To better control HSE risks of its complex operations, TOTAL E&P Angola hereinafter referred as TEPA (4 FPSOs, 630 kbopd in 2017) developed an Operational Global Risk Dashboard to provide a summary HSE view of operating sites. The tool was set to assist Top Management's decision making from risk trends and to identify situations displaying areas of concern.
While the first dashboard was composed of an exhaustive set of measurable data, its benefits were balanced by the delay and efforts spent to update it. The tool was rationalized by focusing only on two key components: the reliable data available in the Company HSE web database and the risk perception of the HSE Site Managers, responsible of HSE on site.
The dashboard consists of a global risk view which summarizes the operational risk indicators and a detailed risk view per asset. A qualitative risk evaluation of numerical data was considered, capturing the cumulative effects as a combination of three simple dimensions: quantity, criticality and trend. Four operational risk indicators cover the incidents recorded, with 3 different viewpoints (human consequences, high potential incidents and loss of primary containment) and the downgraded situations.
The risk perception of the HSE Site Manager is built through three major drivers of asset integrity: people, plant and processes. It is a valuable soft indicator, often complementary from the data analysis. It captures all the weak signals from the sites which might not be reflected within all the trends of available data.
The display with colored icons (green, orange and red) gives an immediate perception of the risk. It supports the Top Management to check if the appropriate corrective actions are undertaken by the operational entities or at least requesting additional risk mitigations on the identified red warnings. It also provides a qualitative means to analyze which parameter of ‘People, Plant & Processes’ needs to be reinforced.
