Thanks for your reply Ray.
I had thought it was deemed to okay to be fairly proficient in one or more departments ie. Mech/Hydraulic or Electronic. as it was a team I suppose i thought you would have an ET specialist as well as Mech/Hyd ? ! anyway I still enjoy learning at the ripe age of 45 so might just do an electronic course as preparation. good advice. cheers.
Actually on that note any advice welcome regarding decent reading material/links useful for for ROV maintenance/repair.
Thanks again to all who have replied. 🙂
