As part of a ‘Project Ecoship’ policy to improve fuel consumption and reduce greenhouse gas emissions, Scottish islands ferry operator Caledonian MacBrayne (CalMac) is installing new ship fuel management systems on all of its major vessels.

In a competitive tender, Royston successfully proposed the installation of its new second generation Enginei fuel management system for the work.

The tender is linked to CalMac’s aim to save fuel and reduce emissions in ships over 2500 GRT by installing specialist fuel monitoring instrumentation to determine the most efficient operating parameters for individual vessels.

The recently upgraded Enginei system meets the need for more informed decisions to be made on marine fuel optimisation and fleet management matters by providing a range of powerful voyage and vessel data analysis and reporting options.

The system uses Coriolis flowmeters and sensors to accurately monitor the fuel being consumed by each of a vessel’s engines, which is tracked against GPS data, voyage details and operational mode.

The real time data is collected, processed and relayed to bridge and engine room-mounted touchscreen monitors to enable the ship’s master to adjust vessel speed and take whatever other actions are needed to reduce fuel consumption.

In addition, remote data access is provided for onshore teams through a secure online portal, with bespoke software and special reporting options enabling a comprehensive picture of fuel and vessel performance to be maintained.

The installation of the Enginei systems on the selected CalMac ferries began this summer. Eight of the 10 vessels concerned have had the system installed and the remaining two will be achieved during the routine annual maintenance period.

The work has been carried out at different Scottish, Hebridean and Western Isles ports in keeping with the ferries’ operational schedules.


“Our commitment to the taxpayer and the environment has come together with Project Ecoship,” said CalMac’s technical director Peter Breslin.

“The fuel monitoring systems have only recently been installed on our vessels and the project is in a bedding-in phase.
“But both early data and anecdotal feedback from the ships is encouraging and we expect to see significant benefits in due course both to our carbon footprint and our bottom line.

“For taxpayers and our shareholder, the Scottish Government, this has to be welcome news and is part of our on-going commitment to make energy and environmental improvements in line with the Scottish Government’s National Transport Strategy wherever possible.


In the start, I was frank with you propecia before and after has changed my being. It has become much more fun, and now I have to run. Just as it is incredible to sit.
