“Do what we can now, with what we have!” This was the clear message on maritime decarbonization in a recent ‘Live from Singapore’ webinar organized by classification society DNV.

The panel explored strategies and practical solutions to decarbonize existing fleets, and how the industry can work together to solve this common challenge.

While fleet owners and operators are facing immense pressure, webinar panellists admitted that things will take time, and time is not on the side of shipping – and all other industries – to make the monumental changes to reach Net Zero goals, or at least halve emissions from international shipping by 50 percent until 2050.

Optimizing energy efficiency of existing fleets

Despite the huge challenges, panellists agreed there is a lot we can do right now that can make a big difference.

Ship operators can cut emissions immediately by introducing smart energy efficiency measures and it is possible to bunker low-carbon biofuels without having to make any changes to fuel tanks or engines. 

Anglo American’s Global Head of Shipping Peter Lye told the audience that his company was already working on a number of ways to reduce carbon intensity in its ocean freight operations. For example, it had successfully trialled (in mid-2021) a biodiesel blend, produced in Singapore from waste cooking oil, to power one of their charter vessels during a voyage to South Africa. 

Fellow panellist François-Xavier Accard, Managing Director of CMA CGM International Shipping, didn’t disagree, but made it clear that there was “not one solution”. Alternative fuels must be an important part of the mix, but we must not lose sight of the need for greater operational efficiency, including managing ship routing. He also called for more to be done to harmonize regulations for all in the maritime industry. 

DNV’s representative on the panel – Girish Sreeraman, Area Business Development Manager for Southeast Asia and the Indian Subcontinent –could not go past the word “collaboration” to sum up the importance of addressing decarbonization for the maritime sector. 

On alternative fuels, he made it clear that much more investment was needed, while optimization of vessels’ performance was a move in the right direction by IMO. With its Carbon Intensity Indicator (CII), ship operators needed more time to meet the reporting requirements.

More transparency needed

Sanjay Kuttan, Chief Technology Officer at the Global Centre for Maritime Decarbonization (GCMD), explained that it was vital to share data and lessons learned from the CII implementation. Without transparency, the wider industry was not going to be able to collectively apply what’s needed or adapt technology to make a meaningful difference.

Mr Accard from CMA CGM did caution to say that some of the data collected is “sensitive” and not all of it can be freely shared. Admittedly, it is important to collect all relevant data from the vessels, he said, regarding speed, fuel use, energy efficiency measures taken. But he insisted that the regulations must be clear and must be applied to all.  

Mr Lye of Anglo American pointed out that transparency and sharing of relevant data is important to customers and the whole supply chain. “They need to know that what we’re doing works for them. And they have a right to demand information if they are expected to be paying more.”

Biofuels to bridge the gap

Biofuels certainly received a lot attention from panellists and the virtual webinar attendees, whose questions were ably moderated by host Yvonne Chan.

It fell to Mr Kuttan to tackle many of the biofuel questions because his organisation GCMD is in the middle of a study which aims to establish an assurance framework that ensures supply chain transparency of drop-in biofuels, whose applicability can be extended to future drop-in fuels. 

He explained that it covers bio-LNG, bio-methanol, and green ammonia, when they become available in meaningful quantities, but also focuses on currently available biofuels, like biodiesel from used cooking oil and agricultural wastes.  

It was important to understand all aspects of biofuels, including availability, accessibility, supply and demand, as well as the potential to scale up production. 

Mr Kuttan said he is “very encouraged” by the results of the survey with webinar participants which showed that by far the majority were either already using biofuels, committed to, or planning to commit to biofuels in the near future.  

Verifying the supply chain of biofuels

The industry and its customers needed to be reassured that the use of biofuels can be measured for the genuine reduction of greenhouse gas (GHG) emissions, Mr Sreeraman said. 

If the source and the supply chain can be reliably verified, biofuels could become 100% carbon neutral fuel for vessels. There must be clear guidelines, though, and acceptable international standards.

Mr Kuttan was asked if he considered that the International Sustainability Carbon Certification (ISCC) was the best means to verify the source and supply chain of approved biofuels.

He told the audience that GCMD was fully evaluating all certification standards, including ISCC – which was designed in Europe to provide sustainability solutions for fully traceable and deforestation free supply chains – and has already been applied to biofuel supply in Europe and Asia. 

He also made the point that the GCMD study needs to show how the maritime industry can cope with the expected ”lower energy density” of biofuels, and how this impacts the accessibility of biofuels for bunkering in different parts of the world.

Ambition, collaboration, harmonization, action

Moderator Yvonne Chan concluded the very fruitful discussion by asking each panellist for a buzzword or two as a key take-away for all participants:

For CMA CGM’s François-Xavier Accard, it was the need for “harmonized regulations for all.”

Peter Lye, for Anglo American, summed it up in one word: “ambition’.

DNV’s Girish Sreeraman reinforced the need of “collaboration”. 

It was left to Sanjay Kuttan to elaborate – and take us back to the beginning – with his summary: “Bend the curve. Do what we can now, with what we have!”

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
