China-Russia Advance Plans for Arc7 Ice-Class Container Vessels

China's NewNew Shipping Line and Russia's state nuclear corporation Rosatom are progressing with plans to build five large ice-class container vessels, according to gCaptain. The initiative aims to enable year-round commercial shipping on the Northern Sea Route (NSR).

Rosatom Arctic representative Vladimir Panov described the planned Arc7 vessels as potentially "revolutionary" for Arctic shipping at the Eastern Economic Forum. The companies are in an advanced stage of project development. The ships have been designed by Russia's United Shipbuilding Corp.

Vessel Specifications and Capabilities

The planned Arc7 container ships would carry over 4,800 twenty-foot equivalent units (TEU), making them the largest container vessels specifically designed for the Arctic. Each 255-meter vessel would have a 35-meter beam and a 46-megawatt diesel-electric power plant, featuring two 15-MW electric propulsion motors driving fixed-pitch propellers.

These ships would be capable of independently breaking through level first-year ice up to 1.7 meters thick. Their 35-meter beam is designed to match the width of channels cut by Russia's Project 22220 nuclear icebreakers, allowing them to operate within the existing icebreaker escort system when independent navigation is not possible.

Project Timeline and Current Operations

The development of a dedicated Arctic container fleet has been a two-year effort by Rosatom and NewNew Shipping. The joint venture, Northern Sea Route Shipping Line, was established in China in late 2024. By June 2025, the partners were reportedly selecting a shipyard and considering government support for the construction of up to five Arc7 vessels, with a target for the first ship to be in service by 2027.

While the Arc7 ships are still under development and construction has not yet commenced, NewNew Shipping Line is expanding its Arctic capacity with a separate fleet of six 4,800-TEU vessels. Four of these are scheduled to enter service in October 2026 on a dedicated China-St. Petersburg route, with two more expected by June 2027. These vessels are described as ice-class, with one Chinese maritime report identifying them as Arc3 vessels, though precise specifications are not confirmed.

In August, NewNew Shipping Line's 29,000-deadweight-ton *Xin Xin Hai 1* became the first Chinese container ship to reach Murmansk via the NSR, transporting approximately 500 containers of automotive components from China. The expanded fleet is intended to support two NSR voyages per month, carrying cargo for Chinese automakers in St. Petersburg, Moscow, and Russia's Kaliningrad region. NewNew Shipping Line has set a target to move 1.2 million tonnes of cargo through the Arctic during the 2027 summer navigation season. The purpose-built Arc7 ships aim to extend the navigation season into the autumn and winter months, though attracting sufficient cargo volume for expanded operations could present a challenge.
