RoPax operators Color Line and Bohai Ferry have both confirmed that fuel savings achieved through the use of Lean Marine’s patented FuelOpt propulsion automation system have exceeded expectations.
In the past few years, Swedish marine propulsion experts, Lean Marine have seen increased demand for FuelOpt from the ropax sector.
Companies, including Stena Line, Color Line, Bohai Ferry and Viking Line have invested in the technology, due to the tangible fuel savings and CO2 emission reductions that the technology is claimed to deliver.
By this month, FuelOpt had been contracted for over 25 ropaxes.
FuelOpt has been designed to achieve real-time fuel savings by controlling a vessel’s propulsion and ensuring that propulsive power is optimised automatically based on the set commands on power, speed, fuel consumption or a combination of all three.
This removes costly variations in speed and power caused by human operational factors, allowing the vessel to achieve optimal fuel consumption at every given point throughout a voyage, Lean Marine said.
For vessels fitted with controllable pitch propellers, FuelOpt acts as a dynamic tuning system for the propulsion machinery to assure that the engine and propeller operate at optimal conditions.
In addition to FuelOpt, Lean Marine also offers the smart performance management and reporting software the patented Fleet Analytics, which turns vessel data into knowledge, empowering systems to be ‘lean’ and take fact-based decisions for more efficient vessel operations.
Through its automatic environmental and voyage reports, Fleet Analytics is claimed to help reduce the reporting workload on board and ashore.
Its performance management features, with aggregated fleet views and status information, allow onshore personnel to gain insight about the operational performance at vessel and at fleet level.
Fleet Analytics can lead to additional indirect fuel savings and emission reductions of up to 10%, Lean Marine claimed.
