With five decades of marine engine manufacturing experience, STX Engine's selection by a leading global shipowner like Maersk highlights the company's technological capabilities and reliability. The deal positions STX Engine to strengthen its presence in the global eco-friendly marine engine market and reflects growing demand for dual fuel propulsion technology among major container lines. This contract also signals increased competitiveness for Korean marine engine manufacturers in the global shipbuilding supply chain, supporting the industry's transition to greener shipping solutions.
