Eniram Releases New Fuel-Saving Tool

Eniram Engine is said to be intended to help use fuel as efficiently as possible.

Eniram Ltd (Eniram) has announced the release of Eniram Engine, a new tool designed to help owners and operators of LNG Carriers with tri-fuel diesel electric propulsion systems (TFDE) improve fuel efficiency by 2 to 4 percent.

"High engine efficiency is imperative in order to achieve low SFC and cost savings," explained Eniram, noting that the tool uses real-time engine operation factors, including "data from onboard fuel flow meters with generator loads, power produced, and Specific Fuel Consumption (SFC)."

The tool is said to then use the data to recommend the most efficient engine combination and fuel type in order to glean an optimised fuel savings.

"Monitoring the available power is critical for safe and efficient operations on board," explained Jussi Pyörre, CTO at Eniram.

"Eniram Engine demonstrates that even small changes in engine use pattern during a voyage can have a significant impact in reducing fuel and overall operating costs.

"Based on our analysis, ship owners will be able to achieve a reduction of 2 percent to 4 percent of total fuel consumption."

Eniram Engine is said to take into account the different operating modes of LNG carriers.

"When fuel oil is used to supplement Boil-Off Gas (BOG) as a fuel for the ship's propulsion and energy systems, Eniram Engine will provide guidance only with this mixed fuel usage," explained Eniram.

The Eniram Engine is also said to have a buffer feature that can provide engineers with an estimate of how much operating reserve power is available for each engine suggestion compared against the actual.

In September, Eniram announced the release of three new ship efficiency solutions, including enhanced speed optimisation and optimal routing solutions, as well as new Performance 3.0 data analytics software for cruise vessels.
