I don’t know anyone who can say hand on heart that it’s an enjoyable job. Too many uncertainties, variables & the amount of work can fluctuate in the extreme.
Getting your foot on the ladder could be difficult. You’ll need contacts on the inside. Use any means at your disposal to get yourself on a DSV. IE take any job available. Rigger, sat tender, project admin. Anything that will get you offshore. Don’t rely on offshore HR giving you a job. If you’re in ABZ keep an eye open for DSV’s in the harbour. Take a copy of your CV containing all your relevant experience & ask at the vessels security hut if you can speak to the OCM (offshore construction manager) He’ll put you in the picture & will more than likely admire your pluck at getting OB “his” vessel.
Good luck & don’t let yourself be put off. If I can offer any other help feel free to ask.
