Our first six "mixed" rollers can carry 6 aircraft simultaneously.

According to information from IT House on 6 June, today, a rolling ship constructed to transport aircraft parts was successfully brought down at the Wuchang shipyard of the China Boat Group.

The ship is the master of a new generation of low-emission roller-ships, created for the European aircraft manufacturer Airbus, named “Spirit of Toulouse” in Toulouse, France, and two other vessels in the series, entitled “Spirit of Mobile” and “Spirit of Mirabel”, respectively, are currently under construction.

Upon delivery, the ship will mainly serve the airborne air supply chain, carrying aircraft parts, such as body, wings and tails, across the Atlantic between the production base in Saint-Nazelle, France, and the single-channel aircraft master line in Mobil, Alabama, United States.

The IT house was officially informed that the ship was about 169 metres in length and 23.32 metres in width, designed to eat about 5.7 metres in water and speed 14 knots in service. The cargo compartment on board is designed to be more than 2,600 square metres, larger than six basketball courts, with a net altitude of 8 metres, near the third floor, and an overall cargo hold of over 20,000 cubic metres, equivalent to nine standard swimming pools.

In order to meet the special transport requirements of aircraft components, the luminum unit is equipped with a full roller system, including heavy lifts and large cargo elevators, which will enable the rapid and safe roller and load of large-sized components.

A new ship can carry six single-channel aircraft components at a time -- wings, fuselages, engine hangers, levels and props. Straight-tail wings, which are nearly two times the capacity of the old roller ship, can also carry an additional approximately 70 standard containers. The cargo compartment is also equipped with a robust environmental control system that allows real-time control of temperature, humidity and salinity to meet strict requirements in the transport of aircraft components.

In terms of green power, the ship installed six cylinders of chimneys in the hulls, hulls and hulls, which are currently the largest roller of wind-carrying auxiliary propulsion systems worldwide. These sails are 6 metres in diameter and 35 metres in height and are internally equipped with rotors, which are made of light materials at the aviation level.

The working method is based on the Magnus effect: high-speed rotation through electric-driven wind cylinders, which results in low pressure from currents on both sides, thus creating a push vertically in the direction of the current to support the ship's forward. Ideally, this could reduce mainframe power consumption by 15 to 20 per cent and theoretically reduce carbon emissions by about 1,000 tons per year.

At the same time, the ship uses methanol and diesel dual-fuel technology, equipped with two methanol double-fuel hosts and auxiliaries that allow for flexible switching between methanol and traditional fuels.

Methanol combustion results in sulphur-free emissions, nitrogen oxide emissions are more than 80 per cent lower than traditional fuels and carbon emissions are about 25 per cent lower, meeting the latest emission standards required by the International Maritime Organization. A “mixing” system consisting of 6 cylinder sails and methanol double-fuel hosts can reduce aggregate carbon emissions by more than 17 per cent compared to previous-generation ships. In addition, IT House noted that the ship also carried a route optimization software, which could be used to select the routes most conducive to wind use, based on real-time windfield and sea state dynamics, and to enhance response capacity through AI-driven control systems.

The boat was also brought in in a different way, using an oscillation to carry it down, as if it were in an elevator. This approach, which does not require the construction of large marinas, is less demanding of the site and more rapid in revolving than the need for large marinas.

When the ship is released, the functional test of the engine, propeller, electrical system, etc., will be completed at the docks and is scheduled for formal delivery in November 2026. This series of ships is currently on three orders, and with the increasing demand for energy-saving emission reductions in the global shipping industry, it is expected that there will be an increasing number of future customized environmental vessel orders.
