What does the Certification look like?

iymcs a6 certif

The custom-designed iymcs presentation folder type certification is stylish and practical. The presentation folder outer is made of real leather with a sythentic interior that is resistant to water and protects the certificates. It is A5 in size, it can hold up to four Certificates, and is an ideal size to be kept in a crew document case or with the boat's documents.

The iymcs Certificates are printed to ISO9001:2015 standards, are dual-language and feature extensive security features to security level 3 (Government passports & national Iidentification documents are security levels 1 & 2) and can be used as a personal ID in daily situations. (Nb. It cannot be used instead of a passport/national identity card).

The iymcs Deck Engineer 40GT™ course & certification appeals to crew members of all levels on a variety of vessels, whether they are operating or cruising, near-coastal, offshore or oceanic. The objective of the course is to enable crew to achieve a sound understanding of the workings of the engines & systems that are typically found on vessels up to 40GT.

There is a second aspect to this certification in that it can be used to work as an assistant engine room watchkeeper on tbe larger vessels under 35 metres, flag state permitting.

The course syllabus is extensive, both in the classroom theory and practical workshop exercises. It is assumed that you have very little knowledge of marine engineering and on-board systems. The course includes; the basic workings of the marine diesel engine, propulsion units, fuel systems, hydaulic systems, electrical systems, digital systems, domestic systems, fixed fire extinguishing systems, etc.

The course is designed to enable crew to be able to competently communicate with service engineers and technicians, and if necessary, undertake basic fault-finding and minor adjustments on-board under their remote supervision. Included within the course, is the basics aspects of health & safety, also covering other related issues including but not limited to MARPOL and deck related safe working practises (SWP). The teaching structure is interactive with the theory elements leading into the practical aspects.

Key aspects:

The iymcs Deck Engineer 40GT™ course course and certificate/endorsement is a great interactive course, with a logical step-by-step learning structure. The knowledge and confidence gained just by doing the course really makes you look at engines and systems found on-board in a very different way.

What is this?

Our Society, the 'International Yacht Marine Certification Society" (iymcs) operates its entire operations under a Quality Management System (QMS) that is in compliance with the International Standards Organisation (ISO) 9001:2015 amended. Part of this compliance involves full auditing procedures.
This is an important reference and enables us to gain recognitions from maritime administrations and marine industry bodies alike. The QMS together with the ISO, ensures that iymcs and its Members operate to the highest standards possible. All our courses, and more importantly the Certifications that we issue, are under ISO9001:2015.
This practice is most unusual for such courses and certifications. Some organisations will claim ISO:9001 adherence but often the reality is the ISO compliance is for a very small number of their courses.
