Firstly, you cannot get ROV experience unless you get a job as an ROV Pilot. ROV Companies know and realise this.
They look for people who can FIX the ROV, you learn to operate it on the job.
Many companies use Training Schools to train their people, however that does not mean that you MUST do the Training Schools training to get a job. Some training schools try and equate their training to Diver training. Divers have specific qualifications and training you must have to do the job – there is no such equivalence with ROVs. There is no such thing as an ROV Qualification.
IMCA are a trade organisation made up of offshore companies, they have put together a "standard" that they feel is a minimum, this does not make it compulsory nor "qualified". If you actually look at their standard it is extremely low in my opinion.
In your case I would improve your electrical and hydraulic qualifications and knowledge to add to your IT and telecoms experience.
