STR are one of those agencies that do not specialise purely in offshore employment but they can come up with some little gems from time to time.
Not really known in the game too much, but pop over to their site and add the key word ROV into the search box. It only takes a couple of seconds to do, but pulls up some interesting results.

God luck!
