Gas pipeline in river to be protected by concrete mattresses

THE Sydney-based company in charge of transporting gas from Mount Larcom to Rockhampton is about to make waves on the Fitzroy River this week.

Jemena owns and operates the Queensland Gas Pipeline which transports gas - from the Wallumbilla gas hub, the Surat and Cooper basins, the Denison trough and the southern Bowen Basin - to large industrial customers in Central Queensland.

The customers include Queensland Alumina, Rio Tinto, Orica, Boyne Smelters and Queensland Magnesia.

In the wake of recent flood events in Rockhampton, Jemena has decided to protect the pipeline where it crosses the Fitzroy River by lowering several concrete mattresses on to the river bed and over the pipeline.

The pipeline is buried and crosses the Fitzroy River around Pink Lily/Kawana area. A spokesman for Jemena said this would ensure the gas supplied to Rockhampton homes and businesses is reliable and secure. Gas is also supplied to households and businesses through the distribution networks in Gladstone and Wide Bay and Rockhampton.

These concrete mattresses will ensure that when flood events occur, the pipeline will not be damaged by any increase in the flow of water.

Jemena has engaged a specialist contractor, Joseph Engineering, to install these mattresses. The contractor will use a 10-metre tug and a 15.2-metre barge to transport the mattresses before lowering them over the pipeline with a barge-mounted crane.

Rockhampton Ski Gardens boat ramp will be used to launch the tug. Jemena has consulted with the Rockhampton Regional Council to ensure this work does not impact on other boat ramp users. Installation will start on October 7 and should be finished by the end of the month.
