How did you manage to just complete an ROV training course and gain a PT2 grading at the same time?
If you manage, by an incredibly slim chance, to land a job as a PT2, you will be totally out of your depth and a danger/menace to everyone on the system, with little chance of making it in the industry as you will soil your reputation before starting it. Your name would get the post nominal title NRB (Not Required Back) behind it.
Anyone that has just completed an ROV training course emerges as a Trainee Pilot/Tech, no matter what technical qualifications the person has. It is still a steep learning curve to PT2 for a trainee.
Did the training school tell you that you are now a PT2? Without a single offshore entry in your IMCA approved ROV log book?
Try looking for an ROV Trainee job and the best of luck to you.
