Application process

Please email your application and scanned documents to xxx@xxx.xx (mailto:xxx@xxx.xx)

Cadets should send their completed Training Record Book to:

Seafarer Certification 2/11Maritime and Coastguard AgencySpring Place105 Commercial RoadSouthamptonSO15 1EG

GMDSS applications should be sent to xxx@xxx.xx (mailto:xxx@xxx.xx)

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 xxx@xxx.xx (mailto:xxx@xxx.xx) 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 licence requirements i.e. the only barrier to gaining the licence 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

Information about how to book your oral exam will be emailed to you when you have met the requirements for an NOE.

Oral Exam Part A

From Spring 2023, the MCA OOW Unlimited, II/1, online oral examination will consist of the following elements:
- Part A: online computer-based proctored examination, and
- Part B: online face-to-face oral examination
Part A of the examination will be an integral part of the assessment for the MCA OOW Unlimited, II/1, Certificate of Competency (CoC). All OOW Unlimited, II/1, candidates with a first attempt Notice of Eligibility (NOE) issued from 1 May 2023 and all OOW Unlimited, II/1, candidates (including resits) with an NOE issued from 1 June 2023 must successfully complete Part A before being able to book Part B of the examination.

Further information can be found by accessing MIN 690 (https://www.gov.uk/government/publications/min-690-guidance-on-the-mca-oral-examination-booking-the-issue-of-notices-of-eligibility-noes-and-the-online-oral-examination-processes/min-690-guidance-on-the-mca-oral-examination-booking-the-issue-of-notices-of-eligibility-noes-and-the-online-oral-examination-processes). The accessibility statement for the Part A exam can be found at Accessibility Part A exam (https://assets.publishing.service.gov.uk/media/64b906d82059dc000d5d266a/V5_Widget_Completion_ReportV2.docx) (MS Word Document, 2.31 MB).

Oral exam syllabuses

It is recommended that you review the relevant oral exam syllabus (https://www.gov.uk/government/collections/seafarer-training-certification-examinations-and-careers#oral-examination-syllabuses) before sitting your MCA oral exam.

CoC requirements

If you pass your MCA oral exam, please see our guidance on the requirements for a deck CoC application (https://www.gov.uk/government/publications/coc-requirements/deck-coc-requirements).

NOE resits

If you fail your MCA oral exam and wish to resit it, please email the NOE Fail to xxx@xxx.xx (mailto:xxx@xxx.xx). The fee is currently £159 and should be paid for online (https://www.gov.uk/payments/seafarer-training-courses/noe-resit) to prevent delays.

This process also applies if you passed your oral exam more than 3 years ago.

Additional requirements for a third MCA Oral Exam attempt (or more)

From 3 July 2023, we will not be in a position to issue your NOE resit until we have received documentary evidence that you meet all of the CoC requirements (https://www.gov.uk/government/publications/coc-requirements/engineering-coc-requirements) (as per section 9 of MIN 690 (https://www.gov.uk/government/publications/min-690-guidance-on-the-mca-oral-examination-booking-the-issue-of-notices-of-eligibility-noes-and-the-online-oral-examination-processes/min-690-guidance-on-the-mca-oral-examination-booking-the-issue-of-notices-of-eligibility-noes-and-the-online-oral-examination-processes#resit)). Please send scanned copies of these documents by email to xxx@xxx.xx (mailto:xxx@xxx.xx) when you apply for your NOE resit.

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 (https://www.gov.uk/payments/seafarer-training-courses/application-for-noe-resit-unused)). We’ll also need to see two forms of evidence showing 6 months’ seagoing service in the last 5 years.

Royal Navy conversion to Merchant Navy

We have a Memorandum of Understanding with the Royal Navy, giving a route to Merchant STCW Certification based on the education and training, as well as experience, gained whilst in the Navy.

For those in the surface fleet, please see the Deck Royal Naval Conversion Flow Chart (https://www.gov.uk/guidance/uk-seafarer-careers-training-provision-and-information#royal-naval-mous). 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 us your Rank, service history and any relevant education and training.

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 5.1 and 5.2 of MIN 643 (https://www.gov.uk/government/publications/min-643-m-maritime-and-coastguard-agency-mca-short-course-approval-process-guidance).

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 (https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/282315/mgn097.pdf)).

‘First Aid at Sea’ certificate issued before August 1998 should be considered as equivalent to MFA (A-VI/4-1) as per MGN 147 (https://www.gov.uk/government/publications/mgn-147-approval-of-crew-agreements-merchant-ships).
