With qualifying sea service

What you need 
1) Recent qualifying sea service  
2) Evidence of your sea service and participation in required drills

1) Check your recent qualifying sea service  

You need either:

  • at least 360 days in the 5 years before you apply
  • at least 90 days in the 6 months before you apply.

Your sea service must:

  • be performing duties as a cook or in a food preparation role on board a vessel  
  • be completed while your Marine Cook certificate is valid.

We calculate sea service from the date we receive your application. For example, your 90 days must be within the 6 months before you apply.  

2) Provide evidence of sea service  

You will need to provide evidence of your sea service when you apply.  

You should provide your evidence using the STCW sea service template.

With other industry experience

You may be able to revalidate without qualifying sea service if you have performed duties or functions that AMSA considers equivalent to sea service.

You must provide a letter from your employer explaining:

  • your position
  • the duties and functions you performed
  • when and for how long you performed them
  • how the work maintained your professional competence.

AMSA will assess whether your duties or functions are equivalent to qualifying sea service.
