Daewoo Shipbuilding & Marine Engineering Leads Eco-Friendly Ship Market with Ammonia-Powered Vessel Development

[Asia Economy Reporter Park So-yeon] Daewoo Shipbuilding & Marine Engineering (DSME) has embarked on pioneering new markets by leveraging world-class technology in the eco-friendly ship sector.

DSME announced on the 6th that it has obtained the Approval in Principle (AIP) from Lloyd's Register (LR), a global classification society based in the UK, for a 23,000 TEU-class ammonia-powered ultra-large container ship.

Since June, DSME has been jointly conducting an ammonia-powered vessel development project with Lloyd's Register and MAN Energy Solutions, a global engine manufacturer.

In this joint development project, DSME was responsible for the basic design of the ammonia propulsion system, MAN Energy Solutions handled the development of the ammonia dual-fuel propulsion engine, and Lloyd's Register reviewed the risks and suitability of the equipment.

Ammonia is an eco-friendly alternative fuel that emits zero carbon dioxide during combustion and is attracting industry attention due to its ease of transport and storage. It also meets the IMO regulations requiring a 70% reduction in carbon dioxide emissions by 2050, increasing shipowners' interest.

Notably, this certification included not only a safety review of the overall equipment (HAZID) but also a detailed safety review (HAZOP) of design drawings and piping, completing a thorough verification of safety.

Kwon Oh-ik, Executive Vice President and Head of Technology at DSME, said, "With this Approval in Principle for ammonia-powered ships, we have taken a step closer to DSME's ultimate goal of decarbonization. Especially since we successfully completed certification for the complex construction of container ships, it will be even easier to apply this to general ship types in the future."
