The difficulty for you Mido is that I sense are two trains of thought about whether attending an ROV training course is worth it or not.
Most people that have been working offshore for some time have very little time for training schools as often, they may appear to be selling a product by devious means employing the usual phrases like:
Exciting job, international travel, earn big bucks, meet interesting people etc etc.
All your job and money worries are over is just about what they are touting.
Overall the dream ends up shattered and that’s why some experienced hands are critical of the system.
As this thread isn’t about the merits of attending a training school or not I will start another thread on just that topic.
