mistoo,
I'm older than you, and a friend who works for Bristows in Aberdeen asked someone there that question for me. She said they'd take me if I paid for my own IR. Of course the situation on the North Sea is changing frequently; she said before Sept 11th age might well not have been an issue at all. But it did sound as though if you can fund yourself for the lot you'd likely be in with a good chance. So good luck!
