Oh come on Crab, do you really think two bids on such a complicated tender can be so easily compared like with like? Besides it will be how each of the bidders are going to manage the contract which will determine the quality of the "product".
It is interesting that in todays Press and Journal (NE Scotland) regional paper an oil expert predicts oil at $200/bbl before the end of the decade. Hope the fuel costs have been adequately covered, otherwise today's announcement might be a heavy cross to bear.
