Engineering Officers and Ratings
Information on how to gain a UK CoC for Engineering/Electro-Technical Officers or Engineering Watch Rating Certificate
Application process
In line with MIN 655, if you are applying for your first UK Certificate of Competency (CoC), you must post your application and original documents (except passport which must be an attested copy) at both NOE and CoC stages to:
Seafarer Certification 2/11
Maritime and Coastguard Agency
Spring Place
105 Commercial Road
Southampton
SO15 1EG
For all other applications, please email your application and scanned documents to engineering@mcga.gov.uk
Please ensure your documents are included as attachments or within a .zip folder. Unfortunately, we cannot open .rar extensions or links to file-sharing services (e.g. OneDrive, Google Drive, Dropbox etc).
Fast track requests
It is unlikely we will consider expediting a NOE (including Resit) or Rating application within our service standard of 28 days, or within 14 days for all other applications.
If you have been waiting longer than this and need us to assess your application on an urgent basis, please ask your company to email engineering@mcga.gov.uk directly with your full name, date of birth and a compelling reason (including the vessel joining date).
For NOE applications, your company must also confirm to us that you meet all of the certificate requirements i.e. the only barrier to gaining the certificate is you need to sit the MCA oral exam.
For NOE resits, it is unlikely we will be able to consider a fast-track request if you’ve already had 3 attempts or more.
Booking your MCA oral exam
Please email the following to onlineoralexams@mcga.gov.uk:
- your electronic NOE (paper NOEs need to be scanned colour copies in PDF format)
- scanned colour copy of non-UK subordinate CoC (for candidates appearing for a higher UK CoC at first instance) in PDF format
- scanned colour copy of your discharge book (front page and at least the last 2 years of sea time) as a separate PDF file
- an indication of your availability to undertake an online exam
EOOW and ETO candidates also need to provide scanned colour copies of the following exerts from your MNTB Training Record Book (TRB) in PDF format:
- page ‘i’ – contact details page
- section 2.2 – sea service record (page 11 of the 2018 edition 4 version)
- section 3.3 – particulars of ships (pages 23-25 of edition 4 for the first ship and each subsequent vessel)
Oral exam syllabuses
It is recommended that you review the relevant oral exam syllabus before sitting your MCA oral exam.
CoC requirements
If you pass your MCA oral exam, please see our guidance on the requirements for an engineering CoC application.
NOE resits
If you fail your MCA oral exam and wish to resit it, please email the NOE Fail to engineering@mcga.gov.uk. The fee is currently £159 and should be paid for online to prevent delays.
This process also applies if you passed your oral exam more than 3 years ago.
Unused NOE
If you were issued with a NOE over 5 years ago but did not sit the exam, the fee is reduced (currently £90). We’ll also need to see two forms of evidence showing 6 months’ seagoing service in the last 5 years.
Exemptions
All applicants will need to supply sufficient ‘detailed evidence’ of their course content for a 70% match to be obtained between their qualification and the MCA’s syllabuses. In addition applicants will be required to have obtained a pass mark of at least 50% in each of the individual subjects, within their qualification, being presented for the audit.
Copies of certificates, marking transcripts and photo ID, will need to be signed by a ‘notary’ confirming the true likeness to the original.

For those in the surface fleet, please see the Engineering Royal Naval Conversion Flow Chart. More information can be obtained directly from the Royal Navy (contact details on request).
If you are a Submariner, we are currently in discussions regarding routes taking into account your education, training and experience. We can raise your case directly with our examiner for review if needed; please email engineering@mcga.gov.uk with your Rank, service history and any relevant education and training.

CoCs are valid for 5 years. Fishing CoCs, MEOLs and Rating Certificates do not need to be revalidated.
Please see our detailed guidance on how to revalidate a UK CoC.
PSSR, EFA and MFA
Your UK CoC is proof that you have met the requirements for PSSR (A-VI/1-4), EFA (A-VI/1-3) and MFA (A-VI/4-1). There’s also no requirement to update these three courses. If an employer is querying this, please refer them to sections 3.25.1 and 3.35.2 of MIN 535 Amendment 1643.
Pre-August 1998 grandfather rights
If a seafarer had 6 months sea service prior to August 1998, they were not required to complete PSSR or EFA originally (as per section 2.4 of MGN 97).
‘First Aid at Sea’ certificate issued before August 1998 should be considered as equivalent to MFA (A-VI/4-1) as per MGN 147.
