ABS study suggests dual-fuel newbuildings having ‘decarbonisation advantage’ over conversion

Findings suggest conversion rises emission intensity between 13.7% and 32.6% over new construction based on data from vessels in the Avance Gas Holding fleet.

The American Bureau of Shipping (ABS) on Monday (20 September) issued a report suggesting a newbuilding could reduce carbon dioxide (CO2) emissions intensity by a third over the course of its operational life than an existing gas carrier converted to dual-fuel operations. 

The study used data based on vessels in the Avance Gas Holding Ltd. (AGH) fleet and compared potential greenhouse gas (GHG) emissions between a new-build, dual-fuel very large gas carrier (VLGC) and conversion of two AGH VLGCs over 20- and 25-year life cycles, including decommissioning. 

The findings suggest conversion increases emission intensity by between 13.7 and 32.6 % over new construction.

“Decarbonisation pathways are highly complex and challenging to evaluate how to produce the best strategy for reducing the GHG footprint over the lifetime of assets. These decisions matter both to the operational performance of shipping companies and to the environment, as well as to further investments as we embrace carbon economics,” Georgios Plevrakis, ABS Director, Global Sustainability.

“So, we are proud to be able to assist forward-looking operators, such as AGH, with making sense of the challenges they face with bespoke studies that shine a light on the best investment strategy.”

“ABS is a global leader in this area and is working with leading operators all over the world to develop decarbonisation pathways that deliver the best outcome for their fleets.”

The study compared 20- and 25-year lifecycle emissions from the conversion of AGH’s VLGC Monsoon from the diesel-fired SME engine and the diesel-fired SMC engine VLGC PROMISE to dual-fuel operations with new construction of a dual-fuel vessel with similar specifications to AGH’s LPG gas carrier. The LPG carrier was evaluated in both virgin steel and 70 % recycled steel formulations.

RESIZED bunker tanker singapore

The Maritime and Port Authority of Singapore (MPA) on Tuesday (22 September) said all 25 crew members from the Liberia-registered container vessel MSC HERMES III were rescued on 22 September 2026. 

The Maritime Rescue Coordination Centre (MRCC) Singapore coordinated the rescue after receiving a distress alert at about 8.45am (Singapore Time). 

“The vessel was within Singapore’s Maritime Search and Rescue Region (MSRR), about 300km east of Vietnam,” MPA said in a statement. 

MRCC Singapore immediately issued a broadcast requesting vessels in the vicinity to render assistance. Three vessels responded, and MSC RUBY recovered all 25 crew members after they had abandoned MSC HERMES III in a lifeboat. 

“All 25 crew members are safe, with no injuries reported,” MPA said. 

“MRCC Singapore is coordinating with the Vietnamese MRCC on arrangements for the rescued crew members to return safely to shore.”

GCMD, Equinor to combine expertise on alternative bunker fuels, decarbonisation solutions

The Global Centre for Maritime Decarbonisation (GCMD) and Equinor on Tuesday (22 September) announced a five-year Impact partnership.

The partnership brings together GCMD’s capabilities in conducting real-world maritime pilots with Equinor’s experience as a charterer, energy provider and developer of low-carbon solutions.

Together, the organisations will leverage their complementary expertise to help address technical and operational gaps in scaling alternative marine fuels and supporting the development and uptake of other maritime decarbonisation solutions.

GCMD’s work on alternative fuels, including biofuels, ammonia and methanol, focuses on two critical aspects of deployment: operational safety and robust monitoring, reporting and verification (MRV). Its pilots and studies are generating operational data to support safe bunkering and handling of these fuels. 

At the same time, its assurance work seeks to strengthen confidence in quantity, quality and GHG emissions abatement.

“Equinor brings extensive experience as a vessel charterer and marine fuel supplier. This includes chartering dual-fuel LNG, LPG and methanol tankers, testing and using biofuels and supplying methanol to the maritime sector,” GCMD said.

Equinor is also piloting the use and supply of ammonia as a marine fuel, contributing to the development of associated safety, regulatory and bunkering arrangements.

Combining these perspectives can help address practical barriers to alternative fuels deployment while strengthening assurance across emerging marine fuel value chains.

Beyond alternative fuels, GCMD is working to accelerate the adoption of solutions that can reduce emissions from the existing fleet, including energy efficiency technologies (EETs) and onboard carbon capture and storage (OCCS).

GCMD’s work on EETs includes quantifying real-world fuel savings from technologies such as wind-assisted propulsion systems and developing financing mechanisms to scale their adoption. In OCCS, Project CAPTURED demonstrated an end-to-end value chain for onboard captured and liquefied CO₂, generating evidence that contributed to the recognition of captured CO2 under the EU ETS and in-principle support at the IMO for recognising carbon mineralisation as permanent storage.

Equinor brings decades of experience in offshore CO₂ storage, including its role in the development and operation of Northern Lights, the world’s first cross-border CO2 transport and storage facility, where liquefied CO₂ is transported by ship to an onshore receiving terminal before it is sent by pipeline for permanent geological storage beneath the North Sea.

Through the partnership, GCMD and Equinor will explore opportunities to combine their respective capabilities and experience to support the deployment and scaling of maritime decarbonisation solutions.

Wah Kwong NatPower, AREL partner on maritime electrification in Hong Kong

Wah Kwong NatPower (WK NatPower) on Tuesday (22 September) said it has signed a Memorandum of Understanding (MoU) with Aberdeen Restaurant Enterprises Limited (AREL) to explore the electrification of piers, vessels and supporting energy infrastructure in the Aberdeen area of Hong Kong.

Against the backdrop of the HKSAR Government’s latest policy direction to advance green shipping, smart port development and shore power infrastructure, WK NatPower and AREL will explore the development of an integrated marine electrification ecosystem in the Aberdeen and Shum Wan areas. 

The collaboration will examine opportunities to deploy shore power facilities, vessel charging infrastructure and battery energy storage solutions, alongside the development of electric vessels for future transport and tourism services.

The initiative supports Hong Kong to become a leading hub for sustainable maritime innovation while contributing to the revitalisation of one of the city’s most iconic waterfront communities. As an initial phase of the collaboration, the two parties will explore the opportunity for the construction of a series of electric vessels and transport vessels. 

The initiative will also examine the potential deployment of the ApliAber® electric vessel fleet as a new benchmark for sustainable waterfront mobility and hospitality experiences in Hong Kong.

Vincent Ni, General Manager of WK NatPower, said: “This MoU marks an important step in supporting Hong Kong’s marine energy transition. Aberdeen has long been an iconic part of Hong Kong’s maritime heritage, and we are delighted to explore opportunities to develop integrated shore power and vessel electrification solutions that can support a cleaner and more sustainable future for the harbour.”

Wong Tai Yu, Director of AREL, said: “Through this collaboration, we look forward to exploring practical ways to introduce cleaner energy, electric vessels and sustainable waterfront experiences, while supporting the revitalization of Jumbo Kingdom® for future generations.”
