ONEX Shipyards and Technology said on Thursday it has signed an agreement with Hanwha Power Systems to expand joint activities in the United States spanning shipbuilding, energy production and regasification units.

The Greek shipyard operator said the agreement also covers work tied to power generation, shipyard efficiency and energy storage platforms.

In the same statement, ONEX Shipyards and Technology CEO Panos Xenokostas said Hanwha Power Systems and ONEX Shipyards and Technology are joining forces to help bring maritime energy production back to the United States and to accelerate development of critical energy infrastructure.

The announcement comes after the Trump administration said last year the U.S. would work with South Korea to support the struggling U.S. shipbuilding industry and to help enable shipbuilding in the country.

The U.S. also backs Greece’s effort to position itself as an energy hub in the Balkans and to supply central and southern Europe with U.S.-produced liquefied natural gas (LNG).
