Summary of Damage Record Forms for Hydroelectric Runner/Discharge Ring/Stay Vane Assessment
This document is a template package containing standardized forms for documenting damage assessment records on hydroelectric turbine components, specifically runners, discharge rings, and stay vanes. The forms are designed to be used by government assessors to track and maintain comprehensive damage records following inspections of federal hydroelectric units.
Form B-1 serves as a cover sheet summary for runner damage records, organizing damage by blade pair (1-2 through 13-1) and tracking the number of damage record sheets and damage areas per blade pair, with unit totals required. Form B-2 is the detailed runner damage record form, which includes a blade pair sketch, damage area dimensions in inches (length x width x depth), defect classification (cavitation, corrosion, crack, or other), priority designation by government (high or low), defect group number assignments, and repair completion and inspection dates. Forms B-3 and B-4 follow the same structure for discharge ring damage, organized by zone below blade pair rather than individual blade pairs. Forms B-5 and B-6 document stay vane damage (identified as G19-G21 and G22-G24 vanes with up to 31 individual stay vanes trackable), with assessment types categorized as Initial Assessment by Government, Secondary Assessment, or Other. All forms require unit number, date, submitter identification, and photographic or graphical documentation of damage areas for reference and tracking purposes.
