Calum,
I have just started back as a roughneck after a few years out. (first positive)
The company I work for have/will build 3 x Nclass jackup rigs, all Norwegian spec between now and the end of the year (second positive)
The first rig (mine) has just crewed up with 8 brand new green hand roustabouts (deck crew) out of 16. (third bonus)
So, I would send an email and letter to(HR MGR, Rowan Drilling UK, Peterseat Drive, Altens) asking for a job as a roustabout, explaining your construction background etc.
I would though book your BOSIET + Medical now. 650 + 120
MIST training is compulsary now but if you book through petrofac, they will do it for 21 quid !! usually 400.
So thats the drilling contractor
In the meantime, send yoru CV to all the agencies as well.
RGB
Northlandic
Global Resources
Interservices
etc etc, search for them
You have to do your course, apply and apply and apply, call them each week and keep on trucking !
Good luck
