Hello Shabeer,

You should read and understand more about Hogging and Sagging before doing the analysis.

Hogging and Sagging is normally taken into consideration, when a piping system is situated in more than one FRAME, MODULE or BAY as you may call it.

FPSO are built in sections called FRAME, MODULE or BAY. Each FRAME, MODULE or BAY moves when subjected to loadings. These movements are calculated by NAVAL ARCHITECTS.

In turn, these movements are incorporated into CAESAR II model as Displacements.
