International Collaboration Develops Concept of 3,500 TEU Feeder Ship, Focusing on Safety and the Feasibility of Ammonia as Fuel to Decarbonize Maritime Transport.

The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) has revealed a conceptual design for a 3,500 TEU feeder container ship powered by ammonia. The initiative, developed with strategic partners, represents a significant advancement in the technical qualification of ammonia as a viable energy source for the future of shipping.

A Technological Leap for Shipping with Ammonia

The project was a collaboration between MMMCZCS and industry giants. Among the partners are the engine manufacturer Everllence, A.P. Møller-Maersk, the classification societies ABS and Lloyd’s Register, the Danish Maritime Authority, the Maritime and Port Authority of Singapore (MPA), engineering company Deltamarin, and Eltronic FuelTech.

The ship concept was built on pillars of safety and cargo capacity. It considers an early deployment, using 60-cylinder two-stroke engines that are already available. The design also anticipates a scenario where the ammonia supply infrastructure is not yet fully developed.

Design Focused on Safety and Efficiency

Safety was the central focus of the project. The overall goal was to create “a safe container feeder that integrates state-of-the-art ammonia fuel technology.” The design offers clear advantages to ensure safety.

The ship’s Type A storage tanks balance safety and space efficiency. The centralized refueling station provides flexibility for safe berthing and fuel transfer.

Additionally, the fuel preparation room (FPR) can be positioned near the engine room, which reduces risks and aids in the safe handling of ammonia. The ventilation system of the unit was also designed to direct potential leaks away from crew-accessed areas.

The Potential on the Path to Decarbonization

Ammonia is a highly attractive option for maritime transport. It has the potential for a 97% reduction in greenhouse gas (GHG) emissions if produced from renewable energy (e-ammonia).

This is not the first project of its kind for MMMCZCS. In July 2023, the entity and its partner Foreship received approval for a 15,000 TEU box ship also powered by ammonia, as part of a feasibility study in Singapore.

The Reality of Ammonia Use

Despite its potential, ammonia presents considerable challenges. Its toxicity, flammability, and corrosiveness are serious issues. The infrastructure for its use is still underdeveloped and the technology immature.

The lack of prescriptive regulations for ammonia-powered ships has also been a factor that required the exploration of alternative design processes and in-depth risk assessments during the creation of the concept.

The Need for Capacity Building for the Ammonia Era

The transition to ammonia heavily depends on the workforce. An MMMCZCS report from October 2024 noted that most seafarers are “willing” to work with this clean fuel.

However, the center highlighted in February 2025 that a significant workforce reshaping is necessary to prepare professionals for the safe handling and use of ammonia. According to MMMCZCS and Lloyd’s Register, at least 800,000 workers will need to undergo specialized training programs to qualify for handling this sustainable fuel.

The Need for Capacity Building for the Ammonia Era

While an average building in London or New York takes three years to be completed, in China a 26-story tower went up in five days with about 100 workers, and the global modular construction market already moves US$ 95 billion per year.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Australia installs giant concrete structures on the seabed 800 meters from the shore to create an ocean intake for desalination that will draw in saltwater and produce 30 million liters of drinking water per day.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

It seems like something out of a movie, but it’s real: how technology uses invisible sound waves to extinguish small fires without water, without chemicals, and without destroying household furniture.

Chinese boats accelerate the collapse of fishing in Senegal, cause an annual loss of US$ 300 million, affect 1.3 million people, and help transform West Africa into the epicenter of 40% of the planet’s illegal trawling.

Super airplane Phantom 3500 advances towards its first flight, promising 60% lower fuel consumption, a windowless cabin, operation above 51,000 feet, technology validated by DARPA, and a billion-dollar order of 300 jets before certification.

With an updated oil-bathed belt, the 2026 Chevrolet Onix and Onix Plus arrive with discounts of up to R$ 23,000, fuel consumption of up to 19.7 km/l, a range of 866 km, a 115 hp turbo engine, and a 5-year warranty.

Switzerland dug a hole the size of two football fields to install the most powerful underground battery on the planet, capable of releasing 1.2 GW in milliseconds, storing 2.1 GWh, and costing up to 5 billion Swiss francs.
