What happened in P&A:
Disintegrated control line clamps and loose control lines increased the required overpull to be able to pull the completion.

What Was Planned

Pulling completion string without any overpull issues.

What Was Learned

From Ronald Medina: “The connection on the tubing is: 5 ½” 23# 13Cr L80 Tenaris Blue Dopeless. This has a “body” tensile strength of 240 MT, but the “coupling load face” is only 134 MT. This 134 MT is applicable if using the standard inserts in the Elevator.”

What Actions Are Required

Offshore were informed by this reduction of available overpull.
