This subject has been done to death in the past (in my opinion) but I just heard that one of the major players has advised its’ trainees and P/T 3s to look for other work as they cannot guarantee them all employment in the foreseeable future.
A course was a possible bonus on a technical CV but the offshore industry is closing down rapidly as a reaction to the oil price. Now is not a good time to be trying to get into ROV as a trainee.
Basically the oil companies are not going to go to the expense of dragging something out of the ground to sell at 40-something $/ barrel if they can leave it there for a couple of years and get well over 100-something $/ barrel.
This might seem like I’m stating the obvious but it’s something that I never even considered a factor until I was in the game.
Save your money, get some qualifications if necessary and wait for the next boom in a couple of years time. It will come and there will be many trainee openings, but the oil price is, unfortunately, God.
