Floating Roof Reliability TR Brainstorming
Goal is to provide a scope covering internal and external floating roofs. Some ideas:
1. Definitions/Standardization of terminology
2. Additional design guidance not found in 650 Annex C/H
a. Design selection guidance (advantages/disadvantages)
b. Operational and environmental considerations
c. Design life/longevity/fatigue considerations
d. Materials selection
e. Avoiding conflicts (crashing into the roof/floor/shell attachments/columns/etc)
f. Accommodating robotic inspections
3. Erection
a. Welding
b. Fasteners
c. Construction tolerances
4. Coatings
5. Construction/Repair testing
6. Recommended tasks/checklist for internal/external/periodic/environmental inspections
7. Operational guidance
a. Landing (low level alarms, heights, critical zone etc)
b. Floating
c. Monitoring
d. Warning signs
8. Repairs/Maintenance
a. In-service
b. Out-of-service
9. Safety (primarily focused on out of service considerations since 2026 covers in-service)
10. Seal guidance/Vapor controls
a. Primary
b. Secondary
c. Penetrations
d. Venting/Vapor Recovery
11. Guidance on auxiliary equipment
a. Roof drains
b. Gauging
c. Venting
d. Sampling
e. Skimmers
f. Foam systems
g. Mixers
12. Guidance on environmental conditions for EFRs

b. Snow
c. Freezing
d. Seismic
13. Troubleshooting/Recovery Guidance
a. Leaks
b. Damage
c. Sinking
