Singapore-based maritime technology firm GILLS PTE LTD has been awarded approval in principle (AiP) from classification society Bureau Veritas (BV) for its underwater hull air lubrication system.

The AiP covers the design of the system and installation onboard vessels as reviewed against the Bureau Veritas Rules for Steel Ships NR 467 (as updated in January 2021).

GILLS, which stands for gas injected liquid lubrication systems, deploys NACA profiles developed by the National Advisory Committee for Aeronautics to create self-generating micro-bubbles for ‘turbulent modulation’ which has a ‘hull-tightening’ effect, reducing drag and energy requirements.

The self-generating nature of micro-bubble clouds with no requirement for air-compression and additional energy requirements is one of the features of the GILLS system.

The hull tightening effect of the GILLS technology is a phenomenon of the various factors and forces acting on the microbubbles generated by a GILLS vortex generator installed at the bow of the ship. These factors and forces can be identified as the following:

  • A ship’s forward movement
  • Creation of microbubbles by negative pressure and Kelvin Helmholtz Instability (KHI) exiting the vortex generator
  • The random shape of microbubbles with turbulence, eddies and vortices, from KHI
  • Buoyancy acting on the micro bubbles inducing an upward force
  • Shape of the hull

“The GILLS Air Lubrication System is a nature based innovative technology that not only uses the micro bubbles to reduce the drag, emissions, fuel and biofouling, but it also utilises the ship speed to generate a negative pressure and minimizes the required external compressor power,” explains Peter Kneipp, Managing Director of GILLS PTE LTD.

“We are greatly confident that GILLS will be a valuable contributor for practically every ship type to improve the EEDI /EEXI IMO Index. GILLS can also be retrofitted to existing ships as well as new vessels.”

“The collaboration with GILLS is timely as the industry seeks performance improvements in line with the EEXI energy efficiency targets. Pressure is building to find cost-effective solutions that work and can be financed,” said David Barrow, SE Asia Zone Vice-President for Bureau Veritas.

“The GILLS systems has been installed on an existing vessel for a number of years now and the vessel owners are confident of the fuel savings are approximately 10%.

“The next step is a full-scale measurement and a validation exercise led by Bureau Veritas Solutions (BVS) to identify confirmed performance.

“BVS, our consultancy arm, is also working with GILLS to assess the potential of access to Singapore ‘Green Funds’ to provide financial support to owners considering using such energy-saving systems.”

China Waterborne Transport Research Institute under the Ministry of Transport and China Transport News recently jointly launched a Methanol Fuel Shipping Supply Chain Innovation Alliance with 20 organisations spanning the shipping, port, energy, equipment, research and industry association sectors.

The alliance was officially announced during the main event of China Maritime Day 2026 on 11 July, where members also released a joint initiative to develop a collaborative methanol-fuelled shipping supply chain.

The alliance aims to implement China’s national strategy for green economic transformation and support the Ministry of Transport’s “One Network, Four Modernisations” initiative by building a safe, efficient, economical and reliable methanol marine fuel supply chain

Under the joint initiative, alliance members pledged to align with China’s national decarbonisation strategy by promoting methanol as a key pathway for the shipping sector’s green transition and optimising the industry’s energy mix.

The members also pledged to strengthen collaboration across the supply chain to improve coordination between bunker fuel production, transportation and end users while advancing technological innovation.

Lastly, the alliance will support the development of policies, planning and technical standards, promote resource sharing and joint research, and accelerate the large-scale adoption of methanol as a marine fuel.

The alliance brings together companies and organisations representing the entire methanol shipping supply chain.

Members include shipping and port members such as China Changjiang National Shipping (Group) Corporation, COSCO Shipping Bulk Co., Ltd., Shandong Port Group, and Wuhan Chuangxin Jianghai Shipping Co., Ltd.

Energy companies in the alliance include Sinopec Chemical Commercial Holding Company Limited and Methanex Corporation.

Marine fuel suppliers including Sinopec Fuel Oil Sales, China Marine Bunker (PetroChina), SIPG Energy (Shanghai) Co Ltd and Shenzhen Port Energy Development Co Ltd are also part of the alliance. 

Equipment manufacturers in the alliance are CSSC 711th Research Institute, CSSC Power (Group) Corporation Ltd and Chongqing Hongjiang Machinery Co Ltd.

Research, media and industry organisations participating in the alliance include the China Waterborne Transport Research Institute, China Transport News, and the Methanol Institute.

The Methanol Institute said methanol is moving beyond individual projects towards coordinated action across the entire value chain. 

“And China continues to play a leading role in advancing methanol as a marine fuel,” it said in a social media post.  

“We’re proud to work alongside our fellow alliance members to help strengthen the methanol supply chain and support the continued growth of methanol as a marine fuel.”

DNV awards TADC to Econowind for VentoFoil 3-Series

Dutch wind-assisted propulsion technology firm Econowind on Wednesday (15 July) said it has received a Type Approval Design Certificate (TADC) from classification society DNV for its VentoFoil 3-Series boundary layer suction wing. 

The company said the certification confirms compliance with DNV’s ST-0511 standard for Wind-Assisted Propulsion Systems and enables easier integration of VentoFoils on DNV-classed vessels worldwide. 

Econowind added that the approval accelerates the deployment of wind propulsion across the shipping industry.

“DNV is one of the world’s leading classification societies. This TADC gives DNV-classed shipowners confidence that VentoFoils meet the highest industry standards,” said Chiel de Leeuw, Chief Commercial Officer at Econowind. 

“It simplifies the approval process for both retrofits and newbuilds. VentoFoils are ideal for late-stage design integration and retrofit projects. This is an important milestone for Econowind and for the wider adoption of wind-assisted ship propulsion.”

The 3-Series VentoFoil is Econowind’s best-selling suction wing to date, with over 150 units sold. The system actively harnesses wind power to generate forward thrust, helping to reduce fuel consumption and mitigate FuelEU penalties. The system includes a tilting foundation, allowing the wings to be tilted down during port operations or in adverse weather conditions, making it a flexible solution.

The TADC applies to the 16-meter VentoFoil 3-Series product design and supports easy integration into DNV-classed vessels without repeating the full design assessment process. This enables shipowners, shipyards, and project teams to move more efficiently from concept to installation, reducing project complexity and accelerating deployment. 

Hasso Hoffmeister, Senior Principal Engineer at DNV Maritime, said: “It is a great pleasure to award Econowind this new certificate. WAPS have been going from strength to strength over the past few years, from 2022 the number of vessels in operation has increased five times, and we’ve now topped the century mark. 

“And with the current advances in technology, materials, and production capacity in the segment, we expect this to accelerate. So, while the wind always changes, the shipping industry is likely to be sailing strong for years to come.”

Econowind expects the DNV Type Approval Design Certificate to accelerate adoption of the VentoFoil, particularly among shipowners seeking proven, independently certified technology that can support fuel savings, emissions reductions, and decarbonization goals.

MS Heinz of HS Schiffahrt is among the first vessels to sail under this TADC.The company said the approval builds on Econowind’s growing installed base and further strengthens confidence in wind-assisted ship propulsion as a practical solution to address energy scarcity and high fuel prices. 

In addition to the 3-Series, Econowind offers the 5-Series for the deep-sea market.

Hapag-Lloyd and DSV sign 18,000 tonnes CO₂e decarbonisation deal

DP World on Tuesday (14 July) said its Americas ocean freight division will invest USD 1 million in Hapag-Lloyd’s Ship Green product under a new agreement that will enable customers to reduce ocean freight shipment emissions through verified carbon insets. 

The investment, which will be made over the next four quarters, is expected to avoid 4,762 metric tonnes (mt) of CO₂ using certified waste-based biofuels.

The investment will fund the use of certified waste-based biofuels in place of conventional marine fuels. These fuels can reduce greenhouse gas emissions by at least 84% compared with conventional marine fuels.

The emissions savings are calculated on a well-to-wake basis, meaning they account for the full lifecycle of the fuel, from production to use onboard the vessel.

Unlike traditional carbon offsetting, which compensates for emissions after they occur, Hapag-Lloyd’s Ship Green product enables carbon “insetting” – reducing emissions directly within the ocean freight supply chain. By replacing conventional marine fuels with certified waste-based biofuels, the product delivers measurable emissions reductions that are independently tracked and allocated to participating customer shipments.

Through this agreement, DP World will offer customers of its Americas ocean freight business verified carbon inset solutions that help reduce the emissions associated with their ocean freight shipments, supporting their broader supply chain decarbonization goals.

Terry Donohoe, Senior Vice President of Freight Forwarding for DP World in the Americas, said: “This partnership reflects how we are evolving our ocean freight business to deliver both commercial resilience and measurable sustainability outcomes. By working closely with Hapag-Lloyd, we’ve created a solution that not only advances our decarbonization ambitions but also generates tangible value for our customers through verified emissions reductions. It’s a strong example of how collaboration across the supply chain can unlock practical, scalable pathways to lower-carbon trade.”

This agreement reinforces DP World’s commitment to advancing sustainable trade and expanding practical, customer-focused solutions that help accelerate decarbonization across the global logistics value chain.
