Case studies

Please find below a selection of case sudies from some of our clients.

Client requirement:

Client had existing flow meters installed on the main engines, however due to the sensitive environmental nature of where the vessel was to be contracted they wanted to prove to the charterer that they were doing as much as possible to reduce the environmental impact. A large part of this was to log and optimise fuel consumption. This required a visual display on the bridge in order to aid the Captain with efficient operation of the vessel. Bespoke enginei software was developed for the client both on the vessel and onshore to log how much fuel was consumed in each operating mode of the vessel such as Dynamic Positioning, Standby, Transit, Anchor Handling.

enginei was installed to log the consumption readings from the existing meters as well as installing new meters on the auxiliary engines. Three displays were then installed, two on the bridge forward and aft and one in the engine control room.


Client now has a complete and accurate picture of fuel consumption on all engines. The vessel and operations team now know how much fuel is consumed in various operational modes and the master can use this information to optimise fuel consumption in DP mode altering position depending on the weather conditions as well as transiting and other working modes.

The client now plans to fit all new builds with enginei

Client requirement:

Due to ever tightening emissions regulations and an increasingly difficult economic market the client had to start logging accurate fuel consumption data in order to optimise the vessel passages and have a reliable tool to contribute to their Ship Energy Efficiency Plan (SEEMP).

A tailored on-board enginei software package was developed with a touchscreen computer mounted on the bridge. The Captain now logs ports, times, bunker cost, loaded or ballast, voyage notes and weather. All this information is then tied into the fuel consumption data; giving the operator very detailed fuel reports and trends.


The client is now able to accurately establish a baseline consumption for its various passages and the optimum speed for those passages depending on weather conditions. They found after 6 months of recording the data that their recommended steaming speed was actually half a knot to a knot too high on certain classes of vessel. By finding that optimum speed they are now looking at considerable reductions on fuel consumption of up to 4% over 12 months.

All data is packaged as part of their SEEMP

Client requirement:

Driven by an industry trying to take action on a vast and complicated issue of fuel misuse and steered by the clients charterer, a solution was required where fuel consumption could be measured on all diesel consumers as well as measuring bunker loading and discharge; providing the client a complete and accurate overview of fuel usage.

Coriolis meters were installed on the supply and return lines of all engines and a bi-directional meter installed on the main load and discharge bunker line. Via a small fuel gauge in the wheelhouse enginei software gives the crew daily total fuel consumption and bunker totals. This figure is then used by the Captain to log their consumption for the charterer and is the exact figure that the charterer and the client sees remotely via the enginei online management website. There are now no discrepancies over fuel usage between the vessel and the operator and the charterer


Time consuming paperwork and communications between the charterer and the operator over fuel consumption discrepancies are now solved.

Significant reductions in fuel usage have been seen.

The charterer is satisfied and the client is winning more contracts.

Client requirement:

The operator sails more than 130,000 separate sailings a year to 24 destinations. As part of a wider policy to improve fuel consumption and reduce greenhouse gas emissions, they installed enginei's second generation ship fuel management systems on 10 of its largest vessels.

The fuel monitoring instrumentation helps determine the most efficient operating parameters for individual vessels and routes by giving the Captain an ETA application on the bridge display in which he can reduce: speed, rpm, pitch but still make the timetable schedule.

The system uses Coriolis flowmeters and torque sensors to accurately monitor the fuel being consumed by each of the 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 12" touchscreen monitors. Remote data access is provided for onshore teams through a secure online portal with a reports dashboard capturing data such as:
total consumption
consumption per passage
consumption and torque per engine
hours run
passage data such as Captain, passage start/stop, passengers and vehicles onboard and weather notes.
Giving the operations team a full picture of fuel and vessel performance.


Fuel savings seen on all routes

Positive change of behavioral attitude towards fuel and operational best practice

Greater visibility for operational management
