Lloyd’s Register (LR) and HD Hyundai Heavy Industries (HHI) have signed a joint development project (JDP) for approval in principle (AiP) for a 15,300 TEU Class ammonia-powered dual-fuel container ship.
Under the agreement, HHI has developed a twin skeg design for a 365-metre, ultra-large container vessel (ULCV), which features two small bore engines that are currently available on the market and ammonia fuel tanks positioned ahead of the engine room, far from the deckhouse, helping ensure safe fuel supply operations and better crew habitability.
It is the first design to offer ammonia-powered dual fuel engines for ULCS, as there is currently no large ammonia-powered dual fuel big bore engine technically available and hopes to address concerns from ship owners who are hesitant to adopt ammonia dual fuel systems until they are proven with applicable engine types for ULCSs.
The project aims to complete a full safety review that involves a feasibility assessment for ammonia fuel tanks constructed with low-temperature steel and an evaluation of the structural integrity of the ship against sloshing loads. Additionally, it will review the fuel gas supply system, helping ensure safety and compatibility with ammonia.
LR has reviewed the design to ensure it meets applicable standards of safety and operational efficiency relating to the usage of ammonia. Kim, Young-Doo, GTSO Representative for Korea, Lloyd’s Register said: “There is a growing demand for container vessels that incorporate innovative technologies to comply with stringent regulations and environmental standards for zero carbon.
“Lloyd’s Register is at the forefront of meeting the maritime sector’s need for innovative design development and approval for ammonia fuelled vessels, while also providing our clients and potential clients with access to cutting-edge advancements in ship design and propulsion systems.
“Leveraging our collective expertise and using LR’s extensive experience in certifying ammonia powered designs, this project demonstrates our commitment to supporting the energy transition in the maritime industry.”
Jeon, Seung-ho, Head of Shipping Technology Division at HHI commented: “We are pleased to continue our strong working relationship with LR to develop and test the feasibility of an ammonia duel-fuel containership. With the urgent need for sustainable fuel solutions in the maritime industry, this project seeks to deepen the understanding of ammonia as a marine fuel, setting the stage for future shipbuilding endeavours.”
