Next steamer Online, this time S/S Storskär!

We are happy to announce commissioning of Blueflow on this old lady, built 1908 at Lindholmens varv in Gothenburg. We now measure and report fuel consumption of the diesel boilers, generated power from the auxiliary engine and shore power energy. The challenge with this installation was to not interfere with the classical interior of an old steam ship. All necessary equipment is “hidden” as far as possible not to disturb the feeling of being on an old steamer.


Our first steamship online:-)

Blueflow is now commissioned on the steamship Norrskär, operated by Waxholmsbolaget in the archipelago of Stockholm. This ship is built in 1910, and equipped with a steam engine from Eriksberg. The steam is generated from three diesel boilers and the fuel consumed is measured with a flow meter from Aquametro. Of course, fuel economy is not the priority of this installation. It is more about having all fuel consumption for the hole fleet available in a common report platform, and Norrskär now joins the rest of the fleet in Online 3.0.


The latest ship joining Blueflow is M/S Vaxö

She is equipped with three main engines from MTU where the fuel consumption is measured with flowmeters from Aquametro. Energy consumption from the two auxiliary engines and the shore power is collected from the existing information system onboard. Finally we mount a Badger flowmeter on the boiler. All information is now presented on-board and in our web platform Blueflow Online 3.0. The installation was carried out by Robin at El- och Marinteknik in Stockholm. Many thanks for good support!


Harbour City Ferries

We are happy to present a new product in the Blueflow portfolio – Blueflow Wallboard

Blueflow Wallboard gives the operator an overview of the fleet´s key performance indexes, and enables a quick analysis in one glance.

The wallboard is presented on a standard large screen TV and will fit perfectly in your company reception or in the office conference room.

Blueflow Wallboard gives a quick status overview of the fleet such as energy consumption, costs,  geographical locations on a map, speed, emission levels and more.
It is very well suited for monitoring energy and emission targets because the screen is intended to be placed in environments such as coffee rooms, hallways, receptions or other well-visited areas.

You decide what the wallboard should contain according to your needs and wishes.

We are right now in the middle of a project where we are rolling out Blueflow Energy Management on Trafikverket/Färjerederiet – STA Road Ferries across the country

In connection with each installation, all crews receive a solid training in energy management and the knowledge of using the Blueflow system in their daily work on lowering fuel and energy consumption.

The training carried out by Smart Eco Shipping is a vital part of Färjerederiet’s determination for a successful energy management project and thus also in their work for a sustainable environment throughout their fleet.

Energy management is the term given to activities associated with monitoring, analysing, controlling and saving energy

Reducing our CO2 emissions is one of today’s most pressing issues. Every organization can make some contribution to reducing its CO2 emissions. The fact that this can reduce costs also makes it attractive to do. An energy management system helps an organization work systematically on reducing its energy consumption.

Energy management takes careful planning, implementation and continuous evaluation to determine whether energy saving actions carried out through:

  • Company commitment
  • Understanding energy use
  • Planning and organisation
  • Implementation
  • Verification, monitoring and reporting
  • Iteration


A total of 26 installations will be carried out during a period of 18 months. This order confirms Blueflow´s position as a major supplier of Energy Management Systems for the marine market. This project runs in collaboration with our partner METS technology in Uddevalla.

ECO-driving taken to the next level!

With our newly launched function “Blueflow ECO-trip” the driver of the ship gets instant feedback of the ship´s fuel- and energy consumption. The graphical interface compares current trip with last trip on the same route, and different driving techniques are directly comparable. All historical routes are compared in a list, and average values are calculated and presented.

Saving fuel and energy is not magic. It is about hard work, training and motivation combined with a support system that actually enables follow-up of implemented measures. Doing this correctly, 10-20% of saved fuel is fully realistic targets.

If interested, please contact us and we will help you save fuel as well.

Blueflow Energy Management System™

The Blueflow Energy Management System helps you manage your vessels’ energy sources. It presents consumption and energy efficiency data on intuitive graphical user interfaces onboard your vessels. It collects and sends data to our cloud platform for secure storage and easy data analysis.

The system consists essentially of two parts:

Blueflow Online™ and Blueflow Onboard™.

Blueflow Online™ is our secure cloud platform that stores vessel data with a resolution of one second. Ultra-fast data processing enables almost unlimited possibilities to find complex relationships of the data on a vessel. These findings can be used to reduce energy consumption, make diagnostics, take comprehensive reports and increased knowledge of a vessel’s performance.

Blueflow Onboard™ integrates with various other onboard systems and flowmeters to monitor fuel and energy consumption and other parameters in real-time. Parameter data are sent to Blueflow Online™ for reporting, analysis and verification. Various displays can be installed for eco-driving and monitoring of energy consumers.

Blueflow MRV Solutions  – Ready for you – Easy to use

Shipping companies must now begin monitoring and reporting vessel greenhouse gas emissions for ships of more than 5,000 GT loading or unloading at European ports. Owners will need a monitoring plan for every ship, and will need to submit annually verified emissions reports to the European Union covering all voyages to/from/within Europe. Mandatory ship emissions monitoring will begin from 1 January 2018, but owners should have submitted monitoring plans by the end of August 2017.

Our MRV solution is based on many years experience and knowledge of energy measuring and reporting. Our state the art IT energy management platform, widely used and developed during many years fits the MRV regulation demands very well. Our MRV solution includes all MRV requirements such as monitoring plans, voyage emission reports and much more.
