Pilbara Ports Authority on Monday (6 November) said a feasibility study has highlighted the potential for using clean ammonia to refuel ships, particularly iron ore carriers, visiting the Pilbara region of Western Australia.

The study, commissioned by Yara Clean Ammonia (Yara) and Pilbara Ports, was undertaken by classification society Lloyds Register, and looked at key areas including the estimated demand and likely availability of ammonia as a replacement shipping fuel. The potential risks and regulatory requirements for ammonia bunkering (refueling) at the ports were also considered.

Key results of the study show that safe ammonia bunkering is both economically and operationally viable within the Pilbara region.

The study indicated that ship-to-ship bunkering operations could be performed within acceptable risk levels at anchorages in Dampier and Port Hedland. Moreover, the study confirms that existing ammonia production and export infrastructure within the Pilbara, such as Yara’s Karratha plant and Pilbara Ports’ Bulk Liquids Berth at Dampier, could be leveraged to initiate bunkering operations in the near-term.

The results also show the demand for ammonia as a fuel to decarbonise the international iron ore trade, reaching a volume potential of 1 million to 1.5 million tonnes in 2035.

Yara Clean Ammonia Senior Vice President Commercial Murali Srinivasan said the level of demand reflected the push by iron ore miners and the steel industry to decarbonise.

“The study has shown that a key enabler for meeting this demand is Yara’s existing assets including the world-scale Yara Pilbara Fertilizers ammonia plant near Karratha. Furthermore, the current development of Yuri renewable hydrogen project on the Yara Pilbara site will be the first in Australia to inject green molecules into an existing ammonia plant, and Yara is vigorously exploring options to ramp up volumes of clean and low carbon ammonia to lay the foundation for a reliable supply chain to serve the emerging shipping fuel market.” Mr Srinivasan said.

Pilbara Ports Chief Executive Officer Samuel McSkimming said that, with the carbon reduction efforts in the steel industry supply chain, bulk carriers are a natural starting point for the early adoption of alternative marine fuels.

“The Pilbara contains the world’s largest bulk export ports. Last year we achieved 752.4 million tonnes of trade with more than 6,829 vessel visits. This scale of operations cannot be found anywhere else in the world, and it makes the Pilbara’s ports the natural beachhead from which the global bulk carrier fleet will decarbonise,” Mr McSkimming said.

“The study is an important step towards implementing safe ship to ship ammonia bunkering at our anchorages in Dampier and Port Hedland.

“Ammonia is already widely produced, used, and shipped in industrial quantities around the world. To be able to expand its application as a green shipping fuel would greatly reduce shipping emissions.”

A domestic bunkering industry in the Pilbara would also create new industry and job opportunities for Western Australia and the Pilbara community.

“We are proud to contribute to a green transition in the Pilbara region and more broadly in the global shipping industry. Pilbara Ports is progressing on several strategically significant projects, including major port infrastructure upgrades at Dampier and Port Hedland, to support the production of clean fuels in the Pilbara,” Mr McSkimming said

Pilbara Ports and Yara plan to continue working together as first movers to enable safe  ammonia bunkering in the Pilbara as the switch to zero-carbon shipping materializes.

VO Chidambaranar (VOC) Port Authority on Friday (29 May) said it has signed a Memorandum of Understanding (MoU) with India’s ammonia producer AM Green Ammonia to collaborate in the development of a green ammonia production plant.

The plant will have a capacity of one million tonnes per annum (MTPA) at Tuticorin.

The initiative also includes development of green ammonia handling, storage and bunkering infrastructure, pilot bunkering operations, safety procedures and training programmes. 

The project is expected to support the development of green fuel corridors connecting VOC Port with major ports in Europe and Asia, thereby strengthening India’s position in the global green fuels value chain.

VOC Port also signed a Memorandum of Understanding (MoU) with Bureau Veritas (India) Pvt. Ltd., to collaborate on Green Port certification, emissions accounting, ESG reporting, safety validation, development of green bunkering practices, and establishment of a Centre of Excellence for green fuels and sustainability.

The port also plans for an upcoming 750 m³ green methanol bunkering facility.

Classification society DNV on Saturday (2 May) released technical and regulatory news on the highlights of IMO’s MSC 111 including approved interim guidelines for ships using hydrogen and ammonia cargo as marine fuels as well as endorsed work plans to address regulatory safety barriers to alternative fuels and new technologies.

The following are excerpts of the article: 

The 111th session of the Maritime Safety Committee (MSC 111) was held from 13 to 22 May 2026. The adoption of a new goal-based Code for Maritime Autonomous Surface Ships (MASS) marks a key milestone in the IMO’s work to ensure that the regulatory framework keeps pace with the rapid development of shipping technologies. MSC 111 also approved revised Explanatory Notes for the Safe Return to Port concept for passenger ships, as well as draft amendments to the IGC Code for gas carriers to incorporate a decade of Unified Interpretations, turning operational experience into clearer and more consistent requirements.   

Training for seafarers on alternative fuels and new technologies

MSC 111 approved new “Interim guidelines on training for seafarers on ships using methyl/ethyl alcohol as fuel”, as well as new “Interim guidelines on training for seafarers on ships using amm onia as fuel”.

The fuel-specific guidelines support the generic “Interim guidelines on training for seafarers on ships using alternative fuels and new technologies to support the reduction of GHG emissions from international shipping” (STCW. 7/Circ.25),which were approved by MSC 110 in 2025.

MSC 111 further endorsed the work plan for the further development of training provisions for seafarers on ships using alternative fuels and new technologies.

Ships using hydrogen as fuel 

MSC 111 approved “Interim using hydrogen as fuel” guidelines for the safety of ships

Ships using ammonia cargo as fuel

MSC 111 approved “Interim guidelines for use of ammonia cargo as fuel on gas carriers”. These guidelines aim to support the safe handling of ammonia as fuel, with main focus on areas outside the cargo areas to ensure safety for the crew and ship.

IGC Code – ships carrying gases or low flashpoint fuels 

MSC 111 approved draft amendments to the IGC Code to incorporate the large number of Unified Interpretations (UIs) developed since the latest major review of the code, which entered into force in 2016. The primary objective of the draft amendments is to remove ambiguity and promote the consistent implementation of the IGC Code requirements.

The draft amendments to the IGC Code are expected to enter into force on 1 July 2028, subject to adoption by MSC 112 (December 2026).

The draft amendments to the IGC Code will apply to ships constructed on or after 1 July 2028, i.e. ships:

for which the building contract is placed on or after 1 July 2028; or in the absence of a building contract, the keels of which are laid or which are at a similar stage of construction on or after 1 January 2029; or the delivery of which is on or after 1 July 2032.

Draft amendments to the model form of the International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk in Appendix 2 of the IGC Code were approved to reflect the three-date application provision.

The following MSC Circulars, containing UIs to the IGC Code, are expected to be suspended upon adoption and entry into force of the IGC Code amendments:

  • MSC.1/Circ.1543, MSC.1/Circ.1559, MSC.1/Circ.1590,
  • MSC.1/Circ.1606, MSC.1/Circ.1617, MSC.1/Circ.1625,
  • MSC.1/Circ.1651, MSC.1/Circ.1669 and MSC.1/Circ.1679.

ITOCHU orders world’s first ammonia bunkering vessel for Singapore demonstration project

ITOCHU Corporation (ITOCHU) on Wednesday (20 May) announced that the Maritime and Port Authority of Singapore (MPA) has granted authorisation to ZETA Bunkering Pte Ltd (ZETA), a wholly owned subsidiary of ITOCHU, to conduct ammonia bunkering trials in Singapore.

The authorisation was granted following MPA’s review of ZETA’s submissions, which included comprehensive safety studies, risk assessments, and business plans for ammonia bunkering in Singapore. 

The ammonia bunkering trials to be conducted under this authorisation will serve to verify the technical readiness, operational protocols, infrastructure, and technologies, to assess and inform the development of safe and environmentally sustainable ammonia bunkering practices in Singapore. The authorisation was issued on 27 April and will become effective on 15 May for a trial period up to two years subject to MPA’s prevailing regulatory framework.

In June 2025, as part of ITOCHU’s integrated project for developing and owning of ammonia-fuelled vessels and the establishment of a global supply chain for ammonia as marine fuel, ITOCHU placed an order for the world’s first newbuilding ammonia bunker vessel, through Clean Ammonia Bunkering Shipping Pte Ltd, a wholly owned subsidiary of ITOCHU. The vessel is being constructed by Sasaki Shipbuilding, will be flagged under the Singapore Registry of Shipping and is expected to be delivered in September 2027.

The authorisation will accelerate ITOCHU’s initiatives to decarbonise international shipping. Specifically, ITOCHU plans to conduct demonstration trials in collaboration with Mitsui O.S.K. Lines, Ltd. (MOL), supplying ammonia fuel from the ammonia bunker vessel to dual-fuel Capesize bulkers, jointly owned by CMB.TECH NV (Belgium) and MOL, and chartered by MOL, within the port of Singapore during the last quarter of 2027, subject to the relevant regulatory approvals.

Through these demonstrations and subsequent ammonia bunkering trial operations under the authorisation, ITOCHU will work closely with MPA and other maritime stakeholders to develop infrastructure, technologies, and operational standards for ammonia bunkering that prioritise safety and environmental sustainability. ITOCHU will also formulate detailed implementation plans, conduct risk assessments, and establish emergency response measures, ensuring that safety and environmental protection remain paramount.

These trials will enable ITOCHU to establish safe and sustainable ship-to-ship bunkering operations using ammonia as marine fuel, with the aim of commercialising the ammonia bunkering business in Singapore and at major maritime hubs worldwide.
