In order to save fuel you need to understand how your vessel is consuming it. A proven way of cutting fuel consumption and CO2 emissions is to optimize your vessel’s trim at all times. Eniram Trim helps your crew to maintain optimum trim and save money by using less fuel. Eniram Trim is designed to ensure maximum performance in actual variable conditions by collecting prevailing trim, propulsion power and vessel movement data.

Features & Benefits

  • Ensure savings in all loading and weather conditions
  • Increased vessel performance
  • Operational insight
  • Easy deployment and fast ROI

Hamburg Süd Saves Fuel with Eniram

“As a result of Eniram Trim™, the ship’s command is no way at the mercy of the design of the ship and the ambient conditions.

Hamburg Süd is one of the first container lines to use this system. Evaluation of the results revealed fuel economies of 3-5%.”

How Does it Work?

Eniram Trim uses vessel performance and attitude data including:

  • Trim, list, hull bending and sea state
  • Draft and tank levels
  • Speed over ground and through water
  • Propulsion power and RPM
  • Wind and depth

The typical installation includes an interface to integrated bridge and automation systems as well as devices such as speed log, weather station, tank sounding system, GPS, etc.

Technical Highlights

  • Runs on Eniram Platform
  • User-interface is accessible through Eniram’s kiosk PC, web browser and tablets
  • Accessible via any computer connected to the same network
  • Supported by any modern web browser

Frequently Asked Questions

Q: What is the difference between static and dynamic trimming?

A: In nutshell, a dynamic trim takes into consideration three factors that static trim systems based on CFD modeling cannot:

Optimum trimming in Dynamic Conditions

1Hull Deflection depends on how the vessel has been loaded as well as the temperature, and influences the real position of bow and stern.
2Sea conditions can vary, increasing the risk of exposing the bulb, propeller or rudder.
3Dynamic forces affect the vessel attitude after departure, varying based on the loading condition (ballast/laden) and environment.

Q: What is the accuracy of your attitude sensors?

A: Our sensors provide the measurement accuracy of 0.01 degrees in both longitudinal and transverse direction. On a vessel with length of 300m, this means about 5cm precision in trim measurement. We install 2-3 sensors to observe the deflection of the hull (sagging and hogging) as this can easily offset the trim measurement by 50cm, if not taken into account.

Q: How is trim measured?

A: By installing 2-3 high-accuracy Eniram attitude sensors, we are able to capture the full-range attitude of the vessel. This sensor network gives the capability to measure the TRUE trim of the vessel by taking into consideration forces such as deflection and speed-induced dynamic trim.
