Bringing more gas to market in Roma North


Zinfra and Jemena have been working on the capacity expansion of the Roma North gas processing facility from 16 terajoules a day (TJ/d) to 24 TJ/d, helping to meet global demand.

The $15 million expansion will also Jemena to deliver increased flows from Senex’s Roma North gas field to market, with capacity of the facility is expected to increase by about 50 per cent.

As a trusted delivery partner to Jemena, the Zinfra gas projects team is handling the project management, procurement, construction management and commissioning, which also includes the approvals of engineering deliverables.

In gaining the capability to deliver major gas transmission projects, Zinfra now has the full proficiency to deliver services and projects in both transmission and distribution, for gas and electricity markets.

Being a transition project, Jemena also engaged Brisbane-based Wasco to undertake the construction component for the expansion, with Zinfra managing the full implementation of this component to completion.

According to Zinfra project manager Justin Anderson, Wasco were engaged after winning a competitive tender for the works, based upon their past experience – they built the original Roma North compressor station for Senex – as well as its local presence, capability, price, schedule and adherence to commercial terms.

Peter Iancov, managing director of Zinfra, said that gaining the capability to deliver major gas transmission projects is completing the full suite of capability that Zinfra can offer to the market. Now, Zinfra has full capability to deliver services and projects, in both transmission and distribution for gas and electricity markets.

He said this project is a particularly good example of Zinfra working with an upstream gas owner/operator (Senex) and a midstream infrastructure owner/operator (Jemena) to develop Queensland’s gas reserves.

“Senex relies on Jemena as its trusted midstream infrastructure partner to process its gas and deliver it to the market; and Jemena relies on Zinfra, as its trusted project delivery partner, to turn a conceptual scope of work into a fully constructed and commissioned asset that is holistically integrated into the Jemena business,” Iancov said.

“We have highly skilled and experienced people and very well developed systems and processes that give Jemena and our upstream partners confidence that we are going to deliver the project safely, to a high standard, and on schedule, every time.”

Zinfra has a focus on continuous improvement, and Iancov said that the team has incorporated many lessons learned in both project delivery and operation and maintenance from the original Roma North plant, as well as the Atlas compressor station, into the works they are executing as part of the Roma North expansion.

In particular, improvements in functionality have been achieved, which will allow the compressors in Queensland to be remotely operated in Zinfra’s control room in Melbourne. 

Work on the expansion commenced in mid-2021, when design was completed and long-lead items were ordered.

Construction is now halfway to completion, and gas will be exported from the new compressors in September 2021.
