I appreciate that divers work in the water and therefore may have an idea of the tasks being performed. Back in the early days of the industry, divers used to go from diving to ROVs.
These days, ROVs are much, much more technical, much more fibre optics, networks and hubs, electronics. Generally people are employed for their technical ability – to maintain and fix the equipment – you learn to operate the equipment afterwards.
Right now, even the most experienced ROV personnel are being laid off by most of the major companies, there is a very large downturn in the industry which looks like it may last for some time.
There are many discussions regarding the pros and cons on doing any ROV training course, please read through the Rookie section.
