MCA Approved Engine Course 1 (AEC 1)

The MCA Approved Engine Course Part 1 (AEC 1) is aimed at giving a wide and general appreciation of basic marine diesel mechanics and electrics and also an understanding of the Chief Engineer’s responsibilities.
The course is the first level qualification for the MCA Engineering Officer training scheme. It is seen as the first rung on the engineering ladder for those with no formal marine engineering experience and is an ideal introduction for those who wish to improve and enhance their employment prospects in the various aspects of the marine industry e.g.

• The super yacht industry
• Commercial vessels
• Marine support offshore wind farms
• Private boat owners

This course can also be undertaken by any crew member: deck, stewards and chefs who wish to advance their employment prospects in this extremely competitive market place by being able to fill the Assistant Engineer position, or who simply wish to develop their engineering knowledge.

Having obtained the MCA Approved Engine Course 1 certificate, it offers up the opportunity to fill the position of:

• Chief Engineer on sailing yachts over 24m in length and less than 200gt and 750 Kw within 60 miles from a safe haven
• Chief Engineer on motor yachts over 24m in length and less than 200gt and l500Kw within 60 miles from a safe haven
• Act as the Assistant Engineer on vessels over 200gt within 60miles from a safe haven (under the Large Yacht code LY(2)

See MCA MGN 156(N) Annex A for more details of qualifications and manning requirements

The five day course is instructed by an experienced Super Yacht Marine Engineer who is thoroughly professional, conscientious and uncompromising in his approach to engineering and safety responsibilities. He has a track record of achievement both in the commercial super yacht business and as a Marine Engineering Officer within the Royal Navy, having completed 29 years within the service.

The course includes practical sessions as well as all the theory requirements and will cover:

• The principles of two and four stroke engine operation
• Construction of engines
• The role of air in the combustion process
• The fuel system
• The cooling system
• The lubrication system
• Engine electrical systems
• Power transmission
• Hull fittings
• Fault finding and rectification
• Safe working practices
• Bottled gas installations
• Pollution prevention

To complete the course you must be at least 18 years old.  If you have no engineering experience or qualifications we recommend that you complete the one day RYA Diesel Engine Course first.

All equipment to complete the course will be provided. You just need to bring a pair of overalls and suitable footwear.

A Course Completion Certificate will be awarded provided the student has attended for the full 5 days.

Tea and coffee is provided and you can get lunch from the Deck Cafe in the marina or the village which is a short walk away. Alternatively you can bring a packed lunch to eat in the classroom.
