I am concerned about whether to use Epoxy CS and GRP as per for 68" Seawater line.
And Civil also is worried that if we use GRP, due to water in the UG, the UG GRP piping might be floated in the water.
So, I would like to ask the check of Buoyancy effect by CAESAR II for in cases of Epoxy CS and GRP respectively.

can anyone guide how to apply or check buoyancy effect in cII
