BUSINESS SECTOR

Energy & Green Solutions

ONEX Shipyards & Technologies Group is developing a strategic energy and green solutions platform focused on maritime decarbonization, offshore energy infrastructure, sustainable industrial modernization and critical energy support systems. The Group’s environmental and energy positioning is grounded in its existing strengths: shipyards, heavy fabrication, offshore experience, digital systems, logistics and industrial execution. This gives ONEX the ability to support the green transition not only conceptually, but through real infrastructure, vessel programs and industrial operations.

Maritime Decarbonization

ONEX supports the transition toward cleaner shipping through green retrofit programs, scrubber installation, carbon capture integration, smart vessel upgrades, installation of Energy Saving Systems on vessels and alternative fuel readiness. Its innovation work includes transition pathways related to LNG, LPG, ammonia and methanol, supporting shipowners and operators as regulation, fuel systems and environmental requirements evolve.

Offshore Wind & Offshore Energy

ONEX is positioning its shipyards as a one-stop industrial platform for offshore wind platforms, offshore wind farm support systems and offshore support vessels. Its capabilities include shipbuilding, maintenance, heavy fabrication, logistics, supply-chain synergies and support for specialized vessels such as cable laying vessels, technical support vessels and anchor handling tug supply vessels.

This creates a natural expansion path from maritime industry into offshore renewable energy infrastructure.
