Lean Marine to equip two Neste tankers with FuelOpt™ smart propulsion automation technology Swedish propulsion optimization and ship performance management experts, Lean Marine have signed a contract with the Finnish refiner Neste to install the FuelOpt™ ‘on top’ propulsion automation system onboard two newbuilding aframax crude oil tankers. Since introducing FuelOpt™ to the market in 2013, Lean Marine has transformed vessel propulsion control, with FuelOpt™ enabling direct fuel savings across hundreds of vessels in the global fleet to-date via the automated and optimized control of vessel speed and fuel consumption. Once activated from an intuitive panel on the bridge, FuelOpt™ optimizes a vessel’s propulsion line in real-time based on the commands set for engine power, fuel consumption, speed, or a combination thereof. This enables the automated control of vessel speed and fuel consumption, allowing for the avoidance of potential fuel overconsumption in harsh sea conditions, such as high swells and winds.
