KR and partners to develop safety guidelines for ship-to-ship ammonia bunkering

Classification society Korean Register (KR) on Wednesday (13 November) said it has formed a landmark partnership to develop the safety guidelines for ship-to-ship ammonia bunkering through a Memorandum of Understanding (MoU) with HD Korea Shipbuilding & Offshore Engineering (HD KSOE), HD Hyundai Heavy Industries (HD HHI), KSS Line, and the Liberian Registry.

As the demand for ammonia-fuelled vessels rises, the partnership aims to establish robust safety standards for STS ammonia bunkering, an efficient method for supplying fuel to ammonia-fuelled vessels.

“The safe bunkering of alternative fuels, like ammonia, requires rigorous risk assessment and the establishment of controlled zones,” KR said in a statement.

“While standards for LNG and methanol bunkering have already been defined through various international industry standards, ammonia currently lacks relevant guidelines, highlighting the urgent need for the partnership’s research.”

To address this industry need, the five organisations involved will work together to develop standardised safety procedures that will set international benchmarks for ship-to-ship ammonia bunkering.

As part of the initiative, HD KSOE will perform risk assessments aligned with international industry standards, while HD HHI and KSS Line will utilise their expertise and experience in alternative-fuel vessels and ammonia carriers to evaluate controlled zones and safety procedures for ammonia STS bunkering.

KR will verify the compliance of these safety procedures and issue an Approval in Principle (AIP) certificate. The Liberian Registry, overseeing the world’s largest registered fleet, will further review the validity of these safety procedures.

KIM Yeontae, Executive Vice President of KR’s technical division, said: “With the expected rise in ammonia bunkering demand driven by the construction of more ammonia-fueled vessels, this collaborative effort to establish safety standards is highly significant.”

“Through this partnership, KR is committed to advancing ammonia fuel technology and supporting the industry’s decarbonisation efforts.”

KIM Jungsik, Managing Director of the Korea Office at the Liberian Registry, said, “Just as we observed with the initial adoption of LNG STS bunkering, it is critical to establish regulations and procedures for ammonia as well.”

“Our Innovation and Energy Transition team will thoroughly review the safety protocols and support the development of international standards.”

EXMAR’s “ANTWERPEN” completes first commercial voyage using ammonia bunker fuel

Belgian shipowner EXMAR on Monday (20 July) announced the successful completion of gas carrier ANTWERPEN’s first commercial voyage using ammonia as a marine fuel.

During its voyage from China to India, the vessel achieved ammonia dual-fuel operation fully in line with our expectations and design, demonstrating that the technology works in commercial service.

“Together with our partners, we continue to fine-tune the systems as we build on this outstanding achievement. We are proud of our crew for their excellent pioneering work,” the company said in a social media post.

Developed in close collaboration with HD Hyundai Heavy Industries, WinGD, Nord Gas Solutions (formerly Wärtsilä Gas Solutions), and Lloyd’s Register, ANTWERPEN is capable of carrying up to 46,000 m³ of ammonia or LPG and trading with close to zero emissions when using low-carbon ammonia fuel.

The vessel meets and exceeds current IMO emissions reduction targets, reducing greenhouse gases by up to 90% compared to conventional ships.

Manifold Times previously reported ANTWERPEN participated in a pipe-to-ship (PTS) ammonia bunkering operation in Ulsan Port.

The operation was carried out by Lotte Fine Chemical Co Ltd with 600 metric tonnes (mt) of green ammonia (NH3) supplied to ANTWERPEN.

KR, HD Hyundai tap first ammonia dual-fuel sea trial to develop vessel operating standards

Korean Register (KR) on Tuesday (14 July) said it is collaborating with HD Hyundai Heavy Industries (HHI) to establish a domestic operating environment for ammonia-fuelled vessels under the Ministry of Oceans and Fisheries’ Green Shipping Corridor Construction Support Project.

The initiative supports the development of ammonia as one of the most promising next-generation marine fuels.

HHI recently conducted a sea trial of Korea’s first ammonia dual-fuel propulsion vessel. The trial generated operational data on the vessel’s fuel supply system and engine, which will provide a valuable technical foundation for KR’s future development of domestic guidelines for environmentally friendly vessel operations and supporting wider maritime decarbonisation efforts.

A spokesperson for HD Hyundai, said: “Drawing on our group’s R&D capabilities and on-site technical expertise, we have made meaningful progress in advancing the application of ammonia as a marine fuel. We expect this to help enhance a sustainable maritime ecosystem while strengthening the competitiveness of Korea’s shipbuilding industry.”

Kim Daeheon, Executive Vice President of KR’s R&D Division, added: “The close collaboration between KR and HD Hyundai has enabled us to build the technical foundation for introducing ammonia-fueled vessels in Korea. We will continue to drive national projects forward together with HD Hyundai and establish technical standards befitting the era of Green Shipping Corridors.”

Sales of marine fuel at Singapore port increased by 1.6% on year in June 2026, according to data from the Maritime and Port Authority of Singapore (MPA).

In total, 4.67 million metric tonnes (mt) (exact 4,669,100 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in June, up from 4.59 million mt (4,594,700 mt) recorded during the similar month in 2025.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in June (against on year) recorded respectively 2.03 million mt (+19.4% from 1.70 million mt), 2.20 million mt (-4.8% from 2.31 million mt), zero (-100% from 1,900 mt), 1,900 mt (-57.8% from 4,500 mt) and zero (from zero).
