Bohai Ferry achieves 12% bunker fuel with fuel propulsion automation system

14 Sep 2020

Chinese RoPax operator Bohai Ferry and Norway’s Color Line have on Thursday (10 September) confirmed that fuel savings achieved through the use of Lean Marine’s FuelOpt™ propulsion automation system have exceeded their respective expectations.

As one of the more public-facing sectors of the industry, pressure to reduce the environmental impact of passenger shipping is mounting from both increasingly environmentally conscious customers and international regulations to reduce greenhouse gas (GHG) emissions from shipping, it said. 

In the past few years, Lean Marine said it has observed increased demand for FuelOpt™ from the RoPax sector: by September 2020, FuelOpt™ had been contracted for over 25 RoPax vessels.

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 delivers, it said. 

In 2019, Chinese RoPax operator Bohai Ferry installed FuelOpt™ on the vessel Bohai Baozhu to improve the operational efficiency of their fleet. 

From that first installation of FuelOpt™ onboard Bohai Baozhu in 2019, Bohai Ferry has confirmed in excess of 12% average fuel savings achieved over a period of more than one year.

“The FuelOpt™ system is always in satisfactory condition. We are convinced that Lean Marine is a trustworthy and cooperative partner, and its products should be worth using in more companies,” noted a Bohai Ferry representative.

In 2020, FuelOpt™ was installed on the two largest RoPax vessels in the world: Color Line’s Color Fantasy and Color Magic. Following full summer operations, Color Line had the lowest weekly consumption ever on Color Magic.

“We are very happy with our collaboration with Lean Marine. FuelOpt™ is now installed on board Color Fantasy and Color Magic, the two largest RoPax vessels in the world,” said Karl Wisløff, Superintendent at Color Line. 

FuelOpt™ achieves real-time fuel savings by controlling vessel propulsion and making sure that propulsive power is optimized automatically based on the set commands on power, speed, fuel consumption or a combination thereof, explained Lean Marine. 

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.

For vessels 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 added it also offers the smart performance management and reporting software Fleet Analytics™ which turns vessel data into knowledge, empowering organizations to be ‘lean’ and take fact-based decisions for more efficient vessel operations. 

Having a better understanding of a fleet’s performance enables ship owners and operators to learn from previous voyages and improve the next, hence reducing operating costs and emissions. The use of Fleet Analytics™ can unlock additional indirect fuel savings and emission reductions of up to 10%, it said. 

With FuelOpt™ in operation, up to 15% direct fuel savings and emission reductions are possible depending on the type of propulsion, trade and existing system settings for the vessel, added Lean Marine. 

The company notes that the fuel savings reported by Color Line and Bohai Ferry vessels confirm this and welcomes the opportunity for its technology to reduce the fuel consumption and emissions across the global shipping fleet.
