I take it, then you haven't read the STCW 2010 Manilla Amendments? Look at Regulation 1/11, revalidation of Certificates, and section A-1/11.
Regulation 1/11 para 1 says Every Master, Officer holding a Certificate issued to or recognized under the Convention OTHER THAN CHAPTER VI (which is MED training) who is serving at sea.........shall be required, at intervals not exceeding 5 years:
.1 meet the standards of medical fitness prescribed by Regulation 1/9, and
.2 establish continued professional competence in accordance with section A-1/11 of the STCW code.
Section A-1/11 says, seagoing service of 12 months in the previous 5 years or 3 months in the previous SIX MONTHS! (That's a change to watch for, right now it's 3 months in the previous 12.)
If you don't have enough sea service, you write an exam and do a MED refresher, same as it is now.
Do yourself a favour, don't heed rumours, pay no attention to "I heard that..." READ THE BLOODY BOOK!
Revalidation of certificates
1 Continued professional competence as required under regulation I/11 shall be established by:
.1 approved seagoing service, performing functions appropriate to the certificate
held, for a period of at least:
.1.1 twelve months in total during the preceding five years, or
.1.2 three months in total during the preceding six months immediately prior to
.2 having performed functions considered to be equivalent to the seagoing service
required in paragraph 1.1; or
.3 passing an approved test; or
.4 successfully completing an approved training course or courses; or
.5 having completed approved seagoing service, performing functions appropriate to
the certificate held, for a period of not less than three months in a supernumerary
capacity, or in a lower officer rank than that for which the certificate held is valid
immediately prior to taking up the rank for which it is valid.
