Training in Oil & Gas Production for BP Technical Interns Management of change (MOC) 1. Determine need for a MOC request. 2. Complete paperwork for MOC request. 3. Request goes to engineering review 4. Request goes to an HSE review 5. Request may go to other reviews 6. Ops manager must sign off on request 7. MOC approved and change may begin

Training in Oil & Gas Production for BP Technical Interns An MOC policy means Without an MOC any production equipment needing replaced down to the least significant pipe fitting must be replace with an identical items with identical specifications. Example: Replace a 2” steel 5000 PSI ball valve with only another 2” steel 5000 PSI ball valve. Manufacturer may vary.

Training in Oil & Gas Production for BP Technical Interns Pitfalls in pipelines & fittings Using low pressure fitting in high pressure. Using low pressure fitting in high pressure. Shock impact of HP gas with ¼ turn valve. Shock impact of HP gas with ¼ turn valve. Failure to determine direction of flow. Failure to determine direction of flow. Internal erosion of pipe and fittings. Internal erosion of pipe and fittings. Poor engineering for environmental change Poor engineering for environmental change Cross threading or short threading Cross threading or short threading Internal/external corrosion problems Internal/external corrosion problems
