Singapore Maritime Institute on Friday (6 October) said it partnered with several parties to research the potential safety, mitigation technology and environmental challenges in ammonia bunkering.

The partners are Maritime and Port Authority of Singapore (MPA) and Singapore Maritime Institute (SMI), researchers from the Maritime Energy & Sustainable Development Centre of Excellence (MESD) at NTU, A*STAR’s Institute of High Performance Computing (IHPC) and the NUS Tropical Marine Science Institute.

Building on the results obtained in MESD’s previous study, “Ammonia as a marine fuel – bunkering, safety and release simulations”, which was released in October 2022, researchers from the three institutes broadened their research focus to encompass a wider range of factors influencing ammonia release.

The expanded study, titled “Mitigation technology and environmental impact from ammonia bunkering release”, considers different potential ammonia leakage scenarios and aims to develop recommended emergency protocols for addressing such ammonia leaks.

In a video accompanying the post, Venugopalan Raghavan, Lead Research Engineer, Institute of High Performance Computing, A*Star, said: “The project aims to establish advanced modelling and simulation capabilities for ammonia dispersion in sea and air, to develop mitigation technologies for ammonia bunkering in marine environments and assess the environmental impact of ammonia release.”

“The data and insights that we gather through this research will serve as a strong foundation for us to bring solutions to mitigate ammonia bunkering release scenarios in Singapore waters.”

Dr Liu Ming, Research Lead and Project PI, MESD, said “An essential part of our research is a development of practical and effective mitigation solutions. The development and findings we have gleaned from our previous research gave us a clearer understanding and scale of that goal.”

“By examining the existing ammonia mitigation examples and technologies, such as the use of water and physical barriers, we have a strong head start to begin creating effective mitigation solutions for safe ammonia. However, there is no proven mitigation solution to safely resolve ammonia release on the water surface.”

“And this has been a key focus of our research efforts. By solving this challenge, we will have a full range of mitigation solutions that cover the different possibilities of ammonia release. And the fast track the enablement of ammonia bunkering in Singapore. Our research will provide a comprehensive assessment of a safe ammonia bunkering operation.”

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).
