RISKWISE for Process Plant™ used by Associate Partner in Italy Donegani Anticorrosione, one of the most important Italian companies in the field of inspection and NDT services, has carried out an RBI study on a Polyethylene gas phase plant using RISKWISE for Process Plant™.
The aim was to develop a criticality ranking of the plant equipment and to prepare an inspection plan focusing on the most critical items. The plant is relatively new and the historical data are relatively few. Donegani Anticorrosione based the assessment on the previous inspection data and utilised the experience of plant engineers The plant process is relatively non-aggressive, being gas phase, with relatively non-critical fluid and mild process parameters, i.e. temperature and pressure. Attention concentrated on the possibility of damage from external agents, such as corrosion under insulation and stress corrosion cracking as the plant is close to the sea. The application of the methodology to different kinds of process plant, demonstrated the usefulness of the RBI approach in optimisation of an inspection plan. Donegani Anticorrosione has future plans to use RISKWISE™ on ethylene cracking plant.
