Subject: Over-stress of aux. hoists on Whiting Cranes
Date: March 12, 1997
Pages: 6, Including this cover shoot.
COMMENTS:
Recently, we at Whiting have become aware of a condition of an
over-stressed auxiliary hoist on one of our cranes. Based on this, we
have reviewed a series of cranes and are in the process of sending
notices to affected customers. Attached is a sample letter and a list of
the 11 utility companies that we have notified of this condition. The
authorization of loads up to 40% of rated capacity, as described in this
fax, is a conservative generalization and will be addressed on a case-by-
case basis with each customer. Separate specific instructions by
Engineering or a fax will authorize loads as high as 60% of rated
capacity for a specific application.
The cranes as designed meet the current requirements of AISC, but
violate the requirements of CMAA. We are authorizing operation at a
reduced capacity which will bring operation into conformance with both
requirements. We do not believe this to be reportable under 10 CFR 21,
but we have notified these companies so that they may do further
evaluations.
If further information is required, I can be contacted at (708)
331-4000, extension 4020.
Sincerely,
Mark J. Kwasny

RE: Your Whiting crane(s) serial number(s), 10044.
This is to inform you of a concern related to the continued operation of
crane(s) 10044. This notification is limited, and only customers
receiving this notice are required to take action.
An analysis of the auxiliary hoist on a crane similar to the referenced
crane(s) has revealed some overstressed conditions. These over-stressed
points arc not likely to result in a failure, but are being reported so
that further evaluations and corrections can be made. The main hoist is
not affected by this condition and can continue to be used with out
restriction. As an interim measure we recommend taking the auxiliary
hoist out of service rather then derating because variations in your
design require further evaluation be done before use.
If the above provisions are followed, the crane can continue to be used
without additional concern.
Whiting Corporation, a Delaware Corporation, has no direct responsibility
for the design of equipment sold by Whiting Corporation, an Illinois
Corporation, prior to an asset purchase in 1994. Based on current
information, it does not appear that this condition is reportable under
10 CFR 21. However, we are passing this information on to all affected
utilities for their evaluation.
Until the time repairs can be made, you must either discontinue use or
derate the capacity of the auxiliary hoist to 40% of the original rated
capacity on the referenced cranes.
Whiting Corporation and our sister company Whiting Services Inc. are
willing to assist in repair of these trollies by providing engineering,
repair parts bills of material, and field services
