Figure F13. Photographs of pulling tool before and after deployment. A pulling tool is required to remove the logger in an original-style CORK. One was removed from Hole 1200C in 2009 using the ROV Hyper Dolphin. Once the pulling tool was in place, the valve was activated, releasing the logger. (In this case the logger was actually a steel tube inserted to seal the hole.) A line was attached to the pulling tool from the bottom of the ROV to pull the logger out of the hole. The ROV was recovered, followed by the pulling tool and logger.
