My Safety Moment

Hard Hat Required

On my first day at Crystal River, Chris and I were walking down the inspection locations with scaffolding contractors. On top of the boiler I ran into a steel beam and it knocked my hard hat off and smacked my forehead. Lesson learned to carefully plan out walking paths and to take your time.

Responsibilities this Rotation■ Analyzed

– Flow Accelerated Corrosion at Anclote 1 and 2

– Loading on Hanger Support System at Crystal River 4

– Inspection history to predict equipment lifespans

■ Attended– Inspection Services All Regions Staff Meeting

– Hines Mechanical Equipment Reliability Meeting (MERM)

– Asset Configuration Tracker Level II Training

■ Designed– Inspection drawings and submitted piping isometrics through ACT

■ Researched– Structural Integrity HEP Webinar Series

Inspection Drawings Project - Intro

Inspection Drawings Project - Benefits

■ Improving skill set– Applied previous drafting table experience

■ Man hours saved– Help Lead Engineer save time for future

inspections

– Precise drawings will help the drafting team save time during Configuration Changes

■ Dollars saved– Scaffolding and insulation costs are

reduced when you have accurate weld positions

Inspection Drawings Project – Moving Forward

■ Plans to submit these drawings through ACT next fall so they can be uploaded in fusion

Hanger Project - Benefits

■ Learned valuable information– Helped build understanding of the

system prior to using modeling programs

■ Training– Shadowed Steve Grace, Hanger SME,

for walk downs at Crystal River, Hines, and Tiger Bay

■ Testing– Verified hangers are operating safely

Hanger Project - Moving Forward■ Next fall I will be modeling piping systems in AutoPIPE to plot

stresses to optimize inspection locations
