I will say, unless you have a related trade to offshore it can be difficult to get a foot in the door. Ive a mate thats been tryin years! I served my time as a Mechanical Hydraulic tech at an ROV company and recently changed to become a JNR Rov Pilot. Best bet is like Carmen says get your CV onto Oil Careers and the likes. If you know someone working offshore with a say as such then that will help alot. John
