Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Thursday (13 July) released a bulletin on biofuels for marine use, which was discussed at MEPC 80, specifically in relation to defining the calculation methodology for biofuel’s Conversion Factor (CF) for IMO DCS and CII calculations.

IMO produced an interim guidance with the application date recorded as 1st October 2023. FOBAS outlines the methodology with practical examples:

MEPC 80 concluded last week where GHG emissions from shipping was a top agenda item. One of the key issues under consideration was to provide clarity on the conversion factor (CF) for marine biofuels blends. MEPC 80 came up with an interim guidance (MEPC.1/Circ.905) addressing this aspect. 

As per MEPC.1/Circ.905, biofuels will be considered ‘sustainable’ that have been certified by a sustainability certification scheme (e.g., ISCC or RSB), and providing a well-to-wake GHG emissions reduction of at least 65% compared to the well-to-wake emissions of fossil MGO of 94 gCO2e/MJ (i.e., achieving an emissions intensity not exceeding 33 gCO2e/MJ). The well-to-wake GHG emissions value of the fuel mentioned on the sustainability certificate (expressed in gCO2eq/MJ) is multiplied by its lower calorific value (LCV, expressed in MJ/g) for the purpose of regulations 26, 27 and 28 of MARPOL Annex VI to determine a CF value. For blends, the CF should be based on the weighted average of the CF for the respective amount of fuels by energy. 

Biofuels not certified as ‘sustainable’ or not fulfilling the well-to-wake emission factor criterion should be assigned a CF equal to the CF of the equivalent fossil fuel type. Please see below (Appendix A) few examples which explains the calculation methodology. 

Please note that the application date of this circular has been recorded as 1st October 2023. In view of current variants between flag administrations on the calculation of the CF value, ships should check with their respective flag as to their planned adoption of the MEPC.1/Circ.905. Moreover, this interim guidance will be rescinded upon operationalization of a well-to-wake GHG methodology through the IMO LCA Guideline which is currently under development. 

We trust you will find this guidance document useful and if you are planning to use biofuel blends on your ships, FOBAS can provide further advisory support and comprehensive fuel quality testing service to characterise biofuels to ensure smooth ship operations

AAL Shipping names methanol-ready multipurpose heavy lift vessel in China

Singapore-headquartered project heavy lift carrier AAL Shipping (AAL) on Thursday (13 March) said it held a formal naming ceremony for its fifth Super B-Class vessel, AAL Dubai

The 32,000 dwt AAL Dubai – a multipurpose heavy lift vessel that is methanol-ready – was officially named on March 12 at the CSSC Huangpu-Wenchong Shipyard in Guangzhou, China.

The AAL Dubai is engineered to transport a vast array of cargo, including heavy lift project equipment, breakbulk, and dry bulk, all on a single voyage. With a combined lifting capacity of 700 tonnes, this vessel is designed to offer high efficiency, cargo flexibility, and economies of scale to shippers worldwide.

The vessel will now embark on its maiden voyage, joining sister vessels AAL Limassol, AAL Hamburg, AAL Houston, and AAL Antwerp in serving project cargo customers across Asia, Europe, the Middle East, and the Americas.

“We are now over the halfway mark with our Super B-Class deliveries, and those already in service are exceeding our expectations,” said Liew Teck Liong, Chief Financial Officer at AAL.

“With these vessels, we have achieved both company and industry firsts, and we look forward to redefining what a heavy lift, multipurpose vessel can accomplish as we deploy them for complex cargo challenges.”

Later this year, AAL will take delivery of the AAL Dammam, which will be shortly followed by the AAL Newcastle and AAL Mumbai that have an increased maximum heavy lift capability of 800 tonnes.

Titan completes first LNG and bio-LNG bunkering op to MOL under new term contract

Titan Clean Fuels (Titan) on Monday (17 March) said it has completed the first LNG and liquefied biomethane (bio-LNG) bunkering operation of a new multi-delivery contract for Mitsui O.S.K. Lines’ vehicle carrier fleet.

On 16 March, Titan’s Alice Cosulich LNG bunkering vessel delivered 500 metric tonnes (mt) of bio-LNG and 400 mt of conventional LNG to the Celeste Ace vehicle carrier. The simultaneous operation (SIMOPS) bunkering took place in the Port of Zeebrugge’s International Car Operators (ICO) terminal.

Titan’s delivery of ISCC-EU-certified mass-balanced bio-LNG marks the first of a series of bio-LNG deliveries to the Japanese shipping company. The bio-LNG was produced using waste and residue, which reduces GHG emissions by up to 100% compared to marine diesel on a well-to-wake basis. LNG, bio-LNG, and renewable hydrogen-derived e-methane can be blended at any ratio and ‘dropped into’ existing LNG bunkering infrastructure with little to no modification.

Caspar Gooren, Commercial Director of Renewable Fuels at Titan, said: “This bunkering highlights the growing role of bio-LNG in decarbonizing international shipping today. With bio-LNG availability expanding, its deep decarbonization potential, and increasing commercial viability, the LNG pathway offers practical solutions for shipowners and operators. Moreover, with a global maritime leader like MOL putting its commercial weight behind bio-LNG, this is an exciting time for the clean fuels transition.”

Yoshikazu Urushitani, Marine Fuel GX Division General Manager at MOL, said: “We are exploring the use of ammonia and hydrogen fuels as part of our strategy to adopt clean alternative fuels, while moving to expand the use of LNG-fueled vessels and more quickly achieve a low-carbon society. We will also be early adopters of bio-LNG and synthetic LNG. Partnering with Titan, we will start using bio-LNG to lead the shipping industry in the transition to clean alternative fuels. We remain committed to adopting clean fuels to reach net zero GHG emissions by 2050.”

MOL currently operates five LNG-fuelled vehicle carriers and will have six more delivered by the middle of 2025.
