SEMS

– energy optimization on the Læsø ferry

Xtel has been part of the SEMS project, which has developed an information system for energy optimization on ferries.

Automated energy consumption monitoring system

SEMS (Ship Energy Monitoring System) was initiated on the basis of the growing demand for energy optimization in the marine industry.

At the Læsø ferry, the most energy-intensive systems were to be monitored (e.g. heat, ventilation and air conditioning). At the same time, there was a wish for optimizing electricity production onboard the ship. 

Xtel developed an information system that measure, register and display energy consumption for each system. Using intelligent calculations, the system visualizes and informs on energy efficiency.

The system was built via HTML5 and could therefore be executed on different platforms.
Today, it is used to render visible and processes poor consumer behavior, thereby changing the attitude towards energy waste among the employees at the Læsø ferry.

The goal is to turn data into information, and information into insigt

Technical specification

Graphic touch displays are mounted in traversed areas that show real-time values, energy efficiency mark (A-G) and historical data, e.g. consumption on each trip, consumption on the five previous trips and savings in fuel.

The installed PC in the engine room collects consumption data and calculates consumption patterns, which present a more detailed overview of the consumption of the entire ship and all its zones, via a single screen display.

You can also monitor energy consumption from shore, as you can access the systems via a wireless connection. This makes it possible to delve deeper into the ferry’s previous data and analyze where to use energy optimizations.
