The Global Centre for Maritime Decarbonisation (GCMD) on Tuesday (15 August) said it successfully bunkered the third supply chain of a biofuel blend as part of its pilot to develop a quality, quantity and GHG abatement assurance framework for drop-in green fuels on 24 July.

Partnering with tonnage provider Eastern Pacific Shipping (EPS), this GCMD-led trial involved the Kaupang, a mid-sized gas carrier equipped with an LPG dual-fuel engine. As opposed to sailing on conventional fuel oil, LPG propulsion can reduce emissions. Using LPG requires a pilot fuel; replacing the pilot fuel with a biofuel blend can further reduce emissions.

In this trial, approximately 200 metric tonnes (mt) of a B30 biofuel blend of hydrotreated vegetable oil (HVO) and marine gas oil (MGO) provided by GoodFuels was bunkered in the Port of Vlissingen (Flushing) as the pilot fuel for LPG propulsion.

Prior to this trial, GCMD had successfully traced two supply chains of FAME-based biofuels blends with synthetic DNA from production to consumption through Singapore. In this most recent trial, GCMD collaborated with GoodFuels, Control Union and IDS to deploy an element-based tracer in HVO to assure its origination and quantity in the biofuel blend.

Unique to this trial, the tracer was dosed in-line with HVO and blended with MGO onboard the bunker vessel. Carbon dating was conducted in accordance with Standard EN 16640 to independently determine the biogenic carbon content given the chemical similarities between HVO and some of the components in MGO.

VPS witnessed the trial at all stages from biofuel transfer and onboard blending to bunkering aboard the Kaupang. VPS also conducted extensive laboratory tests on aliquots of the biofuel and biofuel blend collected at numerous pre-determined points along the supply chain to assess quality per Standards EN 15940 and ISO 8217.

Aligning with the key outcomes of MEPC 80

MEPC 80 has issued MEPC.1/Circ.905 Interim Guidance on the Use of Biofuels under Regulations 26, 27 and 28 of IMO MARPOL Annex VI (DCS and CII), which will come into effect on 1 October 2023. These interim guidelines will provide clarity on the types of biofuels that can be certified sustainable; these biofuels will also need to meet a minimum requirement of 65% emissions reduction against conventional fuel to be compliant.

Produced from 100% waste and residues, the HVO used in this trial has a well-to-wake emissions of 16 gCO2e/MJ. This translates to a 83% reduction in emissions compared to using fossil MGO, and in blending MGO with 30% biofuel as the pilot fuel for LPG combustion, this trial demonstrated a 20% net reduction in emissions compared to the Kaupang sailing on VLSFO.

The data collected from this trial augments those collected from the prior two supply chain trials for GCMD to further develop its assurance framework for drop-in green fuels. In the context of the recently updated guidelines, this framework should impart greater confidence in fuel purchasers meeting or exceeding IMO regulatory requirements.

On the completion of bunkering of this drop-in biofuel supply chain trial, Dr Sanjay Kuttan, Chief Technology Officer of GCMD, said: “The experiences from this trial will strengthen the development of our framework to provide emissions abatement assurance when it comes to paying a premium for green fuels over fossil fuels. Through this pilot, we demonstrated that different tracing techniques can help ensure authenticity and quantity of sustainable biofuels in the supply chain. And using a biofuel blend with LPG can be a feasible pathway for ships to meet the recently revised IMO indicative decarbonisation checkpoint for 2030.”

Rashim Berry, Senior Advisor-Special Projects of Eastern Pacific Shipping, said: “Eastern Pacific Shipping is pleased to once again team up with GCMD and GoodFuels on a biofuel trial. EPS’ stance has always been to implement various emission lowering solutions, such as biofuels, across our diverse fleet. Our previous trial proved that biofuels lower CO2 emissions. Therefore, we must keep pushing the envelope by conducting additional testing, including supply chain integrity. This is the only way to develop a viable solution in the biofuels space that the entire shipping community can adopt. We believe this trial will do just that.”

Johannes Schürmann, Commercial Director at GoodFuels, said: "By applying our groundbreaking physical fuel tracing technology in practice in this pilot, we are jointly taking another significant stride towards a more transparent bunker industry that is geared towards decarbonisation in a scaleable way. Transparency is becoming even more crucial as we are now starting to bring the new generation of Sustainable Marine Fuels to market. The ability to access reliable technical insights and sustainability guarantees in every step of the supply chain is absolutely essential."

The remaining two supply chains of the GCMD-led biofuels assurance framework pilot will be trialled in the upcoming months. Learnings from these trials and details of the assurance framework will be shared broadly through a public report in early 2024.

Hercules Tanker Management vessel “Mount Kibo” takes on B30 bio bunker fuel

Hercules Tanker Management (HTM) on Tuesday (29 April) announced that its tanker Mount Kibo has been successfully supplied with B30 bunkers by tanker Hercules Sky, another HTM-owned vessel which is operated by Peninsula.

The operation marked the first biofuel supply to the HTM fleet.

HTM is the shipping venture launched last September by John A. Bassadone, founder and CEO of independent marine fuel supplier Peninsula.

HTM said the operation carried out in the Strait of Gibraltar aligns with the recent discussions at MEPC 83, where key decisions were made to advance maritime decarbonisation, including new fuel standards and a global pricing mechanism for emissions.

“Additionally, this initiative supports the objectives of the FuelEU Maritime Regulation, which promotes the use of renewable, low-carbon fuels and clean energy technologies for ships,” it said.

“By utilising biofuels, we are contributing to the reduction of greenhouse gas emissions and supporting the industry's transition towards cleaner energy solutions.”

Classification society DNV on Monday (28 April) released an article summarizing how shipowners can apply a practical, structured approach to gaining approval for ammonia- or hydrogen-fuelled ships.

From engaging early with flag administrations to addressing design risks, training crews, and managing bunkering safely, DNV described seven essential steps to receive approval:

The paper – Safe introduction of alternative fuels: Focus on ammonia and hydrogen as ship fuels – offers a structured pathway for shipowners to achieve approval through IMO’s alternative design approval (ADA) process.

Seven steps to obtain approval for ammonia- and hydrogen-fuelled ships

“We outline seven steps to assist shipowners and other stakeholders in obtaining approval and safely deploying ammonia- and hydrogen-fuelled ships in today’s immature regulatory environment,” says Linda Hammer, Principal Consultant, Environment Advisory at DNV and lead author of the white paper. “The regulatory path is certainly complex, but the steps and safety measures in the paper add up to a clear, achievable pathway to ship approval and safe operations. It also explains how DNV’s support can significantly ease this process through its tailored rule sets and learnings from pilot projects.”

Understanding ADA phases: From initial design to final approval

IMO’s IGF Code (International Code of Safety for Ship Using Gases or Other Low-flashpoint Fuels) currently covers natural gas but not ammonia or hydrogen. Without detailed regulations, IMO’s risk-based ADA process (MSC.1/Circ.1455) is used. It involves demonstrating that the ship’s safety level is equivalent to that of conventional oil-fuelled vessels.

t4 ind 586 milestones in the two phases (1)

ADA has two main phases. A preliminary design approval requires a hazard identification (HAZID) study, developing a preliminary risk assessment, and defining preliminary risk-control measures and safety strategies.

Phase two, final design approval, starts with refining the design with detailed technical and safety documentation, then making a final risk assessment, addressing integration and operation-specific concerns. Then come complete system integration testing and submitting findings to the flag administration.

Role of class and flag administrations in approval process

As the IMO regulatory framework progresses towards eventually amending the IGF Code, classification societies like DNV can give shipowners a head start in designing vessels by issuing class certificates and providing prescriptive rule frameworks to support ADA.

Flag administrations enforce statutory regulations and have the final say on approvals. Early and active engagement with the relevant flag administration is therefore the key to clarifying approval expectations and streamlining ADA.

Subject to flag administration acceptance, the DNV rules can be applied as the flag administration’s approval basis or to significantly reduce the complexity of ADA.

Simplifying ship approval: DNV’s rules for ammonia and hydrogen fuels

DNV’s classification rules for ammonia and hydrogen (i.e. the “Gas fuelled ammonia” notation published in 2021 and the 2024 “Gas fuelled hydrogen” notation) provide structured, prescriptive requirements as far as possible to simplify ADA. Applying them helps reduce uncertainty in flag administration approval, streamlines design focus by aligning with expected risk assessments, and provides predictability to shipowners, ship designers and shipyards.

The paper describes step-by-step actions for obtaining approval. First, engage DNV and the flag administration early to clarify the approval basis. “DNV can help owners and yards in the initial contact with the flag administration to obtain necessary clarification regarding the approval scope and process,” says Hammer.

Second, align the design with DNV rules to ensure it provides a strong technical basis for risk evaluation. Third, tap into DNV’s extensive and growing experience from prior projects to anticipate what risk studies and documentation may be needed.

The paper also discusses measures to manage the new technical, human and organizational risks that both fuels bring compared to conventional fuels. DNV’s dedicated ship rules for each fuel type outline technical requirements and mitigation systems to integrate during design and operation.

Ofiniti to roll out e-BDNs for Golden Island methanol bunkering operations in Singapore

Ofiniti, a provider of digital solutions for maritime bunker operations, on Tuesday (29 April) said Singapore bunker supplier Golden Island Pte Ltd will adopt Ofiniti platforms for its expanding fleet operations.

Ofiniti said the move will lay the foundation for a digital multi-fuel future with Golden Island’s four new chemical tankers on order and Singapore-flagged bunker tanker Golden Antares, which will soon enter service.

As part of the transition, Ofiniti will roll out electronic Bunker Delivery Notes (e-BDNs), based on the recently published Technical Reference (TR) 129 on Methanol Bunkering, across Golden Island’s newbuilds and part of its existing fleet.

The Maritime and Port Authority of Singapore (MPA) and Enterprise Singapore (EnterpriseSG), through the Singapore Standards Council (SSC), on 10 March published TR 129 to provide a comprehensive framework for the safe and efficient use of methanol as an alternative fuel for bunkering operations.

Kenny Yap Song Jin, Low Carbon Solutions, Golden Island, said: “Launching our methanol bunkering operations is a major milestone, not just for Golden Island, but for Singapore’s journey toward multi-fuel readiness.

“By combining innovative low-carbon fuels with digital transparency, we set a new benchmark for safe, efficient, and sustainable marine fuel delivery.”

Ofiniti said it has supported suppliers through every stage of the industry’s transition, from conventional fuels to LNG, biofuels, hydrogen, and now, supporting methanol.

Tue Nielsen, Chief Executive Officer, Ofiniti, said: “I’m proud to welcome Golden Island to Ofiniti’s platforms.

“Their move signals a strong trust in our ability to support next-generation operations, and it reflects a broader shift in the market towards digital solutions built specifically for the realities of maritime fuels today and tomorrow.

“We are customer-obsessed, always trying to build in resilience to the way we are doing business.”

Manifold Times previously reported Golden Island’s plans to start bunkering trials of green methanol with its newbuild Singapore-flagged 7,999 dwt IMO type 2 bunker tanker from July.

Golden Antares was scheduled to depart a Chinese shipyard by late April and will lift green methanol produced by Hong Kong and China Gas Company Limited (Towngas) before returning to Singapore to begin bunkering trials.

In April, Ofiniti welcomed bunkering and marine fuel solutions provider Global Fuel Supply (GFS) to its FuelBoss platform as one of its newest customers.

GFS said it was proud to be the first physical supplier in West Africa to launch fully digitalised bunker operations with electronic bunker delivery note (e-BDN) via the FuelBoss platform.
