Lessons Learned - Orbiter Vehicle (OV) Hydrogen (H2) Tank Removal
Year: 1992
Abstract: Description of Driving Event:
During removal of the H2 tank from the OV-104 mid-body, a crane was used to take up the initial cable slack and transfer the load from the tank struts to the GSE lifting fixture. The move director called for a crane movement of "up at 1 in/sec" and the crane controller relayed the command to the crane operator. The actual lift rate was on the order of "up at 3 in/sec" and a momentary vertical load of 800 lbs was applied to the tank assembly. This load was immediately reduced and the tank bolts removed. The normal transfer load is made up of a 150 lb tank lifting fixture and a 235 lb tank weight.
