I sincerely hope you are correct with your assumption that extra cash would be made available, but from my experience with some major oil majors it would come (perhaps) with much hand wringing.
In the past I have fought long and hard for changes that were required when JAROPS3 came into being only to be told that they were not covered by their regs so they could not follow ours. It took a number of visits from the Authorities to convince them to change or have their decks closed.
I have to say this was not the UK, but in Europe but they were same companies operating in the UK sector.
I have other examples of requirements that were ignored on cost grounds so I need to be convinced that the large sums required will be provided.
