The Samsung Heavy Industries (SHI) yard in South Korea will be constructing four “next generation” shuttle tankers for marine energy transportation, storage and production company Teekay.

The dual-fuel engines of these shuttle tankers are not only able to operate on liquefied natural gas (LNG) as the primary fuel, but also consume a mixture of LNG and recovered volatile organic compounds (VOC) as an energy source.

VOC is the gas evaporating from the oil cargo tanks during loading; by utilising the recovered VOC as fuel rather than venting it to the atmosphere the harmful emissions will be eliminated and the ships’ bunker needs will be significantly reduced, says Wartsila.

The concept means nitrogen oxide (NOx) emissions from the engines’ exhaust will be reduced by more than 80%, sulphur oxide (SOx) emissions will be almost entirely eliminated, while particulate emissions will be reduced by more than 95%.

It is also expected to produce a significant reduction in fuel consumption compared to conventional solutions. 

“Together with Teekay, we have developed a concept that takes the shuttle tanker sector into a new era, and which is further evidence of Wärtsilä’s ability to transform shipping by developing and utilising the very latest technologies,” says Roger Holm, President, Wärtsilä Marine Solutions.

“These ships will have tremendous operational flexibility with unmatched manoeuvring capability, and will achieve what all operators are striving for today, namely optimal economic and environmental performance.”

“This new shuttle tanker design will set new standards for both fuel consumption and CO2 emissions,” adds Terje Rusdal, Project Manager at Teekay.

Singapore-based Hung Ze chemical tankers to be equipped with Dealfeng rotor sails

Dealfeng, a Chinese provider of wind-assisted propulsion systems, on Tuesday (20 May) said it has assigned a cooperation agreement with Singapore-based shipowner Hung Ze Shipping.

The partnership will equip a new series of 14,000 DWT chemical tankers with Dealfeng® Rotor Sails. 

Each vessel will feature a 5m x 24m Dealfeng Rotor Sail installed on its forecastle deck. Collaborating with maritime software leader NAPA, the project will utilise route optimisation systems to maximise the efficiency of wind-assisted voyages, further enhancing fuel savings and emissions reduction while improving overall energy performance.

“The first vessel in the series is scheduled for delivery with the rotor sail system in the fourth quarter of 2025. Preliminary calculations indicate that the technology will achieve approximately 8% fuel savings on the vessel’s trading routes,” the company said in a social media post. 

The project marked Dealfeng’s first overseas commercial contract for its wind-assisted propulsion technology.

Dealfeng, a clean energy technology company specialising in the R&D, manufacturing, and EPC services of shipborne energy-saving systems, has long focused on developing Wind Assisted Propulsion Systems (WAPS). Its core product, the Rotor Sail, harnesses wind energy via the Magnus effect to provide auxiliary propulsion for vessels. 

Tailored to different ship types, the system offers fuel and carbon emission reductions of 5%–25%, with even greater efficiency under favorable wind conditions. Dealfeng’s Rotor Sail technology has obtained certifications from multiple classification societies and has been successfully deployed across numerous vessels, accumulating years of operational experience that validate its safety, reliability, and effectiveness.

Hung Ze operates a diverse fleet ranging from 5,000 DWT vessels to MR product tankers.

Anemoi, Hafnia, Guangzhou Shipyard and DNV to design rotor sails for MR tankers

Anemoi Marine Technologies on Thursday (15 May) announced a new partnership with Hafnia, Guangzhou Shipyard International (GSI), and DNV to develop the integration design of Rotor Sails suitable for installation on 50,000 dwt Medium-Range (MR) tanker vessels.

The companies signed a Joint Development Project (JDP) in April 2025 to develop a new generation of efficient and environmentally friendly Rotor Sail vessel designs to increase the efficiency of MR tankers within the wider global fleet.

As part of the project, Anemoi and Hafnia will undertake several engineering studies to establish specifications related to how Rotor Sails can be safely and efficiently installed on the deck of MR tankers, alongside additional electrical and control system layouts for these vessels. 

In addition, the studies will include calculations to examine how Rotor Sails can improve the Energy Efficiency Design Index (EEDI) and Energy Efficiency Existing Ship Index (EEXI) values of existing and future MR tankers.

GSI will apply its naval architecture and marine engineering principles to develop essential technical documentation for the new Rotor Sail’s design integration, while DNV will undertake an Approval in Principle (AiP) assessment to ensure that the design is feasible and verifies that no significant obstacles exist to prevent the design from being realized based on current and foreseeable regulatory and class requirements.

Nick Contopoulos, Chief Production and Partnerships Officer of Anemoi, said: “There is growing interest within the tanker sector for novel technology that can help reduce the carbon footprint of their vessels and increase their value, particularly as the MR tanker fleet is expected to grow in the coming years.”

“Our partnership with Hafnia, alongside GSI and DNV, will ensure a new generation of MR tankers that utilises Rotor Sails to improve their efficiency and sustainability credentials hits the water in the not-too-distant future.”

Mr Shao Guang Chi, Station Manager of Guangzhou Station at DNV Maritime, said: “WAPS, like Rotor Sails, are spreading throughout the industry, enabled by new materials, data and software, and evolving rules and regulations.”

“Across all segments, we still have room to improve vessel energy efficiency and WAPS have emerged as one of the most attractive tools for shipping to make immediate, impactful gains in this area.”
