Project Summary 

Jemena’s Northern Gas Pipeline Project stretches 622km from Tennant Creek to Mount Isa, delivering critical energy from the NT gas fields to Queensland customers. Synertec designed, supplied, and commissioned the process control and safety system for the $800 million pipeline project.

The Challenge 

Jemena required a control system incorporating remote onsite commissioning for its gas processing plant, compressor stations, and remote pipeline monitoring stations. The system also needed to comply to international functional safety standards.

Synertec Solutions 

Synertec provided the detailed design and supply of a large-scale PLC automated control system and flow computers, including electrical design and panel fabrication to meet the required functional safety standards. The design included Hazard And Operability Study (HAZOP) and Control Hazard And Operability Study (CHAZOP) assessments.

The system included integration of numerous plant packages and incorporation into Jemena’s Supervisory Control And Data Acquisition (SCADA) system to enable remote operations from Melbourne.

Synertec conducted factory acceptance testing on the control system and electrical panels in Melbourne prior to installation and commissioning. Site acceptance testing was also conducted on site at each end of the pipeline in Mount Isa and Tennant Creek,
and at monitoring sites in between.

Synertec successfully navigated the key challenges associated with delivering the project at remote sites in the Northern Territory and Queensland, and managing the safety aspects associated with remote sites and travel.
