Icefield Snubber Adjustment

Migrated to http://confluence.ship.iodp.tamu.edu:8090/x/VgJmB with complete SOP for using jig (both for Icefield and Flex-IT).

will delete soon?

The end piece for the pressure case has multiple parts: an External Key (external to the pressure case), End Seal (cap), Snubber (shock absorber), and Internal Key (resides inside the pressure case). The Internal Key fits into a T-Slot keyhole in the orientation tool and the External Key fits into a Muleshoe keyhole on the Sinker Bars. The end piece is referred to as the Keyed End-Seal Snubber (KESS).

Check the orientation of the Internal Key. If it needs adjusted, loosen the jam nut and orient the key to its proper location. Check the alignment with a straight edge. When satisfied, tighten the nut without allowing the key to rotate. This is best handled with two people. Check and recheck the alignment after tightening. In general, once the key is locked into place, it will rarely need to be adjusted. The Flexit tools has a jam nut and an additional pin that holds the key into place while allowing the key to move in and out around an internal snubber.
