Static Hanging Lines
Routing
Check the routing of the static cable to ensure that it hangs freely without excessive contact with structural components of the mast. Pay particular attention to areas around the girts and racking board where the cable can become trapped.
Check the length of the cable to ensure it has not been smashed by pipe or traveling equipment. Block hanging lines should be tied back out of the way and if the shackle is left attached it should be properly secured to prevent dropped objects.
Temporary installations of top drive drilling units may exceed the load rating on the block hanging line and/or the hanger on top of the traveling block.
Top drive drilling units, rotary hose and service loop clamps, and stabbing boards, can all be damaged by, or cause damage to, static hanging lines.
End Connections
Inspect thimbles and mechanical sleeve fittings for bending or deformities. Check for broken wires in and around factory installed mechanical sleeve fittings. When wire rope clips are used on static lines, the load rating of the cable may need to be reduced. Poured socket fittings done with Thermoset resin should be checked for cracks and broken resin in the fitting.
