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

Quality Assurance and Customer Service Manager

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
