Finnish company Neste has signed a deal with Swedish ship performance tech firm Lean Marine to install the FuelOpt propulsion management system on board two newbuild Aframax crude oil tankers, to minimise fuel consumption and emissions after delivery.
Once activated from a panel on the bridge, FuelOpt monitors a vessel’s propulsion line in real-time based on set parameters for engine power, fuel consumption, speed, or a combination thereof, and can automatically adjust vessel speed and fuel consumption to optimise performance.
The system’s adaptive algorithms take varying conditions, such as weather, hull resistance and currents, engine load, and shaft power into account in its calculations, and can act as a dynamic tuning system on vessels with a controllable pitch propeller to ensure that the engine and propeller operate at optimal conditions.
This is achieved by controlling the propeller’s pitch and RPM separately to produce the highest amount of propeller thrust with the least amount of power.
“At Neste, our purpose is to create a healthier planet for our children. To achieve this, our ambition on decreasing climate emissions, innovation and collaboration plays an important role,” said Risto-Juhani Kariranta, Shipping Performance Manager at Neste Corporation.
“From the ship performance perspective, Neste has been evaluating clean technologies for optimised vessel performance. We believe that Lean Marine’s FuelOpt system will empower our newbuilding tankers with fuel savings and emissions reductions from day one.”
