First movers take risks. Real change needs operations.

Not a prototype, but proof. The fuel transition becomes real only when innovation is ready to operate safely, efficiently, and at sea.

Maya Cosulich is not only a new vessel. She is proof that the transition to alternative marine fuels becomes real only when technology, regulation, and operational reliability meet at sea.

In 2025, the launch of Maya Cosulich marked a decisive milestone for the Group and for the marine fuel industry.

As the world’s first methanol-powered IMO II chemical bunker tanker, she introduces a new standard for the safe and efficient delivery of alternative marine fuels in one of the world’s most strategic bunkering hubs.

Designed with diesel-electric propulsion, onboard battery storage, mass flow meters, and fully integrated methanol handling systems, Maya Cosulich was built to operate in full compliance with Singapore’s methanol bunkering standards.

But her value goes beyond technology.

She is the result of a shared path involving the Group, its chartering partner, port authorities, technical teams, and shipyard partners. 
A project where vision became engineering, and engineering became service.

For Fratelli Cosulich, Maya is more than a first-of-its-kind achievement.

She shows that standing over waves means being ready before the market fully changes. Not by waiting for the transition, but by making it operational.
