Spartacus-1
I have no idea really. Since it is a dynamic positioning rig there would be no anchors to lay. So I reckon they could start straight away. The time in Accra is 6.16Am at the moment so they have all day ahead of them. By the time we wake up in the morniong they could have spudded the well.
