6 Benefits of an integrated Flow Assurance Monitoring System Integrated technical solution: Products integrated using same of coordinated field cabling, one cabinet, one server and one user interface (Fieldwatch) Project Management One project manager, one project, minimized interfacing between suppliers, one documentation package, One supplier for installation and commissioning services After Installation One supplier for spare parts One user interface, less personnel training for operations and maintenance. Healthcare and maintenance contracts. 27-Jun-01, Slide 6

7 Why Internal Corrosion Monitoring? Corrosion Management Correlate process parameters with measured corrosion Monitor (change in) corosivity of pipeline fluids Control of corrosion mitigation/inhibitors High resolution and fast response required from the sensor. Integrity management and safety verification Risk of unexpected failure and accidents Avoid loss of containment Optimize (risk based) inspection programs and planned maintenance Reliable wall thickness measurements over time required, high resolution/fast response less important. 27-Jun-01, Slide 7
