Saft batteries to protect a new gas pipeline between Algeria and Tunisia

07 November 2018

Saft has been awarded a contract by Spie Oil & Gas Services to provide nickel-technology batteries to power corrosion protection systems on the Hassi R’Mel gas field pipeline.

The Saft batteries will be installed at 34 stations along the pipeline where they will store energy from solar panels to keep the cathodic protection systems operating for up to five days.

Frédéric Belougne, Project Manager at Spie Oil & Gas services, says: "Thousands of batteries are already installed at remote locations across the globe that rely on solar power, notably in the Middle East where Saft’s nickel-technology has forged a reputation as a reliable, long-lasting solution. Spie Oil & Gas services chose batteries for this particular project for their excellent cycling capacity and suitability for remote facilities where regular maintenance procedures often prove to be both arduous and costly".

The Hassi R'Mel gas field is located around 550km south of Algiers in the Sahara Desert. Discovered by the French Oil Company in Algeria in 1956, this gas field currently represents a quarter of the country's total gas output.

The Saft batteries will provide each of the 34 stations along the Hassi R'Mel pipeline with some 100 Watts of power. This will support the corrosion protection systems across the 1,650km pipeline, which stretches from the Hassi R'Mel gas field in Algeria to the Qued Saf-Saf on the Tunisian border. The pipeline then feeds into Transmed’s supply link between Tunisia and Italy to provide Europe with gas.

During the daytime, the solar photovoltaic panels used in conjunction with the batteries will provide a constant supply of electricity for the SCADA (Supervisory Control and Data Acquisition) and cathodic protection systems. The solar panels will also charge the Saft batteries and they will be discharged to maintain a continuous supply of electricity during the night.
