Classification society DNV on recently published a Maritime Impact article on Knut Ørbeck-Nilssen, DNV Maritime’s CEO, sharing his reflections on the latest findings of the new Maritime Forecast to 2050 report and how maritime can get closer to achieving upcoming decarbonization goals: 

Knut Ørbeck-Nilssen, CEO, DNV Maritime, says shipping must invest in the exploration and development of technological solutions that improve energy efficiency to reduce greenhouse gas emissions until carbon-neutral fuels become available.

Decarbonization is one of the greatest challenges facing shipping. Following a slow start, decarbonization aspirations have been embraced by the maritime industry. IMO goals have been set, notably full-scale decarbonization by or around 2050, a 20% emissions reduction by 2030, and a 70% reduction by 2040.

While these moves have been widely welcomed, it’s time to get real. Setting goals is the easy part. Achieving them is extremely difficult, bordering on the impossible. Indeed, a pragmatic assessment of the shipping industry today indicates that decarbonization is slowing down, not accelerating.

Let’s look at the facts.

The costly transition to carbon-neutral fuels

Full decarbonization will require a large-scale transition to carbon-neutral fuels. This is a huge challenge requiring the construction of new vessels and the retrofitting of existing vessels to enable them to operate on, likely very expensive, green versions of fuels. In a global economy already heavily burdened by inflation and high interest rates, the extra costs associated with this transformation are about as appealing to shipowners as a leaky hull.

Indeed, in an era of higher freight rates, shipowners are understandably seeking to harvest profits and have little incentive to join the queue for limited yard space. While around 50% of new orders today are for ships with dual-fuel capability, constructing them comes at a premium which is difficult to pass along the supply chain. The happy hour for methanol appears to be over already, and the reality is that 93% of the global fleet is still running on conventional fuels.

Even if this technological shift on board the vessels is eventually successful, global supplies of carbon-neutral fuels remain miniscule and shipping needs to compete with other industries for its share. Fuel suppliers are reluctant to invest billions of dollars in projects for which demand is uncertain and, so far, the exponential growth in supply that we need is nowhere to be seen.

But all is not lost yet.

Harnessing technology and cultural changes to drive energy efficiency

Using simulations, this year’s Maritime Forecast to 2050 report by DNV estimates that fuel consumption can be reduced by between 4% and 16% by 2030 using energy efficiency measures.

The first few percentage points can be achieved quite easily. Many maritime companies have already shown that by instilling cultural changes throughout an organization, and by encouraging crew members to seek efficiencies through their day-to-day operations, fuel consumption can be reduced, and emissions reductions of around 5% can be achieved.

However, going to the next level and reaching double-digit energy efficiency requires technological solutions. Technologies like wind-assisted propulsion and waste-heat recovery systems, to name just a few, have already been proven to deliver tangible emissions reductions.

But technology can do even more.

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.”
