When it comes to safety, one of our ambitions is to structurally reduce the Total Reportable Frequency Index (TRFI) to below 3.0. The TRFI is a measure of safety performance based on a ratio between ‘reportable’ accidents and total hours worked.
The TRFI exceeded the signal value at the end of 2018 in the number of reportables. The TRFI dropped back to below the signal value during the first six months of 2019. The current value for the period from July 2018 to the end of June 2019 inclusive is 2.6.
When it comes to the number of pipeline damage incidents with gas leaks or the potential for gas leaks, the signal value was set at fewer than 5 for 2019. So far in 2019, there have been no cases of pipeline damage with gas leaks or the potential for gas leaks. At the beginning of January, a siphon was damaged at Walibi theme park in Biddinghuizen, and there were gas leaks. The pipeline itself was not damaged, and as a result, this event technically does not satisfy Gasunie’s definition of a pipeline damage incident. This event has prompted us, however, to investigate whether the definition of pipeline damage incident that Gasunie has used for years should be changed.
