MAINTENANCE OF PLANT OPERATIONS (MOPO)

Instructions and Forms

Definition and Purpose

Maintenance of Plant Operations (MOPO) is a detailed document submitted by the Contractor to request process shutdown(s), utility tie-in(s), work in areas that may risk unanticipated outages, or flow diversions to accommodate site construction activities during a project. Such activities may include (but are not limited to) new tie-ins to utilities or structures, mechanical modifications to process piping or equipment, demolition, bulkhead installation, and cleaning processes.

The MOPO provides a detailed plan to the Owner and Engineer that describes specific aspects of the work, including purpose, time of execution, and anticipated impacts on treatment processes. The MOPO also includes contingency measures and provisions for rapid closure in the event that shutdown or work progress difficulties are encountered. Information from relevant trades associated with the requested shutdown, diversion, or tie-in is also included.

The Owner should use the information within the MOPO to define operational procedures and methods to safely and successfully assist the Contractor.
