Cairn Half Yearly highlights, page-110

I found the part below rather interesting. To me this reads as though existing capex figures are 'assuming' that they have to hire a FPSO. WPL have their own FPSO's so this would significantly reduce capex.

The only thing I am not happy about is the time to producing oil. 2021-2023!!! it's 2016! that's potentially 7 years away. I just think it's ridiculous and I really hope Woodside come on board, takeover Operatorship and fast track the hell out of this field. I am sick of CNE.

But based on the improved contracting environment today, but also importantly our experience of drilling five wells into the reservoir so far, we are updating today that guidance with reductions of 25%, 30%, so we see sub-$15 a barrel all-in development CapEx for a field of the 2C size that we have guided to.
This assumes a leased FPSO development, so you can see the bulk of the CapEx there is really in development drilling and subsea installation. Operating costs associated with that development scenario, $8-10 a barrel, and that includes an FPSO leased cost assumption in there
