Improving Transport Efficiency and Increasing Fuel Efficiency


Containership MOL Triumph

The world's first largest over 20,000 TEU-class (capacity: 20,170 TEUs) was launched on the Asia/North Europe routes, and is operated by MOL.

The vessel is equipped with a range of highly advanced energy-saving technologies including low friction underwater paint, a high efficiency propeller and rudder, a Savor Stator stream fin on the hull body, and an optimized fine hull form which together can further reduce fuel consumption and CO2 emissions per container moved by about 25-30% when compared to 14,000 TEU-class containerships.

Additionally, the vessel has been designed with a retrofit option to convert to LNG fuel in view of the implementation of the new regulation in the future.

The MOL Triumph is equipped with the Hull Stress Monitoring System, which constantly monitors the status of the hull while the vessel is underway, and a ship operation monitoring system using high-speed data transmission technology, in addition to environmental technology. Swift transmission of information between ship and shore also contributes to safer vessel operation.

① Auxiliary Equipment

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.

② Diesel Generators

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.

③ High-efficient Propellers

Optimize the angle of the propeller blade tips increases propeller efficiency by about 1%.

④ Fuel-saving Device Attached to the Hull(SAVER STATOR)

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.

⑤ Full Spade Twisted Rudder (with Rudder Bulb)

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.

⑥ For Shifting to LNG Fuel

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.

⑦ Easy-to-Retrofit SOx Scrubber

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.

⑧ Low-load Tuning with Exhaust Gas Bypass (EGB)

Low-load tuning (LLT), optimizes performance and fuel efficiency in low load ranges.

⑨ PMI Auto Tuning

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.

⑩ Optimized hull form

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.

⑪ Low-friction Hull Paint

Special low-friction paint on the underwater portion of the hull has the potential to significantly reduce drag and improve fuel efficiency.

⑫ Ballast Water Treatment System

The system will meet the requirements of the Ballast Water Management Convention.
