comments: Attempted to disconnect tubing bonnet. Adjusted lockring releasing bolts. Worked tension 0-4 ton. Not able to move bonnet. Pressured up tubing bonnet cavity to pump tubing bonnet from below. Continued adjusting releasing bolts and working tension up/down. Tubing bonnet moved up, but slightly skewed. 4-5 mm movement close to the penetrator, 5-7 mm 180 degrees off the penetrator. Continued attempting to release tubing bonnet. Attempted to wiggle assembly horizontally with chain hoists connected to spacer spool at XMT deck. Installed hydraulick jacks to prevent tubing bonnet from dropping back down.
