Hanwha Engine

Hanwha Engine is the leading player in low speed diesel and gas power plants.
Our expertise
  • Marine engines: Design, manufacture, and sales of large, low-speed marine propulsion engines
  • Aftermarket business: Engine part sales and technical services
  • Selective Catalytic Reduction (SCR) business: Design, manufacture, and installation of NOx reduction systems (DelNOx) for ships

Hanwha Engine, integrated into the Hanwha Group in February 2024, aims to become a driving force in the maritime industry, ensuring a safer and more environmentally friendly future through its distinctive technological prowess and comprehensive lifecycle management capabilities for large, low-speed marine engines.

 

Since its establishment in 1983, Hanwha Engine has achieved several noteworthy milestones, including production of the world’s largest engine, commercialization of the world's first dual-fuel engine, and development of our world-class self-developed NOx reduction system, DelNOx. Based on the market dominance of our main business, low-speed engines, we have recently expanded into the field of high-value-added, eco-friendly engines, concentrating on the production of low-emission methanol propulsion engines and the development of low-carbon emission ammonia propulsion engines.

Hanwha was the first in the world to produce a large, electronically controlled ME engine in 2003.

The aftermarket business plays an important role in ensuring safe ship operations for customers. Hanwha Engine has built facilities at major ports to provide customers with parts whenever they need them, while also providing engine repair and inspection services performed by skilled, experienced service engineers with extensive industry expertise. Hanwha Engine provides customized solutions through big data, as well as planned maintenance via long-term service agreements that are valid for the engine’s lifetime. Through services like these, Hanwha Engine ensures that all of our engines operate in optimal condition at peak performance.

 

SCR is Hanwha Engine’s key business area and where our core technology is concentrated. In 2013, we successfully applied our proprietary technology to develop the world’s first low-temperature SCR system for ships, satisfying the International Maritime Organization (IMO)’s strengthened nitrogen oxide (NOx) emission regulations, which went into effect in 2016. Today, we have expanded our specifications to cover high-temperature SCR-systems, further solidifying our position as a complete engine solutions provider for NOx reduction.

 

To preemptively respond to decarbonization needs of the marine engine market, we are diversifying our eco-friendly engine portfolio and focusing on securing decarbonization engine technology. Through these approaches, we will respond flexibly to changes in the market while creating new revenue streams. With a focus on developing smart ship solutions to ensure efficient and safe vessel operations, Hanwha Engine will continue to provide innovative value to customers worldwide. In the mid- to long-term, we plan to secure sustainable growth by concentrating our capabilities on retrofitting existing ships to run on eco-friendly engines. Through this, we will lead the marine engine market in the decarbonization era and present cutting-edge technological solutions that meet customer needs.

Hanwha Engine commercialized the world's first dual-fuel low-speed engine for ships in 2013.
