China’s SDARI receives AiPs for alternative-fuelled ships including ammonia bunker vessel

China State Shipbuilding Corporation’s (CSSC) Shanghai Merchant Ship Design and Research Institute (SDARI) recently obtained Approval in Principle (AiP) certificates from several classification societies for four vessel designs. 

Among the four is a 50,000 cubic metre (m3) ammonia bunkering vessel, which received AiP certificate from American Bureau of Shipping (ABS). 

It integrates liquid ammonia transportation and bunkering functions and can meet the long-distance transportation needs of liquefied gas goods such as liquefied petroleum gas (LPG) and liquid ammonia. 

The ship is equipped with three IMO Type A independent liquid cargo tanks, and uses zero-carbon ammonia fuel to drive the main engine and generator, meeting the IMO greenhouse gas emission reduction strategy and actively responding to the latest greenhouse gas intensity (GFI) requirements of the 83rd meeting of the IMO Marine Environment Protection Committee (MEPC 83). 

The entire ship is equipped with two independent 1,000 m3 deck liquid ammonia storage tanks, taking into account the ammonia fuel endurance requirements under multi-cargo loading and unloading, significantly improving operational economy and flexibility. 

In response to the needs of bunkering operations, it is specially equipped with a retractable bow thruster, side thruster and adjustable propellers to meet ABS’ DPS-1 notation and adapt to the complex port environment of bunkering operations.

Meanwhile, a dual-fuel LNG/hydrogen-powered Ultramax bulker design and a 30,000 GT Roll-On/Roll-Off Passenger (ROPAX) ship designed to sail in the Mediterranean Sea received AiP certificates from RINA. 

SDARI also received AiP from Lloyd’s Register (LR) for a 113,000 dwt ammonia dual-fuel liquid cargo ship. The optimised propulsion system, specially configured with an ammonia dual-fuel power system and a wind-assisted propulsion system, is expected to save more than 10% energy, especially at low speeds.

President MT

The 50th vessel constructed by local boat builder Pinnacle Marine (Singapore) Pte Ltd, namely President 100, is starting 1,000 hours of real-time research trials in collaboration with several parties from Wednesday (9 July) onwards, it says.

Powered by B100 biodiesel, the newbuilding operated by Prestige Ocean Pte Ltd will capture data on bunker fuel emissions, marine fuel behaviour, and performance.

It will be participating in trials with Maritime Energy & Sustainable Development Centre of Excellence (MESD), Weichai Singapore, China Classification Society, Pacific International Lines (PTE) Ltd, Abo Shoten, Ltd. / 株式会社安保商店 , Abo Singapore, Wilmar International, Gulf Marine, Amspec Testing & Services, and AYK Engineering and Consulting.

The President 100, Pinnacle Marine’s first full biodiesel utility boat, was launched on Tuesday in the presence of over 100 guests.

“Our latest vessel, President 100, merges legacy and future. Named after our first aluminium boat (“President”) and inspired by B100 biodiesel, it leads the charge for our next 50 vessels — many of which will embrace green technology,” stated Pinnacle Marine in a LinkedIn post.

“The launch was amazing, with strong turnout from across the maritime sector — authorities, shipowners, operators, agencies, chandlers, researchers, offshore engineers, and petrochemical suppliers.”

It added: “We’re excited to see how it paves the way for wider adoption of B100 biodiesel — a cleaner, sustainable path for Singapore’s harbour craft sector.”

BHP ammonia DF charters

Global resources company BHP on Wednesday (2 July) signed contracts with COSCO Shipping Bulk Co., Ltd., a subsidiary of COSCO shipping Group (COSCO Shipping) for the charter of two ammonia dual-fuelled Newcastlemax bulk carriers.

The new vessels to be built under this arrangement will be two of only a handful of vessels in the world capable of using ammonia as a bunker fuel.

The two vessels, expected to be delivered from 2028, will primarily transport iron ore from Western Australia to Northeast Asia.

When run on lower or low to zero greenhouse gas (GHG) emissions ammonia, these vessels will be capable of reducing GHG emissions by at least 50% and up to 95% on a per voyage basis compared to a conventionally fuelled voyage.

The five-year time charter contracts are expected to contribute towards a reduction in the GHG emissions intensity of BHP chartered shipping.

BHP continues to work with the maritime industry to develop an ammonia bunkering plan – the process of fuelling ships with ammonia – for the two vessels when they are delivered from 2028.

Sourcing lower and low to zero GHG emissions ammonia is subject to an ongoing tender process.

Chimbusco x BJEC MT

China Marine Bunker (PetroChina) Co.,Ltd. (Chimbusco) and POWERCHINA Beijing Engineering Corporation Limited (BJEC) on Thursday (3 July) formally entered into a green methanol strategic cooperation framework agreement.

The document was signed between Ding Lihai, deputy general manager of Chimbusco, and Li Jianjun, deputy general manager of BJEC.

BJEC, a subsidiary of China Power Engineering Group, is experienced in the survey, design, construction and technology research and development of large-scale renewable energy projects.

Moving forward, the two parties said they will respectively focus on their core advantages and work together to promote the production, supply, storage and refuelling of green methanol as an energy source to help support the low-carbon transformation of the shipping industry.

Ding Lihai said: “The shipping industry is one of the important sources of global carbon emissions. Promoting low-carbon fuel is the key to the transformation of the industry. As the main force in the supply of bunker fuel, Chimbusco has been committed to expanding its clean fuel supply capacity. The cooperation with BJEC will integrate the advantages of green energy development and fuel supply, accelerate the large-scale application of green methanol, and meet the needs of shipping companies for clean fuel. We look forward to providing effective solutions for the green transformation of the shipping industry through the joint efforts of both parties.”

Li Jianjun said: “Implementing the ‘dual carbon’ goal is an important responsibility of enterprises. BJEC has accumulated strong technical strength in the field of green energy. This cooperation with Chimbusco will focus on the entire industrial chain of green methanol, from raw materials, production to supply, to provide clean and sustainable fuel solutions for the shipping industry. The complementary advantages of both parties will promote the rapid development of the green methanol industry and inject strong impetus into the low-carbon transformation of the shipping industry.”
