What happened in Surface section:
Overpull experienced trying to pull the WHRT clear of the Housing after release.

What Was Planned

To run the 18 3/4″ RT with blind plugs.

What Was Learned

Evalaute to use BAll valves instead of blind plugs. Ball Valves on the Running Tools would allow the Pressure Inside the Conductor / Casing to be equalised thus taking away any chance of pulling a Vacuum.

What Actions Are Required

Change the blind plugs for ball valves on the WHRT.
