Dans l’industrie pétrolière et gazière, où la sécurité et l’efficacité sont primordiales, la moyenne des processus (MP) est une métrique cruciale pour mesurer et contrôler la qualité des produits. Elle représente le nombre moyen de défauts ou d’unités défectueuses pour cent unités de produit soumises par un fournisseur pour une inspection initiale.
Voici une décomposition de la MP :
MP = (Nombre d’unités défectueuses / Nombre total d’unités inspectées) x 100
Exemple : Un fournisseur soumet 1 000 unités d’un composant spécifique. Lors de l’inspection, 15 unités sont jugées défectueuses. La MP serait :
MP = (15/1000) x 100 = 1,5 %
Cela indique que 1,5 % des unités fournies étaient défectueuses.
La MP en action :
Conclusion :
La moyenne des processus est un outil puissant pour maintenir des normes de qualité élevées dans l’industrie pétrolière et gazière. En suivant et en gérant efficacement la MP, les entreprises peuvent atténuer les risques, améliorer l’efficacité et garantir le bon fonctionnement des infrastructures critiques. Cette métrique souligne l’importance de partenariats de collaboration entre les entreprises pétrolières et gazières et leurs fournisseurs, travaillant ensemble pour améliorer continuellement la qualité et garantir la croissance durable de l’industrie.
Instructions: Choose the best answer for each question.
1. What does Process Average (PA) measure in the oil and gas industry? a) The average cost of producing a unit of oil or gas. b) The average number of defects per hundred units of product inspected. c) The average time it takes to complete a production process. d) The average amount of oil or gas extracted per day.
The correct answer is **b) The average number of defects per hundred units of product inspected.**
2. Why is Process Average a crucial indicator for oil and gas companies? a) It helps determine the amount of profit generated from oil and gas sales. b) It indicates the effectiveness of marketing campaigns for oil and gas products. c) It helps identify potential quality issues, negotiate with suppliers, and improve quality. d) It helps predict future oil and gas prices.
The correct answer is **c) It helps identify potential quality issues, negotiate with suppliers, and improve quality.**
3. How is Process Average calculated? a) (Number of Defective Units / Total Number of Units Inspected) x 100 b) (Total Number of Units Inspected / Number of Defective Units) x 100 c) (Number of Defective Units / Number of Defective Units + Total Number of Units Inspected) x 100 d) (Total Number of Units Inspected - Number of Defective Units) x 100
The correct answer is **a) (Number of Defective Units / Total Number of Units Inspected) x 100**
4. What does a high Process Average (PA) indicate? a) The supplier's manufacturing process is producing consistently high-quality products. b) The supplier is using advanced technology and equipment. c) There are likely problems with the supplier's manufacturing processes. d) The supplier is offering a competitive price for their products.
The correct answer is **c) There are likely problems with the supplier's manufacturing processes.**
5. Which of the following is NOT a practical application of Process Average in the oil and gas industry? a) Assessing the quality of welding procedures for pipeline construction. b) Monitoring the quality of components in drilling equipment. c) Measuring the efficiency of oil and gas extraction methods. d) Monitoring the quality of valves and pumps in processing plants.
The correct answer is **c) Measuring the efficiency of oil and gas extraction methods.**
Problem: A supplier delivers 500 units of a specific valve for use in an oil processing plant. Upon inspection, 10 valves are found defective. Calculate the Process Average (PA) for this delivery.
PA = (Number of Defective Units / Total Number of Units Inspected) x 100
PA = (10 / 500) x 100
PA = 2%
Therefore, the Process Average for this delivery is 2%. This means that 2% of the valves supplied were defective.
