Psychiatrist registrar in Ireland

I would like to know what a Dr has to do to become a psychiatrist in Norway?
I have tried to look through the internet, but have not been able to find the qualifications needed to work in Norway as a specialist in psychiatry.
Could i train in Ireland and then transfer it to Norway to keep on working in Norway?
Could you please help me?
Best regards,
Dr Katharina Henkelmann
