Riser Guard welded to Conductor/ pile 1

[fremgym]

Hi,

As per subject, can we weld riser guard to conductor/pile? If it can be welded to conductor/ pile, is there any example/ platform which adopt this?

*Platform is fixed structure type and it is supported by conductor which also act as piles.

The attached is jacket vertical framing. The location of riser guard to be welded onto conductor is as per mark up in the drawing.

[tt]I would be extremely wary of welding directly onto a conductor that is also acting as a pile.

The weld class from a fatigue standpoint is likely to be very poor and you run a risk of any crack which initiates in the weld migrating to the main body of the conductor pipe with catastrophic consequences.

It would probably be safer to have a riser guard clamped onto the conductor rather than welded. This will also be easier and quicker to install than a welded solution.[/tt]
