Customers at the Reef Marina will be filling their vessels' fuel tanks with an extra degree of safety with the installation of a new fuel storage and delivery system. 

Petroleum giant Exxon Mobil has maintained and operated the Marina's fuel system from its inception, and last week removed the four old below-ground storage tanks. 

The company dug out two 55,000-litre and one 15,000-litre diesel tanks and one 5,000-litre petrol tanks, which had reached the end of their operational lifespan and installed a new 40,000-litre above-ground double-bunded diesel tank, which delivers fuel through a brand-new double-walled line system complete with electronic leak detectors and a self-serve bowser. 

Exxon Mobil also carried out a complete remediation of the belowground tank site, finding a minor amount of fuel in the very top layer of the soil around the tanks attributed to user spillage and no evidence of below-ground leaking. 

Marina general manager Rob Cruz said the Marina was working with Exxon Mobil and Douglas Shire Council to ensure the new fuel system delivered safer and more efficent operation. 

"Exxon Mobil has come through and done a very thorough inspection and remedation of the site and they are going to continue that process in the future," Mr Cruz said. 

"We want to make sure that the Marina is a safe and environmentally friendly environment and obviously updating the fuel system is one of the most important ways we do that."
