Royston Automates Vessel Mode Detection for Improved Bunker Consumption Monitoring

Royston's Engenei is now able to automatically identify a vessel's operational mode, eliminating human error to more accurately analyse fuel consumption.

Royston says that, in conjunction with marine engineering specialists from Newcastle University, it has developed a new version of its Enginei marine engine monitoring system that automatically identifies a vessel's operational mode, which when used results in more accurate fuel consumption when compared to manual inputs, Offshore Support Journal reports.

As such, the Enginei update enables onboard engineers and offshore fleet management staff to make more informed and accurate decisions related to fuel consumption.

The automatic mode detection feature is said to have been developed using trials undertaken in partnership with GulfMark Offshore, Inc. (GulfMark), an offshore vessel (OSV) owner, which facilitated the testing of the updated system on the GulfMark's Highland Prince.

"The tests we have undertaken on the new enginei auto-mode detection capability have been very successful. The auto-mode identification was very accurate, enabling close correlation between the different types of vessel operational activities with specific fuel consumption rates," said Jim Bradford, general manager of operations for GulfMark Offshore.

"The automatic logging of vessel activity type will mean that the crew and onshore staff can identify not only the mode of operation but the time spent in each mode."

Bradford explains that the automatic mode detection feature enables more effective voyage planning, ensures the vessel can be operated at speeds that facilitate optimum fuel consumption, and allows for accurate measurement of CO2 and other emissions.

"Importantly, having more accurate performance data will also enable us to look at the actual working hours of individual engines, enabling us to more effectively balance their use at optimal levels of power output and to prioritise service and condition-based maintenance requirements," added Bradford.

In February, Royston said that international oil companies' "growing insistence" that oilfield contract vessels be fitted with fuel monitoring systems, despite the current low price of fuel, has spurred and increased interest in marine engine monitoring systems.
