Module Groupings

As to your last line "Am I right or it may have different meanings?" the answer may be Yes and Yes.

You could be right or it may have a different meaning.

Where did you see this and what was the context of the statement?

Actually I generated a piping layout for one of our client (BAPETCO). The layout was so designed that few of the vessels and pumps were placed on 38' X 7'-6" (container dimensions) structural skids, some vessels were placed on grade upon civil foundation (their piping on ground) and heat exchangers were placed 18' above ground (with their piping on overhead pipe rack). So the whole layout consists of piping that is on skids + piping on ground (offskid). the client asked..

''Please identify outline module groupings and proposed maximum dimensions and weights of modules or similar large equipment''

I think now the situation is clear. please comment. Thanks

In our systems (may be the client too means that)

Modules are single Dispatchable/manufactured assemblies.

The different modules are assembled at site to each other to complete the line.

These are kept as semi-independant so that in case of a fault/repair the corresponding modules are replaced.

The additional reason of making it modular is for handling purpose ( And that is what customer is asking Weight and Dimensions). Eg The LP, IP and HP Turbines could be made together (My example is from a bit other area) but the dimensions and the weight will make it impracticable to even lift it to Turbine bay. So we specify the dimensions, weight, locations, foundation plans etc so that the customer plans for his erection equipments.
