Classification society DNV on Tuesday (24 September) released a statutory news on the 10th session of the IMO Sub-Committee on Carriage of Cargoes and Containers (CCC 10). The following are excerpts from the update related to bunker fuel:

The 10th session of the IMO Sub-Committee on Carriage of Cargoes and Containers (CCC 10) was held from 16 to 20 September 2024. CCC 10 agreed on interim guidelines for use of ammonia as fuel, completed the review of the IGC Code, and revised recommendations on entering enclosed spaces.

Meeting highlights
Finalized work on interim guidelines for use of ammonia as fuel.
Continued work on interim guidelines for use of hydrogen as fuel and on interim guidelines for use of low-flashpoint fuels.
Completed review of the IGC Code.
Worked on amendments to the IMSBC and IMDG Codes.
Completed revised recommendations for entering enclosed spaces aboard ships.
Agreed on a work plan to address loss of containers at sea.

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

CCC 10 finalized interim guidelines for the safety of ships using ammonia as fuel. The guidelines include functional requirements for all sections. Due to time constraints, detailed provisions could only be developed for parts of the guidelines. For the remaining parts the principles of the IGF Code should be taken into consideration.

CCC 10 also continued work on the interim guidelines for the safety of ships using hydrogen as fuel, agreeing on functional requirements for all sections of the guidelines, and on certain fundamental design principles. Work on the interim guidelines will continue in a Correspondence Group aiming for finalization in 2025.

The interim guidelines for use of oil fuels with a flashpoint between 52°C and 60°C as fuel were not discussed, but work will, if time permits, continue in a Correspondence Group reporting to CCC 11 in 2025.

Proposals for amendments and Unified Interpretations to the IGF Code were not considered in detail at CCC 10. They will be discussed by a Correspondence Group and further considered at CCC 11 in 2025.

Review of the IGC Code

A Correspondence Group may be established, pending a decision by MSC, to consider the development of interim guidelines for the use of ammonia cargo as fuel.

The complete amendment proposal will be further considered by MSC 109 in 2024, aiming for adoption in 2025 and entry into force on 1 January 2028.

Recommendations

DNV recommends that customers note the development of interim guidelines for use of ammonia as fuel, 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).

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions.

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post.

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said.

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels.

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
