Introduction: The objective of the proposed innovation project is to demonstrate interactive models of current and future corrosion risk using predictive analytics on a site of strategic importance on the NTS (National Transmission System).

Objectives:

Business objective to proactively intervene in a cost-effective manner for corrosion related issues through robust time based modelling.
Optimise the planning of remediation works on a site leading to a proactive rather than reactive response.
To reduce corrosion related intervention costs by at least 10% in RIIO T2

Expected Benefits: Potential saving of £60m across the NTS over RIIO-2 including up to £15m at St Fergus.
