LINDA SMITH R4 21.21 UNSPECIFIED PARAGRAPH VERN HODGE NRR OVERSTRESS CONDITION ON SINGLE FAILURE PROOF CRANE TROLLEYS "On January 5, 2005 as a part of a crane re-rate analyses and study Whiting Corporation identified an overstress condition on some hoist equalizer plates and welds. This condition is limited to the hoists of some redundant (single failure proof) cranes.
"Whiting Corporation has performed a preliminary review and have isolated the problem to the family of redundant trolleys also known as single failure proof trolleys. No other types of cranes are affected. It has not been established at this time which specific redundant trolleys are impacted. This assessment will require a cases by case review.
'Whiting Corporation have or are attempting to contact these customers directly to notify them of this circumstance. These are the only potentially impacted customers.
"The hoist units identified above, are to be inspected as follows and then limited to 50% of rated capacity until such time as the units can be evaluated and/or upgraded. The following specific serial numbers can be operated at 100 Tons (SN 10403, 10388, 10389, 10510). SN 10698 is currently being evaluated and is limited in capacity by other factors being addressed with the customer. The area to visually inspect, for cracks in the plates or welds, is the assembly, adjacent to the rope termination, at each end of the equalizer arm, that the nut on the rope fitting bears against. Suspicious visual indications of potential cracks can be further examined by Magnetic Particle testing if warranted. A lack of any visible cracks during visual examination will allow the unit to be placed in operation at the 50% reduced capacity. Please note no reports of field failures or cracks have been reported as of the issuance of this notice.
