The Project must solve the correct problem without creating new ones

It Must Be Operable

• Operations must be able to Energy Isolate the install safely
• Operations must have adequate and accessible valving, controls, process equipment and etc required for Energy Isolation
• Operations must be able to start-up/stop the project anytime and under any circumstances, safely

It Must Be Reliable

• Must be able to start-up safely and in a controlled manner at all times, without damaging the process equipment
• Must be able to be shut-down safely and in a controlled manner at all times, without damaging the process equipment
• Emergency Shutdowns must be done safely and in a controlled manner at all times, without damaging the process equipment
• Must be able to run with minimal to zero operational interface — once it starts, it should just operate

It Must Be Maintainable

• All equipment parts must be purchasable by maintenance for repairs
• All critical spare parts should be purchased as part of the project and on-site for maintenance
• Maintenance should have vendor training to be able to repair all equipment
• All equipment must be accessible with appropriate lifting devices so maintenance can remove equipment without destroying the module
