A new solution for maritime energy efficiency optimization

Rising requirements for environmental protection pose a serious challenge to the shipping industry today, as do historically high fuel oil prices.

GreenSteam™ is a revolutionary new, patent pending energy saving system for ships that provides a significant reduction in fuel costs by adjusting the ship’s trim and speed so as to minimize propulsion resistance. GreenSteam™ is very simple to use, requires no major modification of the ship and gives a real boost to your environmental profile.

Behind GreenSteam™ is a team of dedicated, highly educated engineers and scientists who have spent years of research to combine common-sense principles with advanced engineering to create a practical, simple-to-use energy saving system.

A New Approach

GreenSteam™ is based on two fundamental facts. First, that the relations between the fuel efficiency of a ship and various conditions affecting that efficiency are complex. Second, that these conditions change dynamically with time.

Therefore, an approach is called for that does not ignore these facts, but rather exploits them. That is why GreenSteam™ starts by ‘going onboard’ to collect a multitude of sensor readings over a prolonged period of time, in order to form a picture of these dynamically changing conditions and changes in fuel efficiency.

When enough data has been collected, mathematical models are then built that uncover the knowledge that is contained in the data, although hidden to the naked eye. The relations between the ship’s speed and energy use and a range of internal and external factors are learned through the use of sophisticated, specially developed software that forms a core part of GreenSteam™.

Obtained from this is a system that is able to provide continuously updated advice on optimal settings of controls. GreenSteam™ is able to react dynamically to changes in the ship’s condition and environment, thereby making it possible to always operate with the greatest possible fuel efficiency. Every second, the current conditions are measured and input to the operational GreenSteam™ system that immediately finds a new setting for e.g. trim and propeller RPM that is optimal in the current situation. This advice is continuously supplied to the user interface on the bridge.

The collected data may also reveal important, previously unseen knowledge about the energy dynamics of the vessel. Detailed fuel and CO2 reports can also be generated for the ship. GreenSteam™ provides a high-quality, high-frequency database that contains a wealth of information about the operational history of the ship.

Reduced Emissions – and Costs

We want to aid in your efforts to protect the environment, but we also want you to make a profit at the same time. GreenSteam™ works by reducing fuel consumption. This means that with GreenSteam™, reductions in costs and reductions in harmful emissions, rather than being opposing forces, are two sides of the same coin.

In previous instalments of GreenSteam™, savings on the order of 5 percent have been demonstrated.

Partnership

We are fully aware that many shipping companies today are putting very serious efforts into reducing the environmental impact of their activities. That is why we always view our customers as partners, in the best sense of the word. We work very closely with our customers – some of whom are among the world’s leading shipping companies - in order to draw upon their vast experience in the shipping domain, as well as to ensure that the delivered products meet expectations. We are highly flexible with regard to special wishes and concerns that you may have for a particular implementation of GreenSteam™.

We invite you to join forces with us today for a greener and more profitable future!
