You'll note that in addition to the certificate you need 12 months relevant experience - that might be challenging for a noobie!
Whether anyone will hand over a hire rib to you with that level of qualification and experience for this type of work might be a different question.
i can hire a RIB for this task which is quicker, cheaper and usable on my own if possible.
A properly constructed risk assessment might find it difficult to rationalise an inexperienced skipper working on a small boat performing any task simultaneously to helming the boat with major shipping around. Would you survey a motorway by driving along the hard shoulder whilst looking at the verge?
Shiny has a point about the choice of craft. I'm not sure what the survey work involves, but if you need to get "on and off" then that is going to need careful thought. If there are speed limits you will not really want a deep V hull (or will waste a lot of fuel pushing water around). I'm not a fan of prop guards - but you will presumably be working close to the bank out the way of the big ships and at risk of damaging the prop on submerged objects; shorter shaft engine or even a jet might be worth thinking about.
I don't want to suggest that driving a boat is rocket science, but using one safely, and efficiently in the course of your employment isn't quite as trivial as perhaps it first appears.
