The on-site construction time and shortening of the overall constructionschedule is achieved by having completemodules manufactured off-site in specialised facilities.  With manufacturing taking place in off-site facilitiesan added benefit is that weather related delays on-site are also avoided

Is achieved by a much clearerscope of supply which in turn makes the supplier responsible for managingcost overruns.  Reduced manufacturing and assembly time is required, the use ofstandard and readily available materials help reduce costs.  Handlingand logistical costs are also reduced because is a single component thatrequires transport instead of many individual components

Manufacturingin a single company/location ensuresconsistency, simplification of procedures and a specialist’s attention to quality. Fabricatingthe process system indoors means that there are virtually perfect conditionswhen completing all welding and other quality demanding tasks and by a highly skilled workforce

A modularskid comprises of an integrated structure with which to mount and assemble thewhole process system together as a single complete unit. This results in an efficient and simple to handle andtransport system. A modular skid can also be chosen to replace part of asystem that is obsolete. This ultimately results in less time being spent withworkarounds

Thereexists a large part of the market for skids/modules that are reusable infunction moving from site to site.  Thisfacilitates the need for design andfabrication of a series of units requiring batch purchasing and standardisationof drawings and components
