MOL will lead the shipping industries in terms of environmental protection by differentiating by adopting advanced environmentally-friendly technologies to one of the world largest class containerships, with capacities of 20,000 TEU.
From the energy efficiency improvement by becoming larger and the technologies to reduce environment load, these vessels can reduce CO2 emissions per container moved by about 50% compared to 8,000 TEU containerships, which are the mainstream size today.

Inverter control is adopted for the air conditioning system in the living areas, seawater cooling pump, and engine room ventilation fan. Improved control of the large-capacity fan motor rpms minimizes electric power consumption and reduces fuel consumption.
Exhaust gas economizers are installed on two of four diesel generators. They recover exhaust gas energy from the generator engines, contributing to higher fuel efficiency.
Optimize the angle of the propeller blade tips increases propeller efficiency by about 1%.
A rectifier Fin is mounted on the underwater portion of the hull in front of the propeller. This is expected to generate a fuel-saving effect of 1.5-2% by optimizing the flow of the water coming into the propellers.
To ensure vortex energy recovery of the propeller slipstream, adopted a twisted leading edge and set a bulb with round-shaped center front, in front of the rudder, In addition, the hanging-type rudder improves maneuverability and reduces damage to the rudder caused by propeller cavitation erosion.
MOL is carrying out feasibility study to allow the ship to run on LNG fuel as a measure to comply with stricter environmental regulations limiting SOx emissions.
Other than allowing the option of using LNG as a fuel, MOL is carrying out feasibility study to allow retrofitting of an SOx scrubber, providing more flexibility in coping with the fuel supply situation in the coming years.
Low-load tuning (LLT), optimizes performance and fuel efficiency in low load ranges.
This equipment optimizes the maximum pressure in a cylinder's combustion chamber by monitoring pressure in each engine cylinder and automatically adjusting the fuel injection timing. This auto-tuning optimizes fuel combustion and improves fuel efficiency.
Design refinements in the bow and stern of the hull, and the bulbous bow are expected to realize a 4.5% boost in fuel efficiency.
Special low-friction paint on the underwater portion of the hull has the potential to significantly reduce drag and improve fuel efficiency.
The system will meet the requirements of the Ballast Water Management Convention.
"Eco Sailing" is MOL's term for promoting energy saving by fully grasping the energy flow of the vessel, limiting energy loss to make the most effective use of energy, thus saving fuel and reducing emissions. Specifically, we take measures such as: (1)put slow steaming into practice in an appropriate manner, (2)pay close attention to forecasts of weather and ocean conditions and maintain optimal trim, (3)select the optimal route, (4)optimize operation and maintenance of machinery and equipment.
Optimal Trim Operation
MOL pays attention to propulsion resistance by changes in trim and verifies the minimum resistance trim in vessel operation by water tank tests, helping to ensure energy-saving operation.
In advance of the Ship Recycling Convention coming into effect, MOL acquired ship class notation LR-ECO (IHM) by creating and maintaining the inventory lists.
