EMERGENCY MAINTENANCE

• "FIX IT WHEN IT IS BROKEN"
• Individual orders-requests are issued upon a malfunction of the technical system,
• Predominantly "FAILURES - OPERATION STANDSTILLS" - production losses,
• High maintenance costs. Large stocks of spare parts and almost always a lack of parts,
• Inability to control the maintenance process and maintenance costs planning,
• The following activity is not planned, "excuses" and searching for the culprit dominate (I do not have any repair staff available, the acquisition has been delayed, You have contacted us too late, ...)
• No proper communication between the ordering party and the contractor (communication via orders only) (poor handling of means – bad repair),
• Everything is "urgent" or there is "no work" and the overtime is predominant (inability to monitor and meet the deadlines)
• Maintainers are heroes or culprits (they completed the repair and it "is working")
• Maintainers are a "FIRE BRIGADE", they only resolve problems
• Maintenance strategy currently predominant in NIS

PREVENTIVE MAINTENANCE

• "FIX IT BEFORE IT IS BROKEN"
• Annual maintenance orders (maintenance activities and costs are planned and shown on an annual basis),
• The maintainer`s main task is to prevent system failures – standstills,
• The operation of the technical system is under the maintainer`s care as well,
• Lower maintenance costs, a smaller set of spare parts easier for planning,
• Proper two-way communication between the ordering party and the maintainer about the operation of the technical system,
• Overhauls of technical systems are jointly planned,
• Disciplined execution of planned preventive maintenance tasks is predominant,
• Few organisations have implemented this maintenance strategy in their processes (Downhole Pumping Equipment Section has been using this type of well equipment maintenance for years)

PROACTIVE MAINTENANCE

• "MONITOR THE SITUATION AND ANALYSE"
• Orders for several years and specialised maintenance teams,
• Contractually defined liabilities and risk,
• Mutual interest in the proper functionality of equipment,
• Cooperation between the user and the maintainer brings an added value,
• Eliminating - foreseeing a failure,
• Optimisation of the technical system and the maintenance system,
• Efficient operation of the technical system and its cost-effectiveness.
• The lowest maintenance costs
• Elements of this maintenance strategy have been introduced in NIS - well equipment maintenance process (database, vibro-diagnostics of the condition of bearings, monitoring the quality of oil, thermovision)
