Classification society RINA on Monday (3 June) said it partnered with technology group Wärtsilä and Italian firm specialising in cargo handling systems Gas and Heat for a project of an ammonia fueled bunkering vessel to deliver and operate on green ammonia fuel.

Within this agreement, Gas and Heat will develop the basic design of the cargo handling system, while Wärtsilä will support the project through designing an optimised integrated propulsion solution in which the core element will include its recently introduced 4-stroke engine-based solution for ammonia fuel, the Wärtsilä 25 engine ammonia engine; RINA will then carry out the compliance assessment of the design as part of the wider Approval in Principle process.

Giuseppe Zagaria, Marine South-West Technical Director at RINA, said: “RINA has long history of cooperation with Wärtsilä and we are very proud to work together once again, strengthening our project. Wärtsilä’s expertise will upgrade the technological content of our collaboration. Green ammonia has great potential to play an important role in the strategies set by IMO and EU, which will need innovative bunkering vessels to support the logistics and supply of green ammonia”.

“Green ammonia is one of the alternative fuels of the future. We are excited that Warstila as joined our partnership with RINA to collaborate in this ambitious project. Gas and Heat is proud to work with these high level companies to offer this innovative vessel to the market” says Claudio Evangelisti, CEO, Gas and Heat Italy.

“At Wärtsilä we are fully committed to supporting the industry with reducing greenhouse gas emissions, which is why we are proud to be partnering with RINA and Gas & Heat in this industry-leading project,” says Stefano De Marco, Business Development, Decarbonisation Services, Wärtsilä Marine.

“Sustainable ammonia is one of the leading candidates in shipping’s search for alternative sustainable fuels, and the delivery of our new Wärtsilä 25 Ammonia solution will deliver the project’s overarching goal of enabling the transition to greener fuels in shipping.”

HPA and MB Energy develop safety concept for STS ammonia bunkering

The Hamburg Port Authority (HPA) and integrated energy company MB Energy on Tuesday (21 July) said they have completed a comprehensive risk analysis and developed a dedicated safety concept for ship-to-ship ammonia bunkering.

MB Energy said the analysis lays the groundwork for the safe introduction of ammonia as a future marine fuel.

“With our planned ammonia import terminal in Hamburg-Blumensand, MB Energy intends to provide the reliable land side supply infrastructure needed to support this transition across northern German ports,” it said in a social media post.

Mabanaft Group was renamed to MB Energy last year and merged over 50 existing brands under one identity.

Separately, HPA said the Port of Hamburg will become “bunker ready” for ammonia, laying the groundwork for safe and reliable ammonia bunkering in the future.

“The focus is in particular on container ships, cruise ships as well as RoRo and ConRo (Container/RoRo) ships,” it said.

“We expect ammonia to establish itself as an alternative marine marine fuel in the coming years. With our preparatory work, we are already creating the conditions to welcome the first ammonia-powered ships in Hamburg and to bunker them safely.:

HPA added that the import terminal for ammonia planned by MB Energy from 2029 will make a decisive contribution to ensuring the reliable availability of ammonia as a bunker fuel in northern German ports in the long term.

“The use of an ammonia bunker barge is considered a possible addition to the landside infrastructure to enable ship bunkering in the port and beyond in the future,” it said.

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.”
