Process safety

Process safety management is about keeping hazardous substances in pipes, tanks and vessels so they do not cause harm to people or the environment. It starts with designing and building projects and is implemented throughout the life cycle of the facilities to ensure they are operated safely, well maintained and regularly inspected.

In line with industry standards, we measure and report process safety incidents according to significance, with Tier 1 as the most significant category.

[A] Process safety events are classified according to guidance from the International Association of Oil & Gas Producers and the American Petroleum Institute. In 2022, there were three Tier 1 sabotage-related events. The classification of sabotage-related process safety events is made on the best-endeavours basis.

The number of Tier 1 and 2 operational process safety events in 2022 decreased significantly compared with 2021. There were 66 events reported during the year compared with 103 in 2021. The decrease was partly due to divestments, as well as improvements in work processes and using data to enhance safety planning.

Process safety events related to sabotage and theft in Nigeria are recorded separately. In Nigeria, there were three sabotage Tier 1 events in 2022, compared with seven sabotage events in 2021.
