I've been told that Seadrill contracts require their customer to have and provide financial wherewithal to holdharmless, insure, indemnify, etc Seadrill for any environmental issues that start undersea. IMO highly questionable BPC has that capability, BUT if it can farm out ownership AND operatorship of their field to an acceptable (to Seadrill) major O&G E&P player very quickly then perhaps a drilling off the Bahamas could be a go in early 2020 as mentioned by BPC. That's a long shot, IMO
Besides, I seriously doubt West Neptune would do the work. Even though a picture of West Neptune is shown in article's picture, and the article's source was clearly BPC, who said they have an agreement to hold open a slot for using West Neptune in early 2020. West Neptune is simply not available.
If anything happens with an as yet unknown BPC partner, I'd guess Seadrill might be in a position to consider a contract with its higher-spec sister ship West Saturn. It might have time to squeeze in one or two wells, but my belief is that it would be very tight scheduling to pull off, if even at all. T.D.
