Finding latent failures and root causes of accidents is the only way to stop the recurrence of such incidents, hence leading to improve our business.
Tripod-BETA helps you achieve that by analysing all kinds of incident investigations in a systematic way with the help of PC software.

What is Tripod?

Tripod is an approach to safety aimed at the underlying problems that lead to incidents. The Tripod theory, and the applications that have developed from it, are the result of research by the Universities of Leiden and Manchester, sponsored by Shell. The Tripod theory emphasises that the immediate causes (unsafe acts, people's errors), do not occur in isolation but are influenced by external factors - organisational or environmental preconditions. Many of these factors themselves originate from decisions or actions taken by planners, designers or managers that are far away from the scene of the accident - the latent failure. The latent failures will by their nature usually impact on a broad front. Hence, identifying and addressing them will bring wider benefit when compared to the immediate cause of the accident.

What is Tripod-BETA?

Tripod-BETA is a methodology for conducting an incident analysis in parallel with the investigation, supported by a PC based tool. Feedback from analysis provides the investigators with the means to validate findings, confirm the relevance of hazard management measures and identify new investigation possibilities. The Tripod-BETA method promotes thorough incident investigation with clear, concise and consistent reporting. It was introduced in PDO initially for analysing Fatalities, and later extended to cover the analysis of high potential incidents. Tangible benefits have been realised as the report writing time has significantly reduced, and the quality of corrective actions has improved.

Tripod-BETA tool is a tree approach to the analysis of accidents and incidents. It focuses initially on the accident mechanism (the facts concerning the events and their consequences, including the potential consequences) and uses it as a structure to identify the hazard management measures (the controls and defences) that should have been in place. For the incident to happen the hazard management measures either failed or were missing. The investigation and analysis therefore examines the immediate and latent (organisational arrangements, remote or underlying) failures behind each missing or failed hazard management measure, and proffer action items to address them. The latent failures will by their nature usually impact on a broad front. Hence, addressing them bring wider benefit. Also, actions addressing the immediate causes (the active failures) may have lateral applications in other operations, thereby the other operations gain the benefit without going through the experience of the incident.

Who are the target users of the Tripod-BETA tool?

The target users are PDO and contractors staff who are likely to be involved in incident investigation, especially the HSE Advisers and the key staff that are required to lead or facilitate those investigations.
