What does the Certification look like?

iymcs a5 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).

Under the STCW and GMDSS Conventions, it is a requirement for all crew to be qualified as a Radio Officer or hold either the ROC (Restricted Operators Certificate) or the GOC (General Operators Certificate), to enable them to operate GMDSS Radio Equipment carried on-board commercial vessels, fishing vessels, classic sail vessels or super-yachts engaged in charter. This requirement is a fundamental principle of the SOLAS Convention.

The iymcs Radio GMDSS Restricted Operators Certificate (ROC) + SatCom course covers the training requirements for the Restricted Operators Certificate holders operating in Sea Area A1. In addition, the syllabus has been extended to cover MF requirements for Sea Area A2 as well as incorporating the syllabus for GMDSS L-Band Satellite operations of Inmarsat C and Iridium GMDSS.

The reasons for this are:

1. Many of the private-registered super-yachts under 300GT, operate regularly in Sea Area A1 & A2. They often carry L-Band Satellite and some, Marine SSB MF/HF Radio Telephones.

2. The Search & Rescue Regions of some Maritime Administrations are so big that often the Sea Area A1 is not designated. That is to say, in many coastal regions, they are designated as Sea Area A2 from a coastline. The communication distances within these sea areas are often beyond the DSC Tx/Rx range capabilities of the Marine Radio VHF.

3. Satellite communications play a significant part in Distress & Urgency situations once beyond Marine VHF range.

4. There are sea areas that experience very poor sea conditions and meteorological conditions on a regular basis. In such sea areas, communications via Marine VHF can often be limited to a short horizon distance of just 4 Nm to 5 Nm. Marine SSB MF and/or L-Band Satellite is essential to extend communication ranges of both voice and DSC.

This comprehensive course focuses upon; the SOLAS requirements, GMDSS organisation and structure, the 7 elements of GMDSS, comms protocols & phrases, the operating procedures for Distress, Urgency & Safety communications, Medical communications, SAR organisation and radio equipment & maintenance.

The subjects are covered in-depth and the operating procedures are shown with scenarios and responses to, focusing upon SOLAS requirements.

Certification Structure:
This Certificate is principally a Course Completion Certificate, it needs to be presented to the Flag Administration of the vessel and it’s radio station, for them to issue their own Restricted Operator’s Certificate or issue an Endorsement to this Certificate.

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.

How much does the course cost?

The following are the recommended iymcs course prices (ex.VAT), prices may fluctuate between Member schools & colleges.

Scandinavia 750,-EUR Northern Europe 650,-EUR United Kingdom 600,-GBP
Southern Europe 550,-EUR Middle East 650,-USD North America 490,-USD
Prices exclude: course books,certification costs,personal traveling costs,course food and course accommodation.
