'What could possibly go wrong...'
Oddly, and I share your surprise, not a lot. These aren't logistics in the sense of RFA's refuelling ships at sea etc. basically they're used to transport personnel out to ships to save coming alongside, maintain bouys, act as vessels of interest to pick out of normal shipping etc. They took over from the Royal Maritime Auxiliary Service in 2008 and so far appear to not have f***ed things up completely.
