Work / Merchant marine job advice for a Polish citizen (Poland or other countries) [3]

I'm a Polish citizen currently living in Ireland and have been trying to start a career in the merchant navy. I don't have the education qualifications for Officer Cadetships so I am trying to find shipping companies that sponsor trainee ratings. Unfortunately, most of the ones in the UK and Ireland only take on cadets, and seem to draw their ratings directly from places like Eastern Europe or Asia.

If anyone here might have advice on the best way for a Polish national to find training to become a deck or engine rating, either in Poland or other countries, it would be a big help.

Dziękuję
