Odfjell conducts ‘first near’ carbon-neutral transatlantic voyage with sails and bio bunker fuel

Norway-headquartered Odfjell on Friday (25 April) said its chemical tanker Bow Olympus is about to complete the first near-carbon-neutral transatlantic voyage. 

The vessel is currently crossing the Atlantic powered by a combination of wind-assisted propulsion and a certified sustainable 100% biofuel, sourced from certified sustainable waste materials.

“This milestone voyage proves how existing technologies and fuels can be paired to accelerate deep-sea shipping’s transition to net zero emissions,” the company said. 

Real-time data from the voyage confirmed that this dual propulsion approach is not only technically feasible, but also impactful: The vessel’s GHG emissions on the current voyage meet the 2050 Fuel EU Maritime GHG intensity targets and IMO’s GFI Direct Compliance targets at least until 2044.

As Bow Olympus reached European shores last weekend, it has demonstrated that the dual propulsion solution is a realistic pathway to carbon neutrality for deep-sea shipping, 25 years ahead of time: The voyage showed a full 85% reduction in GHG intensity compared to conventional fuels, without technical investments or upgrades required to consume the fuel. 

In addition, the energy efficiency is improved by 15-20% by the use of sails.

The power of wind-assisted propulsion has been tested through Bow Olympus’ two first cross-Atlantic voyages. The four 22-meter suction sails have been operational under varying weather conditions, with the performance closely monitored by Odfjell’s crew and technology team on board and onshore.

“The results have surpassed our expectations,” confirmed VP Technology Erik Hjortland. 

“Even in good, but not perfect, wind conditions, we observed a 15 to 20% energy-saving effect. That translates to five tonnes of fuel saved per day, equivalent to a reduction of 15 tonnes of CO₂ emissions per day.”

“On certain parts of the current voyage, we have seen up to 40% fuel consumption reductions. These are very promising figures. We are thrilled to note that our initial calculations are confirmed and even exceeded.”

Using a new type of AI-based weather routing system allowed the five-year-old 49,000 dwt vessel to take full advantage of the prevailing wind conditions.

“One surprising finding is that even light wind as high as 15 degrees on the bow generates noticeable effect. This means that we can probably operate the sails more often than anticipated, positively affecting the already healthy return of investment figures. The sails also offer stabilizing and roll-damping effects,” Hjortland added

“Based on current data, we expect that the sails will continue delivering significant fuel savings on future deep-sea voyages in all basins.”

The bunkered biofuel was sourced from certified sustainable waste materials. The certification body is accredited by both IMO and EU.

Having exhausted most conventional upgrades, Odfjell is now focused on next-generation solutions—such as wind propulsion—to meet its 2030 goal of 57% carbon intensity reduction.

To move the needle beyond 57%, a fuel switch is required. Odfjell said it has chosen to remain flexible, keeping all doors open at a time when the marine fuel of the future for shipping remains undecided. 

“The choice of biofuel for this proof-of-concept voyage was done to demonstrate one of the pathways,” it added.

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.”
