ExxonMobil Australia subsidiary Mobil Oil Australia plans to increase fuel storage capacity at its Adelaide terminal with the construction of new 9 million litre diesel tank.

Mobil's facility at Birkenhead is one of three key fuel distribution terminals operated by Mobil in South-Eastern Australia and is a principal point of supply into South Australia.

Mobil Birkenhead currently handles the greatest annual volume of petrol, diesel and aviation fuels of any terminal in South Australia and this new tank will increase the overall storage capacity of the terminal by more than 10 percent, the company said.

This new tank adds to Mobil’s investment of over $20 million in its Australian fuel terminal infrastructure since 2008.

The Birkenhead terminal is operated by Mobil on behalf of joint owners Mobil and Shell and occupies 15 hectares of land between Victoria Road and Elder Road, Port Adelaide. Mobil has been making significant investments at the terminal in recent years to ensure that it can continue to operate reliably and in an environmentally responsible manner well into the future.

Construction of the litre tank is expected to take approximately 12 months to complete and will commence following receipt of local planning approvals.
