FUELS & OILS of fuel storage. The dispensing equipment needs to deliver about 800 litres per minute, because it’s filling 3,000 litre tanks and high-flow equipment means faster refuelling and cost and productivity savings. There’ll also need to be separate refuelling points for the lighter vehicles.” Security is another key consideration – Cygler says while fully automated and robotic refuelling is probably still a few years away for most sites, advanced fuel management systems have significantly streamlined the refuelling process and dramatically reduced losses. Having access to real-time data and analytics allows for predictive maintenance processes that reduce vehicle downtime. “AVI refuelling, or automated vehicle identification systems, identify each vehicle and monitor fuel usage. They can compile detailed data that includes who is operating the vehicle and changes in fuel consumption,” he says. “Fuel management systems provide an important basis for fuel management and are also an effective way to reduce theft and wastage.” Robofuelling SCOTT Automation’s ROBOFUEL™ is an automation and control solution, combined with the latest vision and sensing technologies providing refuelling of mine trucks accurately, safely and autonomously. The ROBOFUEL process uses a robotic arm to refuel mining equipment to increase productive hours and efficiency of trucks, with a projected business case that demonstrates a short payback period and deployment models that can be supported by either capital or operational initiatives. Typically, refuel facilities are manned by at least one person at all times and trucks can spend up to one hour per day travelling to refuel. As there is no manning required for an automated solution, refuelling stations me be optimally located “on-circuit” or even “in-pit” so fleet productivity can be significantly enhanced. ROBOFUEL is fully portable and is able to be shifted throughout mine developments allowing for the innovative technology to be placed where it is exactly needed, thus constantly working with the site. The company told IM that the autonomous truck installation it completed last year in the Pilbara iron ore mining region of WA achieved site acceptance in late 2019 and is now operating successfully in production. SCOTT is also seeing strong interest from the client for further systems across several other WA operations. The next project is also underway, for another WA iron ore SCOTT Automation's ROBOFUEL delivering fuel to an AHS mining truck in the Pilbara producer, and is due for completion in late 2020. This will include improved interfacing with the autonomous haulage system, and SCOTT is in collaboration with the AHS system providers on the system integration. Most of the design changes to accommodate AHS trucks have been around the remote interfacing with the vehicles, and improved remote connectivity with operations and maintenance personnel. Globally SCOTT added that there is strong interest, particularly across Australia and the Americas, and it expect several more of these projects to progress in 2020. Universal Field Robots (UFR) has come out with Chevron launches Texaco Delo 600 ADF oils The newly launched engine oil Texaco Delo 600 ADF from Chevron includes a “revolutionary” new additive technology and product line designed to significantly reduce diesel particulate filter (DPF) clogging; extending DPF service life by up to 2.5 times for a 3% fuel economy retention advantage over the life of the equipment. Texaco Delo 600 ADF with OMNIMAX™, a Chevron patented technology, the company says is the first heavy-duty engine oil with the capability to drastically reduce soot build up in DPF filters, “helping deliver outstanding system protection to both the engine and the emissions system. Suitable for both on and off-highway application, Texaco Delo 600 ADF with Chevron’s patented OMNIMAX™ technology, is formulated with only 0.4% sulphated ash – far lower than the API and ACEA limit of 1% sulphated ash, as found in many current heavy-duty engine oils.” This new product line and additive technology helps drastically reduce the rate of DPF clogging, resulting in extended DPF service life, less frequent DPF regeneration cycles, and contributing to a 3% improved fuel economy over the life of the equipment. Development of Texaco Delo 600 ADF came on the back of a desire to help ensure customers were able to achieve lowest possible running costs, and to meet emissions regulations, for off-highway applications. Stage I European standards for engines used in Non-Road Mobile Machinery (NRMM) were implemented in 1999, and over the years the requirements for NOx and particulates have become more stringent, helping equipment become far cleaner. Whilst Stage III and Stage IV led to limited use of DPFs, Stage V is driving widespread adoption of DPFs, which can be very effective at reducing particulate matter emissions but are subject to periodic cleaning to remove incombustible materials that accumulate over time. Rommel Atienza, Chevron Global Commercial Brand Manager, said: “The downside of DPFs is their operation inherently increases fuel consumption to assure that enough heat is generated to burn off the accumulated soot. This comes at a cost, not only the upfront cost associated with these devices and the numerous sensors and dosing units that enable them, but also ongoing operational and maintenance costs.” He adds: “Texaco Delo 600 ADF significantly reduces the rate of DPF clogging, to extend DPF service life by up to 2.5 times, resulting in a 3% fuel economy retention advantage over the life of the equipment and delivering significant savings to customers.” The full Delo 600 ADF line was available from July 1, 2020 and includes Delo 600 ADF 15W-40 and Delo 600 ADF 10W-30.
