Irrespective whether you have done STCW 2010 Courses or not, certain Merchant Navy Courses in India and Personal documents needs to be renewed for COC Revalidation.
An addendum - got may very upgraded to 2010 requirement. I was asked to apply through the institute where I did my reval and refresher courses. Need medical not older than 6 months. Self attest all documents. It takes only 2 days in Mumbai. All the best. Please update accordingly. Thanks. Deep Dsouza.
One more thing- go there at 1000 and submit your COC. Take copy of page where it is written for extension of lisence. Sign that page and submit at counter no.1. She will call you back at 1300. By 1310 we had finished and was out of the MMD.
