Guyed Flare Design -Y direction Force

[prashious]

Can anyone suggest the reason for a -Y direction force witnessed in case of a Guyed Flare design?

You are not giving enough information. However, the only "-Y" force you should have is the dead weight of the stack itself.

When the vessel deflects, the guy wire will restraint the vessel. Depending upon the stiffness of the wire (& the vessel) the vessel will see reaction of the wire.

This reaction can be broken down in to 2 components, one acting down on the vessel and one horizontal (in the direction of the wire attachment).

Hi Mandeep1,
Don't understand your answer?
Where is the vessel in this problem?
We are talking about a Flare Tip which is sitting on a vertical structure which is supported / tied back (guyed) to grade with wires.

Is the Flare & Flare Tip on what location: FPSO, LNG FPSO, TOPSIDE PLATFORM?

Don't ask me.
BTW - I have not to date seen a guyed flare on an FPSO, LNG FPSO, TOPSIDE PLATFORM

Hello folks

The problem is complex with a high degree of indeterminacy because of the elastic nature of the vessel components and guys. Mandeep pointed out one of the problems in that tension of the non-redundant guy imposes a vertical compressive force on the vessel.

However, I have seen this type of system analysed using piping analysis software. Several programmes are commercially available which (with a little creativity) can do this
