Guidance

Approved Engine Course 1 Guidelines

Published 1 February 2020

1. General

All new AEC 1 Course approvals and re-approvals must be undertaken in accordance with these guidelines. These guidelines confirm a change in the mandatory minimum hours for the AEC course. The total running time of the AEC course must now include the assessment and must be at least 35 hours. Previously minimum course time was set at 30 hours. However, this did not include assessment. Existing courses should now transition to the new requirements within six months of this document being published (by 02 September 2020). A desk top submission should be sent for approval to your local Marine Office or in the case of overseas training providers, the Seafarer Training and Certification Branch. This should demonstrate changes in your procedures and course content to meet the new requirements. If you are unable to transition within this period then you should write to the Chief Examiner (stc.courses@mcga.gov.uk) providing a valid explanation and action plan for your transition.

This training is relevant to wide ranges of personnel that require the knowledge and understanding to build up a career as an Engineer of a Small Vessel.

The Approved Engine Course 1 (AEC 1) is a Non- STCW certificate. This is issued directly by Maritime & Coastguard Agency (MCA)-approved training providers. The training is a prerequisite to obtaining a Marine Engine Operators License. While the MCA recognises these qualifications, it cannot guarantee recognition internationally. Holders of these certificates should check the certification requirements of the local Port State Control Administration prior to entering their jurisdiction.

The AEC 1 basic theoretical learning and relevant practical hands on trainings course, provides base foundation for Small Vessel engineers from the course participants and enable students to carry out regular servicing of onboard machinery/equipment by developing a greater understanding of possible faults before they develop into major problems.

2. Aim of the course

The aim of this course is to provide students with the basic theoretical knowledge and some practical hands on experience of diesel engines and systems to enable them to meet the requirements of the MCA Codes of Practice for the Safety of Large Commercial Sailing & Motor Vessels, the Safety of Small Commercial Motor Vessels and the Safety of Small Workboats & Pilot Boats. This course is also aimed to address the following reference areas:

1. Annex 5 of the Safety of Large Commercial Sailing & Motor Vessels Code defines the Engineering Competencies required for these vessels.
2. Annex 7 of the Safety of Small Commercial Motor Vessels Code defines the Engineering Competencies required for these vessels.
3. Annex 11 of the Safety of Small Workboats & Pilot Boats Code defines the Engineering Competencies required for these vessels.
4. Certain defined circumstances require that: “One of the persons (employed aboard) … should be familiar with the operation and maintenance of the main propulsion and associated machinery of the vessel and should have attended a suitable course.”

Note: This short course does not attempt to make diesel engineers from the course participants but should enable students to carry out regular servicing and be more aware of possible faults before they develop into major problems.

The course also aims to give the basic training to the engineer officers who want to pursue a career on “Small Vessels” (Fishing Vessels, Yachts, Tugs, Workboats, Standby, Seismic Survey, Oceanographic Research Vessels and Government Patrol Vessels). The necessary training outlines the certification structure, examination and training requirements. It also explains the regulatory requirements regarding the implementation of intended training elements, as may be applicable.

The overall aim is to provide Small Vessel engineers with the necessary knowledge, understanding and proficiency to carry out safe and effective operations onboard.

3. Background of the course

Article IX of the STCW Convention allows an administration to adopt alternative arrangements of education and training for special types of ships and trades. The MCA has utilised this alternative arrangement to create a certificate structure for this course.

This document includes the criteria for the development of courses to deliver training for service on ships.

4. Health and safety: conduct of training

At all times the safety of learners and staff delivering training must be ensured.

Practical exercises should be designed and delivered solely to meet the course criteria.

All training centres must adhere to applicable regulations made under the Health and Safety at Work Act 1974, as amended, and take proper account of the advice given in associated guidance documents and ‘Approved Codes of Practice’. Outside the UK, training centres must adhere to relevant national legislation and have a routine inspection to ensure a safe working environment for students broadly equivalent to the UKs standards (Health and Safety at Work Act 1974).

Training centres are required to make assessments of any potential risks to the health and safety of staff and learners that may be associated with their activities. They are also required to identify, implement, monitor and review effective measures for minimising and controlling risks.

Centres are required to make effective arrangements for dealing with any emergency, incident or accident that may occur during the training course. In the UK, the foregoing is required in accordance with the Management of Health and Safety at Work Regulations 1999, as amended.

Centres must draw up their own safe working procedures to meet statutory Health and Safety obligations.

5. Training structure

Approved Engine Course (AEC) is divided in two parts, AEC I and AEC II. The previous AEC is modified to AEC I. The AEC 2 is an enhanced continuation with the delivery of approximately 50% practical tasks and half (50%) theory. The AEC part I and part II will be termed as the full AEC. The scope of these guidelines is limited to AEC 1 only.

Centres will need to develop a training programme covering the AEC 1 syllabus requirements and then submit their training plans to commence approval process. Approvals within the UK should be directed to the local Marine office. Outside of the UK approval requests must come to the Seafarer Training and Certification Branch (STC.Courses@mcga.gov.uk).

The training plans must define education and training objectives and related standards of competence to be achieved. The levels of knowledge, understanding and skills appropriate to the assessments required under these criteria are required to be identified.

The training should be structured around the outcomes although centres should devise their own training schedules and detailed lesson plans to ensure effective and logical delivery of the subject matter and achieve the objectives of the training.

6. Training day and training duration

A training day is defined as one which has no more than eight contact hours and cannot be in excess of 10 hours, including relevant breaks.

The training shall be not less than 35 contact hours and will be delivered as a stand-alone module.

7. Entry requirements

1. Minimum 18 years of age.
2. There is no entry qualification specified to join this course.

8. Instructor to learner ratio

The instructor to learner ratio should not exceed 1:24 for non-practical sessions and 1:8 for practical sessions. However, an Approved training provider may raise this to 1:10, if they can complete a risk assessment to ensure that, there is adequate equipment for all candidates to work simultaneously and all training outcomes can be monitored and assessed.

The training centre, having due regard to health and safety and the objectives of the training, should determine other staffing requirements.

9. Qualifications of instructors and assessors

Instructors and assessors are required to be qualified in accordance with the requirements of Regulation I/6 STCW. Guidance on relevant qualifications & experience required to deliver & assess the training is given in Annex C.

10. Facilities and equipment

Training centres seeking approval will need to demonstrate availability of suitable facilities for practical, general and theoretical instruction, appropriately equipped with teaching and learning aids and designed to enable each learner to fully engage, in the learning process.

All facilities must be maintained and where appropriate, inspected and tested in accordance with applicable regulations, current standards and manufacturers recommendations.

A classroom or equivalent must be provided for general instruction and the theoretical aspects of the course, to include suitable presentation facilities and audio-visual aids (e.g. DVDs, posters, diagrams).

Sufficient and suitable equipment must be provided to enable practical sessions and assessment of learning objectives.

A list of recommended equipment is given in Annex B, for guidance. The training centres may to use additional or similar equipment, as considered to be suitable, to deliver their training course.

11. Assessment requirements

Assessment must be organised so that learners can, through demonstration and examination, show that they meet the competences stipulated, as identified in the AEC 1 syllabus.

The assessment system, methods and practice must be valid, reliable and authentic.

Each learner shall receive an assessment plan at the start of the training.

The assessment system should support appeals made by learners against assessment decisions.

A variety of sources of evidence may be used and must include evidence of learners’ ability to meet the criteria for evaluating competence.

A range of direct observation, oral questioning, simulation and role play are considered ideal approaches to generating much of the evidence required.

All assessment must be formally documented and be made available for verification audits.

The practical exercises must be conducted, and achievement of competency must be assessed throughout the course under the supervision of the instructor. The end of week assessment must be marked by an independent appropriately qualified person (same requirements as set out in Annex C).

12. Certification

On achievement of the desired standard of competence, a certificate will be issued by the centre in the MCA approved specimen certificate format, as given in Annex D.

13. Course outcomes

NOTE: Fault finding, and rectification will be discussed in each part of the syllabus as the individual topics are covered.
