Borgland Dolphin


What happened in Top hole:
To be able to use it for BHA-handling, a hole was made in the protector.

What Was Planned

When checking spare thread protectors prior to laying out BHA components, it was found they were sent out without pre-made holes for the extender to go through.

What Was Learned

Remember to check that the thread protectors are sent out with pre-made holes.

What Actions Are Required

The thread protectors must have pre-made holes for FG and H90 connections. This makes the operation quicker and safer compared to doing it on the rig. Also reported in the Schlumberger internal reporting system.
