Lifting analysis of a modularized steel structure

This thesis aims to design the lifting lugs required for the lifting operations that are propaedeutic for the land & sea transport and the installation on-site of the modules. In the last case, the tolerances are strictly limited because some pipes and equipment are already positioned on the modules and they have to match the layout of the pipes and equipment coming from the modules around. It is important that the lifting operations will be performed properly and will guarantee both the global integrity of the modules and a high precision in the installation phase. These requirements lead to a very rigid structure able to carry important loads (mainly operational) and able to maintain its shape during the lifting. It is now clear how important are the lifting operations and how much they influence the design of the main pipe rack.
