From my (much younger) days working as a roughneck, if you're "drilling" only through water, and have a crack crew with good reinforcements to spell them off when they get tired, 4 minutes per section might just be possible if everything goes perfectly.

No crew I worked on ever got close to that, thank goodness, since we were drilling hard stuff, so we roughnecks got lots of chances to sneak off to the boiler hut to try to catch up on our sleep during those night shifts... LOL

How about 90' sections

Block One appears to be the shallower area, with water depths of 1500 meters or about 4,200 feet.

4,200 feet divided by 90ft sections = about 47 sections, lets round up to 50 sections to make the math easy, even for me.

5 hours = 10 sections per hour or one every 6 minutes if the 5 hour figure is accurate.
