Ammonia powered mega-boxship five years away

An ammonia powered ultra-large container ship will be commercially available by 2025 says classification society Lloyd’s Register (LR) which has awarded a South Korean shipyard an Approval in Principle for its vessel design.

UK-based LR gave the Daewoo Shipbuilding & Marine Engineering (DSME)’s 23,000TEU vessel design its approval with the ship design expected to use an MAN Energy Solutions main engine adapted for the purpose.

An LR statement said, “As part of the Joint Development Project, DSME generated the basic design of the ammonia propulsion system and MAN Energy Solutions was responsible for the development and specifications of the ammonia dual fuel propulsion engine.”

The class society added that its role was to review the design including looking at the its suitability and a “hazard identification (HAZID) workshop, a hazard & operability analysis (HAZOP) workshop and a design review in accordance with the Approval of Risk-Based Design (ARBD) process, which led to Approval in Principle.”

Following the AiP the design will move to the second stage of its development which includes making certain the vessel will be commercially viable as well as being safe to operate.

The partners said that, “The ammonia-fuelled 23,000 TEU ultra-large container ship is expected to be commercialised by 2025.”

Odin Kwon, Vice President / CTO at DSME, commented: “Working with Lloyd’s Register and MAN Energy Solutions, DSME has developed the zero carbon ammonia (NH3) fuelled container ship, a more complex design than that of other ship types because the ammonia fuel tank and much of the fuel facility and safety equipment is installed in an enclosed space.”
