Mesea on track to reach zero high-potential incidents through strategic collaboration with dss⁺

Villognon, France, 12th April 2023

Since 2017, Mesea has been the first private operator in charge of maintenance and operation of the high-speed train line infrastructure between Tours and Bordeaux. In 2018, Mesea asked for dss+ support to deploy a safety policy targeting high performance, aiming at understanding and eradicating High Potential (HiPo) events. dss+ assessed, elaborated and proposed a strategic tailor-made action plan with 2 focus areas: risks awareness and safety leadership development for managers and all employees. This resulted in a 60% reduction of high-potential incidents and a decreasing of total recordable injuries (LTRI) by 10 over a 3-year period.

Mesea partnered with dss+ to understand the root cause of the HiPo incidents, which are classed as ‘near misses’ whereby the incident could have resulted in serious injury or even fatality. The challenge Mesea faced had 3 complications the railway maintenance workforce was distributed over a large territory, work was mainly carried out at night, and in all weather conditions. dss+ used their expertise to analyse dangerous situations, develop a risk profile and zero-incident action plan called ‘All Preventers’ which involved all leaders, managers, and the entire workforce.

Jean-Bruno Delrue, CEO of Mesea, said: “Mesea ensures that 20 million passengers travel safely along the +300km railway between Paris and Bordeaux. But we must also ensure the safety of our maintenance workforce who work in challenging conditions. We must mitigate the risks to avoid what could potentially be serious incidents, but we knew we couldn’t do this alone. dss+ assessed our safety culture and from that we worked together to implement the necessary changes, where through training and coaching we have transformed our safety culture. Results speak for themselves. We are all feeling optimistic that our ambitious zero-incident target can and will be reached.”

dss+ work with organisations around the world to help them to recognise, evaluate, and mitigate their risks so that they can work safer, smarter and with purpose. Mathieu Leduc, EMEA Director of Industries & Practices at dss+ explains: “Transforming safety culture is not just about enforcing rules and procedures or removing hazards. It must start with the people, changing attitudes, empowering people and taking ownership for their own actions and the actions of others. That’s exactly what we focused on with the ‘All Preventers’ programme. By enhancing the capabilities of everyone you can increase both risk management capabilities as well as risk awareness and mitigation skills of all staff. Through a risk-aware, engaged culture you can transform safety and ultimately save lives.”
