Safety results

Safety policy

Creating a safe and healthy workplace and minimising the risks to the environment and local communities are clear priorities.
We periodically report on our safety performance and systematically carry out analyses. We are constantly learning and we strive for continuous improvement. Among other things, we have established critical performance indicators with regard to incidents (Total reportable frequency index - TRFI) and the number of pipeline damage incidents.

Safety is an important indicator of the quality of our work. We were unable to continue the trend in improving our KPIs in 2018. Our KPIs show the following results:

Number of incidents and sickness absence

In 2018, 40 incidents occurred (2017: 32), of which 17 reportable incidents (2017: 16). This results in a TRFI of 3.4 (2017: 3.2). There were 7 incidents resulting in absence (2017: 7).

TRFI Gasunie Netherlands + Germany

The number of reportable incidents at Gasunie Deutschland remained low, at 4, while the number remained approximately the same at Gasunie Nederland: 13. The total number of hours worked by Gasunie employees and third-party employees (which are relevant for the calculation of the TRFI) rose very slightly from 5,017,696 to 5,032,601 hours.

Number of reportable incidents

Pipeline damage incidents

In 2018, 3 incidents of pipeline damage occurred as the result of a mechanical action (2017: 4). Two of the incidents of pipeline damage could potentially have resulted in pipeline failure and gas leaks. In these cases, an excavation contractor hit a Gasunie pipeline during excavating work. In 1 case, a regional pipeline became damaged during drainage work, resulting in gas leaks.

Total number of pipeline damage incidents

In order to prevent damage by excavation work, we ensure that the current location of our pipelines is on record with KLIC. The safe location of our entire network is inspected by helicopter every three weeks.

To safeguard the integrity of our pipeline system, we systematically inspect part of our pipeline system each year. In 2018, we inspected 125 kilometres of pipelines internally and 11 kilometres externally.


The Safe@Gasunie Experience was continued in 2018. This is a workshop in which the participants ‘follow an internship’ at an organisation resembling Gasunie. The results of this were as follows:

  • A mobile version of the Experience was developed and used to train employees in the updated work permit process. We also use the mobile Experience to train new employees in safety awareness.
  • In order to increase understanding of the processes and chains in which we work, we will be elaborating them in diagrams. Everyone can then see what links make up the process, who is responsible for what and what handover moments there are. The first chain concerns the work permit process. The second chain, which is in development, concerns the processes of carrying out projects and maintenance and the associated safety processes.
  • We conducted incident investigations that overarched individual departments, together with all the people involved. Everyone in the chain can provide input and insight is created into the facts of the situation, along with support for improvement measures.

A programme was started to promote (safety) leadership among managers as a pilot in the Operations department.

Other components of Safe@Gasunie that we are constantly working on include:

  • the publication of Informative Incident Bulletins;
  • the ‘Veilig Werken? Zeker Weten!’ [Working Safely? Absolutely!] campaign, which was used to reinforce the ideas of the Last Minute Risk Analysis;
  • campaigns directed at specific parts of our Safety, Health and Environment policy. For instance, at the end of 2018 we started a traffic safety campaign. In addition to general information, employees are given the opportunity to use driving simulators to gain insight into their driving behaviour.

Feed-in of new and different gases into the existing gas transport system

Gasunie is contributing to the energy transition in all sorts of ways. When it comes to safety, an internal knowledge/expertise centre is being set up to properly assess the impact concerning safety aspects of different/new gases (including those coming from biogas/gasification plants, green gas, hydrogen) on the existing gas transport system, including the consequences for risk contours (QRA, calculation models). A great deal of attention is being devoted particularly to the transport of hydrogen and CO2. A testing and training facility (TOF) is being set up for hydrogen and other gases.
