How do you calculate hook load capacity in a derrick?
Static Hook Load: The static hook load is the maximum weight in static conditions (not tripping) that the derrick/mast and the substructure can withstand. For instance in a stuck pipe situation, if a derrick is able to pull up to 1,000 Klb before failure, then its SHL will be 1,000 Klb (not considering safety margins). This value has nothing to do with the power of the rig, which is determined by the power of the drawwork. To calculate the static load that the derrick/mast and the substructure will withstand, it is needed to find the heaviest load in AIR, and it can be either casing or drilling string, in most cases it will be the casing string, unless small holes are being drilled. SHL = (HAS + TB + MO) * 1.25 SHL…Static Hook Load (lb) HAS…Heaviest String in Air (lb) TB…Traveling Block (lb) MO…Margin of Overpull (lb)
