    In recent years, modular engineering and construction has been a subject of increasing interest throughout the process industry. This interest has stemmed from a growing concern over the high costs and protracted schedules encountered in new plant construction, particularly in developing areas ;vhere adverse site conditions and limited skilled labor have accentuated the problem.

    AS applied to chemical and petrochemical plants, modular engineering and construction has come to mean a prefabricated and packaged plan't assembly or subassembly that is to be transported and installed at a l-emote operating site.

Most of the emphasis to date has been placed on the various aspects of pack- aging and trznsport, Very little attention has been given to improving the contents of the transport package.

    Most importantly, the savings are obtained without sacnifi~ing plant operability or changing the process in any way. Under MPECS, an appreciable
portion of the process plant material and labor is eliminated. Also, an !appreciabl~portion of the field work can be transferred to the controlled, high-productivity environment of fabrication shops.
