Royston systems help CalMac meet emissions target

Mon, 04 April 2016

Innovative fuel management technology is helping Scottish ferry operator Caledonian MacBrayne (CalMac) meet its targets for the reduction of greenhouse gas emissions.

Last year the company installed Royston enginei fuel management systems across its entire vessel fleet as part of its Project Ecoship programme to improve fuel consumption and reduce emissions by a target of 2%.

Drew Collier, CalMac’s operations director, explained: “Our target is to make a two percent reduction in our release of carbon dioxide into the atmosphere. At the moment, we are confident that we are on track to achieve this and, importantly, we now have the technology in place to make accurate measurement.”

The enginei monitoring system uses Coriolis flowmeters and sensors to 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 and chief engineer to make small adjustments in real time to reduce fuel consumption.

CalMac has now reported that initial results from the programme are encouraging and it is on track to meet its emissions reduction target, with the engine operational adjustments not affecting journey schedules and timetables.

“We are finding some encouraging results. While it is too early to reveal any kind of scientifically concrete data, the initial figures we are seeing, as well as the anecdotal feedback from the teams on board, are optimistic,” said Mr Collier.

The first of CalMac’s ships to have a fuel management system fitted was MV Caledonian Isles and the vessel has now been operating with it for some seven months. The company considers that it is still in a bedding-in phase, with on-going learning by the crew and system software updates being made.

If, as it expects, CalMac meets its emissions targets, the installation costs of the ten enginei systems fitted to fleet vessels will pay for themselves within 12 months.
