Saddle Calculation for Launcher & Receiver

[AnEngineer]

I have horizontal launcher-receiver designed to B31.8, saddle mounted and bolted on skid.
Not sure what calculation shall be provided by the trap manufaturer for the saddle. Can not find any reference to saddle calculation in B31.8.

Is Zick Analysis (for pressure vessel) acceptable even though the launcher-receiver are designed to B31.8.

Or is there other calcualtion that needs to be performed.

Help will be appreciated.

I would think the same calculations as for a vessel skirt. That is, weight, siesmic and wind loads.
