An apparatus for monitoring a plurality of operations, particularly on an offshore drilling rig, comprises a portable housing, a plurality of dedicated monitoring units associated with the housing, and a master microcomputer unit associated with the housing for handling information transfers between each of the dedicated monitoring units. Each monitoring unit includes a dedicated central processing unit which controls the operation of that unit. Control is maintained over a number of transducers which detect various physical conditions associated with the monitored operation. The electrical signals obtained from monitoring the conditions are processed and displayed on respective display consoles located in the housing. Intercommunication among the various units is achieved through serial input/output devices establishing communication channels between each unit and the master microcomputer unit.
