European gas infrastructure firm N.V. Nederlandse Gasunie and professional services company Accenture have implemented a new digital natural gas transport management system (GTMS) to facilitate safe and secure operations of the Dutch gas grid.

Gasunie manages and maintains the infrastructure for large-scale transport and storage of gas in the Netherlands and the northern region of Germany.

The new digital system operates at the critical and complex gas infrastructure of the Netherlands. It is designed to better control the Dutch gas network via which Gasunie transports natural gas, hydrogen and green gas from biomass.

Including new supervisory control and data acquisition (SCADA) and gas management system (GMS) functions, the system is claimed to deliver control-room dispatchers and maintenance personnel with correct information at the exact time, 24 hours a day.

The SCADA and GMS functions aid the remote communication with Gasunie assets and equipment, along with distribution management systems and energy management systems in electricity grids.

“The new system is cheaper and easier to maintain on a daily basis, and the system’s flexibility will enable Gasunie to easily respond to any future changes required.”

Based on the information gathered, the GTMS generates insights and notifications, providing operators with all the data required for the operation of the gas grid from the central control room in Groningen.

Based on Schneider Electric’s advanced gas management system software, the GTMS provides Gasunie with real-time insights into the high-pressure gas grid, makes gas demand forecasts up to and including 48 hours in the future and offers simulations of gas flows and composition.

It is integrated with Gasunie’s geographical information system and uses a single source for asset data, including pipelines, compressors and valves, to create a network model of the system as a digital copy of the physical network.

In order to build the new system, Accenture and Gasunie implemented the functional architecture and applications and migrated data from the prior system.

Accenture also provided organisational change-management services to help prepare, train and support user groups, including dispatchers and data and IT maintenance teams, for the system implementation.

Accenture managing director for transmission and distribution business in the Netherlands Roy Ikink said: “This project will help optimise gas transport in the Netherlands, providing more insight into and influence over the Dutch gas grid, with greatly improved situational awareness for operators.

“The new system is cheaper and easier to maintain on a daily basis, and the system’s flexibility will enable Gasunie to easily respond to any future changes required. We are excited to continue our long-standing relationship with Gasunie.”
