Licensee/Facility: Notification:
Part 21 Database MR Number: H-03-0014
Whiting Corporation Date: 01/31/03
Subject: Part 21 - Initial Notification - Whiting Corporation Cranes
Sold Prior to 1980
Discussion:
VENDOR: Whiting Corporation PT21 No.: 2003-
DATE OF DOCUMENT: 01/29/03 ACCESSION NUMBER:
SOURCE DOCUMENT: FAX REVIEWER: RORP, R. Caldwell
Equipment Identification: The concern is specific to the Whiting No. 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 percent reduction in rated hoist capacity of the effected
cranes will allow for continued use of the cranes without compromising
design safety 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 are requested to contact Whiting Corporation 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.
