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.

Seaspan and Hapag-Lloyd complete first of five methanol vessel retrofit

Seaspan Corporation (Seaspan) and Hapag-Lloyd on Wednesday (3 June) announced the successful completion of the first of the five vessel conversions under their methanol retrofit programme with the delivery of Seaspan Yangtze.

From the early SAVER (Seaspan Action for Vessel Energy Reduction) programme to today’s CleanBlue initiative, Seaspan has committed over USD 230 USD million across 86 vessels, executing more than 550 efficiency and retrofit projects.

Following Seaspan Yangtze, the remaining vessels planned for retrofit under the programme are Seaspan Amazon, Seaspan Ganges, Seaspan Thames, and Seaspan Zambezi. Each retrofit is expected to reduce well-to-wake CO₂e emissions by approximately 30,000 to 50,000 metric tonnes per vessel annually when operating on low-carbon methanol, while also extending vessel lifespan and enhancing fuel flexibility.

“Decarbonisation is not just about building the fleet of tomorrow, it is also about unlocking the full potential of the fleet we have today. Retrofitting and upgrades on existing fleets play a practical, immediate, and economical role in accelerating shipping’s decarbonization journey,” said Bing Chen, Chairman, President and CEO of Seaspan. 

“Project SAVER CleanBlue highlights Seaspan’s strong customer partnerships, deep technical expertise, and unique platform integrated with JV partners, such as WattSpan Maritime Technology, in executing complex and large-scale retrofit projects.”

“The successful conversion of the Seaspan Yangtze together with the planned retrofit of its four sister vessels is another important step on our ambitious path towards net-zero fleet operations by 2045,” said Silke Lehmköster, Managing Director, Fleet, Hapag-Lloyd. 

“Together with Seaspan, we are demonstrating that retrofitting existing vessels for low-carbon methanol can be a practical way to reduce emissions in shipping.”

South Korean-led nuclear car carrier design secures LR backing

Classification society Lloyd’s Register (LR) on Tuesday (2 June) said it has teamed up with South Korean shipbuilding, marine services and nuclear research organisations to advance the development of a nuclear‑assisted car carrier concept. 

LR is working with Hyundai Heavy Industries, Korea Shipbuilding & Offshore Engineering (KSOE), Hyundai Glovis, G- Marine Service and the Korea Atomic Energy Research Institute (KAERI) on a joint development project (JDP) exploring an advanced small modular reactor (SMR) installation on a pure car and truck carrier (PCTC). 

The study focused on how a Molten Salt Reactor (MSR) could be physically and operationally integrated into a large vehicle carrier. Work examined the internal arrangement and segregation of the reactor system, shielding requirements, and the impact on cargo deck layout and vehicle capacity, alongside stability and trim implications linked to the reactor’s weight and positioning. 

The partners also assessed propulsion system configuration and power delivery, as well as operational flexibility compared with conventionally fuelled PCTCs, where trade routes and port calls can be tightly constrained. 

A key focus of the project has been safety. LR led hazard identification (HAZID) and preliminary risk assessment work, focusing on containment, onboard safety systems and potential operability constraints tied to nuclear technology at sea. 

The partners will mark the project milestone with an Approval in Principle (AiP) granting ceremony on 2 June at the LR stand during Posidonia 2026. 

Sung-Gu Park, President – North East Asia, Lloyd’s Register, said: “While nuclear propulsion is still at an early stage of development, this project shows the importance of building technical understanding now to support future progress. 

“Establishing feasibility at concept stage is a valuable step forward, particularly in areas such as cargo optimisation, vessel stability and integrated safety design.” 

Hong-Ryeul Ryu, CTO and Senior Executive Vice President at HD HHI, said: “With global environmental regulations becoming increasingly stringent and no definitive net-zero fuel yet available, SMR-powered ships can serve as a highly effective alternative, representing a pioneering next-generation maritime technology capable of complying with GHG emission regulations while allowing lifetime operation without refuelling, and HD HHI will remain at the forefront of sustainable maritime technology development.”
