Flag Administration CoC Processes:

When professional crew are applying for a job position on-board a vessel, their certifications are subject to a process of acceptance by the Flag Administration of the vessel.

It should be noted that there is no such thing as a globally accepted Certification of Competency.

Acceptance of professional CoCs are always on a case-by-case basis. It is very important that any professional CoC adheres as close as possible to the STCW Convention for watch-keeping.

As the Iymcs professional Certifications of Competency are restricted in their usage, the Flag Administration may consider the following to undertake:

1. Acceptance of the Iymcs CoC as is for the position on a particular vessel according to their manning scale requirements.

2. Iymcs CoC Endorsed by the Flag for their flagged vessels subject to any restrictions specified by the Flag.

3. Iymcs CoC is used to qualify for a Flag Administration issued STCW Coded CoC possibly subject to an oral examination.

4. Iymcs CoC is used to qualify as an entry qualification for a higher level CoC course(s).

Adheres to the STCW Code II/2 or II/3 on a case-by case basis subject to Flag acceptance or endorsement or recognition.

What does the Certification look like?

iymcs a6 certif

The custom-designed iymcs booklet type certification is stylish and practical. The booklet outer is made of real leather with a sythentic interior that is resistant to water and protects the certificates. It is A6 in size, ideal to be kept in a crew document case or with the boat's documents on the bridge.

The Iymcs Certificates are printed to ISO 9001:2015 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 Master 350GT/OOW 750GT™ power course and certification is a restricted Certificate of Competency (CoC) that has been configured to adhere as close as possible to the requirements for watchkeepers under the STCW Codes II/2 or II/3: Thus enabling a clear path to either recognition, acceptance or accreditation on a case-by-case basis by a Flag Administration.

What does a case-by-case basis mean?
When a seafarer applies for a management level position on-board a vessel of any type, as a Captain or Officer of the Watch, the vessel’s flag administration will make an assessment whether the seafarer is qualified to hold the position. An important aspect to this assessment is the STCW coding of the Certificate of Competency (CoC). It is only the Flag Administrations that can issue a coded STCW CoC and place them on the STCW Registry at the IMO.

The Iymcs Master 350GT/750GT power is not a coded CoC but is a CoC that adheres closely to the STCW code for watchkeeping: Due to this close adherence, when a holder of the Iymcs CoC is seeking a management position on a vessel i.e. Captain or OOW, the flag administration of that vessel can opt to do one of the following:

The Iymcs Master 350GT/OOW 750GT™ The Master 350GT/OOW 750GT™ power CoC can be configured for either Motor Yachts or Commercial Workboats.
There are several Endorsements that can be added at any time which is a significant advantage for many students or candidates who through future circumstances, may change to other types of vessels or to operate in other sea areas or oceans.

The Society has defined the CoC capacities as being 150Nm from a Safe Haven for crew working both on privately registered power vessels and commercially registered vessels for charter. This extends the operating radius to 300Nm in total. The operating restriction from Safe Havens can be lifted by undertaking the UnLimited OOW Ocean Astro Course and obtaining the Certificate of Proficiency (CoP).

The comprehensive subject matter covered in the Iymcs Master 350GT/OOW 750GT™ course has a good level of depth of knowledge which gives you a solid grounded knowledge base which is critical for crew wishing to progress to the upper-level certifications such as the Master 500GT. The course is heavily focused upon Safe Working Practises (SWP), Risk Assessments, Watch-keeping requirements, SOLAS, ISM & ISMS etc. Bridge Resource Management is undertaken with a focus upon bridge-team communications.

The diagram below shows the supporting ancilliary courses & certificates, as well as the the Endorsements that are currently available.

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 admininstrations and marine industry bodies alike. Our Society is ISO 9001:2015 certified by the British Standards Institute (BSI) Netherlands. 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 ISO 9001:2015.
This practise is most unusual for such courses and certifications. Some organisations will claim ISO:9001 adherence but often the reality is it is for a document management process or a similar back-office process instead of for actual operations and/or for Certification issuing.
