Medical fitness

To renew a certificate, you must provide evidence of medical fitness, including eyesight, hearing and speech, to the standards included in the STCW Manila amendments. This evidence must be provided as a valid STCW seafarer certificate of medical fitness carried out by an approved medical practitioner.

You must also meet fit and proper person requirements.


Sea service

You must provide evidence of having completed approved sea service for 12 months during the previous five years or three months in the six months immediately before renewal.

If you do not meet the sea service requirements, alternatives to sea service may be available. These may involve a practical competency assessment, further training or approved sea service and functions appropriate to the certificate held immediately before taking up the new rank.

MNZ is also able to accept appropriate experience in certain non-seagoing positions, if they are considered to be equivalent to sea service.
