One vessel proves an idea. A fleet builds the future.

From one vessel to a fleet: when future fuel readiness becomes an industrial choice, built to serve today’s market and prepare tomorrow’s demand. 

Innovation becomes meaningful when it can be repeated.

For years, the marine energy industry has discussed alternative fuels, new regulations, and the transition towards lower-emission operations. Yet real change happens only when ideas move beyond pilots and become part of everyday infrastructure.

In 2025, Fratelli Cosulich took an important step in that direction.

Anna Cosulich entered service, Lucia Cosulich was launched, Carlotta Cosulich moved into construction, and Natalia Cosulich completed the four-vessel programme that will shape the next generation of the Group’s bunker fleet.

Built as methanol-ready IMO II bunker tankers, these sister vessels were designed from the outset to support both current and emerging fuel requirements. Their purpose is not limited to future methanol operations: it is to provide safe, flexible and reliable bunkering solutions while the market continues to evolve.

Their design reflects this dual role. Advanced cargo tank coatings, dedicated systems for future fuel integration, and high operational standards make them suitable for today’s activity and ready for tomorrow’s demand.

Together, these vessels represent a long-term commitment to fleet renewal and a practical approach to the energy transition.

Standing over waves means preparing for change before it becomes unavoidable.

It means turning vision into a fleet.
