1. Safety factor for ROV Instruments and ROV/TMS Hydrolics.
Im not going to answer the question but try steer you in a good direction.
Is this the whole question as they asked it?
If so, think about what happens when they are energised or turned on. for instance:
1. If you are adding instruments to a rov do you leave all the power on? probably not….
2. For ROV/TMS hydraulics, it would refer to the procedures for the vehicle as well as the companies precedures. For instance you wouldnt turn on the hydraulics without having someone on comms outside and you would have certain other things in place before operation which would be discussed in TBT etc. But it would depend on what you were doing.
I hope this points you in a good direction. Remember its not just safety for personnel but also the vehicle.
Cheers
