Having elaborated that not all Plant items are suitable for Modularisation for Onshore Facilities, 3 examples follow with the purpose of illustrating what may prove benificial to Modularise
In Section 5 b, Process Modules Onshore an understanding of the variance of meaning of the term "Process". There then follows examples and the first illustrates the large one piece propcess module, the other examples show how in a different way a building block approach is often used.
In Section 5 c, Boiler Modules Onshore it further continues the concept of the large single module with supporting assemblies as sub modules.
In Section 5 d, Power Generation, Drilling Modules Onshore other elements of module creation. Large generators in themselves are a sustanial item forming their own Module. By comparision Drilling Rigs onshore have historicly been treated as small component modules to be built into a larger spread. In part this is due to the historical nature of Onshore Drilling where transport small to an underdeveloped location, set up, drill, knock down and progress on to a new location. In a similar manner as the rig, tanks, mud pumps, chemical preperation, shale shakers etc may be modules suitable for road transport and grouped to provide the total capacity required. (The Offshore opportunity of transporting a large rig module on Semi Sub or FDU is rarely available as an option Onshore.)
Section 5 Modules Onshore been used to demonstrate that not all items, particularly large and heavy are suitable for Modularisation. Where the module is a marine lift in to shore, once onshore complications may occur where the module may have to pass under a bridge or where power lines occur, or marshland roads exist etc. In such situations another approach for columns is that the column itself is dressed with instrumentation platforms and pipework . Often delivered in the horizontal mode it is raised at site into the vertical with cranes and the base tailed in by another crane or fed on a temporary tilting base which is removed just prior to lifting into its final place. The first 3 pictures are of long slender vessel which in the vertical would obviously be a complication if in that position in a module. The last vessel is somewhat shorter but shows how pipework can be incorporated so that as the vessel is installed it could be hooked in to an adjacent module.
