Swedish propulsion optimization expert, Lean Marine is proud to announce that their FuelOpt™ reached the 200-vessel milestone in late March 2021. Since commercialization, automated propulsion optimization technology FuelOpt™ has proven its efficiency, gaining a wide-ranging reputation for real-time fuel savings, optimized control of speed and consumption, and emission reductions from crew and onshore personnel.

Mikael Laurin, CEO at Lean Marine, says:

“We are celebrating the 200th vessel contract for our FuelOpt™ system. This a clear confirmation of FuelOpt™’s efficiency in saving fuel and reducing emissions. We are proud to have the trust of so many companies and crews when it comes to helping them achieve their green shipping goals while boosting their bottom line. We look forward to supporting even more vessels in the near future.”

Since introducing FuelOpt™ to the market in 2013, Lean Marine has revolutionized vessel propulsion control, and become synonymous with direct and real-time fuel savings in the marine industry.

A technology focusing precisely on enhanced vessel efficiency

FuelOpt™ focuses on the parameters that matter the most for enhanced vessel efficiency: speed, fuel consumption, engine power or a combination thereof. It provides the crew full control of these parameters via an intuitive panel on the bridge.

Once activated, the system dynamically controls vessel propulsion based on the commands set, adapting the propulsive power to the changing environmental conditions. In this way, steady and predictable shaft power can be achieved, removing costly variations in speed and power caused by human operational factors and achieving real-time fuel savings and emissions reductions.

On vessels with a controllable pitch propeller, FuelOpt™ acts as a dynamic tuning system for propulsion machinery. The system regulates the propeller’s pitch and RPM separately to operate the engine and propeller at optimal conditions. In this way, the system produces the maximum amount of propeller thrust with the minimum amount of power, optimizing energy use.

Preparing for the future: innovations and regulations

In late 2020, Lean Marine announced their participation in the Via Kaizen project, where FuelOpt™ has a key role. The project aims to accelerate the technological development, realization, and adoption of AI-powered ship operation support technology by ship crew and management. In this project, the FuelOpt™ system will create a direct interface between the crew, machinery, and the AI-based solution, empowering them to work together and execute the voyage.

FuelOpt™ is essential as, on these AI-powered voyages, it automatically and directly optimizes the propulsion line based on commands set by the captain and/or sent by an AI-powered voyage optimization solution.

Jonas Persson, Sales Director at Lean Marine says:

“With 200 vessels of various types and sizes empowered by FuelOpt™, we have proven the benefits of the FuelOpt™ system on enhanced ship operations across the industry. FuelOpt™ does not only support shipowners and operators in short-term decarbonization goals but also assists them in future-proofing their fleet regardless of their transition strategy. FuelOpt™ is a solid base to support any strategy; for instance, energy transition towards alternative fuels, wind-assisted propulsion systems, AI-powered ship operations, and others.”

As recently announced, the FuelOpt™ system is also compliant with the shaft power limitation requirements as suggested in the current Energy Efficiency Existing Ship Index (EEXI) framework. By enabling ship operators to set an upper limit to shaft power output without any modification to existing machinery, it aligns operations with EEXI requirements. Additionally, the system can be overridden in an emergency, thereby enabling access to the engine’s full power.
