The AEC (Approved Engine Course) is an MCA-recognised course designed to provide essential knowledge of marine diesel engines. It’s ideal for those working on vessels who need a basic understanding of engine operation and maintenance.

AEC is suitable for: Deckhands or stewards wanting engineering knowledge Skippers or crew of small commercial vessels Engineers starting in the marine industry Anyone interested in understanding marine engines

AEC1: Introduces the basic principles of diesel engines, systems, and maintenance. AEC2: Builds on AEC1 with advanced diagnostics, fault finding, and system integration, including electronic control systems. AEC2 is only available to those who have completed AEC1.

No prior mechanical experience is required for AEC1 – it’s designed for beginners. AEC2 does require successful completion of AEC1 or an equivalent qualification.

Each part of the course (AEC1 and AEC2) runs over five days, combining classroom theory with practical, hands-on training in our workshop.

AEC1 includes: 2- and 4-stroke engine operation Fuel, cooling, lubrication and electrical systems Basic fault finding and maintenance Safety and pollution control

Courses are delivered at Seagrass Marine HQ in Oban, fully equipped with engines, tools, and testing equipment for practical learning.

Absolutely. Inclusive and supportive training is something we are particularly proud of at Seagrass Marine. We know that people learn in different ways, and we are very happy to adapt how we teach where we can. This might include additional explanation or practice, information presented differently, extra breaks, a quieter environment, support with reading and written information, or simply taking a little more time with a particular part of the course. You do not need to have a formal diagnosis or use any particular terminology. If there is something you find difficult, something that helps you learn, or anything you are worried about, just let us know. We would much rather have that conversation and work out what will help. Where a course includes a formal RYA assessment or examination, there may be specific rules around reasonable adjustments and some arrangements may need to be agreed in advance. We will always do what we reasonably can to support you while ensuring the required assessment standard is met.
