OFFSHORE STEEL CONNECTIONS

[Aumar]

I am working on a project that require adding some pipe supports for 2" and 4" pipes to an existing offshore facility(Platform). we designed 100% welded connections (both shop welds and field welds). The client is asking for an alternative connection system, so as to avoid or optimise shutdown.

I thought of beam clamps and/or hangers and bolted connetions. I cant find a code that gives exceptions to 'no bolted connections offshore'.

I would like some ideas pls. thanks.

Are v-clamps and flanges permitted?
