I am not a North sea pilot but ATPLH and TRE, if you are going to work in The North Sea flying described to me as 99% sheer boredom and 1 % sheer terror. Plus you will be spending a lot of time away from your family, which given their current ages seeing them grow up is more important than being a glorified taxi driver at the moment.
I work on shore as with a varied job, currently long line lifting in The Peak District, can usually be found instructing, examining in the summer months with winter doing lifting jobs.
If you can afford it have a private one and go where you want to go when you want to go.
Have fun
