EDF Energy is the UK entity of EDF Group and consists of several Business Units with activities ranging from Power Generation (through Nuclear, Coal and Gas stations) to Metering and Customer facing Contact Centres. This project will focus solely on the activities of EDF Energy’s two coal-fired power stations in Nottinghamshire - Cottam and West Burton A.
Incident reports at EDF Energy are categorised into 3 levels, “Incidents (I)”, “Serious Incidents (SI)” and “Very Serious Incidents (VSI)”. This project is aimed at identifying the key casual factors of SIs. Current analysis of such incidents mainly consists of manually making use of existing incident reports and near-miss data.
Spreadsheet-based reporting tools have been developed in-house to conduct basic slicing and dicing of data to identify trends and to display information through changing key variables. However, this is high-level with no linking of alternative data sets beyond incident reports.
Beyond this, more detailed analysis is carried out which is reliant on human business expertise rather than predictive analytics and software modelling to look for deep correlations and causal factors.
There is a wealth of information relating to health and safety performance data from the 2 power stations. Five core sources of data have been identified which are likely to be key to the modelling, these are:
- Incident Reports
- Dip Check Reports
- Safety Observations
- Audit Reports
- Inspection Reports
These data sources contain a wealth of historical data, incident data alone dates back several years with thousands of records.
The data sources outlined above contain both structured and free text data and are not an exhaustive list of the information held by EDF Energy relating to health and safety. Other data may be available upon request to support the modelling approach such as card swipe reports or staff demographics.
Successful delivery of this ‘proof of concept’ exercise will see EDF Energy gain new insights into the factors which contribute to the occurrence of serious incidents.
