Integrity Management:

Right of way • Mobile inspections (walk, drive, fly)• Supervision “Third party jobs”

(KLIC)• Preventive measures

IntegrityCorrosion prevention

• Cathodic Protection• Coating (primary protection)• Stray currents drainage

Inspections of condition

• Intelligent Pigging• CP control measurements• Coating inspections

Integrity Analysis• (Direct) Assessment

PERFORMANCEINDICATORS

The global process guarantees the system’s coherency by managing the loop.

In the global process an important role is played by the Performance Indicators that shall support the Operator in measuring and monitoring the implementation of environmental and safety policieson a regular basis in order to plan the achievement of safety objectives.
