A group of maritime firms including  airseas, HOULDER, i-tech, NAPA, NORSEPOWER, A&P, Anemoi, Ardmore Shipping, Bibby Marine Limited, Bunker Trace, CAMMELL LAIRD, e1 Marine, MSE International SEA SPEED Marine Consulting, Smart Green Shipping, stratumfive, Uber Boat, WightLink on Tuesday (2 November) issued an open letter calling for the international shipping industry to recognise more than green bunker fuels are needed for shipping’s decarbonisation:

The maritime industry cannot miss a huge opportunity to save time and money by investing in and applying energy efficiency and renewable propulsion technologies for newbuilds and retrofits.

These technologies, which are fully commercially available, extend the lifespan of the existing fleet and reduce the environmental footprint of the sector.

It’s not a question of choosing one or the other all energy efficiency and renewable propulsion technologies can complement low and zero carbon fuels; we will need them to create the zero carbon ship of the future, and reduce costs in the short term and long term. Simply put, these technologies make fuel and money work harder.

The damage done by our carbon emissions is cumulative and won’t be reversed by future fuels. Shipping can no longer run the race to be second. 

All measures taken now to reduce emissions through clean technologies give owners more time to plan for decarbonisation, while saving emissions and money now.

Shipping has abundant, innovative and fully commercially-available clean technologies that can significantly reduce fuel consumption and greenhouse gas emissions. It’s time to use them alongside new fuels. 

The shipping industry, the invisible backbone of our economy, is tackling the climate emergency with a growing sense of urgency and optimism even as it struggles with the disruptions of a global pandemic. However, energy and optimism needs to translate into action.

Action now means embracing the full range of innovative tools that are here, commercially ready, and deployable. 

Currently, regulations are encouraging the industry to do two things; to derate engines so vessels are forced to slow down and save fuel, and to gradually switch to more sustainable fuels, such as green hydrogen, methanol, ammonia, or biofuels. 

We commend the investments in this area, from fuel suppliers, shipowners and charterers alike, all of whom share the vision of a low-carbon future. However, given the scale and urgency of the climate emergency, we need to use all the tools available to us.

While important and impactful, focusing only on a narrow set of measures results in the shipping sector missing the opportunity to make big improvements NOW. We already have a huge range of energy efficiency and renewable propulsion technologies that both complement future fuels, and reduce carbon emissions. 

We already have a huge range of clean technologies delivering: wind propulsion, air lubrication, battery energy storage, hull coating technology, hydrodynamic energy saving devices, and voyage optimisation software, to name a few. 

The best part is, these technologies complement each other, and alternative fuels. Each vessel has its own combination of technologies that can drastically reduce its carbon footprint. These must combine with solutions for smarter operations and optimised voyages, that break down the misaligned incentives that can lead to ships sailing at speed only to wait in port. 

The shipping industry needs both efficiency technologies and future fuels. Neither provides the silver bullet for the existing fleet or the vessels of the future. Future fuels will be less energy-dense than current fuels, so ships will need more fuel to meet the same performance goals. 

Efficiency technologies can bridge this gap; making every drop of new fuel count will be essential. We can’t let the development of new fuels become an excuse for inertia. Immediate improvements are essential particularly as the current fleet and ships in the builder’s yard now will be on the water for decades for come. Our environment can’t sustain a “wait and see” strategy. 

The damage that we are doing is cumulative and irreversible and we all share a responsibility to take action. Many clean technologies have been deployed successfully for several years. Some translate the foundations of shipping such as sails, or hull coatings, into a true 21st Century solution. 

Others embrace big data, AI, advanced new materials and new ground breaking technologies. The history of seafaring is one of optimism, perseverance and ingenuity in the face of difficulty. No challenge is greater than the fight against climate change, and we should use all the tools we can today. 

The history of shipping shows that those who rose to the challenges prospered and those that either left it to others or ignored those challenges failed. We are calling for all shipping stakeholders and international authorities to expand their focus and attention. 

Long term innovation, research and development and the development of alternative fuels are key to decarbonising the maritime sector, BUT they are not the whole solution. Shipping needs to integrate the available efficiency and renewable propulsion technologies into their roadmap immediately with the following goals:

  • To ensure that we move to address the environmental challenges right away
  • To provide the opportunity to immediately drop emissions and fuel consumption while alternative fuels continue to scale up.
  • To provide the current fleet with an opportunity to keep pace with the rapidly accelerating environmental objectives coming from regulators, the market and the end consumer.

With the right support from investors and regulation, energy efficiency and renewable propulsion technology can inspire more ambitious targets and innovation, and ensure that shipping can continue as the lynchpin of a low-carbon global economy.

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.”
