Classification society, RINA, has granted an Approval in Principle (AiP) certificate to MAN Energy Solutions (MAN ES) for its methanol-ready MAN L/V 32/44CR engine, according to the marine engine provider on Monday (13 March). 

The AiP covers an upgrade concept for the four-stroke engine for conversion to dual-fuel running on methanol to provide greater flexibility to shipowners.

Patrizio Di Francesco, EMEA Special Projects Manager, RINA, said: “This AiP is based on our recently published Methyl Alcohol Fuelled Ready notation. Methanol is a fuel with a lot of potential as clean, carbon-neutral fuel and the industry is already showing concrete appreciation of it.  The successful cooperation with MAN is a further step towards the availability of future-proof solutions for shipowners.”

Elvis Ettenhofer, Head of New Marine Solutions, MAN Energy Solutions, said: “This approval by RINA is significant as we move towards net zero. A major advantage of our four-stroke portfolio is its inherent retrofit potential, which enables us to provide shipowners with cost-effective solutions and flexibility regarding future fuels. In this latter respect, there is no doubt but that interest in methanol is growing and that it will have a prominent role to play within shipping.”

In preparation for the fuels that will power a decarbonised future, MAN Energy Solutions is also developing solutions for methanol, which can become carbon-neutral if synthesised with green hydrogen.

The AiP certificate permits the use of outer ship hulls as bunker tanks, thereby increasing fuel-storage capacity on-board.

Chimbusco and SPG achieves first biofuel bunkering operation in Northern China

China Marine Bunker (PetroChina) Co Ltd (Chimbusco) and Shandong Port Group (SPG) recently said they successfully completed the first B24 biofuel bunkering operation in Northern China on 14 June.

Chimbusco’s “DA YUAN YOU 8 ” tanker refuelled the “HMM VANCOUVER” with 1,300 metric tonnes (mt) of B24 biofuel at Qingdao Port.

Chimbusco said the successful bunkering operation not only marks a milestone in the bonded biofuel bunkering business for international voyage vessels in northern China but also represents a critical milestone in the green and low-carbon transformation of the shipping industry around the Bohai Sea and throughout northern China. 

B24 biofuel is a blend of 24% waste cooking oil and 76% high-sulphur fuel oil. Authoritatively certified, the company said this fuel can significantly reduce carbon emissions from vessel operations by up to 20%, providing shipowners with an efficient and convenient low-carbon solution to comply with increasingly stringent International Maritime Organization (IMO) emission reduction regulations. 

Since the beginning of this year, Chimbusco said it has achieved top records of bunkering volumes in the green fuel sector. From the first successful operation at Ningbo-Zhoushan Port in eastern China to subsequent bunkering operations in Shenzhen, Xiamen, and other major ports across the country, the company has further consolidated its regular supply capabilities. 

During this in-depth cooperation with SPG’s Qingdao Port, Chimbusco’s “Green Energy Label” made its debut at the operation site. 

“This further confirms that Chimbusco is deploying green fuel bunkering services to help Chinese ports accelerate the construction of a maritime green energy supply network,” the company said.

Korea to develop global standards for discharge of toxic effluent from ammonia-fuelled ships

Classification society Korean Register (KR) said it has launched a joint working group to establish international standards for the safe discharge of toxic ammonia effluent generated from ammonia-fuelled ships.

Major Korean shipyards such as HD Hyundai Heavy Industries, HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Samho, Samsung Heavy Industries, Hanwha Ocean, and the Korea Testing & Research Institute (KTR) will be part of the group. 

KR said ammonia is attracting attention as an eco-friendly alternative fuel that does not emit carbon dioxide, a greenhouse gas, but due to its strong toxicity and concerns about marine pollution, it is essential to establish separate safety standards. 

In particular, ammonia effluent generated from wet treatment systems currently has no clear treatment standards, which causes considerable technical and operational uncertainty in ship design and operation.

Accordingly, the group aims to establish international standards related to the storage, treatment, and discharge of ammonia wastewater generated from ships and to officially propose this to the International Maritime Organization (IMO) through the Korean government.

The launch of this consultative body is a follow-up measure to a proposal by KR and the Korean government to the IMO in 2024 for the need to establish safety standards for ammonia effluent, which was officially approved at the 83rd IMO Marine Environment Protection Committee (MEPC) in April 2025. The group plans to propose a draft standard to the IMO in 2026 and lead international discussions.

Kim Tae-seong, Head of the KTR headquarters, said: “We will provide reliable scientific data to establish ammonia wastewater management guidelines and treatment standards. We will actively cooperate to secure the international competitiveness of the domestic shipbuilding and shipping industries.”
Kim Kyung-bok, Vice President of KR, said: “This consultative body is a symbolic case of our shipbuilding and shipping industries joining forces to lead the establishment of international safety standards based on our country’s advanced technologies.”

“KR will continue to support the development of alternative fuel safety standards and international standardisation efforts together with our government.”

Fratelli Cosulich Marine Energy and IINO Lines on Thursday (19 June) announced a strategic cooperation that reinforces their shared commitment to the decarbonisation of the maritime industry.

The two companies have signed a Memorandum of Understanding (MoU) to explore new business opportunities in the alternative marine fuels sector. 

“This agreement marks a significant step in the long-standing relationship between the two companies and sets the foundation for further collaboration in the areas of methanol, LNG, and ammonia bunkering,” Fratelli Cosulich said. 

Through the MoU, the parties will engage in joint initiatives, exchange market insights, and facilitate connections with potential suppliers and stakeholders in the alternative fuels space. 

“We are proud to announce the partnership with Fratelli Cosulich for initiatives in alternative marine fuels. Both companies have extensive history in the shipping industry,” said Yusuke Otani, President of IINO Lines. 

“The joint development will enable a holistic approach for building a supply chain of alternative marine fuels.”

“As we navigate the energy transition, partnerships like the one we announce today with IINO Lines are essential in shaping the future of sustainable shipping,” said Timothy Cosulich, CEO of Fratelli Cosulich Group. 

“By combining our expertise and resources, we aim to drive the adoption of cleaner marine fuels and contribute to the decarbonization of global shipping.”
