aky_777,
With the class 4 Im also presuming you got your HND in Marine Engineering and NVQ Level 3 in Merchant Vessel Engineering?!
I would’nt of thought there would be any need to pay through the nose for any of these courses as by studying these and with 4 years experience offshore I’d say you’re more than qualified…..more so than most the trainees they send out now!
My company paid for my ROV course a few years ago and to be honest it was a waste of time, I learned more in my first few trips as trainee P/T. The mechanics/hydraulics was’nt a problem but like your self we used to have dedicated ETO’s so I had’nt really done much in the way of electrics since my HND but once you get those drawings out the old electrical theory comes flooding back.
It didnt take me long for promotion either, just keep your head down, nose clean and get stuck into the competencies.
I would just get your CV out to the big players and see what they come back with, if they want you to do the course that much Im sure they’ll pay for it.
Good luck.
