Appendix C: Merged Failure Data
C-1. Description
It is necessary to acquire mechanical and electrical equipment failure data specific to navigation lock and
dam equipment to better represent the reliability models. Accumulated data will be analyzed to determine
the failure rates that are experienced for applicable mechanical and electrical equipment.
C-2. Equipment Failure Survey
An equipment failure survey Internet Web site was developed as the means to acquire the necessary
mechanical and electrical equipment failure data from across the United States. The survey format is
currently located on the Internet. The survey Web site homepage is shown in Figure C-1. The survey
web page is included in Figure C-2. Survey access may be obtained by logging in and creating an
account. The user must create a password when creating the account, and then once the account has been
created, the user may log in any time. For each subsequent login, repetitive information will
automatically reload, and the user need only input the failure data itself.
