GreenSteam, a company specializing in energy saving solutions for commercial vessels, has announced that after testing and comparing different solutions for dynamic trim optimization.

DFDS has chosen to install GreenSteam fuel saving solutions on 20 more vessels.

The vessels will be supplied with the onboard decision support solution, GreenSteam Optimizer that provides dynamic trim optimization. DFDS will also use the GreenSteam Manager solution for performance monitoring of these vessels.

GreenSteam develops what it calls advanced fuel saving systems that reduce a ship’s fuel consumption by on average 4 to 5 per cent. The system continuously collects a multitude of sensor readings at a much higher frequency and quality than normally used.

The relations between the vessel’s speed and energy requirements, and the ever changing internal and external conditions – like load, fuel flow, waves, wind and water depth – are analyzed with a specially developed mathematical model software. The trim and draft of the vessel are constantly optimized to give minimal propulsion resistance at all times.

The system guides the crew in real time through a touch screen monitor on the bridge.

The GreenSteam Optimizer is designed to react dynamically to changes in the ship’s condition and environment.  Additionally, the vessel’s and each mariner’s performance can be monitored remotely from shore by the fleet operator via the online browser-based tool GreenSteam Manager.

DFDS is an integrated shipping and logistics company in northern Europe with a network of 25 routes and 50 passenger and freight ships in the Baltic Sea, the North Sea and the English Channel, with the logistics division providing transport solutions in most of Europe.
