1194G

    This course is intended to provide the students with the knowledge required to function safely in their work environment. Included within this course are the specific WorkSafeNB competencies required for all NBCC graduates. Participants cover the safety and security standards required on the job so that they are aware of potential hazards and can prevent them.

    The safety procedures introduced in the course focus on preparing the students to function efficiently and safely as they get more practice and applied knowledge specific to their trade.

    This course is designed to equip the students with the skills required to recognize, use, and maintain the tools of their trade from the perspective of organization, efficiency, and safety. They cover basic shop tools and equipment including hand and power tools, fasteners, tubing, and fittings.


    • SECU1194G

    This course introduces students to the safe use of rigging, hoisting and lifting equipment.


    • SECU1194G

    This course provides students with an understanding of:

    - their responsibilities when working in areas where fall hazards exist;

    - the use of and inspection of the required equipment; and

    - the critical controls necessary to reduce the risk of a fall.

    This course provides students with an understanding of the hazards related to working in a confined space environment. It looks at the proper safe work practice and procedures for confined spaces as well as rescue considerations.

    The purpose of the practicum is to provide students with a direct, supervised practical experience. Such an experience enables students to apply the knowledge acquired during their training directly to their field of study. The practicum experience exposes the students to the trade environment and participants are expected to become members of the team in the industry site to which they are attached.

    Upon completion of this course, the students will be able to perform cutting, brazing and basic arc welding operations. Instruction includes the safe practices and accepted methods of oxy-acetylene and electric-arc welding equipment use.

    Specific Considerations

    Although marine in name and nature, many units of instruction are accredited by other mechanical trades. Numerous graduates of the Marine Diesel Mechanics program also find employment in heavy equipment, truck, and transport repair. The Marine Diesel Mechanics program shares a number of courses with the Heavy Equipment Service Technician and Truck and Transport Service Technician programs.

    Safety boots, coveralls and a toolkit are required. Approximate costs are $1,000.

    Most of your classes are scheduled to take place between 8:30am and 4:30pm Monday to Friday, however, some required classes may be scheduled during evening hours.
