flanges leaking during sail-away?
(OP)
We're about to sail away with a converted FPSO, and as part of the pre-start-up checks we need to check a sample of flanges to determine if vessel motion has caused leaks.
Are there flanges that are particularly prone to leaks in terms of type, pressure rating, material, location (length up/down-stream, proximity to bends), fittings, etc?
Thanks,
M

This is possibly because from running on HFO at 140-150degC, shut down involves switching to gas oil at ambient. Not everything cools at the same rate.... so not related to vessel movement.

Our internal piping specifications essentially prohibits the use of 3" and 8" class 150 flanges.
