Hi PhDMechEng! I have two supervisors although until recently was only dealing with my principle one, however I found I needed another perspective on my project and my second supervisor was able to contribute really useful information. It also helps if you have any queries regarding your work - two opinions is very useful! The only problem that might potentially appear are if they have conflicting ideas regarding your project but overall I'd suggest having a second supervisor is well worth it! Good luck in the PhD!

I've been studying my PhD now for a year and a half and although I have 2 allocated supervisors, I only see one of them (which is very regularly) but I never see the other one at all and he has absolutely no input into my PhD . He would be there if I had major problems but couldn't help with any of my degree work as he works in a completely different field - obviously I know this is good as there can never be any conflicts between them but is it okay to have just one supervisor overseeing the PhD? Any suggestions are welcomed! Thanks
