Production tubing failure on gas lifted well

[ChemEngSquirrel]

I have an offshore platform.

Gas lifted well with lift gas in the 'A' annulus. If the production tubing suddenly & catastrophically fails, the wellhead will be rapidly pressurised to gas lift pressure. The rate of flow across the production choke will be massive with gas lift pressure upstream, way in excess of PSV capacity on the low pressure separator located downstream of the well.

Do I need to consider catastrophic tubing failure?

I suspect it might be a very unlikely scenario but not sure if its normally considered.

Thanks.
