Revised IMO

Classification society DNV on Wednesday (17 September) shared a statutory news article that provides a summary of the 11th session of the International Maritime Organization (IMO) Sub-Committee on Carriage of Cargoes and Containers (CCC 11) including new guidelines for the use of hydrogen and ammonia cargo as marine fuel: 

The 11th session of the IMO Sub-Committee on Carriage of Cargoes and Containers (CCC 11) was held from 8 to 12 September 2025. CCC 11 finalized interim guidelines for the use of hydrogen as fuel, interim guidelines for the use of ammonia cargo as fuel, and interim recommendations for the carriage of liquefied hydrogen in bulk. CCC 11 also agreed on a working plan addressing loss of containers at sea.

Meeting highlights

  • Finalized interim guidelines for the use of hydrogen as fuel
  • Revised the working plan for the development of new alternative fuels under the IGF Code
  • Finalized amendments to the IGC Code
  • Finalized interim guidelines for the use of ammonia cargo as fuel
  • Finalized draft amendments to the revised interim recommendations for the carriage of liquefied hydrogen in bulk
  • Worked on amendments to the IMSBC and IMDG Codes
  • Agreed on a working plan to address the loss of containers at sea

Amendments to the IGF Code and the development of guidelines for alternative fuels and related technologies

CCC 11 finalized interim guidelines for the safety of ships using hydrogen as fuel, further developing and describing the established design principles and functional requirements.

The guidelines include functional requirements and detailed provisions for all 20 chapters. The guidelines are limited to liquefied hydrogen concepts, as well as portable compressed and fixed compressed hydrogen concepts, all of which should be fitted on open deck.  

Due to time constraints, no discussion took place on other guidelines such as the guidelines for the use of oil fuels with a flashpoint between 52°C and 60°C as fuel, the revision of the guidelines for methyl/ethyl alcohol as fuel, and the revision of   the fuel cell guidelines. Work on these guidelines will continue in a Correspondence Group and an intersessional Working Group, both reporting to CCC 12 in 2026.  

CCC 11 updated its existing working plan for the development of new alternative fuels under the IGF Code, with the following items assigned as high priority:

  • Revision of the interim guidelines for the safety of ships using methyl/ethyl alcohol as fuel (approval expected 2027)
  • Revision of the interim guidelines for the safety of ships using fuel cell power installations (approval expected 2028)
  • Development of the interim guidelines for the safety of ships using onboard carbon capture and storage systems (approval expected 2029)

IGC Code amendments

CCC 11 finalized the draft amendments to the IGC Code, concluding on implementation dates for new requirements. The draft amendments are expected to be approved by MSC 111 in May 2026, aiming for adoption at MSC 112 at the end of 2026 and entry into force on 1 July 2028.

Guidelines for the use of ammonia cargo as fuel

CCC 11 finalized interim guidelines for use of ammonia cargo as fuel on gas carriers. This provides guidance to ensure the safe handling of ammonia as fuel, with a main focus on issues outside cargo areas to ensure safety for the crew and ship.

Revision of the interim recommendations for the carriage of liquefied hydrogen in bulk

CCC 11 finalized a revision of the interim recommendations for the carriage of liquefied hydrogen in bulk (Resolution MSC.565(108)), adding a new Part D on cargo containment systems of a membrane-type cargo tank maintaining the insulation spaces under vacuum.

CCC 11 also recommended that member states submit a new output proposal on the requirements on training for the carriage of liquefied hydrogen in bulk.

Recommendations

DNV recommends that customers note the finalization of interim guidelines for use of hydrogen as fuel, the updated working plan for the development of new alternative fuels under the IGF Code as well as the completed review of the IGC Code.

As CCC is a Sub-Committee, all decisions concerning rules, regulations and dates are subject to further consideration and approval by the Maritime Safety Committee (MSC).

BHP and GCMD trial multi-feedstock B100 bio bunker fuel on bulk carrier

BHP and the Global Centre for Maritime Decarbonisation (GCMD) on Wednesday (3 June) said they have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project.

The bio-blend in the BHP and GCMD pilot is being used on a BHP-chartered bulk carrier Berge Lyngor, owned and operated by Berge Bulk, transporting BHP iron ore from Western Australia to China. When run on bio-blend, the vessel has the potential to reduce well-to-wake greenhouse gas emissions by approximately 79 per cent per voyage compared to sailing on very low sulphur fuel oil (VLSFO).

The vessel bunkered in Singapore in early May with a B100 bio-blend comprising 50 percent tallow-derived biodiesel, sourced and supplied by HAMR Energy, and 50 per cent used cooking oil (UCOME) supplied by Mitsui & Co Energy Trading Singapore (METS).

Mitsui also blended the fuel and Dan-Bunkering coordinated and executed the bunkering operation, which was performed by Global Energy’s barge MT Maple.

The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure.

At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance.

Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels.

The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance.

Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess.

The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.

This project is co-funded by the Maritime and Port Authority of Singapore under the Maritime Innovation and Technology Fund (MINT).

NYK starts one-year B100 bio bunker fuel trial on car carrier

Japanese shipping firm NYK on Tuesday (2 June) said it has commenced a one-year long-term trial involving the continuous use of 100% biofuel (B100) on an NYK-operated car carrier. 

In this trial, NYK will operate a car carrier continuously on B100 for one year to evaluate the impact on engines, fuel supply systems, and operational practices. High-purity biofuels such as B100 are known to be susceptible to degradation from oxygen, light, and heat, raising concerns about the stability of such fuels during long-term use.

In this trial, the biofuel primarily comprises FAME (Fatty Acid Methyl Ester) derived from used cooking oil and similar feedstocks.

The initiative is designed to evaluate the fuel’s effects on the vessel’s equipment and verify operational safety under real-world conditions. 

Through this effort, NYK seeks to accumulate technical expertise that will support the broader use of high-purity biofuels and further accelerate efforts to reduce greenhouse gas (GHG) emissions.

NYK has been advancing the use of biofuels through various initiatives. In 2024, the company conducted a trial using biofuel blend B24 and subsequently expanded practical usage to B30. However, the company said there remains limited global experience with the long-term continuous use of B100.

“By collecting long-term operational data through this trial, NYK aims to accumulate valuable technical insights to support both the safe operation of vessels and the wider adoption of high-purity biofuels,” it said.
