Direct data via satellite

Similar concerns have motivated Singapore based Ascenz to develop its Remote Fuel Monitoring System, which aims to collect fuel consumption data for ongoing or routine monitoring, as well as enabling operators to compile key performance indicators (KPIs) to assist with future decision making.

Chia Yoong Hui, director and CEO of Ascenz, says: “Bunker fuel costs were low before 2008, but we’ve this year seen prices shoot up to US$154 a barrel. In 2007, fuel accounted for approximately 20% of total operating expenses, but this has rocketed to 60% at the very minimum. Without reliable data, it becomes difficult for operators to make predictions for fuel economy. For instance, when tank dipping, just a small 0.25% error in the reading can equal more than US$7000 in costs.”

In contrast, the Remote Fuel Monitoring System transmits fuel consumption data, gathered from an on board flow meter directly to the Ascenz website, via satellite, where customers can log in to access the data. Information includes vessels location and engine status, as well as density, mass flow and temperature of the liquid fuel at any given time, enabling operators to monitor rates of consumptions, both hourly and daily.

Voyage long monitoring

The incorporation of a flow meter into the set-up also eliminates the need to fly engineers out to the vessel, with the info being relayed over a satellite terminal (most commonly via Inmarsat services, Chia tells Offshore Marine Technology) back to shore.

Chia Claims that users can also access the website’s ‘history track’ function to check the vessel’s past movements on a map display, enabling operators to calculate at which sections of the voyage, at which locations and under which conditions the most fuel was spent, and to translate these patterns into KPIs to set standards for future operational practice, including the ideal RPMs to slash fuel consumption while still arriving on time. As Chia says: “A KPI for fleet fuel consumption could prove a good strategy to keep costs low and stay ahead of competitors.”
