EVENT TEXT
10 CFR 21 NOTIFICATION - WHITING CORPORATION
"This notice is being sent within the two day period to inform you of a safety concern related to Whiting cranes sold to utility companies prior to 1980. The problem was identified through engineering analysis. We are not aware of any failures.
"The concern is specific to the Whiting #25 Hoist Unit (Gear Case). One or possibly two internal support bolts in this assembly may be significantly over-stressed.
"The exact extent of the over-stressed condition can only be determined by individual analysis of each hoist in question; however, based on findings, a 50% reduction in rated hoist capacity of the effected cranes will allow for continued use of the cranes without compromising design satety factors. This limitation should be enforced until the over-stressed bolts have been replaced or analysis shows that an over-stressed condition does not exist.
"Crane owners should contact us at Whiting-Nuclear©WhitingCorp.com and provide the following information; customer name, contact person, email address, telephone number, crane serial number and date of next scheduled outage.
"I trust you find that the notification provided is satisfactory and in compliance with 10 CFR 21 reporting requirements. If you have any questions, please do not hesitate to contact me at fteggelaar@whitingcorp.com.
