World's largest intelligent container ship sets sail
The delivery of the nation's first and the world's largest
intelligent container ship powered entirely by electricity
marks the transition toward a greener and more
intelligent future by China's shipping industry, experts
said.
Following the successful completion of various tests, the
vessel, named Ning Yuan Dian Kun, was delivered in
Ningbo, Zhejiang province, on Wednesday.
"From the initial project approval to the final delivery, the
vessel showcased the full life-cycle development of zero
carbon ships, characterized by pure electric propulsion,
autonomous navigation and high operational efficiency,
achieved by China's shipping industry," said Ma
Hongmeng, a senior engineer at Shanghai Merchant
Ship Design and Research Institute and the person in
charge of the intelligent container ship.
According to Ma, the ship is proof that China's coastal
container transportation segment is entering a new era
marked by zero-emissions, intelligent operations and high
efficiency, a prerequisite for achieving carbon neutrality
and shipping energy transformation.
With a capacity of over 740 twenty-foot equivalent units,
the vessel was independently developed and designed
by SDARI. Its electric propulsion system was provided by
Shanghai Marine Equipment Research Institute. Both
companies are subsidiaries of China State Shipbuilding
Corp.
"Independently developed by SMERI, the innovative
electric propulsion system has undergone maritime
navigation tests, which fully proved its reliability,
superiority and adaptability," said Wu Guodong, a senior
engineer at the institute.
He added that with all performance indicators meeting
expectations, the technological breakthrough from design
to application highlighted China's leading position in pure
electric ship power system integration worldwide, and laid
a solid foundation for the transformation of China's
shipping industry to a greener and carbon neutral one.
With a length of 127.8 meters and a width of 21.6 meters,
the ship has been tailor-made for Ningbo Ocean Shipping
Co and will run on the coastal shipping route between
Ningbo and Jiaxing in Zhejiang province.
A senior official from the Ningbo Maritime Safety
Administration said that due to the distinctive features of
new-generation intelligent vessels, a dedicated service
team has been established to provide comprehensive
support. The team will conduct continuous tracking and
precise assessments throughout the entire process —
from design and construction to navigation — ensuring a
thorough grasp of the vessels' technical characteristics
and effective control of operational risks.
The vessel is equipped with 10 container-shaped power
units with a total power supply capacity of about 19,600
kilowatt-hours.
"This allows the ship to achieve zero-emission and
zero-noise green operation throughout the entire voyage,
while perfectly adapting to the practical operational needs
of coastal container transportation," Ma said.
Wang Ting, captain of Ning Yuan Dian Kun, also
confirmed this view. "Compared with traditional
fuel-powered vessels, the most noticeable change in a
fully electric seagoing ship is the lack of noise. In the
past, the engine room would be filled by the roar of the
main engine, whereas voyages nowadays are almost
silent. This creates a more relaxed working environment
and allows crew members to concentrate better on
operations — a significant improvement brought about by
green energy," he said.
He added that in terms of power response, the torque
output of electric propulsion motors is linear and
instantaneous. Acceleration and deceleration are smooth
and highly responsive, with virtually no delay, making
operations more straightforward. However, this also
places new demands on operators — they must learn to
manage energy efficiently, closely monitor power
consumption, and plan vessel speed in a more rational
manner.
The ship has also adopted two permanent magnet
synchronous propulsion motors, capable of cutting carbon emissions by 1,462 tons per year, and completely
eliminating emissions of sulfur oxides, nitrogen oxides
and fine particles.
"In this way, we manage to achieve zero pollution
throughout the entire process of transportation, ranging
from navigation and berthing to loading and unloading,"
Ma from SDARI said.
Currently, Ningbo Ocean Shipping Co operates 32 green
and energy-efficient vessels, accounting for 57 percent of
its self-owned fleet, marking the initial formation of a
sizable green fleet.
Chen Xiaofeng, chairman of the company, said: "We
hope to achieve breakthroughs in key areas through
Ning Yuan Dian Kun. We aim to build the country's first
demonstration model of a fully electric seagoing vessel,
promoting the expansion of pure electric technology from
inland waterways to maritime transport. We seek to
establish a complete, replicable technical and operational
system for 'zero-carbon transportation'."
