Maintenance Management
Planning, types of maintenance, how to organize the department, costs, equipment criticality and life cycle cost (LCC).
Real case
PDVSA, in its Exploration and Production division in the Western zone, ranks all its systems by criticality with a survey of six criteria (failure frequency, operational impact, repair time, repair cost, safety and environment) before deciding how to maintain each one. Sorting the results from highest to lowest gives three zones (high, medium and low) and the maintenance effort is concentrated in the high one.

Equipment criticality analysis
There are not enough resources to improve everything at once. Criticality analysis ranks processes, systems and equipment by their impact (failure frequency times consequence) and singles out a high-criticality zone where it makes sense to start.
How to implement a CMMS: the ANCAP SAP-PM case
ANCAP took 39 weeks and 19,000 person-hours to replace its maintenance system with SAP-PM. Most of that time did not go into configuring screens, but into defining processes and a risk matrix to prioritize work without depending on who asked for it.
Life-cycle cost (LCC)
Life-cycle cost adds up everything an asset costs from the day it is bought until it is retired: acquisition, operation, maintenance and losses from stoppages. It is used to choose equipment and to justify maintenance with numbers.
Maintenance planning and scheduling: how to build the plan
Planning is not the same as scheduling: planning defines what to do and why, scheduling defines who, when and how. The 5 steps, a checklist for building a program from scratch, and the Master Plan that keeps it running over time.
Types of maintenance: corrective, preventive, predictive and proactive
The four maintenance strategies, when each one makes sense depending on how critical the equipment is, and why almost no plant uses just one.
What maintenance really costs: CGM, CIM, CFM and CAM explained
Maintenance cost is not just what the shop spends: it is the sum of intervention, failures and spare parts stock, and the part that is measured least is almost always the one that weighs the most.
