Dans le monde à enjeux élevés du pétrole et du gaz, les temps d'arrêt ne sont pas une option. Une panne d'équipement peut entraîner des réparations coûteuses, des retards de production, des risques pour la sécurité et des dommages environnementaux. C'est là que la **maintenance préventive (MP)** joue un rôle crucial.
**La maintenance préventive** est une approche proactive de la maintenance, axée sur **l'inspection systématique, la détection et la prévention des défaillances naissantes** avant qu'elles ne surviennent. Elle implique un programme planifié d'inspections, de lubrification, de nettoyage, de réglages et de remplacements conçus pour maintenir l'équipement en parfait état de fonctionnement.

Dans l'environnement exigeant du pétrole et du gaz, la maintenance préventive n'est pas un luxe, mais une nécessité. En mettant en œuvre un programme de MP solide, les entreprises peuvent minimiser les temps d'arrêt, augmenter la sécurité, prolonger la durée de vie de l'équipement, optimiser la production et, en fin de compte, réaliser des économies à long terme. Une approche proactive de la maintenance est essentielle pour garantir le fonctionnement fluide et fiable des actifs pétroliers et gaziers.
Instructions: Choose the best answer for each question.
1. What is the primary goal of preventive maintenance (PM)? a) To fix equipment breakdowns as quickly as possible. b) To minimize downtime and extend equipment life. c) To reduce the number of employees required for maintenance. d) To eliminate all potential equipment failures.
The correct answer is **b) To minimize downtime and extend equipment life.**
2. Which of the following is NOT a benefit of PM in the oil and gas industry? a) Increased production efficiency. b) Reduced safety hazards. c) Lower overall maintenance costs. d) Increased demand for oil and gas products.
The correct answer is **d) Increased demand for oil and gas products.**
3. What type of PM uses sensors and data to trigger maintenance only when necessary? a) Scheduled maintenance. b) Condition-based maintenance. c) Predictive maintenance. d) Corrective maintenance.
The correct answer is **b) Condition-based maintenance.**
4. Which of the following is a crucial step in implementing a successful PM program? a) Hiring the least expensive maintenance technicians. b) Keeping minimal records of maintenance tasks. c) Developing a comprehensive maintenance schedule. d) Focusing solely on cost reduction without considering safety.
The correct answer is **c) Developing a comprehensive maintenance schedule.**
5. Why is PM considered a necessity in the oil and gas industry? a) Because it helps reduce the environmental impact of oil and gas operations. b) Because it is required by law in all oil and gas producing countries. c) Because downtime in oil and gas production can lead to significant financial losses and safety risks. d) Because it allows companies to maximize profits by increasing production output.
The correct answer is **c) Because downtime in oil and gas production can lead to significant financial losses and safety risks.**
Scenario:
You are the maintenance supervisor at an oil and gas production facility. You are tasked with developing a PM program for a critical piece of equipment: a high-pressure pump used for extracting oil from a well.
Task:
**Potential Failure Points:** 1. **Bearing Wear:** Excessive wear on bearings can lead to noise, vibration, and eventual failure. 2. **Seal Leakage:** Leakage around the pump shaft can result in fluid loss, contamination, and damage to surrounding equipment. 3. **Motor Overheating:** Excessive motor temperature can damage the windings and lead to motor failure. 4. **Pump Casing Corrosion:** Corrosion of the pump casing can weaken the structure and lead to leaks or catastrophic failure. 5. **Pipework Connections:** Loose or damaged connections in the pipework leading to and from the pump can cause leaks and pressure surges. **PM Tasks:** 1. **Bearing Inspection:** Visually inspect bearings for wear, damage, and excessive noise. Replace bearings if necessary. 2. **Seal Inspection and Lubrication:** Inspect seals for leaks and damage. Lubricate seals as per manufacturer recommendations. 3. **Motor Temperature Monitoring:** Monitor motor temperature using a thermometer or thermal sensor. Check for overheating and adjust motor cooling system if necessary. 4. **Pump Casing Inspection:** Visually inspect the pump casing for signs of corrosion, damage, or leaks. 5. **Pipework Connection Inspection:** Visually inspect all pipework connections for tightness, damage, and leaks. Tighten any loose connections and repair any damaged sections. **Intervals:** 1. **Bearing Inspection:** Monthly. 2. **Seal Inspection and Lubrication:** Weekly. 3. **Motor Temperature Monitoring:** Daily (during operation). 4. **Pump Casing Inspection:** Quarterly. 5. **Pipework Connection Inspection:** Monthly. **Simple Maintenance Schedule:** | Task | Interval | Responsible Personnel | |---|---|---| | Bearing Inspection | Monthly | Maintenance Technician | | Seal Inspection and Lubrication | Weekly | Maintenance Technician | | Motor Temperature Monitoring | Daily (during operation) | Operator | | Pump Casing Inspection | Quarterly | Maintenance Supervisor | | Pipework Connection Inspection | Monthly | Maintenance Technician |
