Fuel Saving Systems

Over the last few decades, rapidly growing energy demand and climate change have evolved as issues of global concern. In this backdrop, in today’s oil based world, a broad consensus has emerged in business, scientific and political communities to reduce Greenhouse Gas (GHG) emissions. Given that the ships are the most important means to transport goods and as a result, one of the most important fossil fuel consumers, the ships are the major contributor to GHG emissions, and therefore a shift towards minimizing the fuel consumption has become the “norm”.

For shipping companies, the cost of fossil fuel is the most important cost factor for their operation. Therefore the reduction of the fuel consumption and implicitly the profitability increase are permanent goals for these companies.

The Fuel Saving System is much more than a fuel monitoring system. This system is able to provide to the crew all the necessary information, in real time, to minimize the fuel consumption, and maximize ship’s profitability.

Additionally, the system is designed to achieve all objectives aimed by SEEMP and MARPOL Annex VI: NOX, SOX and EEOI. By using a series of instruments, high-tech components and a real-time optimization algorithm, the system implements also functions which help the crew to increase the ship operational reliability.


Distinguishing characteristics of the system include the following:

  • Guaranteed fuel savings by continuous calculation of the optimal speed (from minimum 10% to the maximum possible)
  • Ship’s profit maximization
  • Accurate fuel bunkering to avoid measuring errors
  • Eliminates human factor in fuel consumption losses
  • Helps to identify and eliminate ship-specific fuel losses
  • Helps to achieve load balance between main engines
  • Trim optimization
  • Fuel savings for ships are achieved in a safe, efficient and environmentally sound manner
  • Monitoring of NOX, SOX and CO2 emissions as per MARPOL Annex VI and EEOI (as per MEPC 1 /circ. 684);
  • Measurement and trending of fuel losses
  • Customization
  • Used for any type of diesel and for any type of fuel
  • Used for any type of ship provided with any type of propellers (CPP, FPP, Voith Schneider)
  • Optimization in any weather conditions (wind, tides, currents, ice, etc.)
  • Measures the engines’ kW load
  • No additional cost after the installation
  • Ship-based, not depending on the shore support
  • Competitive advantage in a highly competitive market
  • Prevents fuel theft
  • Reliable configuration
  • Accuracy in fuel management (from bunkering to consumption)
  • Initial cost recovery from fuel savings within 6 months
  • Ease of installation on ships under construction
  • A user friendly and well organized set of assembly and operating procedures that guarantee proper operation “the first time”.
  • Non-intrusive system (can be installed during operation of the ship
  • Competitive advantage in a highly competitive market
  • No need for periodic tuning
  • Basically maintenance free
  • Internet access
  • Automatic Daily Reporting customized per customer and ship needs

The Pronova Fuel Saving System was tested or permanently installed on a variety of ships (tug-barge systems, ferry-boats, cruise liners, container ships, bulk carriers, etc.) and the fuel saving was at least 10% achieved only by the ship speed optimization. Other optimization functions will add more fuel savings.

This screen is used to maximize the profit of the ship by establishing the most profitable speed of the ship.

The optimal speed is the speed corresponding to the minimum fuel consumption. This screen guides the ship operator to establish the optimal ship speed range and the optimal speed value.
