PM Policy: GU policy Requirements of planning & sales
Developing Policy
• Life Cycle Cost – based design, –based construction and maintenance
• Cover all threats • Deal with threats proactively • Maintain (national) risk standards • Set performance targets • Involvement in EU legislation & Normalisation
Design failures Delay in construction Material and / or construction failures
Operations: Inventarisation Opportunities
Threats Challenges Opportunities

Developing KPI methodology SMS presents in the European Gas Transmission Industry generally the same fundamental structure (Plan, Do, Check and Act). Principles and the architecture philosophy followed for the SMS are described in a document issued by the IGU (2003) (reference)
The management loop
SMS PLAN
ACT
PIMS
DO
The global process guarantees the system’s coherency by managing the loop.
CHECK PERFORMANCE INDICATORS
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 policies on a regular basis in order to plan the achievement of safety objectives.
