That's not quite correct. In its pending motion for partial summary judgment against BP, RIG acknowledges that under the drilling contract, RIG must indemnify BP for BP's liability to any RIG employees who were injured or killed. The contract also requires RIG to bear the expense of the loss of its drilling platform (meaning it can't sue BP for that loss, regardless of whether BP caused it). But other than that, RIG says the drilling contract requires BP to defend and indemnify RIG against any other liabilities -- for example, to non-RIG personnel on the platform, or other victims of the spill, or fines, penalties, etc. At least in the context of RIG's insurance, Judge Barbier seems to agree with RIG's interpretation of the contract.
