I wonder who they will rent an aircraft carrier from, when they need one? To bad, that was a decent ship. I somehow doubt she is fully servicable or the bidding would only include international bidders, that are qualified. At this stage in the world's economic downturn, there won't be many bidders.
Those ships are utilitarian as far as living standards go and would require an extremely expensive refit. Even for an extravagent oil magnate, it would be cheaper and easier to build from scratch.
I am also willing to bet, spares are a nightmare and special purpose built. Again extremely expensive. There must be several million pounds($) of scrap in her though. Her generators alone, would provide enoung power to run a small city.
